brake pedal or the accelerator pedal and press
the switch @ at the same time to release the
parking brake . The indicator lights in the switch
and . (USA models)/ . (Canada models) in
the instrument cluster go out .
Your vehicle is equipped with an electromechani­
cal park ing brake. The parking brake is designed
to prevent the vehicle from rolling un intent ional­
ly and replaces the ha nd b rake .
In add ition to the normal functions of a trad i­
t ional ha nd brake, the electromechanical parking
brake prov ides va rious conven ience and safety
funct ions.
When starting from rest
- The integral starting assist helps you when
driving by automatically releas ing the parking
brake ~
page 86 , Starting from rest.
- When start ing on inclines, the starting assist
prevents the veh icle from unintentionally roll­
ing back . T he brak ing force of the park ing brake
is not re leased unt il sufficient dr iving force has
been bu ilt up at the whee ls.

A WARNING
If a gear or a drive range (automatic transmis­
s ion) is engaged wi th the vehicle stationa ry
a nd the engine runn ing, you must in no in­
stance acce lera te or release the clutch* care ­
l essly. Otherwise the vehicle wi ll sta rt to
move immediately- risk of an accident.

Driving
- Occasional noises when the parking brake is
applied and released are normal and are not
a cause for concern.
- When the vehicle is parked, the parking
brake goes through a self-test cycle at regu­
lar intervals. Any associated noises are nor­
mal.
Parking
.,. Press the brake pedal to stop the vehicle .
.,. Pull the switch @¢
page 85, fig. 100 to set
the parking brake.
.,. Automatic transmission: Move the selector lev-
er to P.
.. 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
.. Pull the switch @¢ page 85, fig. 100 to apply
the parking brake.
86
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 .

-If you accidenta lly select N while driving,
take your foot off the accelerator pedal im­
mediately and wa it for the engine to slow
down to idle before select ing 0/5 .
