Braking and stabilisation systems
Introduction
The brake and stabilization systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.
The error display is in Chapter » page 41, Warning lights.
WARNING
Please take note of the general points relating to the use of assistance sys-
tems » page 213, in section Introduction.
Stability Control (ESC)
Read and observe on page 214 first.
ESC improves vehicle stability in critical driving situations (e.g. if the vehicle
starts to skid) by the braking the individual wheels to maintain the direction.
During an ECS intervention, the warning light flashes in the instrument clus-
ter.
ESC Sport
Read and observe on page 214 first.
ESC Sport allows for a sportier driving style. With ESC Sport activated, no
ESC intervention takes place when the vehicle slightly oversteers and under-
steers, and ASR is so limited that the drive wheels can be spun.

ABS prevents the wheels locking when braking. Thus helping the driver to
maintain control of the vehicle.
The intervention of the ABS is noticeable from the pulsating movements of
the brake pedal which is accompanied by noises.
