Starting-off and Driving
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 away and 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 ⇒ p age 179.
● 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 pre-glow period being
controlled automatically in line with the coolant temperature and outside temper-
ature.
The pre-glow 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 away and wait for about 30 seconds before repeating the attempt.
● It is possible that the fuse on the diesel pre-glow system is defect if the en-
gine still does not start. Check the fuse and replace it if necessary ⇒ p age 179.
● 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 into position
⇒ f ig.
78.
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 ⇒ p age 150, Working in the engine compartment.
