_&. WARNING
You should only switch offroad mode on or
switch ESC/ ASR off if your driving abilities
and the traff ic conditions perm it. There is a
risk of slid ing.
- The stabilization function is limited when
offroad mode is switched on. The driving
wheels could spin and the vehicle could
swerve, especially on slick or slippery road
surfaces.
- There is no vehicle stab ilizat ion when ESC/
ASR are switch ed off .
Hill descent assist
Applies to: vehicles with hill hold assist
Hill descent assist makes it possible to drive
down a hill at a constant speed.
Fig. 100 Center console: hill descent ass ist button
.,. To switch the hill descent assist on, press the
~
button in the center console c:> fig. 100. The
LED in the button turns on.
.,. Press the button again to switch it off. The LED
in the button turns off.
Hill descent assist brakes all four wheels auto-
matically in order to limit speed when driving ei-
ther forward or reverse on hills with a grade up to
approx imately 50%.
When hill descent assist is on, the speed your ve-
hicle was traveling when it entered the hill is
maintained. It is only possible to switch on the
assist when driving slower than 37 mph (60 km/
h). The assist occurs br iefly after start ing to drive
up to approximately 19 mph (30 km/h). The dr iv-
er can increase or decrease the vehicle speed
94
within these limits by pressing the accelerator or
brake pedal.
However, there must be enough tract ion. Hill de-
scent assist
cannot function as expect ed, if fo r
example the hill is icy or if the surface is loose
c:>,& .
Active assistance at a specific speed up to about
19 mph (30 km/h) is shown in the instrument
cluster through a blinking indicator light •. The
indicator light shines continuously when in the
ready mode.
The system does not work at speeds between 19
and 37 mph (30 and 60 km/h). The system is
then in ready-mode . This is indicated by the LED
in the button turning on. The system automat i-
cally switched off when you drive faster than 37
mph (60 km/h) . The LED will also turn off in this
scenario.
Hill descent assist is automatically activated un-
der the following conditions:
- the LED in the button turns on,
- the vehicle speed is lower than 19 mph (30 km/
h),
- the incline angle is at least around 10%.
_&. WARNING
- Always adapt your speed to the weather,
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking risks, because this increases the risk
of an accident .
-
- The hill descent assist system cannot over-
come the laws of physics. Your driving style
must always be adapted to the current road
and traffic conditions.
- Hill descent assist may not be able to hold
your vehicle at a constant speed under all
conditions while dr iving on a hill (for exam-
ple if ground under the vehicle is loose).
Brakes
New brake pads
New brake pads do not achieve thei r full braking
effect during the first 250 mi (400 km). They
must be "broken in" first. However, you can ..,.
