Warning!
If the accelerator pedal is depressed while
the Downhill Speed Regulation (DSR) is
activated, the vehicle can drive faster than
the programmed set speed. You should
therefore drive downhill with particular
caution as it could otherwise lead to an
accident and/or serious injury to you or
others. Keep in mind that as soon as you
remove your foot from the accelerator
pedal with the DSR switched on, the DSR
will start regulating the vehicle’s speed
including use of brakes if required.
Depending on the programmed set speed,
actual vehicle speed and gradient, the DSR
can cause the vehicle to slow down rapidly.
Sudden and unexpected deceleration can
result in loss of vehicle control, causing an
accident and/or serious personal injury to
you and others.
Switching on the DSR
The DSR can only be switched on if the vehicle
speed is below 18 mph (Canada: 30 km/h).
