WARNING
The ACC does not react when approaching a stationary obstacle, such as
■
traffic jams, vehicle breakdowns or vehicles waiting at a traffic light.
The ACC does not respond to crossing or oncoming objects.
■
If the ACC does not decelerate fast enough, immediately apply the vehi-
■
cle's foot brake.
WARNING
For safety reasons, do not use the ACC under the following conditions.
When driving in turning lanes, motorway exits or construction sites, to
■
avoid an unwanted acceleration to the stored speed.
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
When driving around "sharp" bends.
■
When riding on a steep gradient / high slope.
■
CAUTION
The control may automatically switch off when some brake assist systems (e.g.
ESC) intervene, when the maximum permissible engine speed is exceeded, etc.
Note
The ACC is designed primarily for use on motorways.
■
The ACC reduces the speed by automatically releasing the accelerator or by
■
means of a braking procedure as appropriate. If the brakes are used for an au-
tomatic speed reduction at any moments, then the brake light illuminates.
In case of failure of more than one brake light on the vehicle or on the elec-
■
trically connected trailer, the ACC becomes unavailable.
Radar sensor

Mounting location of the radar
sensor

Read and observe and
The radar sensor » Fig. 144 (From here on referred to as sensor) is used to as-
sess the traffic situation in front of the vehicle.
The sensor can distinguish objects by radiating and receiving electromagnetic
waves.
The sensor function may be impaired in the events of one of the following.
›
The sensor is covered by mud, snow or debris, for example.
›
The sensor or its immediate surroundings are covered by other objects, for
example, a sticker is attached.
›
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
If the sensor is dirty or does not have "visibility" for any other reason, the fol-
lowing message appears in the instrument cluster display
WARNING
If you suspect that the sensor is damaged, deactivate the ACC. Have the
■
sensor checked by a specialist garage.
The sensor can become misaligned by collisions or by damage to the front
■
of the vehicle, the wheel arch or the underside of the vehicle. This can lead
to an impairment of the ACC function - risk of accidents! Have the sensor
checked by a specialist garage.
The area in front of and around the sensor must not be covered with
■
stickers, additional lights or similar items. This can lead to impaired function
of the sensor - risk of accidents!
WARNING
The sensor may not be able to distinguish all objects correctly under certain
circumstances. You should therefore not use ACC in the following cases -
risk of accidents!
When driving through places where metal objects (such as metal build-
■
ings, railroad tracks, etc.) can be found.
When driving through very divided and enclosed spaces (such as large-ca-
■
pacity garages, car ferries, tunnels and the like.).
CAUTION
Remove the snow with a brush and the ice with a solvent-free de-icer.
