•If the brake warning lamp H should light up together with the ABS
warning lamp J, stop the vehicle immediately and check the brake fluid
level in the reservoir Ÿpage 221. If the fluid level has dropped below the
“MIN” mark you must not drive on. Risk of accident. You should obtain
professional assistance.
•If the brake fluid level is correct, the fault in the brake system may have
been caused by a failure of the ABS control function. This could cause the
rear wheels to lock quickly when you brake. This could cause the tail of the
vehicle to skid sideways. Drive carefully to the nearest qualified workshop
and have the fault corrected.
Electronic differential lock (EDL)
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.
The electronic differential lock (EDL) only works when the engine is running.
EDL helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.
It uses the ABS sensors to monitor the speed of the driven wheels.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences 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 car remains operational
and will behave in the same way as a car 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.
WARNING
Try to always adapt the speed of the vehicle to weather, road and traffic
conditions. Do not let the extra safety afforded by the system tempt you
into taking any risks when driving. Risk of accident.
•When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may other-
wise start to spin. This could impair the car's stability.
•Always adapt your driving style to suit road conditions and the traffic
situation.
WARNING
Modifications to the vehicle or work carried out incorrectly (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, EDL, ESP and TCS
and lessen their efficiency.
Electronic stabilisation programme (ESP)
The electronic stabilisation programme helps to reduce the
danger of skidding.
The electronic stabilisation programme (ESP) consists of ABS, EDL and TCS
and only works when the engine is running.
The ESP should generally be left switched on at all times. Only when the
necessary drive can not be obtained should the ESP be disconnected.
For example:
•when driving with snow chains,
