Warning lamps
The brake system uses three warning lamps positioned in the combined instrument panel.
ABS warning lamp
The ABS warning lamp indicates an ABS system fault.
When the ignition is switched on, the ABS control module check the function of the ABS warning lamp. The lamp lights for up to 5 seconds. The ABS control module continuously monitors the system voltage. If the voltage increases or decreases beyond certain parameters the ABS warning lamp lights up and the system goes into standby mode. The lamp goes out when the correct operating system voltage is returned. No diagnostic trouble codes (DTCs) are stored for defective voltage.
Brake warning lamp
The brake warning lamp indicates:
- faults in the electronic brake force distribution (EBD) function
- that the brake fluid level is too low.
Traction control warning lamp (only cars with STC/DSTC)
The traction control warning lamp is on continuously when:
- STC/DSTC is deactivated because a diagnostic trouble code (DTC) is stored
- STC/DSTC is manually switched off
- the brake disc temperature is too high.
The traction control warning lamp flashes when:
- a drive wheel starts to spin during acceleration. The control module is activated to regain traction
- the lateral stability limit is exceeded (the car oversteers or understeers) during active yaw control.
