If there is a TCS intervention, the warning light

Anti-lock brake system (ABS)
Read and observe
on page 174 first.
ABS prevents the wheels from locking when braking. Thereby, it helps 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.
When the ABS system is active, do not brake periodically or reduce the pres-
sure on the brake pedal.
Engine drag torque control (MSR)
Read and observe
on page 174 first.
MSR counteracts the tendency of the drive wheels to lock during downshifts
or sudden deceleration (e.g. on icy or an otherwise slippery road surface).
If the drive wheels should lock, then the engine speed is automatically in-
creased. This reduces the braking effect of the engine and the wheels can ro-
tate freely again.
Traction control (TCS)
Read and observe
on page 174 first.
The TCS prevents the drive wheels from spinning. TCS reduces the drive pow-
er transmitted to the wheels in the case of slipping wheels. Thereby, for exam-
ple, driving on road surfaces with low grip is made easier.

With activation, the warning light
sage is displayed in the instrument cluster.
The TCS should normally always be enabled. The system should be deactivated
only in the following situations, for example.
▶
When driving with snow chains.
When driving in deep snow or on a very loose surface.
▶
When "rocking a car free" when it has become stuck.
▶
Electronic Differential Lock (EDL)
Read and observe
on page 174 first.
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes a spinning wheel if required and transfers the drive power force to the
other drive wheel. Driving becomes easier on road surfaces with different
traction under each wheel of the driven axle.
The EDL switches off automatically in order to avoid excessive heat genera-
tion on the brake of the wheel being braked. Once the brakes have cooled
down, there is an automatic re-activation of EDL.
Brake Assist (HBA)
Read and observe
on page 174 first.
The HBA increases the braking effect and helps to reduce the braking dis-
tance.
