Setting The Time Interval For The Adaptive Cruise Control - Volvo XC 90 Owner's Manual

DRIVER SUPPORT
Setting the time interval for the
Adaptive cruise control*
The Adaptive cruise control (Adaptive Cruise
Control -ACC) can be set to different time inter-
vals.
Different time intervals to the
vehicle in front can be selected
and shown in the driver display
as 1-5 horizontal lines - the
more lines the longer the time
interval. One line represents
about 1 second to the vehicle
in front, 5 lines represents about 3 seconds.
The same symbol is also shown when the Dis-
tance Warning function is activated.
NOTE
When the symbol in the driver display shows
two cars, ACC is following the vehicle in front
at a pre-set time interval.
When only one car is shown, there is no vehi-
cle within a reasonable distance ahead.

Distance indicator
– Press the steering wheel button (1) or (2) to
increase or decrease the time interval.
> The distance indicator (3) shows the cur-
rent time interval.
The adaptive cruise control allows the time inter-
val to vary significantly in certain situations in
order to allow the car to follow the vehicle in front
smoothly and comfortably. At low speed, when
the distances are short, the adaptive cruise con-
trol increases the time interval slightly.
Note that a short time interval only allows the
driver a short time to react and take action if any
unforeseen problem should arise.
NOTE
Only use the time intervals permitted by local
traffic regulations.
If the adaptive cruise control does not appear
to react when activated, this may be because
the time distance to the vehicle in front is pre-
venting an increase in speed.
The higher the speed the longer the calcula-
ted distance in metres for a given time inter-
val.
