WARNING
If you depress the accelerator pedal with DSR
activated, then the set speed can be excee-
ded. Drive downhill with special care and
always keep in mind that DSR brakes the vehi-
cle as soon as you remove your foot from the
accelerator pedal. The vehicle may brake sud-
denly due to DSR intervening, depending on
the downhill gradient and the difference
between the current speed and the set speed.
You could lose control of the vehicle and
cause an accident.
For information about driving off-road, see
( page 166).
