Setting time interval for Adaptive
Cruise Control
The Adaptive Cruise Control (ACC
set to different time intervals.
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 Dis-
tance Warning function is activated.
NOTE
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 vehi-
cle within a reasonable distance ahead.

The adaptive cruise control allows the time inter-

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 con-
trol increases the time interval slightly.

NOTE
•
The higher the speed the longer the cal-
culated 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.
WARNING
•
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.
