Sliding/tilt sunroof with glass moonroof*
The options and control procedures are essentially the same as those previously described for the sliding/tilt sunroof. In order to open the raised roof, press the control switch towards "Open" until the roof has reached the desired position. The headliner insert slides back somewhat when you raise the sunroof. When the sunroof is opened the headliner retracts with it. The headliner will then automatically remain in its retracted position, but can be repositioned as desired.
Power loss or malfunction
After interruptions in the electrical supply (when the battery is disconnected, for instance), the sunroof may only lift. To reinitialize the mechanism: 1 Raise the sliding/tilt sunroof all the way. 2 Press and hold the switch for approx. twenty seconds. In the event of an electrical malfunction, you can also operate the sliding/tilt sunroof manually. Refer to page 198.
If the sliding/tilt sunroof encounters resistance at a point roughly past the middle of its travel when it is closing, the closing cycle is interrupted and the sliding/tilt sunroof will open again slightly.

Manual transmission

390de042
The parking brake is primarily designed to prevent the vehicle from rolling while parked. It operates against the rear wheels.

BMW 525i, BMW 530i

Every time you shift gears, always depress the clutch pedal all the way down, pushing the manual-shift gear lever into the respective end position. Depress the clutch even when starting the engine, otherwise, a lock will prevent the engine from being started. The shift lever's neutral gate (dot in the illustration) is located between 3rd and 4th gears. When shifting from each gear into "Neutral," the shift lever returns automatically to this neutral position because of its spring loading.

To engage

The lever engages automatically and the "PARK BRAKE" or "BRAKE" (in Canada "P") indicator lamp comes on in the instrument cluster in ignition key position 2. Refer to pages 22 and 23.

To release

Pull up slightly on the lever, press the button and lower the lever.

When shifting gears in the 5th/ 6th-gear plane, be sure to press the gear lever to the right in order to prevent inadvertent selection of a gear in the 3rd/4th-gear plane.<

Reverse

380de044
Select "Reverse" only when the vehicle is stationary. Press the shift lever to the left to overcome the resistance. As you do this, the backup lamps will turn on automatically when the ignition key is in position 2. Do not hold the vehicle in place on slopes by slipping or "riding" the clutch. Use the parking brake instead. Riding the clutch causes increased clutch wear.<

transmission*

The automatic transmission of your BMW is equipped with Adaptive Transmission Control (ATC), a system which reacts with precision to your individual driving style and the driving conditions. To achieve this, different driving programs are automatically engaged. For details concerning ATC, please refer to the chapter describing "Advanced technology" on page 206.

Selector lever positions

PRND432 The transmission range display varies according to model (refer to illustrations).

Range selection

A detent prevents inadvertent shifts into some selector lever positions. To release the shift-lock mechanism, press the button on the front of the selector handle (arrow). While the vehicle is stationary and before shifting out of "Park" or "Neutral," depress the footbrake in order to disengage the selector lever's lock mechanism (Shiftlock). Hold the footbrake down until starting off. Otherwise the vehicle will "creep" when a drive position is engaged.<

Starting engine

The selector lever must be in "Park" or "Neutral" before it is possible to start the engine.

Automatic transmission*
Before leaving the vehicle when the engine is running, shift the selector lever to the "Park" or "Neutral" position and apply the parking brake. The vehicle could move if this is not done. Never leave the vehicle unattended with the engine running. An unattended vehicle with a running engine represents a potential safety hazard. If you should accidentally select "Neutral" while traveling at high speed, remove your foot from the accelerator pedal immediately. Allow the engine speed to drop to idle before selecting the desired drive position. Damage could otherwise occur due to excessive engine speed.<
Select "Neutral" only if your journey is interrupted for a long period.
This position is designed for driving under all normal operating conditions. All forward gears are available.

"Kickdown"

In the "Kickdown" mode, you achieve maximum performance. To activate this mode, depress the accelerator pedal beyond the fullthrottle position, at which a resistance point must be overcome.

