A fault on the engine oil level sensor is indicated additionally by an audible signal
and the warning light coming on several times after the ignition has been switched
on.
In this case have the engine inspected without delay by a specialist garage.
The following text will be displayed in the information display*:
OIL SENSOR WORKSHOP!
WARNING
•
If you must stop for technical reasons, then park the vehicle at a safe
distance from the traffic and switch off the engine and switch on the hazard
warning light system ⇒page 56.
•
The red oil pressure light

is not an oil level indicator! One should
therefore check the oil level at regular intervals, preferably after every refu-
eling stop.
•
Pay attention to the following instructions ⇒page 185, “Working in the
engine compartment” before checking the coolant fluid level and opening
the bonnet.
Open door*

The warning light
 comes on if one or several doors, the bonnet or boot lid is
opened.
The warning light comes on even when the ignition is switched off. The warning
light goes out 5 minutes after switching off the ignition if one or several doors, the
bonnet or boot lid is opened. The warning light goes out after closing the doors.
Windshield washer fluid level*

The warning light
 comes on when the ignition is switched on if there is insuffi-
cient fluid in the windshield washer system. Top up with liquid ⇒page 196.
A peep sounds as an additional warning signal.The following text will be displayed in the information display*:
REFILL WASHER LIQUID
Control system for exhaust

The warning light
 comes on after the ignition has been switched on.
If the warning light does not go out after starting the engine or it lights up when
driving, a fault exists in an exhaust relevant component. The engine management
system selects an emergency programme which enables you to drive to the nearest
specialist garage by adopting a gentle style of driving.
The following text will be displayed in the information display*:
EXHAUST WORKSHOP!
Traction control system (TCS) *

The warning light
 comes on for a few seconds when the ignition is switched on.
The warning light flashes when a control cycle is activated while driving.
The warning light will come on and remains on if the TCS is switched off or if there
is a fault in the 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 156.
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.

HandbrakeApplying the handbrake
– Pull the handbrake lever up fully.
Releasing the handbrake
– Pull the handbrake lever up slightly and at the same time press in the
locking button ⇒fig. 122.
– Hold the button pressed and push the handbrake lever down fully
⇒.The handbrake warning light
 lights up when the handbrake is applied, provided
the ignition is on.
A warning signal sounds and the following text appears in the display* if you have
inadvertently driven off with the handbrake applied:
HANDBRAKE ON
The handbrake warning is activated if you drive at a speed of more than 6 km/h for
more than 3 seconds.
WARNING
•
Please note that the handbrake must be fully released. A handbrake
which is only partially released can result in the rear brakes overheating
which will have a negative effect on the operation of the brake system - risk
of accident! In addition this can result in premature wear of the rear brake
pads.
•
Never leave children unattended in the vehicle. The children might, for
example, release the handbrake or take the vehicle out of gear. The vehicle
might then move off - risk of accident!Caution
After the car has come to a stop, always first of all apply the handbrake firmly before
then additionally engaging a gear (manual gearbox) or moving the selector lever
into position P (automatic gearbox).Parking aid*The parking aid provides a warning of obstacles behind the vehicle.The audible parking aid determines the distance between the rear bumper and an
obstacle located behind the vehicle with the aid of ultrasound sensors. The sensors
are integrated in the rear bumper.

