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 warm air can flow into the vehi
cle interior after switching on the auxil-
iary heating, you must maintain the te
mperature normally selected by you (we
recommend 22°C). It is recommended to
put the air flow in the position

On vehicles with DPF (diesel particle filter) the warm coolant heats up the
engine.Direct switching on/offThe auxiliary heating (auxiliary heating and ve

Starting-off and Driving
124
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 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 ma
y 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 no
rmal 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 252.
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 256.
WARNING
•
Never run the engine in non ventilat
ed 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 uncon-
sciousness 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 i
mmediately 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 oper
ating temperature - risk of damaging the
engine!•
Vehicles which are fitted with an exhaus
t gas catalytic conver
ter 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 vehi
cle is standing. Drive off right away.
Through this the engine reaches its operating temperature 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 befo
re 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 258.
•
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 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 temper-ature. The preglow indicator light
 comes on after the igniti
on has been switched on.

•
Make sure that the valve is not pressed into the filler tube when inserting the
pump nozzle into the filler tube. Otherwis
e you are unintentionally filling up the
volume, which in case of heat can cause an
expansion of the fuel. This can lead to
an overflow of fuel or damage
to parts of the fuel reservoir.

provided the nozzle has been operated properly. Do not continue refuelling - otherwise the expansion volume is filled up.
