Safety First Operating Instructions Practical Tips Technical Specifications
– Turn the ignition key to position without pressing the acceler-
ator.
– Release the ignition key as soon as the engine starts (the starter
motor must not be allowed to run on with the engine).
Vehicles with a diesel engine:
– Use the foot brake.
– Manual gearbox: Push the clutch pedal all the way down.
– Move the gear lever into neutral (automatic gearbox: selector
lever to P or N) ⇒ .
– Turn the ignition key to position . The pre-heating indicator
light
D comes on while the glow plugs are preheating.
– When the indicator light
D goes out, turn the ignition key to
position . Do not press the accelerator.
– Release the ignition key as soon as the engine starts (the starter

When starting a very cold engine, it may be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern.
If the engine fails to start straight away, stop after 10 seconds and try again
after about half a minute.
Glow plug system*
To assist starting at low temperatures, diesel engines are equipped with a
glow plug preheating system. The preheating time depends on the coolant
temperature and the outside temperature. Start the engine as soon as the
glow plug indicator light
D goes out.
When the engine is warm or at outside temperatures above +8 °C, the glow
plug indicator light will only come on for about one second. This means that
the engine can be started immediately.
If the engine will not start...

WARNING
Never run the engine in confined spaces, as the exhaust gases are
poisonous.
Caution
Avoid high engine speeds, full throttle and extreme load conditions until the
engine has reached its normal operating temperature, otherwise this can
damage the engine.
For the sake of the environment
Do not warm up the engine by running the engine with the vehicle stationary.
Start immediately. This will help avoid unnecessary exhaust emissions.
Stopping the engine
– Turn the ignition key to position ⇒ page 174, fig. 148.
WARNING
• Never switch the engine off until the vehicle is stationary.
