DSR (Downhill Speed Regulation)
▌Function of DSR
DSR is an aid to assist you when driving downhill.
It keeps the speed of travel at the selected target
speed. The steeper the downhill gradient, the
greater the DSR braking effect on the vehicle. On
flat stretches of road and uphill gradients, the
DSR brakes the vehicle minimally or not at all.
When DSR is activated and the transmission is in
position h, k or i, DSR controls the driving
speed. The target speed can be set to a value
between 1 mph (2 km/h) and 11 mph (18 km/h).
By braking or accelerating, you can drive at a
higher or lower speed than the target speed at
any time.
If you drive faster than 28 mph (45 km/h) or
change the drive program (except in F), DSR
switches off automatically. The î
sage will then appear on the instrument display.
The status indicator on the instrument display
goes out. You also hear a warning tone.
▌Information on DSR
& WARNING Risk of skidding and accident
when DSR is activated on slippery road
surfaces
If the driven speed and the target speed differ,
the wheels may lose traction.
Take into account the road surface and
#
the difference between the driving speed
and target speed before activating DSR.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognize
dangers ( page 176).
/
You are always responsible for keeping control of
the vehicle and for assessing whether the downhill
gradient can be negotiated. Depending on road
surface and tires, DSR may not always be able to
keep to the target speed. Select a target speed
suitable for the environmental conditions and also
apply the brakes yourself if required.
