If you press in the key
without pressing the clutch or brake pedal,
the ignition will be switched on or off. The steering lock is released
when the ignition is switched on. Diesel engines continue to be
automatically preheated.
The key can be removed only when the ignition is off. The key has to
be pressed in briefly to switch off the ignition. On vehicles with an
automatic gearbox, the selector lever has to be in position P.
Electrical components with a high power consumption are switched
off temporarily while you start the engine.
When starting from cold the engine may be a little noisy for the first
few seconds until oil pressure has built up in the hydraulic tappets.
This is quite normal and no cause for concern.
If the engine fails to start immediately, the starter will be switched
off automatically after a few seconds. Try to start the engine again.
Driving away from a standstill
On some vehicles, the engine revs are automatically increased
slightly as soon as you release the clutch. This helps you drive off
more smoothly.

ment such as the electric windows can be used. This could result
in serious injury.
•
Never leave children or disabled people alone in the car. The
doors could be locked with the re mote control key and the occu-
pants could become trapped in the vehicle. The vehicle occupants
could be exposed to extremely high or low temperatures,
depending on the time of year.
•
Never remove the key from the ignition while the vehicle is
moving. The steering l ock could engage suddenly, and you would

Driving
118•
Avoid high engine speeds, full throttle and extreme load condi-
tions until the engine has reached its normal operating tempera-
ture, otherwise this can damage the engine.For the sake of the environment
Do not warm up the engine by running it with the car stationary. You
should drive off immediately whenever possible. This will help avoid
unnecessary exhaust emissions.
Note
If the key should become stuck in the ignition lock, remove the top
part of the key and use it to lock the vehicle.Switching off the engine– Stop the vehicle.
– Automatic gearbox: Move the selector lever to position P or N.
– Press in the ignition key to switch off the engine.Emergency Off function
If necessary in an emergency, the engine can be switched off while
the vehicle is still moving. The engine will be switched off if you
press and hold the ignition key.
WARNING
•
Never switch off the engine until the vehicle is stationary.
•
The brake servo and the power steering system work only
when the engine is running. You need more strength to steer and
brake the vehicle when the engine is switched off. This would
mean a greater risk of accidents and serious injury, because you
cannot steer and brake in the normal manner.
Caution
If the engine has been working hard for a long time, there is a risk
of heat building up in the engine compartment after the engine has
been switched off; this could cause engine damage. For this reason,
you should leave the engine idling for about 2 minutes before
switching it off.
Note
After the engine is stopped the radiator fan may run on for up to
10 minutes, even if the ignition is switched off. The fan may also
start running again after some time if the coolant temperature rises
due to a build-up of heat, or if the engine is hot and the engine
compartment is heated up further by direct sunlight.Starting and stopping the engine

workshop without delay ⇒page 31 .
Note
•
The parking brake can be applied at any time - even when the
ignition is switched off. However, the ignition must be switched on
before the parking brake can be released.
•
Any slight noise which may be heard when the parking brake is
applied or released is quite normal and no cause for concern.
•
The parking brake runs an automatic test cycle at regular inter-
vals when the vehicle is parked. This may also cause a slight noise,
which is normal.
Parking
Please note the following points to ensure there is no risk
of the car rolling away accidentally after it is parked.Parking t he c ar
– Use the foot brake to stop the vehicle.
– Pull the switch to apply the parking brake.
– Automatic gearbox: Move the selector lever to P.
– Switch off the engine ⇒ .
– Manual gearbox: Engage the first gear.
When parking on slopes
– Turn the steering wheel so that the vehicle would roll into
the kerb if it did start to move accidentally.
WARNING
•

if you only intend to be gone for a short time. This is especially
important if children are left in the car. They might otherwise be
able to start the engine, releas e the parking brake or use power-
operated equipment such as the elec tric windows - this could lead
to injuries.
•
Do not leave anyone (especially chi ldren) in the vehicle when it
is locked. Locked doors could delay assistance in an emergency,
potentially putting lives at risk.

Driving
126The cruise control system allows you to drive at a constant speed of
30 km/h or higher.
A constant speed is maintained by adjusting the engine power or
braking the vehicle accordingly (while in cruise mode).
The cruise control system is set using the control lever ⇒page 125,
fig. 138. The indicator lamp lights up while the system is operating
⇒ fig. 139.
The cruise control system is automatically deactivated immediately
when you press the brake pedal.
On vehicles with a manual gearbox, the cruise control system will be
deactivated if the clutch is pressed for a long time.
WARNING
•
Always direct your full attention to the road, even when you are
using the cruise control system. It is always you who is respon-
sible for determining your speed and for keeping a safe distance
to the other vehicles on the road.
•
For safety reasons, the cruise control system must not be used
in city traffic, stop-go traffic, roads with a lot of bends or in diffi-
cult driving conditions (such as ice, fog, loose grit or gravel, heavy
rain, aquaplaning) - this could cause an accident!
•
When you take a turn-off, drive along a motorway exit lane or
pass through roadwork sections, please temporarily switch off the
cruise control system.
•
Please make sure you do not unintentionally rest your foot on
the accelerator - this will override the cruise control system which,
as a result, will not brake the vehicle.Caution
On vehicles with a manual gearbox: do not move the gear lever into
neutral without depressing the clutch when the cruise control
system is active. Otherwise the engine could rev up and be
damaged.
Note
•
On vehicles with a manual gearbox, the set speed cannot be
reached if the currently selected gear is too high or too low. Change
down to a lower gear when the engine no longer runs “smoothly” or
change up a gear to avoid overrevving the engine.
•
The brake lights come on when the system brakes the vehicle.
