- Electromechanical Parking Brake Indicator Lamp --
- Component location in Instrument Cluster Control Module -J285-.
- lights up when the parking brake is engaged and the ignition is switched on,
- lights up for approximately 30 seconds when the parking brake is engaged and the ignition is switched off
- blinks after engaging the parking brake if the brake pressure is not sufficient to prevent the vehicle from rolling.NOTE:
The indicator light must go out when the parking brake is released.
- Brake System Indicator Lamp --
- Component location in Instrument Cluster Control Module -J285-.
- Turns on with the ABS indicator lamp when the ABS system malfunctions
- blinks when the brake fluid is too low
- Blinks when there is a malfunction in the brake system
The malfunction is indicated more precisely when the "SET button" in the instrument cluster is pressed.
- ABS Indicator Lamp -K47-
The indicator lamp monitors the ABS and the Electronic Differential Lock (EDL).
- Component location in Instrument Cluster Control Module -J285-.
- lights up for several seconds when ignition is switched on and goes out after an automatic ABS system self-check if there are no malfunctions in the ABS system.
- There is an ABS malfunction if the indicator light:
- does not light up when ignition is switched on,
- does not go out after a few seconds,
- lights up while driving.
- The vehicle can be stopped with the standard brake system. However, a change in braking behavior should be checked.
The Electronic Differential Lock (EDL) and ABS work together. The ABS indicator light lights up when the EDL malfunctions.
- ASR/ESP Indicator Lamp -K155-
- Component location in Instrument Cluster Control Module -J285-.
- blinks when driving if ESP/ASR engages regularly.
- comes on when ignition is switched on and goes out after a short self-check.
- comes on if there is an ESP system malfunction.
- comes on if there is an ABS system malfunction because ESP and ABS work together.
- comes on when ESP/ASR is switched off.
- comes on during sensor programming if:
- the battery was disconnected and connected,
- vehicle was started with jump start,
- the battery is too weak.
- after the sensor programming procedure, the ESP light goes out after driving a short distance.
