Level Control System Indicator Lamps

Warning Lamps









Brake Pad Wear Indicator Lamp (K32 )

• If the brake pad wear indicator lamp - 2 - does not switch off 3 seconds after the ignition is switched on or if it lights up when the vehicle is driven, it could be caused by the following malfunctions:

- a - Brake pads may be worn.

Check front and rear axle brake pads. Replace worn brake pads.

- b - There is a wiring malfunction. Refer to

ABS Warning Lamp (K47)

• If the ABS warning lamp - 3 - does not go out after the ignition is switched on and the test sequence is complete, it could be caused by the following errors:

- a - Voltage supply is under 10 volts.

- b - There is an ABS malfunction.

CAUTION!
The ABS system remains switched off during an ABS malfunction - b -, but the traditional brake system remains fully functional.

- c - There was a periodic wheel speed sensor malfunction since the last vehicle start.

If this is the case, the ABS warning lamp will go out automatically after the vehicle is started again and a speed of 20 km/h has been exceeded.

- d - The connection from the instrument cluster to the ABS control module is interrupted. Refer to

- e - The instrument cluster is faulty.

ABS Warning Lamp (K47) and Brake System Warning Lamp (K118)

• If the ABS warning lamp - 3 - goes out but the brake system warning lamp - 4 - lights up, the malfunctions causes may be:

- a - Parking brake is engaged.

- b - Brake fluid level is too low (warning lamp blinks).

Three warning tones are audible after switching on the ignition.

- c - There is a malfunction in the wiring to the brake system warning lamp. Refer to

• If the ABS warning lamp - 3 - and the brake system warning lamp - 4 - light up, the ABS system is malfunctioning. A change in braking behavior should be checked.

CAUTION!
After the ABS warning lamp and the brake system warning lamp light up, rear wheels may lock prematurely when braking.

Traction Control Indicator Lamp (K86 )

• If the traction control indicator lamp - 1 - does not go out after the ignition is switched on and the test sequence is complete, malfunction causes may be:

There is a malfunction present which only affects the ASR. The ABS and Electronic Brake-pressure Distribution (EBD) safety systems are still completely functional => check the Diagnostic Trouble Code (DTC) memory.

- a - Short to positive (+) in the ASR/ESP button.

- b - A malfunction in the activation of the traction control indicator lamp. Refer to

- c - ASR system was switched off using the ASR/ESP button.

If the traction control indicator lamp blinks while driving, ASR system is operating in regulated mode.

- a - Short circuit to B+ in the ASR/ESP button.

- b - A malfunction in the actuation of the ASR/ESP control lamp.

- c - ASR/ESP system was switched off using the ASR/ESP button.

If the ASR/ESP control lamp flashes while driving, the ASR or ESP systems are regulating the system.

• If the ASR/ESP control lamp - 1 - did not light up during the self test, the following malfunction is present:

- a - The ASR/ESP control lamp is defective => Perform electrical test.
