S90 Twin Engine Setting a time interval for Pilot Assist

P5-1646-Pilot Assist symbol Avstånd + Styrning UTAN nr

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.

P5-Icon red circle 1 — Controls for setting a time interval1.

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 follow the vehicle ahead as smoothly as possible, Pilot Assist allows the time interval to vary considerably in certain situations. For example, at low speeds and short distances to the vehicle ahead, Pilot Assist 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 Pilot Assist 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 Pilot Assist should maintain distance* to the vehicle ahead

The driver can choose different drive modes to determine how Pilot Assist should maintain a time interval to the vehicle ahead. Settings are made using the DRIVE MODE controls.

Select one of the following:

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