_&. 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
r isk of slid ing.
- The stabilization function is limited when
offroad mode is switched on. The driving
wheels co uld spin and the vehicle could
swerve , especially on slick or slippery road
surfaces.
- T here is no vehicle stab ilizat ion when ESC/
ASR are switched off .
Hill descent assist
Hill descent assist makes it possible to drive
down a hill at a constant speed.
Fig. 155 Center console: hill descent ass ist button
.. To switch hill descent assist on, press the 1-
button. 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 from approximately 6 to 60%. The wheels w ill not lock
up because the ABS remains activated.
When hill descent assist is on, the speed your ve
hicle was traveling when it entered the hill is maintained. The assist begins shortly after you
start driv ing and continues up to approximately
19 mph (30 km/h). The driver can increase or de
crease the vehicle speed w ith in these limits by
pressing the accelerato r or brake pedal.
H owever, there must be enough traction. Hill de
scent assist
cannot function as expected, if for
150
example the hill is icy or if the surface is loose
~ & .
Active regulat ion of a speed up to approximately
19 mph (30 km/h) is signaled in the instrument
cluster by an indicator light •. T he indicator
light turns on when in the ready mode.
II.
The system does not work at speeds above ap
proximately 19 mph (30 km/h). The system is
then in ready-mode . This is indicated by the LED
in the button turning on.
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 hill angle is at least approximately 6%
_&. 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 phys ics. Your driving style
must always be adapted to the current road
and traffic cond itions .
- Hill descent assist may not be able to hold
your vehicle at a constant speed under all
conditions while driving on a hill (for exam
ple if ground under the vehicle is loose).
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first 250 mi (400 km). They
must be "broken in" first. However, you can com
pensate for the slightly reduced braking force by
pressing f irmly on the brake pedal. Avo id heavy
braking during the break-in period.
Wear
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions .
This is especially true if you are driv ing frequent ly
