Steering lock
The steering locks when you remove the ignition
key. The locked steering helps prevent vehicle
theft.
Emergency off
If it is necessary in unusual circumstances, the
engine can be switched off while the vehicle is
moving. The engine will be switched off if you
press on the key for an extended period .
A WARNING
-Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake if necessary . Be ­
cause you cannot steer and brake as you
usually would, this could lead to crashes
and serious injuries .
- For safety reasons, you should always park
your vehicle with the selector lever in P .
Otherwise, the vehicle could inadvertently
roll away.
- The radiator fan can continue to run for up
to 10 minutes even after you have turned
off the engine and removed the ignition key .
The radiator fan can also turn on again if the
engine coolant heats up because of intense
sunlight or heat build-up in the engine com­
partment .
- Always take the key with you whenever you
leave your vehicle . Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury .
- Never leave children or persons requiring as­
sistance unattended in the vehicle. The
doors can be locked using the remote trans­
mitter, preventing people from escaping
from the vehicle on their own in the event of
an emergency. Depending on the time of
year, people inside the vehicle can be ex­
posed to very high or very low tempera­
tures.

.. Turn the engine off¢.&, .
.. Manual transmission: Shift into 1st gear.
.. When on inclines or declines, turn the steering
wheel so that the vehicle will roll into the curb
if it begins to move.
A WARNING
-
-When you leave your vehicle -even if only
briefly -always remove the ignition key. This
applies particularly when children remain in
the vehicle. Otherwise the children could
start the engine, release the parking brake
or operate electrical equipment (e.g. power
windows). There is the risk of an accident.
- When the vehicle is locked, no one -particu­
larly not children should remain in the vehi­
cle. Locked doors make it more difficult for
emergency workers to get into the vehicle -
putting lives at risk.
Starting from rest
The starting assist function ensures that the
parking broke is released automatically upon
starting .
Stopping and applying parking brake

Starting and automatically releasing the parking brake
.. When you start to drive as usual, the parking
brake is automatically released and your vehicle
begins to move.
When stopping at a traffic signal or stopping in city traffic on vehicles with an automatic trans­
mission, the parking brake can be applied. The
vehicle does not have to be held with the foot­ brake. The parking brake eliminates the tendency
to creep with a drive range engaged . As soon as
you drive off as usual, the parking brake is re­ leased automatically and the vehicle starts to
move .
Starting on slopes
When starting on inclines, the starting assist pre ­
vents the vehicle from unintentionally rolling back. The braking force of the parking brake is
not released until sufficient driving force has
been built up at the wheels.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an in­
cline, do the following:
.. Keep the switch @¢ page 85, fig . 100 pulled
and depress the accelerator. The parking brake
stays applied and prevents the vehicle from
rolling backward.
.,. You can release the switch @once you are sure
that you are developing enough driving force at
the wheels by depressing the accelerator.
Depending on the weight of the rig (vehicle and
trailer) and the severity of the incline, you may
roll backwards as you start. You can prevent roll­
ing backwards by holding the parking brake
switch @pulled out and accelerating -just as
you would when starting on a hill with a conven­
tional hand brake .
