Everything under control

Tachometer

Red warning lamp

The engine is overheated. Reduce your speed immediately and pull over at a suitable location. Switch off the engine and allow it to cool down. Contact your nearest BMW Center or a workshop that works according to BMW repair procedures with correspondingly trained personnel. Do not open the hood, otherwise there is a risk of injury from scalding.< The orange warning zone between arrows 1 and 2 shows the currently permissible engine speed, which depends on engine temperature. As engine temperature increases, some of the LEDs in this warning zone go out one after another. As much as possible, avoid driving at engine speeds within the illuminated warning zone. Never force the engine speed up into the red warning zone beginning at arrow 2. To protect the engine, the fuel supply is interrupted when speed reaches this sector.

Yellow warning lamp

The engine is too warm. Continue driving, but in a moderate manner, so that the engine can cool down. If the warning lamp comes on again, have the engine checked without delay.

Engine oil thermometer

Fuel gauge

Reserve

In contrast to the descriptions in the Owner's Manual for the BMW Z4, the reserve level for the BMW Z4 M Roadster/Z4 M Coupe is approx. 2.6 US gallons/10 liters. The general operating temperature lies between 1757/806 and 2507/1206. Do not exceed the maximum temperature of 3007/1506. If the engine oil temperature is too high, the permissible engine speed, and thus the available engine output, is reduced.

Coolant temperature

In contrast to the descriptions in the Owner's Manual for the BMW Z4, your BMW Z4 M Roadster/Z4 M Coupe is not equipped with a coolant thermometer. Should the coolant and thus the engine become too hot, a warning lamp will come on in the instrument cluster.

Service interval display

Regardless of your service requirements, have the breaking-in inspection per-
formed by your BMW Center after driving 1,200 miles/2,000 km.<
Technology for driving comfort and safety
Driving stability control systems
In contrast to the descriptions in the Owner's Manual for the BMW Z4, your BMW Z4 M Roadster/Z4 M Coupe does not feature Dynamic Traction Control DTC.

Activating DSC

Press the button briefly; the indicator lamp goes out in the instrument cluster.

Checking

The indicator lamp flashes: DSC controls the drive forces and brake forces. The indicator lamp is lit: DSC is deactivated.
Dynamic Stability Control DSC
DSC prevents slip at the drive wheels while starting off and accelerating the vehicle. DSC also recognizes unstable vehicle conditions, such as fishtailing or nose-diving. In these cases, and subject to physical limits, DSC helps to keep the vehicle on a steady course by reducing engine speed and by applying brakes at individual wheels. The laws of physics cannot be repealed even with DSC. It will always be the driver's responsibility to drive in a manner that matches road conditions. Therefore, do not limit the additional safety margin by practicing risky driving.<

Flat Tire Monitor FTM

In contrast to the descriptions in the Owner's Manual for the BMW Z4, your BMW Z4 M Roadster/Z4 M Coupe is not equipped with Run Flat tires. You should therefore observe the following when you receive a flat tire warning.

Flat tire warning

The warning lamp in the instrument cluster lights up in red. A signal also sounds. There is a flat tire or substantial loss of tire pressure. 1. Reduce speed and pull the vehicle over carefully. Avoid strong braking and steering maneuvers. 2. Determine which tire is damaged. To do this, check the tire inflation pressure using the M Mobility System, refer to Restoring tire inflation pressure on page 33. 3. Use the M Mobility System to repair the flat tire, refer to page 31.

Deactivating DSC

Press the button; the DSC indicator lamp in the instrument cluster lights up. No more interventions to increase stability and forward momentum are carried out. To enhance vehicle stability, reactivate DSC as soon as possible.

Power steering

In contrast to the descriptions in the Owner's Manual for the BMW Z4, your BMW Z4 M Roadster/Z4 M Coupe is equipped with hydraulic power steering.
This section provides you with information useful in dealing with specific driving and operating conditions.
Special operating instructions

Break-in procedures

In contrast to the descriptions in the Owner's Manual for the BMW Z4, please take note of the following differences for your BMW Z4 M Roadster/Z4 M Coupe. Always obey all official speed limits.