If the indicator lamp does not go out, you can place the selector lever in all positions. However, the vehicle will now only drive forward with limited gear selection. Under these circumstances, avoid extreme engine loads and consult the nearest BMW center. Do not work in the engine compartment when a drive gear (forward or reverse) is engaged. If you do this, the vehicle could move.< For jump-starting, towing and towstarting, refer to pages 200 and 201.
Electronic transmission control module
If the indicator lamp comes on or if the message "TRANS. FAILSAFE PROG" appears in the Check Control*, there is a malfunction in the transmission system. Bring the vehicle to a stop, select the "Park" position, apply the parking brake and shut the engine off (ignition key position 0). Restart the engine after a few seconds. If the indicator lamp goes out again after a few seconds, the normal transmission functions have been restored. You may continue to drive as usual.

Distance Control (PDC)*

Acoustic signals

The distance to an object is indicated by a high beeping sound in the front and a low beeping sound in the back. As the distance between vehicle and object decreases, the intervals between the tones become shorter. A continuous tone indicates the presence of an object less than 1 ft (30 cm) away. The warning signal will be canceled after approx. 3 seconds if the distance to the obstruction remains constant during this time (if you are moving parallel to a wall, for instance). Malfunction in the PDC system: The indicator lamp flashes and a brief continuous signal tone is heard > when the PDC system is actived via the button > when you first select reverse or move the selector lever into the "R" position after switching on the ignition > when there is a malfunction while the PDC system is active. Switch the system off and have the cause of the malfunction corrected by your BMW center.
The PDC assists you when you are parking. A signal warns you of the real distance to an obstacle. To do this, four ultrasonic sensors in the front and rear bumpers measure the distance to the nearest object. The monitoring range for the front and both rear corner sensors extends approx. 2 ft (60 cm) beyond the bumper. The range for the center rear sensors extends approx. 5 ft (1.50 meters).
Turn on manually Automatic operation
The system starts to operate automatically approx. one second after you select reverse or move the selector lever into the "R" position with the ignition key in position 2. Press the button (arrow), the indicator lamp comes on. After driving more than approx. 160 ft (50 meters) or exceeding approx. 20 mph (30 km/h), the system switches off and has to be switched back on when you want to use it again.

390us713

Park Distance Control (PDC)*
The PDC does not remove the driver's personal responsibility for evaluating the distance between the vehicle and any obstacles. Even when sensors are involved, there is a blind spot in which objects cannot be detected. This applies especially in those cases where the system approaches the physical limits of ultrasonic measurement, as occurs with tow bars and trailer couplings, and in the vicinity of thin and painted objects. Certain sources of sound, such as a loud radio, could drown the PDC signal tone.< Keep the sensors clean and free of ice or snow in order to ensure that they continue to operate effectively. Do not apply high pressure spray to the sensors for a prolonged period of time. Maintain an adequate distance of more than approx. 4 in (10 cm).<

Stowing cargo
When transporting loads in your BMW: > Position heavy loads as far forward as possible directly behind the backrests or the luggage compartment partition panel and at the bottom (the illustration shows the sport wagon). > Cover sharp edges and corners > Do not pile objects higher than the top edge of the backrest. > Pull out the partition net* (refer to page 132) and ensure that carried items cannot pass through the partition net. > For very heavy loads when the rear seat is not occupied, secure each safety belt in the opposite buckle.

Securing the load

> Secure smaller, light pieces with the retaining straps or a luggage net *, or use elastic straps (refer to page 46). > For large, heavy pieces, visit your BMW center for load-securing devices*. Lashing eyes are provided at the corners of the luggage compartment for attaching these load-securing devices (the illustration shows the sport wagon). > Comply with the information enclosed with the load-securing devices.

