Setting Adaptive Cruise Control time intervals

Updated 2020-03-19

Adaptive Cruise Control (ACC1) can be set to various time intervals to the vehicle ahead.

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.

The same symbol appears when the Distance Alert function is activated.

Note

When the symbol in the instrument panel shows two vehicles, ACC 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.

P5-1519-xc90H-ACC avstånd — Controls for setting a time interval2.

P5-Icon red circle 1 — Controls for setting a time interval2.

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 the Adaptive Cruise Control 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.

Setting how ACC should maintain distance* to the vehicle ahead

A number of different settings can be made for how Adaptive Cruise Control should maintain a time interval to the vehicle ahead. Settings are made using the DRIVE MODE controls.

Select one of the following:

Eco - ACC will focus on providing optimal fuel economy, which will increase the time interval to the vehicle ahead.
Comfort - ACC will focus on following the set time interval to the vehicle ahead as smoothly as possible.
Dynamic - ACC will focus on following the set time interval to the vehicle ahead more exactly, which could mean faster acceleration and heavier braking.
