▷
The maximum speed when reversing is
limited to approx. 6 mph/10 km/h.
A warning is issued at a speed of approx.
4 mph/7 km/h.
If the maximum speed is exceeded, the
function is interrupted.
Different influences can lead to side deviations
when driving the stored distance covered in re-
verse. For example, this includes the following
factors:
▷ Steering movements when the vehicle is
stationary while storing the distance cov-
ered.
▷ The speed is not adapted to the distance
covered.
▷ Certain road characteristics such as gradi-
ents, inclines or slippery road surface.
▷ Greatly deviating conditions when storing
and driving the route, for instance other
tires or changed ambient conditions like
weather.
▷ Back-up Assistant Professional: for
changed light conditions.