Information for your safety
Not even ABS can suspend the laws of physics. The consequences of brake applications with inadequate safety clearances between vehicles, excessive speed or if aquaplaning occurs are always the responsibility of the driver. You should never allow the added safety margin of ABS to mislead you into taking risks of any kind. Do not make any modifications to the ABS system. Service procedures on ABS are to be performed by authorized technicians only.<
When driving in wet conditions and in heavy rain, it is effective to apply light pressure to the brake pedal every few miles (kilometers). Watch traffic conditions to ensure that this maneuver does not endanger other road users. The heat which is generated by the brake applications helps to dry the brake pads and rotors. Maximum braking force is obtained while the wheels continue to rotate, peaking when the wheels remain on the verge of locking without actually doing so. ABS maintains this state automatically. If the ABS fails, you should revert to the staggered braking technique described below (refer to page 147). Extended or steep mountain descents should be driven in the gear in which only minimal periodic brake applications is required. This avoids excessive strain on the brakes and possible impairment of the braking effect. The braking effect of the engine can be further increased by downshifting, into first gear, if necessary. In the manual mode of the automatic transmission, you can also downshift into first gear. Refer to page 76. Should engine braking prove inadequate, you should still avoid extended, continuous braking. Instead of maintaining low to moderate pressure over an extended period of time, you should decelerate by applying more substantial pressure to the brake pedal (watch for following traffic!), then releasing the pedal, then repeating the application. This staggered braking technique allows the brakes to cool in the intervals between active braking phases, preventing overheating and ensuring that full braking capacity remains available at all times. Do not coast with the clutch depressed or with the transmission or selector lever in Neutral. Do not coast with the engine shut off. The engine provides no braking effect when the clutch is depressed or the transmission is in neutral, and there is no power-assist for braking or steering when the engine is not running. Never allow floor mats, carpets or any other objects to protrude into the area around the accelerator, clutch and brake pedals and obstruct their movement.<
If you apply the brakes rapidly, this system automatically produces the maximum braking force boost and thus helps to achieve the shortest possible braking distance during "panic stops." All of the benefits of the ABS system are exploited under these circumstances. Do not reduce the pressure on the brake pedal for the duration of the brake application. When the brake pedal is released, the DBC is deactivated. In the event of a malfunction, the yellow warning lamp comes on. Conventional braking efficiency is available without limitations. Have the system checked and repaired at your BMW center as soon as possible. For "Information for your safety" covering the ABS system, refer to page 144. This information also generally applies for DBC.<

You can touch up small areas of damage with BMW spray paint or a BMW touch-up stick. The paint color code for your vehicle is provided on a sticker located on the right hand side under the hood and on the first page of your Service and Warranty Information Booklet. Damage caused by flying stones, scratches, etc., must be touched up without delay to prevent rust from forming. If corrosion has started to form in an area with paint damage, remove all rust and clean the area. Then prime the area with a BMW Primer Stick. Finally, apply the finish coat. After a few days, polish and protect the touched-in areas. More extensive paint damage should be repaired professionally in accordance with the manufacturer's instructions. Your BMW center uses original BMW finish materials in accordance with approved repair procedures.

Window care

You can use window and glass cleaner to clean inside window surfaces and mirrors without smearing and streaking. Never use polishing pastes or abrasive (quartz) cleansers on mirror lenses. When caring for break-resistant security glass*, observe the following instructions: The inner surface of the side windows is coated with a plastic film. For this reason, do not affix any decals or adhesive stickers on the inside of these windows unless they are to be placed there permanently. Wash the glass with clean water. If necessary, you may add a commerciallyavailable mild household cleaner. Do not use abrasive cleaners. If the windows are fogged or iced over, treat them with an anti-misting cloth or a deicer spray do not use an ice scraper.< Clean the wiper blades with soapy water. The wiper blades should be replaced twice a year, before and after the cold season. Use only wiper blades which have been approved by BMW.<
Caring for other vehicle components and materials
Light-alloy wheels should be treated with alloy wheel cleaner, especially during the winter months. However, do not use aggressive products containing acids, strong alkalis or abrasives. Do not use steam cleaners operating at temperatures above (60 6). (Follow the manufacturer's instructions.) If your vehicle has chrome parts * such as window moldings, door handles or other items, clean these parts carefully with ample clean water, especially if they have an accumulation of road salt. Use a chrome polish for an additional treatment. Plastic components, vinyl upholstery, headliners, lamp lenses, the clear cover of the instrument cluster and components with a sprayed dull black surface can be cleaned with water (add plastic cleaner as required). Do not allow moisture to soak through the seats or headliner. Never use solvents such as lacquer thinner, heavy-duty grease remover, fuels, etc.

