Traction Control System (TCS)

Read and observe
on page 138 first.
TCS prevents the spinning of the wheels of the driven axle. 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

Activating/deactivating TCS
The activation or deactivation of TCS can be done, depending on equipment, in
one of the following ways.

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.
Note
On vehicles without the ESC system, the warning light
upon deactivation of the ASR system, but a message is only displayed on the
display of the instrument cluster.
Electronic Differential Lock (EDL and XDS)
Read and observe
on page 138 first.
EDL
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. The vehicle can continue to be driven and
has the same characteristics as a vehicle not fitted with EDL. Once the brakes
have cooled down, there is an automatic re-activation of EDL.
XDS
XDL is an extension to the electronic differential lock. XDL does not respond to
traction, but to the load relief of the inner front wheel of the driving axle dur-
ing fast cornering.
The automatic brake intervention on the brake of the wheel with reduced load
prevents the wheel from spinning. Thus, the traction is improved and the vehi-
cle can continue to follow the desired track.
Driver Steering Recommendation (DSR)
Read and observe
on page 138 first.
The DSR indicates to the driver in critical situations a steering recommenda-
tion in order to stabilise the vehicle. The DSR is activated, for example, on the
right and left vehicle side when braking sharply on different road surfaces.
