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 Detection (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 techni-
cian as soon as possible. The radar sen-
sor may only function partially (or not at
all) if it is damaged or is not securely fas-
tened 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 vehicles
ahead is impeded:
•
if the radar sensor is obstructed and cannot
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 significantly
different from your own speed.

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.
