Volvo XC90: Driver support / Setting time interval to the vehicle ahead
The time interval to the vehicle ahead can be set for the functions Adaptive
Cruise Control*, Pilot Assist* and Distance Alert*.
Different time intervals to the
vehicle ahead can be selected and are shown in the instrument panel as 1–5 horizontal
bars. The more bars, the longer the time interval. One bar represents an interval
of approx. 1 second to the vehicle ahead. 5 bars represents approx. 3 seconds.
NOTE
When the symbol in the instrument panel shows a vehicle and a steering
wheel, Pilot Assist follows a vehicle ahead at a preset time interval.
When only a steering wheel is shown, there is no vehicle ahead within a
reasonable distance.
NOTE
When the symbol in the instrument panel shows two vehicles, Adaptive Cruise
Control is following the vehicle ahead at a preset time interval.
When only one vehicle is shown, there is no vehicle ahead within a reasonable
distance.

Controls for setting a time interval.
Reduce the time interval
Increase the time interval
Distance indicator
- Press the (1) or (2) button to decrease or increase the time interval.
- The distance indicator (3) shows the current time interval.
In order to help your vehicle follow the vehicle ahead as smoothly and comfortably
as possible, Adaptive Cruise Control allows the time interval to vary noticeably
in certain situations. At low speeds, when the distance to the vehicle ahead is
short, Adaptive Cruise Control increases the time interval slightly.
NOTE
- The greater the vehicles' speed, the greater the distance between
them for a set time interval.
- Only use the time intervals permitted by local traffic regulations.
- If driver support does not seem to respond with a speed increase when
activated, it may be because the time interval to the vehicle ahead is shorter
than the set time interval.
WARNING
- Only use a time interval suitable for the current traffic conditions.
- The driver should be aware that short time intervals give them limited
time to react and act to any unforeseen traffic situation.
* Option/accessory.
It is possible to adjust set speeds for the cruise control, Adaptive Cruise
Control* and Pilot Assist* functions.
