TCS reduces engine power to help prevent the drive wheels of front-
wheel drive vehicles losing traction during acceleration. The system
works in the entire speed range in conjunction with ABS. If a
malfunction should occur in the ABS, the TCS will also be out of
action.
TCS helps the vehicle to start moving, accelerate and climb a
gradient in slippery conditions where this may otherwise be
difficult or even impossible.
The TCS is switched on automatically when the engine is started. If
necessary, it may be turned on or off by briefly pushing the button
on the centre console.
When the TCS is off, the warning lamp is lit.
The TCS should normally be left switched on at all times. Only in
exceptional circumstances, when slipping of the wheels is
required, should it be disconnected, for example:
– With compact temporary spare wheel.
– When using the snow chains
– When driving in deep snow or on loose surfaces
– When the vehicle is bogged-down, to free it by rocking it.
The TCS should be switched on again afterwards as soon as
possible.N No

e• In order to ensure that TCS function correctly, all four wheels must be
fitted with the same tyres. Any differences in the rolling radiusof the tyres
can cause the system to reduce engine power when this is not desired.
• Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the
efficiency of the ABS and TCS.

ESP reduces the danger of skidding by braking the wheels
individually.

calculate the changes of direction desired by the driver, and

constantly compares them with the actual behaviour of the vehicle.
If the desired course is not being maintained (for instance, if the
car is starting to skid), then the ESP compensates automatically by
braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a
stable condition. If the vehicle tends to oversteer, the system will
act on the front wheel on the outside of the turn.

•In order to ensure that ESP functions correctly, all four wheels must be

Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during
braking
⇒chapter “Anti-lock brake system and traction control
ABS”.
K
Electronic differential lock (EDL)
The electronic differential lock helps prevent the loss of traction
caused if one of the driven wheels starts spinning.
EDL helps the vehicle to start moving, accelerate and climb a
gradient in slippery conditions where this may otherwise be
difficult or even impossible.
It uses the ABS sensors to monitor the speed of the driven wheels.
In case of an EDL fault the warning light for ABS lights up
⇒
chapter “Warning lamps”.
At speeds of up to approximately 80 km/h, it is able to balance out
differences in the speed of the driven wheels of approximately 100
rpm caused by a slippery road surface on one side of the vehicle. It
does this by braking the wheel which has lost traction and
distributing more driving force to the other driven wheel via the
differential.
To prevent the disc brake of the braked wheel from overheating,
the EDL cuts out automatically if subjected to excessive loads. The
vehicle will continue to function normally without EDL. For this
reason, the driver is not informed that the EDL has been switched
off.
The EDL will switch on again automatically when the brake has
cooled down.
