to unlock and lock the vehicle;
unlocking boot lid.
The transmitter with the battery is incorporat
ed in the handle of the master key. The
receiver is located in the interior of the car. The operating range of the remote control key is approx. 10 m. But this range can be reduced if the batteries are weak. The master key has a fold-open key bit which can be used for unlocking and locking the car manually and also for starting the engine. If a lost key is replaced or if the receiver unit has been repaired or a new unit installed, it is then necessary for a specialist garage to adapt the system. Only after this is it possible to again use the remote control.
Note
The remote control is automatically deactivated when the ignition is switched on.
The operation of the remote control may temporarily be affected by interference
from transmitters close to th
e car and which operate in the same frequency range (e.g.
mobile phone, TV transmitter).
The battery must be replaced if the centra
l locking or anti-theft alarm system does
not react to the remote control at less th
an 3 metres away. We recommend having the
battery replaced by
a specialist garage.

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 projec
tor headlights with
cornering light func-
tion, the warning light
lights up in the instrument cluster. The halogen
projector headlights with cornering light function are automatically lowered to the emergency position, which prevents a po
ssible dazzling of oncoming traffic.

You should not switch on any major elec
trical components during the heating
period otherwise
the vehicle battery will
be drained unnecessarily.
- start engine Applies to all models: Position
To lock the steering
, with the ignition key withdrawn, turn the steering wheel until the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
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
The engine is started in this position. At th
e same time switched on low beam or main
beam or other electrical components wi
th major power consumption are briefly
switched off. The ignition key moves back into position when one releases the key. The ignition key must be turned back into
position each time before starting the
engine again. The starter repeat lock in th
e ignition lock prevents the starter being
engaged when the engine is r
unning and thus getting damaged.
WARNING
When driving, the ignition key must always be in the position (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 wh
eel - risk of accident!
Do not withdraw the ignition key from the lock until the vehicle 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 en
gine or operate electrical equipment
(e.g. power windows) - risk of injury!
Starting the engineGeneral 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 position
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 - the starter
then 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 anothe
r vehicle as a jump-start aid
page 190.
It is only possible to tow-start vehicles fi
tted with a manual gearbox. The tow-starting
distance must not be more than 50 metres
page 193.
WARNING
Never run the engine in non ventilated
or enclosed areas. The exhaust gases
of the engine contain besides the odorless and colourless carbon monoxide a poisonous gas - hazard! Carbon mono
xide can cause unconsciousness and
death.
Never leave your vehicle unattended with the engine running.Caution
The starter may only be operated (ignitio
n key position ), if the engine is not
running. If the starter is imme
diately operated after switchin
g off the engine, the starter
or the engine can be damaged.

Technical Data
Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper
ating temperature - risk of damaging the
engine!
Vehicles which are fitted with an exhaust gas catalytic converter should not be tow-
started over a distance of more than 50 metres.
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 te
mperature more rapidly and the pollutant
emissions are lower.Petrol enginesThese 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 electric
al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary
page 195.
If the engine does not start, contact the nearest specialist garage to obtain profes-
sional assistance. It may be necessary, if the engine is
very hot
, to slightly depress the accelerator after
the engine has started.Diesel enginesGlow 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 tempera- ture. 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 195.
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 turnin
g the ignition key from position into
page 89, fig. 94
.
WARNING
Never switch off the engine before the ve
hicle is stationary - risk of accident!
The brake booster only operates when the engine is running. Greater phys-
ical effort for braking is required when en
gine 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 allowed it
to run at idling speed for about 2 minutes.
This prevents any accumulation of heat
when the engine is switched off.

The handbrake warning is acti
vated 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 firs
t 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 di
stance 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.
Range of sensors The clearance warning begins at a distance
of about 160 cm from the obstacle (area
fig. 97
). The interval between the warning si
gnals 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!
If the vehicle is
equipped with a factory-fitted
towing device*, the border of the danger area starts -
continuous tone - 5 cm further behind th
e vehicle. The vehicle can be extended
through an installed deta
chable towing device.
Activating The parking aid is activated automatically when
reverse gear
is engaged and the igni-
tion is turned on. This
is confirmed by a brief acknowledgement signal.
Deactivating The parking aid is deactivated by disengaging the reverse gear or by switching the igni- tion off.
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, trai
ler drawbar etc., behind your vehicle.
Such an obstacle might not be within the range detected by the sensors.
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the parking aid. Thus, these objects or people who wear such clothing are not recognised by the sensors of the parking aid.
Note
The parking aid does not operate if you
are towing a trailer (applies to models
which feature a factory-fitted towing device*).
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
