78•If the brake warning lamp lights up together with the ABS warning
lamp, this can mean that there is a fault in the ABS control function. As a
result, the rear wheels can lock relatively easily when braking. Under
certain circumstances, the rear of the vehicle could suddenly sway from
side to side, with the subsequent dang er of skidding. Drive carefully to the
nearest specialised workshop and have the fault repaired.
Fault in the cooling system
Faults in the cooling system must be repaired immediately.If the
symbol flashes in the display, this means that either the
coolant temperature is too high or the coolant level is too low. The
following message will appear in the display together with the
symbol:
Switch off engine and check coolant level
– Stop the vehicle.
– Switch the engine off.
– Check the coolant level ⇒page 234.
– Add more coolant if necessary ⇒page 235.
– Wait for the symbol to go out before driving on.
– Obtain professional assistance if necessary.
If the coolant level is correct, the overheating may be caused by a malfunction
of the radiator fan. If the alternator warning lamp lights up as well
⇒page 69, it is possible that
the drive belt has broken.
Caution
Do not drive on if the symbol

Tyre pressure monitoring*Introduction
The tyre pressure monitoring system constantly checks the
pressure of the tyres.The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument panel display. The system works
with the help of the ABS sensors in the wheels.
Please bear in mind that the tyre inflation pressure is also influenced by the
temperature of the tyre. Tyre pressure increases about 0.1 bar for each 10 °C
in tyre temperature increase. The tyre heats up while the vehicle is being
driven and the tyre pressure will rise accordingly. Therefore, you should only
adjust the tyre pressures when they are
cold (i.e. approximately at ambient
temperature).
To ensure that the tyre pressure monitoring system works reliably, you should
check and, if necessary, adjust the tyre pressures at regular intervals and
store the correct pressures (reference values) in the system.

WARNING
•Never adjust tyre pressure when the tyres are hot. This may damage or
even burst the tyres. Risk of accident!•An insufficiently inflated tyre flexes a lot more at high speeds and
causes significant heating of the tyre. Under these conditions, the tyre
bead may be released or the tyre may burst. Risk of accident!For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear.
Note
•Responsibility for ensuring that the tyres are correctly inflated remains
with the driver; the system can only provide assistance.•Pressure can only be adjusted when the tyres are at ambient
temperature.

The Electronic Stability Programme (ESP) contains the electronic differential
lock (EDL) and the traction control system (TCS). The ESP function works
together with the ABS. If a fault in the ABS occurs, both warning lamps light
up, but if the ESP fails, only the ESP warning lamp lights up.
The ESP is started automatically when the engine is started.
The ESP switch deactivates both TCS and ESP functions. The ESP, in spite of
being deactivated, will always self-connect when necessary if brakes are
being used.
The TCS can be deactivated when in cases where wheel sliding is desirable.
For example:
•When driving with snow chains,•when driving in deep snow or on loose surfaces,•when rocking the vehicle backwards and forwards to free it from mud, for
example.
Next, the button should be pressed to reactivate the TCS.
When does the warning lamp switch on or flash?•On switching the ignition on, it lights up for about two seconds to carry
out a function control.•The warning lamp will start flashing when the vehicle is moving if the ESP
or the TCS is activated.•It will light up continuously if there is a malfunction in the ESP.WARNING
•The Electronic Stability Programme (ESP) cannot defy the laws of
physics. This should be kept in mind, particularly on slippery and wet
roads and when towing a trailer.•Always adapt your driving style to suit the condition of the roads and
the traffic situation. Do not let the extra safety afforded by ESP tempt you
into taking any risks when driving, as this can cause accidents.
•Please refer to the corresponding warning notes on ESP in ⇒page 191,
“Intelligent technology”.

Practical TipsIntelligent technologyElectronic Stability Programme (ESP)General notes
The Electronic Stability Programme increases the vehicle's
stability on the road.The ESP is designed to increase the degree of control in situations where the
vehicle approaches the limits of adhesion, especially when accelerating and
cornering. It reduces the risk of skidding and improves stability in all road
conditions. The system is active across the entire speed range. The anti-lock brake system (ABS), the electronic differential lock (EDL) and
the traction control system (TCS) are all integrated into the Electronic Stability
Programme.
How it works
The ESP control unit processes data from the three integrated systems. It also
processes additional inputs provided by other high-precision sensors. These
register the vehicle's rotation about the vertical axis (yaw rate), lateral accel-
eration, brake pressure and steering wheel angle.
The system uses the steering wheel angle and road speed to 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 vehicle 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 over
swerves (tendency of the rear to leave the road),
the brakes will act on the front wheel facing the outside of the bend. If the
vehicle under swerves (tendency to leave the bend), the braking force is
applied to the rear wheel facing the inside of the bend.
The ESP works in conjunction with the ABS ⇒page 192. If a malfunction
should occur in the ABS, the ESP will also stop working.
Deactivating
The ESP is activated automatically when the engine is started and performs a
self-test routine.