Starting-off and Driving 104Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle (area
⇒page 103, fig. 123). The interval between the warning signals becomes
shorter as the clearance is reduced.
A continuous tone sounds from a distance of approx. 30 cm (area ) - danger area.
You should not reverse any further after this signal sounds!
Activating
The parking aid is activated automatically when reverse gear is engaged and the
ignition is turned on. This is confirmed by a brief acknowledgement signal.
Deactivating
The parking aid is deactivated by removing the reverse gear.
WARNING
•
The parking aid is not a substitute for the driver paying proper attention
and it is always the driver's responsibility to take care when parking the
vehicle or carrying out similar manoeuvres.
•
You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin post, trailer drawbar etc., behind your
vehicle. Such an obstacle might not be within the range detected by the
sensors.Note
•
When operating with a trailer, the parking aid is without function.
•
A system fault is indicated if a warning signal sounds for about 5 seconds after
switching the ignition on and engaging reverse gear and there is no obstacle close
to your vehicle. Have the fault rectified by a specialist workshop.
•
The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
•
If the parking aid is activated and the selector lever of the automatic gearbox is
in the position , warning signal indicates interruption (vehicle can no longer
move).
Cruise control system (CCS)*IntroductionThe cruise control system (CCS) maintains a constant speed, more than 30 km/h,
once it has been set, without you having to depress the accelerator pedal. This is
only possible within the range which is permitted by the power output and braking
power of the engine. The cruise control system makes it possible - particularly on
long journeys - for you to rest your “accelerator foot”.
WARNING
•
The cruise control system must not, for safety reasons, be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads or
loose chippings) - risk of accident!
•
In order to prevent unintentional use of the cruise control system, always
switch off the system after use.Note
•
Models fitted with a manual gearbox: Always depress the clutch pedal if you
switch on the cruise control system when the gearbox is in Neutral. Otherwise the
engine can rev up unintentionally.
•
The cruise control system is not able to maintain a constant speed when driving
on steep downhill sections. The weight of the vehicle increases the speed at which
it travels. One should shift down in good time to a lower gear or slow the vehicle
down by applying the foot brake.
•
It is not possible on vehicles fitted with an automatic gearbox to switch on the
cruise control system if the selector lever is in the position P, N or R.

Technical Data
Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral
The ESP aids you maintain control of your vehicle in situations in borderline driving
situations such as when negotiating a curve too fast. The risk of skidding is reduced
and your vehicle 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 individual 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 accel-
eration 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 vehicle 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 under-
steer (tendency to shift out of the curve). This braking control cycle is accompanied
by noises.
The ESP operates in combination with the ABS ⇒page 159, “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 35.
Switching off
You can switch the ESP off and on again as you wish, by pressing the button
⇒fig. 165. The ESP warning light lights up in the instrument cluster when the ESP is
switched off
 ⇒page 35.
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 vehicle 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 other-
wise - 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 another combi-
nation of tyres and wheels) can influence the function of the ESP ⇒page 204,
“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 transmitted 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 159, “Antilock brake system
(ABS)*”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light lights up in the instrument cluster when there is a fault on the
TCS
 ⇒page 34.
Switching off
You can switch the TCS off and on again as you wish by pressing the button
⇒fig. 166. The TCS warning light lights up in the instrument cluster when the TCS is
switched off

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 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
•
Carefully depress the accelerator when accelerating on uniformly slip-
pery 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
surface 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
otherwise - risk of an accident!Note
•
If the ABS or TCS or ESP warning light comes on, this may also indicate a fault in
the EDL. Please have the vehicle inspected as soon as possible by a specialist
garage.
•
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 ⇒page 204,
“Accessories, changes and replacement of parts”.

Intelligent Technology 160brake pedal firmly and hold it in this position in order to achieve the shortest
possible braking distance.
The Brake Assist is able to help you achieve a shorter braking distance in emergency
situations by rapidly producing the pressure required in the brake system. It fully
exploits the attributes of the ABS. After you release the brake pedal, the function of
the Brake Assist is automatically switched off and the brakes operate in the normal
way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist
function is also not available. Further information on the ESP ⇒page 155.
WARNING
•
The Brake Assist is also not able to overcome the physical limits of your
vehicle in terms of the braking distance required.
•
Adapt your speed to the conditions of the road surface and to the traffic
situation.
•
The increased safety offered by the Brake Assist must not tempt you to
take a greater safety risk than otherwise.
Electrohydraulic power steeringThe 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.
If there is a fault in the power steering, the warning light lights up in the instrument
cluster
 ⇒page 29.
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 rolling circumference of the individual wheels. If the tyre
inflation pressure is significantly changed and thus the rolling circumference of a
wheel, the warning light
