Limitations for overtaking
assistance with Pilot Assist
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-
rarily setting Pilot Assist in the standby mode.

Change the target with Pilot Assist
In combination with automatic gearbox, Pilot
Assist 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 Pilot Assist is following another vehicle at
speeds below 30 km/h (20 mph) and changes
target from a moving to a stationary vehicle, Pilot
Assist will slow down for the stationary vehicle.
WARNING
When Pilot Assist is following another vehicle
at speeds in excess of approx. 30 km/h
(20 mph) and the target is changed from a
moving vehicle to a stationary vehicle, Pilot
Assist will ignore the stationary vehicle and
instead accelerate to the stored speed.
•
The driver must then intervene him/
herself and brake.
DRIVER SUPPORT
Automatic standby mode with change of
target
Pilot Assist is disengaged and set in standby
mode:
•
when the speed is below 5 km/h (3 mph)
and Pilot Assist is uncertain whether the tar-
get object is a stationary vehicle or some
other object, e.g. a speed bump.
•
when the speed is below 5 km/h (3 mph)
and the vehicle in front turns off so the Pilot
Assist no longer has a vehicle to follow.
