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.

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

tally.
However, the electro-mechanical pa rking brake also offers a number
of convenience and safety features in addition to the functions of a
normal handbrake. When driving away
•
The parking brake auto release function releases the parking
brake automatically when you wish to start moving ⇒page 122,
“Driving away from a standstill”.
•
When driving away on a gradient, the parking brake auto release
function prevents the vehicle from rolling back unintentionally. The
braking force of the parking brake is only released when there is
enough power at the wheels to make the vehicle move in the desired
direction.
Emergency braking function
An emergency braking function enables you to stop the vehicle even
if the conventional foot brake should fail to work ⇒page 123,
“Emergency braking function”.

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
•
Always take the key with you when leaving the vehicle – even
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 away from a standstill
The parking brake auto release function releases the
parking brake automatically when you wish to start
moving.Applying the parking brake when stopping
– Pull the switch to apply the parking brake.
Releasing the parking brake when driving away
– Drive off in the normal way: the parking brake will be released automatically and the vehicle will start moving.On vehicles with automatic gearbox, you can apply the parking
brake when stopping at traffic lights, etc. Then you do not have to
hold the car with the footbrake, as the parking brake will stop it
creeping forward while a gear is engaged in the automatic transmis-
sion. When you drive off in the normal way, the parking brake will be
released automatically and the vehicle will start moving.
Driving away on a slope
When driving away on a gradient, the parking brake auto release
function prevents the vehicle from rolling back unintentionally. The

⇒ .
– As soon as you accelerate as normal, the parking brake will automatically be released and the vehicle will start
moving.
Pa rking the c ar
– Press and hold the brake pedal ⇒.
– Apply the parking brake.
– Press and hold the interlock button, move the selector lever to P and release the interlock button.Your vehicle is equipped with the hill hold assist function which
makes it easier to drive away on a slope. The system is activated
when you press and hold the brake pedal for a few seconds. When
you release the brake pedal the braking force will be maintained for
a moment in order to prevent the vehicle rolling back when you drive
away.
The engine c an only be started when the selector lever is at P or N.
On level ground it is sufficient to move the selector lever to P. On a
gradient the parking brake should be applied first and the selector
lever should be moved to P. This reduces the load on the locking
mechanism and makes it easier to move the selector lever out of
position P.
WARNING
•
Do not press the accelerator while selecting a gear with the
vehicle stationary and the engine running, as this could cause an
accident.
•
Please note that some power will still be transmitted when you
stop temporarily with the selector lever in position D, S or R. For this reason, to avoid ri
sking an accident, appl y the footbrake firmly
when stopping to prevent the vehicle rolling away.
•
Never move the selector lever to R or P when driving, as this
could cause an accident.
Applies to vehicles: with multitronic®Selector lever positions
This section covers all the selector lever positions.The current selector lever position is shown in the instrument
cluster display.
