Electronic stability programme (ESP)*
General
General
The ESP aids you maintain control of your vehicle in situations in border-
line driving situations such as when negotiating a curve too fast. The risk
of skidding is reduced and your car thus offers greater driving stability
depending on the conditions of the road surface. This occurs at all speeds.
The following systems are integrated into the electronic stability
programme:
•Electronic Differential Lock (EDL),
•Traction control system (TCS),
•Antilock brake system (ABS),
•Brake Assist.
Operating principle
The ESP switches on automatically when the engine is started and then
conducts a self-test. The ESP control unit processes data from the indi-
vidual systems. It also processes additional measurement data which are
supplied by highly sensitive sensors: the rotational velocity of the vehicle
about its vertical axis, the lateral acceleration of the vehicle, the braking
pressure and the steering angle.
The direction which the driver wishes to take is determined based on the
steering angle and the speed of the vehicle and is constantly compared
with the actual behaviour of the vehicle. If differences exist, such as the
car beginning to skid, the ESP will automatically brake the appropriate
wheel.
The car is stabilised again by the forces which take effect when the wheel
is braked. Intervention into the brake system takes place primarily on the
outer front wheel of a vehicle which tends to oversteer (tendency for the
rear of the vehicle to break away) while occurs this is on the inner rear
wheel of a vehicle which tends to understeer (tendency to shift out of the
curve). This braking control cycle is accompanied by noises.
The ESP operates in combination with the ABS ⇒page 181, “Antilock
brake system (ABS)*”. If there is a fault in the ABS system, the ESP also
does not operate.

The ESP warning light ⇒page 35 lights up in the instrument cluster when
there is a fault on the ESP.
Switching off
You can switch the ESP off and on again as you wish, by pressing the
button ⇒page 177, fig. 145 . The ESP warning light ⇒page 35 lights up
in the instrument cluster when the ESP is switched off.
The ESP should normally always 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 E SP 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. Differing 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 232, “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,
accelerate and climb a steep hill when the conditions of the road surface
are unfavourable.
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 trans-

mitted to the road surface is automatically adapted by reducing the engine
speed. This occurs at all speeds.
The TCS operates in combination with the ABS
⇒page 181, “Antilock
brake system (ABS)*”. The TCS will not f unction if a fault exists in the ABS
system.
The TCS warning light ⇒page 34 lights up in the instrument cluster when
there is a fault on the TCS.
Switching off
You can switch the TCS off and on again as you wish by pressing the
button ⇒page 178, fig. 146 . The TCS warning light ⇒page 34 lights up
in the instrument cluster when the TCS is switched off.
The TCS should normally always 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 TCS again.
WARNING
You should always adjust your style of driving to the conditions of
the road surface and the traffic situation. 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 TCS. Differing rolling circumferences of the
tyres can lead to an undesirable reduction in the engine output.

assignment of tyres and wheels) can influence the function of the TCS
⇒ page 232, “Accessories, changes and replacement of parts”.
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,
accelerate and climb a steep hill when the conditions of the road surface
are unfavourable.
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 difference 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 accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unusually severe stresses exist in
order to avoid excessive heat generation in the disc brake on the wheel

•The increased safety offered by the Brake Assist must not tempt
you to take a greater safety risk than otherwise.
Power steering*
The power steering enables you to steer the vehicle with less physical
force.
The steering characteristics can be changed by a specialist garage.
You will place great stresses on the power steering system if the steering
is turned to full lock when the vehicle is stationary. Turning the steering to
full lock in such a situation will be accompanied by noises.
It is still possible to fully steer the vehicle if the power steering fails or if the
engine is not running (vehicle being towed in). The only difference is that
greater physical effort is required.
It is possible that the hydraulic pump of the power steering will not run due
to the low vehicle network voltage if the battery has gone flat and the
engine must started with the help off jump leads. This condition will be
indicated by lighting up of the warning light.
The power steering operates again if the battery is charged to a specific
range when engine is running. It also operates again, if the engine can be
started with its own battery.
Caution
Do not leave the steering at full lock for more than 15 seconds when the
engine is running - risk of damaging the power steering!
Note
Have the steering inspected as soon as possible by a specialist garage if
there is a leak or fault in the system.
Tyre inflation pressure-control system*
The tyre inflation pressure-control system compares with the aid of the
ABS sensors the speed and also the roll ing circumference of the individual
wheels. If the inflation pressure and therefore the rolling circumference of
a wheel has changed significantly, the warning light
 lights up in the
dash panel ⇒page 34. The tyre inflation pressure-control system func-
tions late or too sensitively if:
•the structure of the tyre is damaged,
•the vehicle is loaded to one side or with a load on the roof,