Shift into 1st or reverse (selector lever in Park with automatic transmission) and engage the parking brake. All passengers should be outside the vehicle and well away from your immediate working area (behind a guardrail, for instance). If necessary, set up your warning triangle or portable hazard warning lamp on the roadside at an appropriate distance from the rear of the vehicle. Comply with all safety guidelines and regulations. Change the wheel only on a level, firm surface which is not slippery. Avoid jacking the vehicle on a soft or slippery support surface (snow, ice, loose gravel, etc.), since it could slide sideways.

Behind the valve stem in every wheel, there is an electronic chip which is designed for severe-duty applications and long service life. It contains a pressure sensor, a transmitter and a battery. The pressure is measured in extremely short time intervals and then transmitted by a radio signal. If an irregularity is detected, the transmission rate is increased.
The Tire Pressure Control system (RDC) assumes the task of regular tire pressure checks for you. The tire pressure is monitored at all four wheels, even when the vehicle is moving.

rear suspension
The illustration shows the rear axle of the sedan. With the lightweight, compact rear axle of the sport wagon, the shock absorbers are positioned at an angle.

390de114

The control arms on the patented integrated aluminum rear axle assembly are not mounted directly on the body. They are mounted elastically on a chassis sub-frame which is joined in turn with elasticity to the vehicle body. The resulting double elastic suspension system effectively absorbs the forces resulting from bumps and road surface irregularities. The compliance rates of the integrated rear axle assembly's control arm mounts have been precisely calibrated to help provide supplementary adjustment in the tracking angle of the rear wheels (programmed self-steer effect). The ultimate result is enhanced safety and control under all conditions.
The level control system for the rear axle maintains constant ground clearance of your vehicle, even when carrying a load. To achieve this, the vehicle is equipped with air struts at the rear axle instead of conventional shock absorbers and steel suspension springs. With the help of two sensors, an electronic control unit calculates the height of the body at all times and, if it is required, it allows air which is generated in a compressor to flow into the air springs. As a result of the pressure increase in the air springs, the level control system ensures not only constant ride height, but also ride comfort which is independent of the load the vehicle is carrying.

Xenon lamps provide significantly improved visibility, especially during adverse weather conditions and driving situations (driving at night in heavy rain or through road repair areas where there are no lane markers, for instance). Vehicles with xenon lamps are equipped with automatic headlamp range control. As a result, the highway is always optimally lighted, regardless of load conditions, and drivers in oncoming traffic are not blinded. Xenon lamps make a significant contribution to highway safety since other highway users, or bicyclists and motorcyclists in the right lane, and pedestrians are more easily detected.

Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor may be switched off at the same time to prevent a false alarm from being triggered (in garages with elevator ramps, for instance), or when the vehicle is transported by trailer or train: Lock the vehicle (arm the alarm system) twice in succession: Press button 2 on the remote-control transmitter twice (refer to page 38), or turn the key in the door lock to the right (lock) twice in succession (refer to page 36). The indicator lamp lights up briefly and then flashes continuously. The tilt alarm sensor and the interior motion sensor are deactivated for as long as the system remains armed.

Interior motion sensor

The illustration depicts the transmitter and receiver of the interior motion sensor. In order for the interior motion sensor to function properly, the windows and sliding/tilt sunroof must be completely closed. Nevertheless, you should deactivate the interior motion sensor (refer to the previous column) if you intend to leave the windows or sliding/tilt sunroof open.

Otherwise, an object might not touch the contact strip in some situations (very thin objects, for instance). You can override this safety feature by pressing the switch beyond the resistance point and holding it. Because the power windows are sealed at high pressure to prevent wind noise when closed, a powerful motor is required for efficient closing. When closing the windows, always be sure that they are not obstructed in any way. Unsupervised use of these systems can result in serious personal injury. Remove the ignition key to deactivate the electric power windows whenever you leave the car. Never leave the keys in the car with unsupervised children. Never place anything that could obstruct the driver's vision on or next to the windows.<

