Do not continue driving
if the warning light does not go off although the fluid is
at the correct level and also the fuse of the fan is in proper order. Contact a spe-
cialist garage to obtain assistance.
Please refer to the following guidelines ⇒ page 193, Cooling system
.
The following text will be displayed in the information display: Check coolant! Owner's manual! WARNING
● If you must stop for technical reasons, then park the vehicle at a safe dis-
tance from the traffic and switch off the engine and switch on the hazard
warning light system ⇒ page 50.
● Take care when opening the coolant expansion bottle. If the engine is hot,
the cooling system is pressurized - risk of scalding! It is best to allow the en-
gine to cool down before removing the cap.
● Do not touch the coolant fan The coolant fan may switch on automatically
even if the ignition is off.
Traction control system (TCS) The warning light
comes on for a few seconds when the ignition is switched on.
The warning light comes on when driving when a control cycle is activated.
The warning light lights up permanently if there is a fault in the TCS system.
The fact that the TCS system operates together with the ABS means that the TCS
warning light will also come on if the ABS system is not operating properly.
If the warning light comes on immediately after starting the engine, the TCS
system can be switched off for technical reasons. In this case, the TCS system can
be switched on again by switching the ignition on and off. If the warning light
goes out, the TCS system is fully functional again.
Further information about the TCS ⇒ page 154, Traction control system (TCS)
.Note
If the battery has been disconnected and reconnected, the warning light comes
on after switching on the ignition. The warning light must go out after driving a
short distance. Anti-spin regulation (ASR) The TCS system is switched off by pressing the button
⇒ fig. 138 and the warning
light lights up.
Electronic stability programme (ESP) The warning light
comes on for a few seconds when the ignition is switched on.
When the ESP is just actively stabilizing the vehicle, the warning light flashes in
the instrument cluster.
The warning light lights up permanently if there is a fault in the ESP system.
The fact that the ESP system operates together with the ABS means that the ESP
warning light will also come on if the ABS system is not operating properly.
If the warning light comes on immediately after starting the engine, the ESP
system can be switched off for technical reasons. In this case, the ESP system can
be switched on again by switching the ignition on and off. If the warning light
goes out, the ESP system is fully functional again.
Further information on the ESP ⇒
page 153, Electronic stability programme (ESP).
Electronic Differential Lock (EDL)
The EDL is a part of the ESP. A fault in the EDL is indicated by the lighting up of
the ESP warning light in the instrument cluster. Have the vehicle inspected imme-
diately by your specialist garage. Further information on the EDL ⇒ page 154,
Electronic Differential Lock (EDL). Note
If the battery has been disconnected and reconnected, the warning light comes
on after switching on the ignition. The warning light must go out after driving a
short distance.
Selector lever lock If the
green warning light lights up, operate the brake pedal. This is necessary,
in order to be able to move the selector lever out of the position P or N.

Driving Tips
Intelligent technology Electronic stability programme (ESP)
General Fig. 137 ESP system: Switch for TCS
The ESP aids you in maintaining control of your vehicle in situations in which the
vehicle is driving at its dynamic limits, such as entering a curve fast. The risk of
skidding is reduced and your car thus offers greater driving stability depending on
the conditions of the road surface. The system operates at all speeds.
The following systems are integrated into the electronic stability programme:
● Electronic Differential Lock (EDL),
● Traction control system (TCS),
● active driver-steering recommendation (DSR),
● Antilock brake system (ABS),
● Brake Assist,
● Uphill Start Assist.
The ESP system cannot be switched off with the
⇒ fig. 137 button; only the TCS
system is switched off, the warning light in the instrument cluster lights up. 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 individual systems. It al-
so processes additional measurement data which are supplied by highly sensitive
sensors: the rotational velocity of the vehicle about its vertical axis, the lateral ac-
celeration 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 be-
haviour 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.
During an intervention of the system, the warning light flashes in the instru-
ment cluster ⇒
page 27.
The ESP operates in combination with the ABS ⇒ page 157, Antilock brake system
(ABS). If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light lights up in the instrument cluster when there is a fault on
the ESP ⇒ page 27. WARNING
It is also not possible for the ESP to overcome the physical limits of the vehi-
cle. 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 par-
ticularly 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! £ 153

Note
● All four wheels must be fitted with the same tyres in order to achieve prob-
lem-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 another combi-
nation of tyres and wheels) can influence the function of the ESP ⇒
page 207,
Accessories, changes and replacement of parts.
Electronic Differential Lock (EDL) The electronic differential lock prevents an individual wheel from
slipping.
General
The EDL makes it much easier, and sometimes at all possible, to start off, acceler-
ate and climb a steep hill when the conditions of the road surface are unfavoura-
ble.
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 sen-
sors. 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 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.
EDL Off-road
After switching on the Off-road mode ⇒ page 160
, EDL Off-road is activated.
EDS Offroad assists vehicle traction when driving on unfirm ground.
EDL is activated earlier in the Off-road mode than in the normal mode. The brake
pressure builts up more quickly on the slipping wheel, on one axle, as well as diag-
onally. WARNING
● Carefully depress the accelerator when accelerating on uniformly slippery
road surfaces, such as ice and snow. The driven wheels might still spin despite
the EDL and affect the stability of the vehicle - risk of an accident!
● You should always adapt your style of driving to the condition of road sur-
face and to the traffic situation even when your vehicle is fitted with EDL. The
increased safety offered must not tempt you to take greater risks than other-
wise - risk of an accident! Note
● If the ABS or ESP warning light comes on, this may also indicate a fault in the
EDL. Have the vehicle inspected by your specialist garage as soon as you can.
● Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the EDL ⇒
