Overtaking assistance with Adaptive
Cruise Control
50
Adaptive cruise control (ACC ) can assist the
driver when overtaking other vehicles.
How overtaking assistance works
When ACC is following another vehicle and the
driver indicates the intention to overtake by acti-
51
vating the direction indicator , adaptive cruise
control helps by accelerating the vehicle towards
the vehicle in front before the driver's vehicle
reaches the overtaking lane.
The function then delays reducing speed in order
to avoid premature braking when the driver's car
is approaching a slower vehicle.
The function remains active until the driver's vehi-
cle has cleared the overtaken vehicle.
WARNING
Be aware that this function can be activated
in more situations than during overtaking, e.g.
when a direction indicator is used to indicate
a change of lane or exit to another road – the
car will then accelerate briefly.

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-
52
rarily setting ACC in the standby mode.
