Driving and Driving Safety
Adaptive Cruise Control
Adaptive cruise control maintains any selected
speed between approx. 20–100 mph
(30–160 km/h) when driving on open roads
without you having to use the accelerator.
If a vehicle traveling ahead of you in the same lane
is detected as driving slower than the selected
speed, adaptive cruise control will automatically
maintain a set distance from the vehicle in front.
Adaptive cruise control slows your vehicle down if
the distance to the vehicle ahead becomes too
short and accelerates your vehicle if the distance
increases.
If the current traffic situation does not allow you to
drive safely at a constant speed and with sufficient
distance to the vehicle in front, using the adaptive
cruise control can cause accidents.
f
Do not use the adaptive cruise control in heavy
traffic, in city traffic, on twisting roads or under
unfavorable road conditions (e.g. wintry or wet
conditions, varying road surfaces).
f
Observe all local and national speed limits.
Adaptive cruise control will not detect stationary
or slowly moving vehicles, pedestrians, objects on
the road, oncoming vehicles in the same lane or
cross traffic.
f
You must pay attention to your vehicle’s
position in relation to other objects and
intervene as needed to ensure safe driving.
f
Always keep the direction of travel in your field
of view.
Radar sensor
Adaptive cruise control uses a radar sensor
located in the middle of the front apron (
arrow
).
Information
f
Always keep the radar sensor clean and free of
ice and snow to ensure that it is fully functional.
For car care instructions:
f
Please see the chapter “CAR CARE
INSTRUCTIONS” on page 255.
This equipment complies with FCC radiation
exposure limits set forth for an uncontrolled
environment. This equipment should be installed
and operated with minimum distance of 8 in.
(20 cm) between the radiator and your body.
This transmitter must not be co-located or
operating in conjunction with any other antenna or
transmitter.
Radar sensor vision can be impaired by rain,
snow, ice or heavy spray. Vehicles in front will not
be detected properly or may not be detected
at all.
f
Do not use adaptive cruise control under these
conditions.
Warning message
Adaptive cruise control can be deactivated
automatically if the radar sensor is very dirty or
iced up, obstructed, in unfavorable weather
conditions (heavy rain) or when driving through
tunnels.
The message “ACC/PAS unavailable” will appear
on the multi-purpose display of the instrument
panel.
For information on warning messages on the
multi-purpose display:
