Changing a time interval
Controls for setting a time interval
Reduce the time interval
Increase the time interval
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 dis-
tance 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 lim-
ited reaction time if an unexpected situa-
tion occurs in traffic.

Passing Assistance with Adaptive
Cruise Control or Pilot Assist-2
ACC or Pilot Assist can assist the driver when
passing other vehicles.
How passing assistance works
When ACC or Pilot Assist is following another
vehicle and the driver indicates that he/she is
about to pass that vehicle by using the left turn
signal, ACC or Pilot Assist will begin accelerating
toward the vehicle ahead before your vehicle has
moved into the passing lane.
The function will then delay a speed reduction to
avoid early braking as your vehicle approaches
the slower-moving vehicle.
The function is active until your vehicle has
passed the other vehicle.
WARNING
Be aware that this function may be activated
in situations other than when passing a vehi-
cle, such as if the turn signal is used to indi-
cate a lane change or to indicate a turn. The
vehicle will accelerate briefly.
