292

General information: If a bulb in the instrument cluster fails to come on during the bulb self-check when

Possible cause The ABS has detected a malfunction and has switched off. The BAS and the ESP are also switched off (see messages in display). The brake system is still functioning nor- mally but without the ABS available. If the ABS control unit is malfunctioning, other systems such as Parktronic*, Distron- ic*, and the automatic transmission may also be malfunctioning. The charging voltage has fallen below 10 volts and the ABS has switched off.

the ignition is turned on, have it checked and replaced if necessary.

Suggested solution 왘 Continue driving with added caution. Wheels may lock during hard braking, reducing steering capability.

왘 Have the system checked at an autho- rized Mercedes-Benz Center as soon as possible.

Failure to follow these instructions increas- es the risk of an accident.

When the voltage is above this value again, the ABS is operational again. 왘 If necessary, have the generator and

battery checked.

Practical hints What to do if …?

Possible cause You are driving with the parking brake set. 왘 Release the parking brake (컄 page 47).

Suggested solution

There is insufficient brake fluid in the reser- voir.

왘 Risk of accident! Carefully stop the vehi-

cle and notify an authorized Mercedes-Benz Center. Do not add brake fluid! This will not solve the prob- lem.

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.

Problem (USA only) (Canada only)

The red brake warning lamp comes on while driving and you hear a warning sound. The red brake warning lamp comes on while driving.

Warning!

Driving with the brake warning lamp illumi- nated can result in an accident. Have your brake system checked immediately if the brake warning lamp stays on.

Problem (USA only) ± (Canada only)

The yellow malfunction indicator lamp comes on while driving.

Possible cause There is a malfunction in: 앫 The fuel management system 앫 The ignition system 앫 The emission control system 앫 Systems which affect emissions Such malfunctions may result in excessive emissions values and may switch the en- gine to its limp-home (emergency opera- tion) mode. The fuel cap is not closed tightly. Your gas tank is empty.

l The red Distronic warn- ing lamp comes on while driving.

You are too close to the vehicle in front of you to maintain selected speed.

294

Suggested solution 왘 Have the vehicle checked as soon as

possible by an authorized Mercedes-Benz Center. An on-board diagnostic connector is used by the service station to link the vehicle to the shop diagnostics system. It allows the accurate identification of system malfunctions through the read- out of diagnostic trouble codes. It is lo- cated in the front left area of the footwell next to the parking brake pedal.

왘 Check the fuel cap (컄 page 257). 왘 After refuelling start the engine three or

four times in succession.

The limp-home mode is canceled. You do not need to have your vehicle checked. 왘 Apply the brakes immediately to in-

crease the following distance.

Problem l The red distance indicator lamp comes on while driving and you hear a warning sound.

v The yellow ESP warning lamp

comes on while driving.

v The yellow ESP warning lamp

flashes while driving.

Possible cause 앫 You are gaining too rapidly on the vehi-

cle ahead of you.

앫 The distance warning system has recog-

nized a stationary obstacle on your probable line of travel.

The ESP is deactivated. Risk of accident! Adapt your speed and driving to the prevail- ing road, weather and traffic conditions. The ESP or traction control has come into operation because of detected traction loss in at least one tire. Distronic* is deactivated.

Practical hints What to do if …?

Suggested solution 왘 Apply the brakes immediately. 왘 Carefully observe the traffic situation. You may need to brake or maneuver to avoid hitting an obstacle.

왘 Switch the ESP back on (컄 page 81). If the ESP cannot be switched back on, have the system checked at an authorized Mercedes-Benz Center as soon as possible.

왘 When driving off, apply as little throttle

as possible.

왘 While driving, ease up on the accelera-

tor.

왘 Adapt your speed and driving to the pre-

vailing road, weather conditions.

왘 Do not deactivate the ESP.

Exceptions: (컄 page 80).

Failure to follow these instructions increas- es the risk of an accident.

Problem

The yellow fuel tank reserve warning lamp comes on while driving.

< The red seat belt telltale illumi- nates briefly after starting the engine.

Possible cause The fuel level has dropped below the re- serve mark.

Suggested solution 왘 Refuel at the next gas station

(컄 page 257).

The warning lamp reminds you to fasten seat belts.

왘 Fasten your seat belt.

The warning lamp goes out.

H The yellow warning lamp for the tire pressure monitor comes on.

The tire pressure monitor detects a loss of pressure in at least one tire.

Warning!

When the tire pressure monitoring system warning lamp is lit, one or more of your tires is significantly under-inflated. You should stop and check your tires as soon as possi- ble, and inflate them to the proper pressure as indicated on the vehicle’s tire information placard.

Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. Each tire, including the spare, should be checked monthly when cold and set to the recommended inflation pressure as speci- fied in the vehicle placard and owner’s manual.

296

왘 Bring the vehicle to a halt, avoiding

abrupt steering and braking maneuvers. Observe the traffic situation around you. 왘 Take note of the messages in the multi-

function display.

The recommended tire inflation pres- sure for your vehicle can be found on the inside of the fuel filler flap, not in the owner’s manual.

Practical hints What to do if …?

Suggested solution 왘 Drive with added caution to the nearest

authorized Mercedes-Benz Center.
