Driving
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 brake pedal. The parking brake elimi-
nates the tendency to creep when a selector
lever position is engaged . As soon as you
press the accelerator pedal, the parking brake
releases automatically and the vehicle starts
to move.
Starting on slopes
When starting on inclines, the hill start assist
prevents the vehicle from unintentionally
roll-
ing back. The braking force of the parking
brake is not released until sufficient driving
force has been built up at the wheels.

Tips
For safety reasons, the park ing brake is re-
leased automatically only when the driv-
er 's safety belt is fastened and the driver 's
door is locked.
Emergency braking function
This is used if the convention brake system
fails or locks up.

To brake your vehicle in an emergency, pull
the @ switch

and hold it
pulled.
~
As soon as you release the @ switch or ac-
celerate, the braking process stops.
Pulling and holding the @ switch while driv-
ing at a speed of about 2 mph (3 km/h) or
higher initiates the emergency braking func-
tion. The vehicle is braked at all four wheels
by activating the braking hydraulics. The brake
performance is similar to heavy braking. ¢ .&
To help prevent activating the emergency
braking by mistake, an audible warning tone
(buzzer) sounds when the @ switch is pulled.
Emergency braking stops as soon as the @
switch is released or the accelerator pedal is
pressed.
A
WARNING
Emergency braking should only be used in
an emergency, when the normal brake
pedal has failed or the brake pedal is ob-
structed . During emergency braking, your
vehicle will brake similar to heavy braking .
ESC and the associated components (ABS,
ASR, EDL) cannot overcome the laws of
physics. In corners and when road or
weather conditions are bad, a full brake
application can cause the vehicle to skid or
the rear end to break away, which increas-
es the risk of an accident.
Hill hold
Applies to vehicles: wit h Hill Hold
Hill hold makes it easier to start on hills.
Requirement: The driver door must be closed
and the engine must be running.
The system is activated when the brake pedal
is pressed while the vehicle is stationary.
To prevent the vehicle from rolling back when
starting, the brake power is held for a brief
moment after releasing the brake pedal. Dur-
ing this time, you can easily begin to move
your vehicle.
A
WARNING
......_
- The intelligent technology of Hill Hold
cannot overcome the limitations im-
posed by natural physical laws. The in-
creased comfort offered by Hill Hold
should not cause you to take safety risks .
- Hill Hold cannot hold the vehicle in all
hill start situations (for example, if the
ground is slippery or icy).
- If you do not begin moving immediately
after releasing the brake pedal, the vehi-
cle could begin to roll backward under
certain circumstances.
Press the brake
pedal or set the parking brake immedi-
ately.
- If the engine "stalls", press the brake
pedal or set the parking brake immedi-
ately.
