DSR supports you when driving downhill. DSR
maintains a set speed for you on downhill gradi-
ents by applying the brakes as required. Maintain-
ing the speed is dependent on the road surface
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:
R
If the vehicle is stationary, or its speed is less
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.
R
If you drive faster than 11 mph (18 km/h) o -
road, DSR switches to standby mode. DSR
remains activated, but does not brake automat-
ically.
R
If you drive downhill slower than 11 mph
(18 km/h), DSR sets the speed to the previ-
ously set speed.
R
If you drive faster than 28 mph (45 km/h),
DSR switches o automatically.

You can activate DSR when the vehicle is station-

Press the upper section of switch

#
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 main-
tains the stored speed on the downhill gradient
and brakes automatically.
When DSR is activated and the vehicle pulls away,
accelerates or brakes on an incline, the speed set
corresponds 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).
