Possible cause
Warning!
If the message Front passenger airbag deactivated remains on in the multifunc- tion display and/or the 75 indica- tor lamp remains illuminated even after performing the above corrective steps, do not have any passenger use the front pas- senger seat until the system has been re- paired.
Practical hints What to do if …
Possible solution Note that after performing the corrective steps, it may take up to 60 seconds for the message Front passen- ger airbag activated to appear. If the message Front passenger airbag deactivated remains on in the multifunction display and/or the 75 indicator lamp remains on even after per- forming the above corrective steps, have the system checked as soon as possible by an authorized Mercedes-Benz Center. Do not have any passenger use the front passenger seat until the system has been repaired.

Possible cause The battery has insufficient voltage.
Possible solution 왘 Turn off unnecessary electrical con-
sumers.
The battery is no longer charging. Possible causes: 앫 alternator malfunctioning 앫 broken poly-V-belt Do not forget that the brake system re- quires electrical energy and may be oper- ating with restricted capability. Considerably greater brake pedal force is required and the stopping distance is in- creased.
왘 Stop immediately and check the
poly-V-belt. If it is broken: 왘 Do not continue to drive. Otherwise the engine will overheat due to an in- operative water pump which may re- sult in damage to the engine. Notify an authorized Mercedes-Benz Center.

Display messages Brake fluid Visit workshop
Possible cause There is insufficient brake fluid in the reservoir.
Warning!
Driving while these messages are displayed can result in an accident. Have your brake system checked immediately.
If there is a malfunction in the SBC brake system, we recommend that the vehicle be transported with all wheels off the ground using flatbed or appropriate wheel lift/dolly equipment.
A tow bar must be used if circumstances do not permit the use of the recommended towing methods and the vehicle requires towing with all four wheels on the ground.
Towing the vehicle with all four wheels on the ground is only permissible for distances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h). For more infor- mation, refer to “Towing the vehicle” (컄 page 439). If the SBC brake system enters its emergen- cy operation mode, the driver must apply significantly greater brake pedal pressure and depress the pedal much further than normal to obtain braking effect. If neces- sary, apply full pressure to the brake pedal. Brakes may only be applied to the front wheels. Stopping distance is increased!
382
Possible solution 왘 Risk of accident! Stop the vehicle and notify an authorized Mercedes-Benz Center. Do not add brake fluid! This will not solve the problem.
Do not add brake fluid before checking the brake system. Overfilling the brake fluid res- ervoir can result in spilling brake fluid on hot engine parts and the brake fluid catching fire. You can be seriously burned.
If you find that the brake fluid in the brake fluid reservoir has fallen to the minimum mark or below, have the brake system checked for brake pad thickness and leaks.
Brake pad thickness must be visually inspected by a qualified technician at the intervals specified in the Maintenance Booklet.

Possible cause There may be a malfunction in the: 앫 fuel injection system 앫 ignition system 앫 exhaust system 앫 fuel system The coolant level is too low.
Warning!
Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts. You can be seriously burned.
Do not ignore the low engine coolant level warning. Extended driving with the message and symbol displayed may cause serious engine damage not covered by the Mercedes-Benz Limited Warranty.

Display messages Coolant Stop, engine off
Possible cause The coolant is too hot.
During severe operation conditions and stop-and-go city traffic, the coolant tem- perature may rise close to 248°F (120°C).
The engine should not be operated with the coolant temperature above 248°F (120°C). Doing so may cause serious damage which is not covered by the Mercedes-Benz Limited Warranty.
Warning!
Driving when your engine is badly overheat- ed can cause some fluids which may have leaked into the engine compartment to catch fire. You could be seriously burned.
Steam from an overheated engine can cause serious burns and can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it.
Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.

In the case of a flat tire, you may tempo- rarily use the spare wheel when observing the following restrictions: 앫 Do not exceed a vehicle speed of
50 mph (80 km/h).
앫 Drive to the nearest tire repair facility
to have the flat tire repaired or re- placed as appropriate.
앫 Do not operate vehicle with more than
one spare wheel mounted.
For more information, see “Spare wheel” (컄 page 457).

왔 Replacing SmartKey batteries If the batteries in the SmartKey are dis- charged, the vehicle can no longer be locked or unlocked. It is recommended to have the batteries replaced at an autho- rized Mercedes-Benz Center.
Warning!
Keep the batteries out of reach of children.
If a battery is swallowed, seek medical help immediately.
Batteries contain materials that can harm the environment if disposed of improperly. Recycling of batteries is the preferred method of disposal. Many states require sellers of batteries to accept old batteries for recycling.

Practical hints Replacing bulbs
If the headlamps or front fog lamps are fogged up on the inside as a result of high humidity, driving the vehicle a dis- tance with the lights on should clear up the fogging.
Substitute bulbs will be brought into use when lamps malfunction. Observe the messages in the multifunction dis- play (컄 page 392).
왔 Replacing bulbs Bulbs
Safe vehicle operation depends on proper exterior lighting and signaling. It is there- fore essential that all bulbs and lamp as- semblies are in good working order at all times. Correct headlamp adjustment is extremely important. Have headlamps checked and readjusted at regular intervals and when a bulb has been replaced. See your autho- rized Mercedes-Benz Center for headlamp adjustment.

Warning!
Bulbs and bulb sockets can be very hot. Al- low the lamp to cool down before changing a bulb.
Notes on bulb replacement 앫 Use only 12 volt bulbs of the same type
and with the specified watt rating.
앫 Switch lights off before changing a bulb
to prevent short circuits.
Keep bulbs out of reach of children.
앫 Always use a clean lint-free cloth when
handling bulbs.
앫 Your hands should be dry and free of oil
and grease.
앫 If the newly installed bulb does not light up, visit an authorized Mercedes-Benz Center.
Halogen lamps contain pressurized gas. A bulb can explode if you: 앫 touch or move it when hot 앫 drop the bulb 앫 scratch the bulb Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is dangerous to replace the bulb or repair the lamp and its components. We recommend that you have such work done by a qualified technician.
