Pilot Assist*
Pilot Assist can help the driver to drive the
car between the lane's side markings as well
as to maintain an even speed, combined with
a preselected time interval to the vehicle
ahead.
Get to know Pilot Assist
The camera and radar unit measures the distance to
the vehicle ahead and detects side markings.

about all of the function's applications and lim-
itations in order to safely use all of the advan-
tages.
The Pilot Assist function is primarily intended
for use on motorways and similar major roads
where it can contribute to more comfortable
driving and a more relaxed driving experience.
The driver selects the desired speed and a
time interval to the vehicle ahead. Pilot Assist
scans the distance to the vehicle ahead and
the lane's side markings on the road surface
using the camera unit. The preset time interval
is maintained with automatic speed adjust-
ment whilst the steering assistance helps to
position the car in the lane.
Pilot Assist regulates the speed with accelera-
tion and braking. It is normal for the brakes to
emit a low sound when they are being used to
adjust the speed.
Pilot Assist strives to:
regulate the speed smoothly. In situations
•
that demand sudden braking the driver
must brake himself/herself. This applies in
cases of large speed differences or if the
car in front brakes suddenly. Due to the
limitations of the camera and radar unit,
braking may come unexpectedly or not at
all.
follow the vehicle ahead in the same lane
•
at a time interval set by the driver. If the
radar unit cannot see any vehicle in front
then the car will instead maintain the
speed set and stored by the driver. This
also takes place if the speed of the vehicle
ahead increases and exceeds the stored
speed.
Position of the car in the lane
When Pilot Assist helps to steer, it attempts to
place the car halfway between the visible lane
markings. For a smoother drive, it is a good
idea to allow the car to find a good position.
The driver can always adjust the position him/
herself by increasing the steering input. It is
important that the driver checks to make sure
the car is positioned safely in the lane.
If Pilot Assist does not position the car in an
appropriate way in the lane, it is recom-
mended to turn Pilot Assist off or switch to
adaptive cruise control*.
