•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.

– Pull the lever below the steering column ⇒fig. 127 down ⇒.
– Set the steering wheel to the desired position (concerning height and forward/back position).
– Then push the lever up against the steering column until it locks into place.
WARNING
•You must not adjust the steering wheel when the vehicle is
moving!
•The driver must maintain a distance of at least 25 cm to the
steering wheel ⇒fig. 128 . Not maintaining this minimum distance
will mean that the airbag system will not be able to properly protect
you - hazard!
•For safety reasons the lever must always be firmly pushed up to
avoid the steering wheel altering its position unintentionally when
driving - risk of accident!
•If you adjust the steering wheel further towards the head, you
will reduce the protection offered by the driver airbag in the event
of an accident. Check that the steering wheel is aligned to the
chest.
•When driving, hold the steering wheel with both hands firmly on
the outer edge in the 9 o'clock and 3 o'clock position. Never hold

Ignition lock
Petrol engines
- ignition switched off, engine off, the steering can be locked.
- ignition switched on
- start engine
Diesel engines - interruption of fuel supply, ignition switched off, engine off, the
steering can be locked. - heating glow plugs on, ignition switched on
•You should not switch on any major electrical 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 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.
Ignition key withdrawal lock (automatic gearbox)
You can only withdraw the ignition key after switching off the ignition if the
selector lever is in position P.

WARNING
•When driving, the ignition key mu st always be in the ignition
lock in the position (ignition switched on) without the engine
running. This position is indicate d 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!
•Only remove the ignition key from the ignition lock when the
vehicle has come to a standstill (put on the handbrake or select the
selector lever position P). The steering lock might otherwise
engage unintentionally - 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 chil-
dren are left in the vehicle. The children might otherwise start the
engine or switch on electrical equipment (e.g. power windows) -
risk of accident or injury!
Starting 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
position P or N in the case of an automatic gearbox) and put on the hand-
brake 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 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 oper-
ating problem.
If the engine does not start ...
You can use the battery of another vehicle as a jump-start aid
⇒page 281.
It is only possible to tow-start vehicles fitted with a manual gearbox. The
tow-starting distance must not be more than 50 metres ⇒page 286.
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
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 ), 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 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. Through this 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 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.

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.
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, also switch on again after some time if the coolant temper-
ature rises because of an accumulation of heat in the engine or if the
engine is warm and the engine compartment is additionally heated by
strong sunlight.
•This is why particular care is required when carrying out any work in
the engine compartment ⇒page 248, “Working in the engine
compartment”.
Shifting (manual gearbox)
Shift into reverse only when the car is stationary. Depress the clutch pedal
and hold it fully depressed. Wait a moment before engaging reverse gear
in order to avoid any shift noises.
The reversing lights will come on once reverse gear is engaged, provided
the ignition is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
•One should not lay the hand on the shift lever while driving the vehicle.
The pressure of the hand will be transferred to the gearshift forks in the
gearbox. This can, over a period of time, lead to early wear of the gearshift
forks.

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 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).
