Important safety notes
G
WARNING
If the speed driven and the set speed deviate
and you activate DSR on a slippery road sur-
face, the wheels may lose traction. This
increases the risk of skidding and having an
accident.
Before switching DSR on, please take into
consideration the road surface and the differ-
ence between driving speed and the set
speed.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor override
the laws of physics. DSR cannot take account of
road, weather and traffic conditions. DSR is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
You are always responsible for keeping control
of the vehicle and for assessing whether the
downhill gradient can be managed. DSR may not
always be able to keep to the set speed, depend-
ing on road surface and tyre conditions. Select a
set speed suitable for the prevailing conditions
and when necessary, apply the brakes manually.

The
Ã
DSR symbol appears in the multi-
function display.
You can only activate DSR when driving at
speeds below 40 km/h.
If the current vehicle speed is too high, the
Ã
DSR symbol appears in the multifunction display
with the
Max. speed 40 km/h

message.
If you have activated DSR and then change drive
programs, DSR is deactivated. If you switch
between the offroad and offroad plus drive pro-
grams, DSR remains activated.

On vehicles with the Offroad Engineering pack-
age, if you select a different drive program, DSR
is also deactivated. If you switch between the
offroad programs, DSR remains activated.
Changing the set speed
X
To increase or reduce the set speed in
1 km/h increments: briefly press the cruise
control lever up
:
for a higher set speed or
down
;
for a lower set speed.
The set speed appears in the multifunction
display with the
Ã
DSR symbol.
When DSR is activated, you can change the set
speed to a value between 2 km/h and 18 km/h.
i
The DSR set speed is always changed in
1 km/h increments. This is regardless of
whether you press the cruise control lever to
or beyond the pressure point.
