Anti-blocking system (ABS)
Read and observe
on page 219 first.
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.
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 219 first.
The MSR prevents the blocking tendency of the drive wheels when shifting
down or with an abrupt deceleration (e.g. on icy or otherwise slippery road
surfaces).
If the drive wheels lock, the engine speed is automatically increased. This re-
duces the braking effect of the engine, and the wheels can rotate freely again.
Traction control (ASR)
Read and observe
on page 219 first.
The ASR prevents spinning of the drive wheels. TCS reduces the drive power
transmitted to the wheels in the case of slipping wheels. Thus, for example,
driving on road surfaces with low grip is made easier.
During a TCS intervention, the indicator light

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 it is necessary to "rock" a car free when it has become stuck.

Electronic Differential Lock (EDL and XDS)
Read and observe
on page 219 first.
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes the spinning wheel, if necessary, and transmits the driving force to the
other driving wheel. Driving becomes easier on road surfaces with different
traction under each wheel of the driven axle.
EDL switches off automatically to avoid excessive heat generation on the
brake of the wheel being braked. Once the brakes have cooled down, there is
an automatic re-activation of EDL.
XDS is an extension to the electronic differential lock (EDL). XDS does not re-
spond to the relieved inner curve wheel of the driven axle in the case of fast
cornering.
By applying braking force to the relieved wheel, spinning is prevented by the
XDS. This has a positive effect on the driving stability and steerability of the
vehicle.
Active steering assist (DSR)
Read and observe
on page 219 first.
In critical situations, the DSR provides the driver with a steering recommenda-
tion in order to stabilise the vehicle. DSR is activated, for example, on the right
and left vehicle side when braking sharply on different road surfaces.
