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 20 mph (Canada: 30 km/h).
