In vehicles with front wheel traction, the TCS lowers the engine
power to stop the wheel spinning when you accelerate. This feature
works at any speed in combination with the ABS. If there is an ABS
breakdown, the TCS stops working.
Vehicles fitted with TCS are also fitted with an electronic differential
lock (EDL).
The EDL makes it much easier, or even possible, to pull away,
accelerate and climb steep gradiants in unfavourable conditions.
The EDL works fully automatically – the driver does not need to do
anything at all.
It uses the ABS sensors to monitor the speed of the driving wheels.
Up to a speed of about 80 km/h (50 mph), a difference in speed of
the drive wheels of approximately 100 rpm caused by a slippery
road surface on o o n n e e s s i i d d e e is balanced out by slowing down the
wheel which is slipping and thereby applying more driving force to
the other drive wheel through the differential.

To ensure that the brake disc of the braked wheel does not
overheat, the EDL will automatically switch itself off if excessive
demands are placed on it. The vehicle remains operational and has
the same characteristics as a vehicle without EDL. For this reason,
the switching off of the EDL is not noticed.
As soon as the brakes have cooled off, the EDL will switch itself
back on again.
If the ABS warning lamp lights up there may be a fault present in
the EDL. Take the vehicle to a Technical Service Centre as soon as
possible!

The TCS connects automatically once the engine is started. If
necessary, it can be connected or disconnected by pressing shortly
the button located on the central console.
When the TCS is switched off a pilot light comes on.
You should normally always have the TCS on. Only in exceptional
circumstances when you want the wheels to spin should you
switch it off. For instance:
– When you are using snow chains.
– When driving in deep snow or on a soft surface.
– When the car is stuck, to "rock" it out, and
