Distance indicator
Press the steering wheel button (1) or (2) to
–

rent time interval.
The adaptive cruise control allows the time inter-
val 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 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 in an
unexpected traffic situation.
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 vehi-
cle 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.

tions.
