Tips for driving with Distance Pilot
DISTRONIC
General notes
Pay particular attention in the following traffic
situations:
Cornering, entering and exiting a bend: the
R
ability of Distance Pilot DISTRONIC to detect
vehicles during cornering is limited. Your vehi-
cle may brake unexpectedly or late.
Driving on a different line: Distance Pilot
R
DISTRONIC may not detect vehicles which are
not driving in the middle of their lane. The dis-
tance to the vehicle in front will be too short.
Other vehicles changing lanes: Distance Pilot
R
DISTRONIC has not detected the vehicle cut-
ting in yet. The distance to this vehicle will be
too short.
Narrow vehicles: Distance Pilot DISTRONIC
R
has not yet detected the vehicle in front on
the edge of the road because of its narrow
width. The distance to the vehicle in front will
be too short.
Obstacles and stationary vehicles: Distance
R
Pilot DISTRONIC does not brake for obstacles
or stationary vehicles. If, for example, the
detected vehicle turns a corner and an obsta-
cle or stationary vehicle is then revealed, Dis-
tance Pilot DISTRONIC will not brake for
them.
Distance Pilot DISTRONIC may mistakenly
R
detect vehicles that are crossing your lane. If
you activate Distance Pilot DISTRONIC in the
following situations, the vehicle could pull
away unintentionally:
At traffic lights with crossing traffic, for
-
example.
With a vehicle ahead on the other side of an
-
intersection and the HOLD function active.
In such situations, brake if necessary. Distance
Pilot DISTRONIC will then be deactivated.
