Different time intervals to the vehicle ahead can be selected and are shown in the instrument panel as 1–5 horizontal bars. The greater the number of bars, the longer the time interval. One bar between the vehicles represents a time interval of approximately 1 second; 5 bars is approximately 3 seconds.
The same symbol appears if Distance Alert is activated.
- If the symbol shows two vehicle's, ACC is actively following the vehicle ahead (a target vehicle).
- If only one vehicle is displayed, ACC is not actively following another vehicle.

Distance/time indicator
Press buttons (1) or (2) to reduce or increase the time interval.
The distance/time indicator (3) shows the current time interval.
In order to follow the vehicle ahead as smoothly as possible, ACC allows the time interval to vary considerably in certain situations. At low speeds, when the distance to the vehicle ahead is short, ACC increases the time interval slightly.
- If ACC does not seem to react when it is put in active mode, this may be because the set time interval to the vehicle ahead does not allow an increase in speed.
- The higher the speed, the greater the distance to the vehicle ahead for a given time interval.
- Only use time intervals permitted by local traffic regulations.
Warning
- Only use a time interval that is suitable in current traffic conditions.
- A short time interval gives the driver limited reaction time if an unexpected situation occurs in traffic.
