Different time intervals to the

bars. The greater the number of
bars, the longer the time inter-
val.
One bar between the vehicles represents a time
interval of approximately 1 second; 5 bars is
approximately 3 seconds.
The same symbol appears if Adaptive Cruise
Control is activated.

The greater the vehicles' speed, the
greater the
distance
between them for a

limitations
Distance Alert uses the same radar sensor as
Adaptive Cruise Control
*
and has several limita-
tions.
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.
•
The radar sensor cannot cover all driving
situations and traffic, weather and road
conditions.
•
The driver is responsible for maintaining a
safe distance and speed and must inter-
vene if the various driver support systems
do not maintain a suitable speed or suita-
ble distance to the vehicle ahead.
•
Maintenance of radar sensor components
may only be performed by a trained and
qualified Volvo technician.
•
Strong sunlight, reflections from the road
surface, strong lighting contrasts or using
sunglasses may make the warning light in
the windshield difficult to see.
