Volvo S60 Twin Engine Owner's Manual page 299

Adaptive Cruise Control regulates the speed
with acceleration and braking. It is normal for
the brakes to emit a low sound when they are
being used to adjust the speed.
The adaptive cruise control aims to control the
speed in a smooth way. In situations that
demand sudden braking the driver must brake
himself/herself. This applies in cases of large
speed differences or if the vehicle in front
brakes suddenly. Due to the limitations of the
radar unit, braking may come unexpectedly or
not at all.
The adaptive cruise control aims to follow the
vehicle ahead in the same lane at a time inter-
val set by the driver. If the radar unit cannot
see any vehicle in front then the car will
instead maintain the speed set and stored by
the driver. This also takes place if the speed of
the vehicle ahead increases and exceeds the
stored speed.
IMPORTANT
Maintenance of driver support components
must only be performed at a workshop –
an authorised Volvo workshop is recom-
mended.
