Use cruise control only if road and traffic con-
dition sm ake it appropriate to maintain as teady
speed for ap rolonged period. You can stor ea ny
road speed above 20 mph (30 km/h).
Important safet yn otesIf you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take int oa ccoun tt he road, traffic and
weather conditions. Cruise control is only an
aid. You are responsible for the distance to the
vehicle in front, for vehicle speed, for brakin gi n
good time and for staying in lane.
Do not use cruise control: R
in road and traffic condition sw hich do not
allow you to maintain ac onstan ts peed e.g. in
heavy traffic or on winding roads R
on slippery road surfaces .B raking or accel-
eratin gc ould cause the drive wheels to lose

To avoid damage to the vehicle, deactivate
Distance Pilot DISTRONIC and the HOLD

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 eP ilot 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: R
in road and traffic conditions which do not
allow you to maintain ac onstant speed, e.g. in
heavy traffic or on winding roads R
on slippery road surfaces. Brakin gora ccel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid R
when 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 ad ifferent line.
In particular, the detection of obstacles can be
impaired if: R
there is dirt on the sensors or anything else
coverin gt he sensorsR
there is snow or heavy rain R
there is interferenc ebyo ther radar sourcesR
there are stron gr adar 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: R
be too high if you are driving in af ilter lane or
an exit lane R
be so high when driving in the right-hand lane
that you overtak ev ehicles in the left-hand
