DSR (Downhill Speed Regulation)

Notes on DSR
If you fail to adapt your driving style or you are
inattentive, DSR can neither reduce the risk of
accident nor override the laws of physics. DSR
cannot take road, weather and traffic conditions
into account. DSR is only an aid. You are respon‐
sible for a safe distance to the vehicle in front, for
vehicle speed and for braking in good time.
DSR supports you when driving downhill. DSR
maintains a set speed for you on downhill gradi‐
ents by applying the brakes as required. Main‐
taining the speed is dependent on the road sur‐
face conditions and the downhill gradient and
cannot therefore be guaranteed in all situations.
You can set the speed depending on the gear
range to between 2 mph (4 km/h) and 11 mph
(18 km/h) using the brake and accelerator pedals
or the rocker switch on the steering wheel.
DSR automatically controls in the following situa‐
tions:
If the vehicle is stationary, or its speed is less
R
than 2 mph (4 km/h) , the speed is set to
2 mph (4 km/h) or it is set to the minimum
speed for the respective gear range.
If you drive faster than 11 mph (18 km/h) off-
R
road, DSR switches to standby mode. DSR
remains activated, but does not brake auto‐
matically.
If you drive downhill slower than 11 mph
R
(18 km/h), DSR sets the speed to the previ‐
ously set speed.
If you drive faster than 28 mph (45 km/h),
R
DSR switches off automatically.
Activating/deactivating DSR
Activating DSR
You can activate DSR when the vehicle is station‐
ary or moving.
Press the upper section of switch 1.
#
Brake or accelerate the vehicle to the desired
#
speed between 2 mph (4 km/h) and 11 mph
(18 km/h).
Release the brake or accelerator pedal.
#
The current speed is stored. When stationary,
2 mph (4 km/h) or the minimum possible
speed for each gear range is stored. DSR
maintains the stored speed on the downhill
gradient and brakes automatically.
When DSR is activated and the vehicle pulls
away, accelerates or brakes, the speed set corre‐
sponds to the speed at which the accelerator or
brake pedal is released or the rocker switch is
pressed during DSR regulation. This is only the
case if you are not driving faster than 11 mph
(18 km/h).

DSR is activated:
R
DSR and the set speed appear in the sta‐
-
tus area of the on-board computer.
DSR is activated, but is not intervening:

(18 km/h) and 28 mph (45 km/h).
DSR and the speed 11 mph (18 km/h)
-
appear in the status area of the on-board
computer.
DSR is in standby mode.
