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 parking 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 32.
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, release the parking brake or use power-
operated equipment such as the electric windows - this could lead
to injuries.
•
Do not leave anyone (especially children) in the vehicle when it
is locked. Locked doors could delay assistance in an emergency,
potentially putting lives at risk.

 in the instrument cluster
will light up.
A constant speed is maintained by adjusting the engine power or
braking the vehicle accordingly.
WARNING
•
Always direct your full attention to the road, even when you are
using the cruise control system. It is always the driver who is
responsible for determining the 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-and-go traffic, roads with a lot of bends or in
difficult 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.Note
•
Vehicles with 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 if the engine is no longer running smoothly or change
up a gear to avoid overrevving the engine.
•
The brake lights come on when the system brakes the vehicle.
Applies to vehicles: with cruise control systemAdjusting the speed– Push the lever up towards or down towards
⇒page 125, fig. 134 in order to increase or reduce the
cruising speed setting.