Electric power seats

Correct sitting posture
To reduce strain on the spinal column, sit all the way back in the seat and rest your back fully against the backrest. The ideal sitting posture is achieved with your head extending from your spine in a straight line. For long-distance driving, you may wish to increase the backrest tilt-angle slightly to reduce muscular tension. Please remember that you should always remain able to grasp the entire periphery of the steering wheel without straightening your arms.
For maximum safety, please comply with the following instructions when adjusting a seat: Never try to adjust your seat while operating the vehicle. The seat could respond with unexpected movement, and the ensuing loss of vehicle control could lead to an accident. Wear the safety belt firmly against your body at all times. In the event of a frontal impact, a loose lap belt could slide over your hips, leading to abdominal injury. In addition, the safety belt's restraint effectiveness is reduced if the belt is worn loosely. Never ride with the backrest reclined to an extreme horizontal angle (especially important for front passengers to remember). Keep the backrest relatively upright to minimize the risk of "sliding under" the safety belt and sustaining injury in an accident. Do not slide the seats to the rear when the vehicle is at an extreme angle (on garage ramps or steep slopes, for instance), to prevent the shoulder strap's automatic height adjustment mechanism from disengaging.<

Distance Control (PDC)*

Acoustical signals

The distance to the nearest object is indicated by a tone sounding at various intervals. As the distance between vehicle and object decreases, the intervals between the tones become shorter. A continuous tone indicates the presence of an object less than 1 ft. (30 cm) away. The warning signal will be canceled after approx. 3 seconds if the distance to the obstruction remains constant during this time (if you are moving parallel to a wall, for instance). System malfunctions will be indicated by a continuous high-pitched tone when the system is activated the first time. Please have the cause checked and corrected by your authorized BMW center. The PDC does not remove the driver's personal responsibility for evaluating the distance between the vehicle and any obstacles. Even when sensors are involved, there is a blind spot in which objects cannot be detected. This applies especially in those cases where the system approaches the physical limits of ultrasonic measurement, as occurs with tow bars and trailer couplings, and in the vicinity of thin and painted objects. Certain sources of sound, such as a loud radio, could drown the PDC signal tone.< Keep the sensors clean and free of ice or snow in order to ensure that they continue to operate effectively. Do not apply high pressure spray to the sensors for a prolonged period of time. Maintain an adequate distance of more than approx. 4 inches (10 cm).<
The PDC assists you when you are parking. A signal warns you of the real distance to an obstacle. To do this, four ultrasonic sensors in the rear bumper measure the distance from the nearest object. The monitoring range for the two corner sensors ends approx. 2 feet (60 cm) beyond the respective bumper. The range of the two middle sensors is approx. 4.9 feet (1.50 meters) outward. The system starts to operate automatically about one second after you select reverse with the ignition key in position 2. It is similarly deactivated when you engage reverse gear or move the selector lever position from the "R" position.

Treadwear

The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one-half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.<
The temperature grades are A (the highest), B and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

replacement

Tire age
The date on which the tire was manufactured is indicated by the code on the sidewall: DOT. 129 indicates that the tire was manufactured in Week 12 of 1999. BMW recommends the replacement of all tires when the tires are no more than 6 years old, even if a tire life of 10 years is possible. Spare tires over 6 years old should be used only in case of emergency. Such a tire should be replaced by a new tire immediately, and should not be mounted together with new tires.

Tire rotation

Between the axles
The tread wear patterns at the front end differ from those at the rear the actual patterns will vary according to individual driving conditions. In the interests of safety and maintaining optimal handling characteristics, interaxle tire rotation is not recommended. If a proposed interaxle rotation of tires is based on economic considerations, one should consider whether the costs for the rotation are likely to be recaptured by any increase in the service life of the tires which might be realized. In principle, interaxle tire rotation should be performed at short intervals, with a maximum of 3,000 miles (5,000 km). Consult your authorized BMW center for more information.

