DRIVER SUPPORT
Limitations for overtaking
assistance with adaptive cruise
control
The overtaking assistance function may have lim-
ited functionality in certain situations.
WARNING
When using the Overtaking Assistance Sys-
tem, the driver should be aware that there
may be undesired acceleration if the condi-
tions suddenly change.
Some situations should therefore be avoided,
such as if:
the car is approaching an exit for turn-of
•
that is in the same direction as overtaking
would normally occur.
the vehicle ahead slows down before the
•
driver's car has crossed over into the
overtaking lane.
the traffic in the overtaking lane slows
•
down.
a right-hand drive car is driven in a county
•
with left-hand traffic (or vice versa).
Situations of this kind can be avoided by tempo-
48
rarily setting ACC in the standby mode.

Changing target with adaptive
cruise control
In combination with automatic gearbox, the
49
adaptive cruise control (ACC ) has functionality
for change of target at certain speeds.
Change of target
If the target vehicle in front suddenly turns then there
may be stationary traffic in front.
When adaptive cruise control is following another
vehicle at speeds below 30 km/h (20 mph) and
changes target from a moving to a stationary
vehicle, the adaptive cruise control will slow down
for the stationary vehicle.
