Different time intervals can be
selected and are shown in the
display as 1–5 horizontal bars.
The greater the number of
bars, the longer the time inter-
val. One bar represents a time
interval of approximately
1 second; 5 bars is approximately
2.5 seconds. At low speeds, when the distance
to the vehicle ahead is short, ACC increases
the time interval slightly. In order to follow the
vehicle ahead as smoothly as possible, ACC
allows the time interval to vary considerably in
certain situations.
WARNING
•
Only use a time interval that is suitable
in current traffic conditions.
•
A short time interval gives the driver lim-
ited reaction time if an unexpected sit-
uation occurs in traffic.

time interval are shown while the setting is