192If required, the ESP can also be enabled and disabled manually by briefly
pressing the button ⇒ page 191, fig. 160. The ESP warning lamp lights
up when the system is switched off, see ⇒page 68.
In general, the ESP should be left switched on at all times. In particular
circumstances where a certain amount of wheel slip is desirable, it may be
advisable to switch off the ESP. Examples:•when driving with snow chains•when driving in deep snow or on loose surfaces•when rocking the vehicle backwards and forwards to free it.
The ESP should be switched on again afterwards as soon as possible.WARNING
The ESP is not able to overcome the physical limits of adhesion. Even with
ESP, you should always adjust your speed to suit the conditions. Please

extra safety features tempt you into taking any risks when driving. Failure
to do so could result in an accident.Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking.The anti-lock brake system (ABS) is an important part of the vehicle's active
safety system. However, the ABS will not necessarily guarantee shorter stop-
ping distances in all conditions. For instance, on loose gravel or fresh snow
on top of an icy surface (conditions which anyway require extreme care and
reduced speed), the stopping distance with ABS may even be slightly longer. How the ABS works
The system runs an automatic self-check when the vehicle reaches a road
speed of about 6 km/h. This may be accompanied by a noise from the ABS
pump.
When one of the wheels is turning very slowly in relation to the road speed
and is close to locking up, the system will reduce the brake pressure on that
wheel. The driver is made aware of this adjustment process by a vibration of
the brake pedal
and an audible noise. This is a deliberate warning to the
driver that one or more of the wheels is tending to lock up and the ABS control
function has intervened. In this situation it is important to keep the brake
pedal fully depressed so the ABS can regulate the brake application, but do
not “pump” the brake pedal.
WARNING
The grip provided by ABS is still subjec t to the physical limits of adhesion.
Always bear this in mind, especially on wet or slippery roads. If you notice
that the ABS is working (to counteract locked wheels under braking), you
should reduce speed immediately to suit the road and traffic conditions. Do
not let the extra safety features tempt you into taking any risks when
driving. Failure to do so could result in an accident.
Note
If a malfunction should occur in the ABS, this is indicated by a warning lamp
⇒ page 67.

Brake assist system
The brake assist system helps the driver to achieve optimum
braking effect.The brake assist system helps to increase braking power and thus to achieve
a shorter stopping distance. If the driver presses the brake pedal very quickly,
the brake assist system automatically boosts the braking force to the
maximum level, up to the point where the anti-lock brake function (ABS) inter-
venes to stop the wheels from locking. You should then keep the brake pedal
pressed until the vehicle has braked to the required speed. The brake assist
system switches itself off as soon as you release the brake pedal.
The brake assist system will not be operative if there is a malfunction in the
ABS or the ESP.
WARNING
Please remember that the accident risk always increases if you drive too
fast, especially in corners or on a slippery road, or if you follow too close
behind the vehicle in front of you. An increased accident risk cannot be
compensated even by the brake assist system.Electronic differential lock (EDL)
The electronic differential lock prevents the loss of traction
caused if one wheel starts spinning.General notes
The electronic differential lock (EDL) helps the vehicle to start moving, accel-
erate and climb a gradient in slippery conditions where this may otherwise be
difficult or even impossible. How it works
The EDL works automatically, without the driver's involvement. With the aid
of the ABS sensors, the system monitors the rotational speed of the drive
wheels
⇒page 192. If a considerable difference in revs is detected (approx.
100 rpm) in the speed of the drive wheels, e.g. when only one part of the
surface supporting the wheels is slippery, the system applies the brake to
slow down the skidding wheel so that more of the power is directed to the
other wheels. The systems works up to a speed of approx. 80 km/h. The
system will make noise while it is working.
Starting the vehicle
If one wheel has less grip and starts spinning (for instance, if one of the drive
wheels is on ice), keep pressing the accelerator gradually until the vehicle
starts moving.
Overheating of the brakes
To prevent the brake disk of the braked wheel from overheating, the EDL cuts
out automatically if subjected to excessive loads. In this case, the vehicle will
continue to run and will have the same running properties as those of another
without EDL.
The EDL will switch on again automatically when the brake has cooled down.
WARNING
•When accelerating on a uniformly slippery surface (for instance all four
wheels on ice or snow), press the accelerator gradually and carefully.
Despite EDL, the drive wheels may otherwise start to spin. This could
impair the vehicle's stability. Risk of accident.•Even with EDL, you should always adjust your speed to suit the road and
traffic conditions. Do not let the extra safety features tempt you into taking
any risks when driving. Failure to do so could result in an accident.
