Do not continue your journey
if for some reason it is not possible under the
conditions prevailing
to top up with oil.
Keep the engine switched off
and obtain
professional assistance from a specialist garage, otherwise it could lead to severe engine damage. Do not drive any further
if the warning light remains on even if the oil is at the
correct level. Do not run the engine not at
idling speed either. Contact the nearest
specialist garage to obtain professional assistance. The following text will be displayed in the information display*:
STOP! OIL PRESS. STOP MOTOR! SERVICE MANUAL
The warning light

lights up yellow* (oil quantity too low)
If the warning light lights up yellow, there is not the correct quantity of oil in the engine. Check as soon as possible the oil level or top up
⇒page 163 with engine
oil. A peep sounds as an additional warning signal.The following text will be displayed in the information display*:
CHECK OIL LEVEL
When opening the bonnet, the warning light
goes out. If no engine oil has been
replenished, the warning light will come on again after driving about 100 km. The warning light

flashes yellow* (engine oil level sensor faulty)
A fault on the engine oil level sensor is in
dicated 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 inspecte
d without delay by a specialist garage.
The following text will be displayed in the information display*:
OIL SENSOR WORKSHOP!

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 re
sult in the rear brakes overheating
which will have a negative effect on th
e 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
Each time the vehicle is parked, first of
all apply the handbrake and then addition-
ally engage the 1st gear.Rear 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 th
e aid of ultrasound sensors. The sensors
are integrated in the rear bumper.

Range of sensors The clearance warning begins at a distance of about 160 cm from the obstacle (area ⇒page 97, fig. 108
). 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 confir
med by a brief acknowledgement signal.
Deactivating The parking aid is deactivated by removing the reverse gear.
WARNING
•
The parking aid is not a substitute fo
r the driver paying proper attention
and it is always the driver's responsibility to take care when parking the vehicle or carrying ou
t 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
•
The parking aid does not operate if you
are towing a trailer (applies to models
which feature a factory-fitted towing device*).•
If a warning signal sounds for about 3 seconds after switching the ignition on
and engaging reverse gear, and there is no ob
stacle close to your vehicle, this indi-
cates a system fault. 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.
Cruise control system (CCS)*IntroductionThe cruise control system (CCS) maintains a constant speed, more than 30 km/h (20 mph), once it has been set, without you
having to depress the accelerator pedal.
This is only possible within the range wh
ich is permitted by
the power output and
braking power of the engine. The cruise control system makes it possible - particu- larly 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: Al
ways 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.

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 vehi
cle about its vertical axis, the lateral accel-
eration of the vehicle, the brakin
g pressure and the steering angle.
The direction which the driver wishes to ta
ke 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 exis
t, 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 re
ar 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 135, “Antilock brake system
(ABS)*”. If there is a fault in the ABS system, the ESP also does not operate. The ESP warning light
⇒page 33 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
⇒ fig. 139
. The ESP warning light
⇒page 33 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 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 179,
“Accessories, changes and replacement of parts”.Electronic Differential Lock (EDL)* The electronic differential lock pr
events an individual wheel from
slipping.Vehicles fitted with ABS*
can be equipped with electron
ic 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 conditio
ns 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 proces
s 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 driv
en 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 sn
ow. 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 warning light comes on, this ma
y also indicate a fault in the EDL.
Please have the vehicle inspected as soon
as possible by a specialist garage.

Traction control system (TCS) The traction control system prevents
the driven wheels from spinning

Operating principle The TCS switches on automatically when th
e 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 redu
cing the engine speed. Th
is occurs at all speeds.
The TCS operates in combination with the ABS

Particularly if you drive a great deal in towns and over short distances or if you adopt a sporty style of driving, it may be neces- sary to have the thickness of the brake
pads inspected at a specialist garage
between the service inspections.
