also come on together with the separate lights for daylight driving lights when ac-
tivating the function daylight driving lights.
Halogen projector headlights with cornering light function For a better cornering illumination, the halogen projector headlights with corner-
ing light function are set in the optimal position in line with the vehicle speed and
the steering angle.
If the warning light
comes on while driving or after the ignition is switched on, a
fault is confirmed. WARNING
If there is a fault in the halogen projector headlights with cornering light func-
tion, the warning light lights up in the instrument cluster. The halogen pro-
jector headlights with cornering light function are automatically lowered to
the emergency position, which prevents a possible dazzling of oncoming traf-
fic. Thus the illuminated length of the road is shortened. Drive carefully and
have the car inspected immediately by a specialist garage.

- start engine
Applies to all models:
Position 1 To
lock the steering , with the ignition key withdrawn, turn the steering wheel un-
til the steering locking pin is heard to engage. You should always lock the steering
as a general rule if you leave your vehicle. This acts as a deterrent against possible
theft of your vehicle ⇒ .
Position 2 Move the steering wheel back and forward a little if the ignition key cannot, or
cannot easily be turned into this position, in order to release the steering lock.
Position
3 The engine is started in this position. At the same time switched on low beam or
main beam or other electrical components with major power consumption are
briefly switched off. The ignition key moves back into position
2 when one relea-
ses the key.
The ignition key must be turned back into position 1 each time before starting
the engine again. The starter repeat lock in the ignition lock prevents the starter
being engaged when the engine is running and thus getting damaged. WARNING
● When driving, the ignition key must always be in the position 2 (ignition
switched on) without the engine running. This position is indicated by the
warning lights coming on. If this is not the case, it could result in unexpected
locking of the steering wheel - risk of accident!
● Do not withdraw the ignition key from the lock until the car has come to a
stop. The steering lock can engage immediately - risk of accident!
● Always withdraw the ignition key if you are going to leave the vehicle,
even for a short time. This is particularly important if children are left in the
vehicle. The children might otherwise start the engine or operate electrical
equipment (e.g. power windows) - risk of injury! Starting the engine
General You can only start the engine only using an original ignition key.
● Place the gearshift lever into neutral (or place the selector lever to the posi-
tion P or N in the case of an automatic gearbox) and put on the handbrake firmly
before starting the engine.
● The clutch pedal should be fully depressed when starting the engine which
means that the starter only has to crank the engine.
● Let go of the key as soon as the engine starts otherwise there may be damage
to the starter.
The engine running noises may louder at first be louder for a short time after
starting the cold engine until oil pressure can be built up in the hydraulic valve
clearance compensation. This is quite normal and is not an operating problem.
If the engine does not start ...
You can use the battery of another vehicle as a jump-start aid ⇒ page 178. WARNING
● Never run the engine in non ventilated or enclosed areas. The exhaust
gases of the engine contain besides the odorless and colourless carbon mon-
oxide a poisonous gas - hazard! Carbon monoxide can cause unconsciousness
and death.
● Never leave your vehicle unattended with the engine running. CAUTION
● The starter may only be operated (ignition key position 3 ), if the engine is not
running. If the starter is immediately operated after switching off the engine, the
starter or the engine can be damaged.
● Avoid high engine revolutions, full throttle and high engine loads as long as
the engine has not yet reached its normal operating temperature - risk of damag-
ing the engine!
● Do not tow start the engine - danger of damaging the engine. On vehicles with
a catalytic converter, unburnt fuel may get into the catalytic converter where it
may ignite. This in turn may damage or destroy the catalytic converter. You can
use the battery of another vehicle as a jump-start aid ⇒ page 178, Jump-starting.£ 83
Starting-off and Driving Using the system Safety Driving Tips General Maintenance Breakdown assistance Technical data
For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away.
When driving the engine reaches its operating temperature more rapidly and the
pollutant emissions are lower.
