Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
11-Keep the switch© pulled and depress the
accelerator. The parking brake stays applied
and prevents the vehicle from rolling back­
ward .
11-You can release the switch<®> once you are
su re that you a re develop ing enough for­
ward momentum at the wheels as you de­
press the accelerator.
D epending on the weight of the r ig (vehicle
and tra ile r) and the severi ty of the incl ine, you
may roll backwards as you start. Yo u can pre­
vent rolling backwards by holding the parking brake switch<®) p ulled out and acce lerating -
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.
11-In an emergency, pull the switch(®) and
contin ue to p ull it to slow your vehicle down
with the parking brake.
11-As soon as you release the switch (®) or ac-
ce lerate, the braking process stops.
If you pull the switch<®> and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy braking function is initiated. The vehicle is
braked at all four wheels by activating the hy­
draulic brake system. Th e brake performance
i s similar to making an emergency stop
~ &..
In order not to activate the emergency brak­
ing by m istake, an audible warning tone (buz­
ze r) sou nds when the switch C®> is pulled. As
soon as the switch(®) is released, or the accel­
e rator pedal is dep ressed, emergency b ra ki ng
stops.
_& WARNING
Emergency braking should only be used i n
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed .
On the ro ad 87
Using the parking b rake to pe rform emer­
gency brak ing will slow your vehicle down
as if you had made a full brake application.
The laws of physics cannot be suspended
even with ESC and i ts associated compo­
nents (ABS, ASR, EDL). In corners and
when road o r weathe r cond itions are bad,
a full brake appl ication can ca use the vehi­
cle to sk id or the re ar end to break away -
risking an acciden t.

position, the e ngine will also remain off if you
take your foot off the brake pedal. The engine
starts again when you select another se lector
lever position and take your foot off the brake
