Radar sensor
The radar sensor is designed to help detect
cars or larger vehicles driving in the same
direction as your vehicle, in the same lane.
The radar sensor and its limitations
In addition to being used by the Adaptive
Cruise Control (ACC), the radar sensor is also
used by Distance Alert (see Distance Alert –
introduction (p. 198)) and Collision Warning
with Full Auto-brake and Pedestrian Detec-
tion (see Collision warning – introduction
(p. 209)).
WARNING
•
If there is visible damage to the front
grille or you suspect that the radar
sensor may be damaged in any way,
contact a trained and qualified Volvo
service technician as soon as possible.
The radar sensor may only function
partially (or not at all) if it is damaged
or is not securely fastened in place.
•
Accessories or other objects, such as
extra headlights, must not be installed
in front of the grille.
•
Modification of the radar sensor could
make its use illegal.
The radar sensor's capacity to detect vehi-
cles ahead is impeded:
•
if the radar sensor is obstructed and can-
not detect other vehicles, for example in
heavy rain, or if snow or other objects are
obscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor
clean.
•
if the speed of vehicles ahead is signifi-
cantly different from your own speed.

Adaptive Cruise Control – limitations
The ACC cannot cover all driving situations
and traffic, weather and road conditions.
Situations where ACC may not function
optimally
WARNING
•
The radar sensor has a limited field of
vision. In some situations it may detect
a vehicle later than expected or not
detect other vehicles at all.
•
If ACC is not functioning properly,
cruise control will also be disabled.