Petrol engines These engines are fitted with a starter system which selects the correct fuel-air
mixture for every external air temperature.
●
Do not operate accelerator before and when starting engine.
● Interrupt the attempt at starting after 10 seconds if the engine does not start
right awayand wait for about 30 seconds before repeating the attempt.
● It is possible that the fuse on the electrical fuel pump is defect if the engine
still does not start. Check the fuse and replace it if necessary ⇒ page 182.
● If the engine does not start, contact the nearest specialist garage to obtain
professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator
after the engine has started.
Diesel engines Glow plug system
Diesel engines are equipped with a glow plug system, the preglow period being
controlled automatically in line with the coolant temperature and outside temper-
ature.
The preglow indicator light
comes on after the ignition has been switched on.
You should not switch on any major electrical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.
● You should start the engine immediately after the glow plug warning light
has gone out.
● The glow plug warning light will come on for about one second if the engine is
at a normal operating temperature or if the outside temperature is above +5°C.
This means that you can start the engine right away.
● Interrupt the attempt at starting after 10 seconds if the engine does not start
right awayand wait for about 30 seconds before repeating the attempt. ●
It is possible that the fuse on the diesel preglow system is defect if the engine
still does not start. Check the fuse and replace it if necessary ⇒ page 182.
● Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel tank
has run completely dry - up to one minute. This is because the fuel system must
first of all be filled while the attempting to start the engine.
Switching off the engine –
The engine can be switched off by turning the ignition key from position
⇒ fig. 82 into position 1 .
WARNING
● Never switch off the engine before the vehicle is stationary - risk of acci-
dent!
● The brake booster only operates when the engine is running. Greater
physical effort for braking is required when engine is switched off. Because if
you do not stop as normal, this can cause an accident and severe injuries. CAUTION
you should not switch the engine off right away at the end of your journey after
the engine has been operated for a lengthy period at high loads but should be al-
lowed it to run at idling speed for about 2 minutes. This prevents any accumula-
tion of heat when the engine is switched off. Note
● The radiator fan may continue running for a further 10 minutes or so after the
engine and the ignition have been switched off. The coolant fan may, however, al-
so switch on again after some time if the coolant temperature rises because of an
accumulation of heat in the engine or if the engine is warm and the engine com-
partment is additionally heated by strong sunlight.
● This is why particular care is required when carrying out any work in the en-
gine compartment ⇒ page 153
, Working in the engine compartment. 84
Starting-off and Driving
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 Information display
if you have inadvertently driven off with the handbrake applied:
Release parking brake! (Release parking brake!)
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 ex-
ample, 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 be-
fore 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.
Fig. 85 Parking aid: Range of sensorsThe audible parking aid determines the distance from the rear bumper to an ob-
stacle behind the car with the aid of ultrasound sensors. The sensors are integra-
ted in the rear bumper.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the obstacle
(area
A ⇒
fig. 85 ). 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 B ) - danger
area. You should not reverse any further after this signal sounds! If the vehicle is
equipped with a factory-fitted towing device, the indication threshold of the dan-
ger area starts - continuous tone
- 5 cm further behind the vehicle. The vehicle
can be extended through an installed detachable towing device.
On factory-fitted radio navigation systems and car stereos, the distance to the ob-
struction can also be shown graphically in the display. On vehicles with a factory-
fitted towing device, the rear sensors are deactivated when towing a trailer. The
driver is informed about this by a graphic display (vehicle towing a trailer) in the
radio or the radio navigation display. The factory-fitted radio or navigation system
can be set so that the play function volume decreases when activating the park-
ing aid, see Owner's Manual radio or radio navigation system. As a result, the sig-
nal tones from the parking aid can be better recognised.
Activating
The parking aid is activated automatically when reverse gear is engaged and the
ignition is turned on. This is confirmed by a brief audible signal.
Deactivating
The parking aid is deactivated by disengaging the reverse gear or by switching the
ignition off. £86