Driving notes

Ground clearance
The front spoiler greatly restricts the vehicle's ground clearance. Make sure that your BMW always has sufficient ground clearance, e.g. when entering underground garage complexes or driving over the edge of a curb; otherwise the front spoiler could be damaged.<
Engine and differential Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do not exceed 5,500 rpm or 100 mph/170 km/h. Strictly avoid depressing the accelerator pedal to full-throttle position. After the breaking-in inspection at 1,200 miles/ 2,000 km, engine or road speeds can be gradually increased.

Braking safely

In contrast to the descriptions in the Owner's Manual for the BMW Z4, your BMW Z4 M Roadster/Z4 M Coupe is equipped with perforated brake discs. In certain braking situations, operation of the perforated brake discs can cause noise; however, this does not affect the performance and operating safety of the brakes.

Transmission

The function of the transmission reaches its optimal level only after driving a distance of approx. 300 miles/500 km. Do not exceed engine speeds of 5,500 rpm during this time.
After replacing components
The same break-in procedures should be observed if any of the components mentioned above have to be renewed in the course of the vehicle's operating life.
This section helps you maintain your car's mobility by supplying important information on vital topics including fuels and lubricants, wheels and tires, service, maintenance and breakdown assistance.

Refueling

Note when refueling
In contrast to the descriptions in the Owner's Manual for the BMW Z4, please take note of the following differences for your BMW Z4 M Roadster/Z4 M Coupe.

Fuel tank capacity

Approx. 14.5 US gallons/55 liters, including the reserve capacity of approx. 2.6 US gallons/ 10 liters. Do not drive until the tank is empty. Otherwise, the engine may not operate properly and damage could result.<

Fuel specifications

Do not fill the tank with leaded fuel, as this would cause permanent damage to the catalytic converter.<
Required fuel Super Premium Gasoline/AKI 91
This gasoline is highly recommended. However, you may also use gasoline with less AKI. The minimum AKI Rating is 89. Do not fill the tank with any gasoline below the specified minimum fuel grade; otherwise engine damage could result.<

Wheels and tires

In contrast to the descriptions in the Owner's Manual for the BMW Z4, your BMW Z4 M Roadster/Z4 M Coupe is not equipped with Run Flat tires. The factory-approved radial-ply tires are specifically matched to your vehicle and offer optimal road safety as well as enhanced driving comfort if used properly. In the event of a flat tire, proceed as described under M Mobility System, refer to page 31. At a glance Reference Mobility Driving tips 32/220 38/260 Controls 30/210 33/230 32/220 36/250
Pressure specifications in psi/kPa

Correct wheels and tires

Information for your safety
Z4 M Roadster: tire inflation pressures

Do not add oil until the oil level has dropped almost to the lower mark on the dipstick, refer to Checking the oil level. Do not add oil beyond the upper mark on the dipstick, otherwise excessive oil can lead to engine damage.< Before you check the engine oil level after adding oil, restart the engine and let it run to obtain a correct reading. Then proceed as described under Checking the oil level. BMW engines are designed to operate without oil additives; the use of additives could even lead to damage in some cases. The same applies to the transmission and differential as well as to the power steering.< Continuous exposure to used oil has caused cancer in laboratory tests. For this reason, thoroughly wash any areas of skin that have come into contact with oil using soap and water. Keep oils, greases, etc. out of the reach of children and comply with the warnings on the containers. Otherwise, health hazards may result.< Comply with the applicable environmental regulations concerning the disposal of used oil.< Recommendation: have the oil changed at your BMW Center.
The oil volume between the two marks on the dipstick corresponds to approx. 1.4 US quarts/ 1.3 liters.