Caring for the vehicle finish
Regular washing is a preventive measure against long-term effects from substances that are harmful to the vehicle's finish, especially if you drive your vehicle in areas with high levels of air pollution or aggressive natural substances (tree resins, pollen). Nevertheless, you should immediately remove especially aggressive substances. Failure to do so can lead to changes in the paint's chemical structure or to discoloration. Gasoline spilled during refueling, oil, grease and brake fluid should always be cleaned away immediately, as should bird droppings (finish damage). Any contamination remaining on the surface of the vehicle will be especially conspicuous after washing. Use cleaning fluid or alcohol with a clean cloth or cotton pad to remove. Remove tar spots with tar remover. After cleaning, the affected areas should be waxed to ensure continued protection. Use cleaning and car-care products that you can obtain at your BMW center.<
Protect the finish using carnauba or synthetic-based waxes only. The best way to determine when the finish needs to be waxed is by noting when water stops beading on the surface. You can use a glass cleaner to remove any wax or silicone that may have been left on the windows during waxing. Use cleaning and car-care products that you can obtain at your BMW center.<
You can touch up small areas of damage with BMW spray paint or a BMW touch-up stick. The paint color code for your car is provided on a sticker located on the right hand side under the hood and on the first page of your Service and Warranty Information Booklet. Damage caused by flying stones, scratches, etc., must be touched up without delay to prevent rust from forming. If corrosion has started to form in an area with paint damage, remove all rust and clean the area. Then prime the area with a BMW Primer Stick. Finally, apply the finish coat. After a few days, polish and protect the touched-in areas. More extensive paint damage should be repaired professionally in accordance with the manufacturer's instructions. Your BMW center uses original BMW finish materials in accordance with approved repair procedures.

Caring for other vehicle components and materials
Light-alloy wheels should be treated with alloy wheel cleaner, especially during the winter months. However, do not use aggressive products containing acids, strong alkalis or abrasives. Do not use steam cleaners operating at temperatures above 1407 (606). Follow the manufacturer's instructions. If your vehicle has chrome parts* such as window moldings, door handles or other items, clean these parts carefully with ample clean water, especially if they have an accumulation of road salt. Use a chrome polish for an additional treatment. Plastic components, vinyl upholstery, headliners, lamp lenses, the clear cover of the instrument panel and components with a sprayed dull black surface can be cleaned with water (add plastic cleaner as required). Do not allow moisture to soak through the seats or headliner. Never use solvents such as lacquer thinner, heavy-duty grease remover, fuels, etc. Rubber components should be cleaned with water only; a rubber treatment or silicone spray may also be applied. The safety belts should be cleaned with a mild soap and water solution without being removed from the car. Never attempt chemical or dry cleaning, as damage to the belt fabric could result. After cleaning, never allow the inertia reel to retract the belts until they are completely dry. Dirty safety belts prevent the inertia reel mechanism from retracting the strap properly, and thus constitute a safety hazard. Heavily soiled floor carpets and mats* can be cleaned with an interior cleaner. The floor mats can be removed from the vehicle for cleaning. Please use only a damp cloth to clean wooden fascia panels and components. Follow up by drying with a soft cloth. Use cleaning and car-care products that you can obtain at your BMW center.<

195n Xenon lamps provide significantlyimproved visibility, especially during adverse weather conditions and driving situations (driving at night in heavy rain or through road repair areas where there are no lane markers, for instance). Vehicles with xenon lamps are equipped with automatic headlamp range control. As a result, the highway is always optimally lighted, regardless of load conditions, and drivers in oncoming traffic are not blinded. Xenon lamps make a significant contribution to highway safety since other highway users, or bicyclists and motorcyclists in the right lane, and pedestrians are more easily detected.

To achieve this, the vehicle is equipped with air struts at the rear axle instead of conventional shock absorbers and steel suspension springs. With the help of two sensors, an electronic control unit calculates the height of the body at all times and, if it is required, it allows air which is generated in a compressor to flow into the air springs. As a result of the pressure increase in the air springs, the level control system ensures not only constant ride height, but also ride comfort which is independent of the load the vehicle is carrying.
In a xenon lamp, an electric arc replaces the filament in order to generate intense illumination. A gas mixture in a quartz glass tube with metal vapor is ignited by a high electric voltage. The arc that is generated is then sustained by a lower voltage. When the lamp is turned on, a brief period is needed for the full beam strength to build up. Maximum brightness is attained in approx. 15 seconds.
The level control system for the rear axle maintains constant ground clearance of your vehicle, even when carrying a load.
The xenon lamps light up the side and front areas of the vehicle with significantly more brightness and uniformity then the traditional halogen lamps.
