If the crash-responsive EASY-EXIT feature is trig-
gered in an accident, the steering column will
move upwards when the driver's door is opened.
This occurs irrespective of the position of the

To avoid damage to the vehicle, deactivate
Distance Pilot DISTRONIC and the HOLD
function in the following or similar situations:
Rwhen towing the vehicle
Rin the car wash
If you fail to adapt your driving style, Distance
Pilot DISTRONIC can neither reduce the risk of
an accident nor override the laws of physics.
Distance Pilot DISTRONIC cannot take into
account road, weather or traffic conditions. Dis-
tanc ePilot DISTRONIC is only an aid. You are
responsible for the distance to the vehicle in
front,f or vehicle speed, for braking in good time
and for staying in your lane.
Do not use Distance Pilot DISTRONIC:
Rin road and traffic conditions which do not
allow you to maintain aconstant speed, e.g. in
heavy traffic or on winding roads
Ron slippery road surfaces. Brakingora ccel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
Distance Pilot DISTRONIC may not detect nar-
row vehicles driving in front,e .g. motorcycles, or
vehicles driving on adifferent line.
In particular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
coveringt he sensors
Rthere is snow or heavy rain
Rthere is interferenc ebyother radar sources
Rthere are stron gradar reflections, for exam-
ple, in parking garages
If Distance Pilot DISTRONIC no longer detect sa
vehicle in front,D istance Pilot DISTRONIC may
unexpectedly accelerate to the speed stored.
This speed may:
Rbe too high if you are driving in afilter lane or
an exit lane
Rbe so high when driving in the right-hand lane that you overtak evehicles in the left-hand
lane
Rbe so high when driving in the left-hand lane