Approved engine oils

The quality of the engine oil is extremely important for the function and life of an engine. BMW only approves specific oils after confirming their suitability for use in its vehicles with extensive testing.
The warning lamp lights up in yellow after the engine is switched off. A signal also sounds. Check the engine oil level using dipstick 7 at the earliest opportunity, e.g. when you stop to refuel, and refill engine oil.

Adding engine oil

Only use oils specifically approved for your vehicle model. Your BMW Center will be glad to advise you about oils currently approved for your vehicle.< You can also call BMW of North America tollfree at 1-800-831-1117 or visit this website: www.bmwusa.com to obtain this information. Do not use any oil additives, as they could cause engine damage under some circumstances.<

Alternative oil grades

If a high-performance synthetic oil approved by BMW should be unavailable, you may use small volumes of other oils for topping up between oil changes. The following data must appear on the packaging: > Viscosity preferred: SAE 10W-60 alternative: SAE 5W-40 or SAE 10W-40 > Specification preferred: API SJ/CF alternative: API SJ, also SK, SL, S.

Low ambient temperatures

The oils used by BMW at the factory for your vehicle model can be used at virtually all ambient temperatures. However, if the vehicle is operated for a longer period at temperatures below 47/206, your BMW Center will be glad to recommend a suitable oil.

Replacing components

The onboard tool kit can be found on the righthand side of the cargo bay in a compartment next to the battery cover.

M Mobility System

Repairing a flat tire
To repair a flat tire, an M Mobility System is provided in your BMW Z4 M Roadster/Z4 M Coupe. Using this system you can apply a sealant to the inside of the tire, seal off the damaged area, restore the tire inflation pressure and then continue driving. Safety measures in the event of a flat: Park the vehicle as far as possible from passing traffic and on solid ground. Switch on the hazard warning flashers. Lock the steering wheel so that the wheels are facing straight ahead. Apply the handbrake and engage first or reverse gear. Have all vehicle occupants get out of the vehicle and ensure that they remain outside the immediate area in a safe place, such as behind a guardrail. If a warning triangle or portable hazard warning lamp is required, set it up on the roadside at an appropriate distance from the rear of the vehicle. Comply with all national safety guidelines and regulations.<

To repair a flat tire with the M Mobility System, proceed as follows: > Fill sealant into wheel > Distribute sealant > Restore tire inflation pressure
Immediately drive approx. 2 miles/3 km so that the sealant is evenly distributed in the tire. Do not exceed a speed of 35 mph or 60 km/h. Do not drive slower than 12 mph or 20 km/h if possible.<
Filling sealant into wheel
Strictly adhere to the specified order, otherwise highly pressurized sealant could escape.< 1. Shake sealant bottle. 2. Screw hose 9 onto connection of sealant bottle. 3. Unscrew and remove dust cap from valve of defective wheel and screw filler hose 2 of sealant bottle onto valve. 4. Insert sealant bottle on compressor housing so that the bottle is in an upright position.
Restoring tire inflation pressure
1. After approx. 2 miles/3 km, pull over at a suitable location. 2. Screw compressor hose 9 directly onto tire valve. 3. Insert connector 3 into cigarette lighter socket inside the vehicle. 4. Correct tire inflation pressure to 29 psi/ 200 kPa. With the ignition switched on: > To increase inflation pressure: switch on the compressor, position I. Switch off the device briefly to check the tire's current inflation pressure. Driving tips Reference Mobility Do not allow the compressor to run for more than 10 minutes, otherwise the device will overheat and may be damaged.< > To reduce inflation pressure: press button 8. if the inflation pressure is not maintained, drive the vehicle again, refer to Distributing sealant. Then repeat steps 1 to 4 once. Using the M Mobility System can be ineffective with tire punctures larger than approx. 1/6 in/ 4 mm. Please contact the nearest BMW Center or a workshop that works according to BMW repair procedures with correspondingly trained personnel if the tire cannot be made ready for driving with the M Mobility System.< The tire inflation pressure must be at least 29 psi/200 kPa. Otherwise do not continue driving.<
