•The exhaust pipe of the auxiliary heating is located on the
underside of the vehicle. Therefore do not place the vehicle, if you
wish to operate the auxiliary heating, in such a way that the exhaust
gases of the auxiliary heating can come easily into contact with
inflammable materials (e.g. dry grass) or easily inflammable
substances (e.g. fuel run out).
Note
•If the auxiliary heating runs, the fuel consumption comes from the
vehicle tank. Therefore the auxiliary heating should not be operated, if
there is very little fuel in the tank.
•The exhaust pipe of the auxiliary heating, which is located on the
underside of the vehicle, must not be clogged and the exhaust flow must
not be blocked.
•If the auxiliary heating and ventilation is running, the vehicle battery
discharges. If the auxiliary heating and ventilation has been operated
several times over a longer period, the vehicle must be driven a few kilom-
eters in order to recharge the vehicle battery.
•The auxiliary heating only switches the blower on, if it has achieved a
coolant temperature of approx. 50 °C.
•At low outside temperatures, this can result in a formation of water
vapour in the area of the engine compartment. This is quite normal and is
not an operating problem.
•After switching off the auxiliary heating, the coolant pump runs for a
short period.
•The auxiliary heating and ventilation does not switch on or comes on,
if the vehicle battery indicates a low loading state.
•The auxiliary heating (auxiliary heating) switches on, if in the informa-
tion display: Please refuel! is indicated or was indicated before switching
off the ignition.
•When driving, the auxiliary heating can only be switched on, if the exte-
rior temperature is lower than 5 °C.
•The air inlet in front of the windscreen must be free of ice, snow or
leaves in order to ensure that the auxiliary heating operates properly.
•So that the warm air can flow into the vehicle interior after switching on
the auxiliary heating (auxiliary heating), the control dial ⇒page 119,
fig. 116 must be turned up to the stop to the right when heating. With
Climatic and Climatronic, you can maintain the temperature normally
selected by you (we recommend 22 °C). It is recommended to put the air
flow in the position
. For heating and climatic put the blower switch
⇒ page 119, fig. 116 if necessary ⇒page 124, fig. 119 in the position 2.

- 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To lock the steering , with the ignition key withdrawn, turn the steering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 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 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 the ignition lock
prevents the starter being engaged when the engine is running and thus
getting damaged.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
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 288.
•Contact the nearest specialist garage to obtain professional assist-
ance.
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 temperature.
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 ve hicle 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 288.
•Contact the nearest specialist garage to obtain professional assist-
ance.
Starting the engine after the 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 the engine off
– The engine can be switched off by turning the ignition key from position ⇒page 139, fig. 129 into position .
WARNING
•Never switch off the engine before the vehicle is stationary - risk
of accident!
•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.

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 hand-
brake which is only partially released can result in the rear brakes
overheating which will have a nega tive 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 the first gear (manual gearbox) or
moving the selector lever into position P (automatic gearbox).

Front and rear parking aid*
The parking aid provides a warning of obstacles in front
and behind the vehicle.
The audible parking aid determines the distance between the front or rear
bumper and an obstacle with the aid of ultrasound sensors. The sensors
are integrated in the front and rear bumper. The signal tones for the front
parking aid sound higher than for the rear parking aid.
Range of sensors
The distance warning begins at a distance of about 120 cm from the
obstacle in front of the vehicle (area ⇒fig. 134 ) and about 160 cm from
the obstacle behind the vehicle (area ⇒page 144, fig. 132 ). The
interval between the warning signals becomes shorter as the clearance is
reduced.
A continuous tone sounds from a clearance of just 30 cm (Bereich ) -
danger area. You should not reverse any further after this signal
sounds!
Your vehicle can be equipped with a radio which shows on its display the
distance of the vehicle to the obstacle. You can also switch off this func-
tion - see operating instructions for radio
Activating
The parking aid is activated when the reverse gear is engaged and the
ignition is turned on or by pressing the button ⇒fig. 133 - the symbol
lights up in the button. The activation is confirmed by a brief acknowledge-
ment signal.
Deactivating
The parking aid is deactivated after pressing the button
⇒ fig. 133 or at
a speed of more than 15 km/h - the symbol in the button is no longer
illuminated.
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 reversing the vehicle or carrying out similar manoeuvres.
