Switching off
You can switch the ESP off and on again as you wish, by pressing the button ⇒ page 165, fig. 133. The ESP warning light ⇒page 33 lights up in the instru- ment cluster when the ESP is switched off.
The ESP should normally al ways be switched on. It may be good practice in certain exceptional cases, such as when you wish to have wheel slip, to switch off the system.
Examples:
•when driving with snow chains,
•when driving in deep snow or on a loose surface,
•when it is necessary to rock a car free when it has become stuck.
then you should switch on the ESP again.
WARNING
It is also not possible for the ESP to overcome the physical limits of the vehicle. Even if a vehicle fitted with ESP you should still always adapt your style of driving to the condition of the road surface and the traffic situation. This particularly applies when driving on slippery and wet roads. The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•All four wheels must be fitted with the same tyres in order to achieve problem-free operation of the ESP. Differ ing rolling circumferences of the tyres can lead to an undesirable reduction in the engine output.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assignment of tyres and wheels) can influence the function of the ESP ⇒ page 220, “Accessories, changes and replacement of parts”.
Traction control system (TCS)*
The traction control system prevents the driven wheels from
spinning when accelerating.
General
The TCS makes it much easier, and sometimes at all possible, to start off, accel- erate and climb a steep hill when the co nditions of the road surface are unfa- vourable.
Operating principle
The TCS switches on automatically when the engine is started and then conducts a self-test. The system monitors the speeds of the driven wheels with the aid of the ABS sensors. If the wheels are spinning, the force transmitted to the road surface is automatically adap ted by reducing the engine speed. This occurs at all speeds.
The TCS operates in combination with the ABS ⇒page 169, “Antilock brake system (ABS)*”. The TCS will not function if a fault exists in the ABS system.

Electronic Differential Lock (EDL)*
The electronic differential lock prevents an individual wheel
from slipping.
Models fitted with ESP are equipped with electronic differential lock (EDL).
General
The EDL makes it much easier, and sometimes at all possible, to start off, accel- erate and climb a steep hill when the conditions of the road surface are unfa- vourable.
Operating principle
The EDL is activated automatically, that is without any action on the part of the driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors. Should only one drive wheel begin spinning on a slippery surface there will be an appreciable di fference in the speed of the driven wheels. The EDL function brakes the slipping wheel and the differential transmits a greater driving force to the other driven wheel. This control process is also accompa- nied by noises.
Overheating of the brakes
The EDL switches off automati cally if unusually severe stresses exist in order to avoid excessive heat generation in the disc brake on the wheel which is being braked. The vehicle can continue to be driven and has the same characteristics as a vehicle not fitted with EDL.
The EDL switches on again automatically as soon as the brake has cooled down.
WARNING
•Depress the accelerator carefully when accelerating on uniformly slippery road surfaces, such as ic e and snow. The driven wheels might still spin despite the EDL and affect the stability of the vehicle - risk of an accident!
