WARNING
•
The function is supplementary driver
support intended to facilitate driving
and make it safer – it cannot handle all
situations in all traffic, weather and
road conditions.
•
•
Driver support functions are not a sub-
stitute for the driver's attention and
judgement. The driver is always
responsible for ensuring the car is
driven in a safe manner, at the appro-
priate speed, with an appropriate dis-
tance to other vehicles, and in accord-
ance with current traffic rules and reg-
ulations.
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 attempts to regulate the speed
smoothly. In situations that demand sudden
braking the driver must brake himself/herself.
This applies in cases of large speed differen-
ces 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.
Pilot Assist aims to 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.
Maintenance of driver support components
must only be performed at a workshop –
an authorised Volvo workshop is recom-
mended.
Round bends and when the road splits
Pilot Assist interacts with the driver, who
should therefore not wait for the steering
assistance from Pilot Assist but should always
be prepared to increase his/her own steering
input, especially in bends.
•
When the car approaches an exit or if the
lane splits, the driver should steer towards
the desired lane in order to specify the
desired direction to Pilot Assist.
Pilot Assist strives to keep the car in
the middle of the lane
When Pilot Assist helps to steer, it strives to
position the car in between the lane markings
and therefore it is recommended to let the car
find a good placement to achieve as smooth a
driving experience as possible. The driver
checks that the car is positioned safely in the
lane, and always has the ability to adjust the
position by making his/her own steering cor-
rections.
•
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

Hands on the steering wheel
In order for Pilot Assist to function, the driver’s
hands must be on the steering wheel.
If Pilot Assist detects that the
driver is not holding the
steering wheel, the driver is
prompted after a pause to
actively steer the car, via a
symbol and a text message.
If the driver's hands still cannot be detected
on the steering wheel after a few seconds, the
prompt to actively steer the car is repeated,
supplemented by an acoustic warning signal.
If Pilot Assist cannot detect the driver's hands
on the steering wheel after a further few sec-
onds, the warning signal becomes intensive
and the steering function is deactivated. Pilot
Assist must then be restarted using the steer-
ing wheel button
