Your vehicle is equipped with an electrome­
chanical parking brake. The parking brake is
designed to prevent the vehicle from rolling unintentionally and replaces the hand brake.
In addit ion to the normal functions of a tradi­
tiona l hand brake, the electromechanical
parking brake provides vario us convenience
and safety functions .
When starting from rest
-The integral start ing assist helps you when
driving by automatically re leasing the park­
i ng brake
i=:> page 86, Starting from rest.
- When start ing on inclines , the starting as-
sist prevents the vehicle from unintentiona l-
ly rolling back. The braking force of the
parking brake is not re leased until sufficient

E mergency brake function
An emergency brake ensures t hat the vehicle
can be slowed down even if the
normal brakes
fail
c::> page 87, Emergency braking .
&_ WARNING
Do not press the accelerator peda l inadver ­
tently if the vehicle is stationary but the
engine is running and a gear is selected.
Otherw ise the vehicle will start to move
immediately and could result in a crash.
- If the parking brake is applied with the
ignition switched off, the indicator lights
in the sw itch and . (USA models) .
(Canada models) in the instrument clus­
ter will go out after a certain per iod of
time.
- Occas iona l noises when the park ing
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
regular intervals. Any assoc iated noises
are no rma l.

the curb if it begins to move.
&_ WARNING
- When you leave your veh icle - even if on­
ly b riefly - always take the ignition key
with you. This applies par tic u larly when
children remain in the veh icle . Otherw ise
the chi ldren could start the engine, re-
'

tr ica l equipment (e.g. power windows).
There is the r isk of an accident.
- When the veh icle is locked, no one - par­
ticularly not children should rema in in
the vehicle. Locked doors make it more difficult for emergency workers to get in­

Stopping and applying par king brake
.. Pull the sw itch<®> to apply the parking
brake.
Sta rting and automaticall y rel easing the

When stopping at a traffic signal or stopping in city traffic, the parking brake can be ap­
plied . The vehicle does not have to be held
with the footbrake. The parking brake elimi­ nates the tendency to creep w ith a dr ive range
engaged . As soon as you drive off as usual,
t h e pa rking brake is re leased automatically
and the vehicle s tarts to move .
Sta rting on slopes
When starting on inclines, the starting assist
prevents the vehicle from u nintent ionally roll­
i ng back. The braking force of the parki ng
brake is not re leased unti l suffic ient d riving
force has been built up at the w heels.
(D Tips
Fo r safety reasons, the pa rking brake is re­
l eased automatically on ly when the d riv ­
er's safety belt is engaged in the buckle.
