The brake system uses five warning lamps and a text display in the driver information module (DIM).

ABS warning lamp (1) 

The ABS warning lamp indicates a fault in the ABS system.

Brake warning lamp (2) 

The brake warning lamp indicates:

  • A fault in the electronic brake force distribution (EBD) function
  • That the brake fluid level is too low (the signal is transmitted from the central electronic module (CEM) to the driver information module (DIM)).

General warning lamp (3) 

Normally the general warning lamp lights together with the brake warning lamp.

Traction control warning lamp (4) 

The traction control warning lamp flashes:

  • When a drive wheel starts to spin during acceleration. Traction control is then activated to regain traction
  • When a drive wheel starts to spin on a slippery surface. Stability control is then activated to regain traction
  • When the lateral stability limit is exceeded (the car oversteers or understeers) during active yaw control.

Information lamp (5) 

The information light comes on when:

  • There is a fault with ABS, STC, DSTC or TRACS
  • The brake disc temperature is too high.

Text display in the combined instrument panel 

Displays information about faults in the brake system or other settings.

NOTE:

The text may vary depending on the model year and equipment. It may also change as a result of software updates in the driver information module (DIM).
