Radar sensor
The function of the radar sensor is to detect cars
or larger vehicles in the same direction, in the
same lane.
The radar sensor is used by the following func-
tions:
•
Distance Warning*
•
Adaptive cruise control*
•
Collision Warning System with Auto Brake
and Cyclist and Pedestrian Detection*
IMPORTANT
In the event of visible damage to the car's
grille, or if you suspect that the radar sensor
may be damaged:
•
Contact a workshop - an authorised
Volvo workshop is recommended.
The function may completely or partially dis-
appear - or malfunction - if the grille, the
radar sensor or its bracket is damaged or has
loosened.
Modification of the radar sensor could result in it
being illegal to use.

Radar sensor - limitations
A radar sensor (p. 219) has certain limitations -
due to its limited field of vision for example.
The capacity of the adaptive cruise control to
detect a vehicle in front is significantly reduced if:
•
the speed of vehicles in front is significantly
different from your own speed
•
its radar sensor becomes blocked - e.g. in
heavy rain or slush, or if other objects have
collected in front of the radar sensor.
NOTE
Keep the area in front of the radar sensor
clean - see subheading "Maintenance"
(p. 235).
Field of vision
The radar sensor has a limited field of vision. In
some situations another vehicle is not detected,
or the detection is made later than expected.
