page 138)
•
ACC has kept the vehicle at a standstill
for more than 2 minutes

The radar sensor and its limitations
In addition to being used by ACC, the radar
sensor is also used by Distance Alert (see
page 155) and Collision Warning with Full
Auto-brake and Pedestrian Detection (see
page 164). This sensor is designed to detect
cars or larger vehicles driving in the same
direction as your vehicle, in the same lane.
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.

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.
