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.
When the symbol in the driver display shows a car and a steering wheel, Pilot Assist follows a vehicle in front at a preset time gap.
When only one steering wheel is shown, there is no vehicle within a reasonable distance ahead.
Control for time intervalNOTE: The illustration is schematic - details may vary depending on car model..
Press the steering wheel button (1) or (2) to increase or decrease the time interval.
The distance indicator (3) shows the current time interval.
In order to follow the vehicle ahead in a smooth and comfortable way, Pilot Assist allows the time interval to vary noticeably in certain conditions. For example, at low speed, when the distances become short, Pilot Assist increases the time interval slightly.
- The higher the speed the longer the calculated distance in metres for a given 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 window to the vehicle ahead is shorter than the set time window.
- Only use a time window that suits the current traffic conditions.
- The driver should be aware that short time windows limit the amount of time available to react and take action in an unexpected traffic situation.
Select how Pilot Assist shall maintain the distance* to the vehicle ahead
The driver can select different driving styles for how Pilot Assist should maintain the preset time interval to the vehicle ahead. Selection is made via the drive mode control DRIVE MODE.
Select one of the following options:
- Eco - Pilot Assist focuses on optimal fuel economy, which means longer time interval to the vehicle ahead.
- Comfort - Pilot Assist focuses on following the set time interval to the vehicle ahead as smoothly as possible.
- Dynamic - Pilot Assist focuses on following the set time interval to the vehicle ahead more closely, which in certain cases may mean heavier acceleration and braking.
