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 Distance Warning function is activated.
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 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.
The adaptive cruise control allows the time interval 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 control 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 the adaptive cruise control 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 if an unexpected traffic situation arises.
Select how ACC shall maintain the distance* to the vehicle ahead
The driver can select different driving styles for how the Adaptive cruise control 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 - ACC focuses on optimal fuel economy, which means longer time interval to the vehicle ahead.
- Comfort - ACC focuses on following the set time interval to the vehicle ahead as smoothly as possible.
- Dynamic - ACC focuses on following the set time interval to the vehicle ahead more closely, which in certain cases may mean heavier acceleration and braking.
