On th e road
Startin g and automati cally releasing the
park ing brake
.. When you start to drive as usua l, the park -
ing brake is automatically re leased and your
vehicle begins to move.
When stopping at a traffic signa l or stopping
in city traffic on vehicles with an automatic
transmission,
the park ing brake can be ap-
plied. The vehicle does not have to be held
with the footbrake. The park ing brake elimi-
nates the tendency to creep with a drive range
engaged . As soon as you dr ive off as usual,
the park ing brake is released automatically
and the veh icle starts to move .
Starting on slopes
When starting on incline s, the start ing ass ist
prevents the vehicle from unintentionally
roll-
ing back. The braking force of the parking
brake is not released until sufficient dr iving
fo rce has been bu ilt up at the whee ls.

Tips
For safety reasons, the park ing brake is re-
leased automatically only when the dr iv-
er 's sa fety belt is engaged in the bu ckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
.. Keep the switch @ ¢

pulled
and depress the acce le rator . The park ing
brake stays applied and prevents the vehicle
from roll ing backward.
.. You can release the switch @ once you are
sure that you are developing enough driving
force at the wheels by depressing the accel -
erator.
Depending on the weight of the rig (vehicle
and trai ler) and the severity of the incline, you
may roll backwards as you start . You can pre-
vent roll ing backwards by holding the parking
brake switch @ pulled out and accelerating -
just as you would when starting on a hill with
a conventional hand brake .
Emergency braking
In the event that the conventional brake sys-
tem fails or locks.
.. In an emergency, pull the switch @
¢

and continue t o pull it to
slow your vehicle down with the parking
brake .
.. As soon as you re lease the switch @ or ac-
celerate, t he bra king pro cess stops.
If you pull the switch @ and hold it above a
speed of about 5 mph (8 km/h), the emergen-
cy bra king funct ion is initiated . The vehicle is
braked at all fou r whee ls by activating the hy-
draulic brake sys t em. The brake performance
is similar to making an emergency stop ¢ ,& .
In order not to act ivate the eme rgency brak-
ing by mis t ake, an audib le warning tone (buz-
zer) so unds when the switch @ is pulled. As
soon as the switch @ is released, or the acce l-
erator pedal is depressed, emergency braking
stops.
A
WARNING
,-
Emergency braking should only be used in
an emergency, when the normal foot brake
has fa iled or the brake pedal is obstructed .
Using the par king brake to pe rform eme r-
gency braking will slow your veh icle down
as if you had made a full brake application.
The laws of phys ics cannot be suspended
even with ESC and its associated compo -
nents (ABS, ASR, EDS). In corners and
when road or weathe r cond itions are bad,
a full brake application can ca use the vehi -
cle to sk id or the rear end to break away-
risking an accident.
