WARNING•
The radar sensor has a limited field of
vision. In some situations, it may detect a
vehicle later than expected or not detect
other vehicles at all.
• The radar sensor cannot cover all driving
situations and traffic, weather and road
conditions.
• The driver is responsible for maintaining a
safe distance and speed and must inter-
vene if the various driver support systems
do not maintain a suitable speed or suita-
ble distance to the vehicle ahead.
• Maintenance of radar sensor components
may only be performed by a trained and
qualified Volvo technician.
• Strong sunlight, reflections from the road
surface, strong lighting contrasts or using
sunglasses may make the warning light in
the windshield difficult to see. Poor
weather or winding roads can affect the
radar sensor's capacity to detect vehicles
ahead.
• A vehicle's size (e.g., a motorcycle) can
also affect the radar sensor's capacity to
detect another vehicle. This may result in
the warning light illuminating at a shorter
distance than the one that has been set
or not illuminating at all. •
High speeds may also result in the warn-
ing light illuminating at a shorter distance
than the one that has been set due to
limitations in the radar sensor's range.
NOTE The function uses the vehicle's radar unit,
which has some general limitations – see the
section "Radar unit limitations".

Distance Alert* (p. 291) Adaptive Cruise Control*
Adaptive Cruise Control (ACC 41
) helps the
driver maintain a constant speed with a set time
interval to the vehicle ahead.
Adaptive Cruise Control helps provide a more
relaxed driving experience on long trips on high-
ways or long, straight roads with even traffic
flows. The camera/radar sensor measures the distance to the
vehicle ahead
42
.
The driver sets a speed and a time interval to the
vehicle ahead. If the camera/radar sensor detects
a slower-moving vehicle ahead, your vehicle's
speed will be automatically adapted according to
the set time interval to that vehicle. When there
are no longer slower-moving vehicles ahead, the
vehicle will return to the set speed.

WARNING
•
The Adaptive Cruise Control function is
supplementary driver support intended to
facilitate driving and help make it safer –
it cannot handle all situations in all traffic,
weather and road conditions.
• The driver is advised to read all sections
in the Owner's Manual about this function
to learn of its limitations, which the driver
must be aware of before using the func-
tion (see the link list at the end of this
article).
• Adaptive Cruise Control is not a substi-
tute for the driver's attention and judg-
ment. The driver is always responsible for
ensuring the vehicle is driven in a safe
manner, at the appropriate speed, with an
appropriate distance to other vehicles,
and in accordance with current traffic
rules and regulations.
NOTE Depending on market, this function may be
either Standard or Optional.
Adaptive Cruise Control regulates speed by
accelerating and braking. It is normal for the brakes to emit a slight sound when they are
being used to adjust speed.
Adaptive Cruise Control always attempts to regu-
late speed smoothly. The driver must apply the
brakes in situations requiring immediate braking.
For example, when there are great differences in
speed between vehicles or if the vehicle ahead
brakes suddenly. Due to limitations in the radar
sensor, braking may occur unexpectedly or not at
all.
Adaptive Cruise Control is designed to follow a
vehicle ahead in the same lane and maintain a
time interval to that vehicle set by the driver. If the
radar sensor does not detect a vehicle ahead, it
will instead maintain the speed set by the driver.
This will also happen if the speed of the vehicle
ahead exceeds the set speed for your vehicle.
• Adaptive Cruise Control can follow another
vehicle at speeds from a standstill up to
200 km/h (125 mph).
WARNING •
Adaptive Cruise Control is not a collision
avoidance system. The driver is always
responsible and must intervene if the sys-
tem fails to detect a vehicle ahead.
• Adaptive Cruise Control does not brake
for people or animals and does not brake
for small vehicles, such as bikes and
motorcycles. Similarly, it does not brake
for low trailers, oncoming, slow-moving or
stationary vehicles and objects.
• Do not use Adaptive Cruise Control in
demanding situations, such as in city traf-
fic, at intersections, on slippery surfaces,
with a lot of water or slush on the road, in
heavy rain/snow, in poor visibility, on
winding roads, or on on/off ramps.
CAUTION Maintenance of Adaptive Cruise Control com-
ponents may only be performed by a work-
shop – an authorized Volvo workshop is rec-
ommended.

Adaptive Cruise Control utilizes approx. 40% of
the vehicle's braking capacity. If a situation
requires more braking force than the Adaptive
Cruise Control can provide, and if the driver does
not apply the brakes, a warning light and audible
warning signal will be activated to alert the driver
that immediate action is required.
NOTE Visual warnings on the windshield may be dif-
ficult to notice in cases of strong sunlight,
reflections, extreme light contrasts, or if the
driver is wearing sunglasses or is not looking
straight ahead.
WARNING Adaptive Cruise Control only issues a warning
for vehicles detected by its radar unit – thus, a
warning may come after a delay or not at all.
• Never wait for a warning. Apply the
brakes when necessary.

WARNING
•
The Pilot Assist function is supplementary
driver support intended to facilitate driv-
ing and help make it safer – it cannot
handle all situations in all traffic, weather
and road conditions.
• The driver is advised to read all sections
in the Owner's Manual about this function
to learn of its limitations, which the driver
must be aware of before using the func-
tion (see the link list at the end of this
article).
• Pilot Assist should only be used if there
are clear lane lines painted on each side
of the lane. All other use will increase the
risk of contact with nearby obstacles that
cannot be detected by the functions.
• Pilot Assist is not a substitute for the driv-
er's attention and judgment. The driver is
always responsible for ensuring the vehi-
cle is driven in a safe manner, at the
proper position within the lane, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.NOTE Depending on market, this function may be
either Standard or Optional.
Pilot Assist regulates speed by accelerating and
braking. It is normal for the brakes to emit a slight
sound when they are being used to adjust speed.
Pilot Assist attempts to smoothly regulate speed.
The driver must apply the brakes in situations
requiring immediate braking. For example, when
there are great differences in speed between
vehicles or if the vehicle ahead brakes suddenly.
Due to limitations in the camera and radar sen-
sor, braking may occur unexpectedly or not at all.
Pilot Assist is designed to follow a vehicle ahead
in the same lane and maintain a time interval to
that vehicle set by the driver. If the radar sensor
does not detect a vehicle ahead, it will instead
maintain the speed set by the driver. This will also
happen if the speed of the vehicle ahead
exceeds the set speed for your vehicle.
• Pilot Assist can follow another vehicle at
speeds from a standstill up to 200 km/h
(125 mph).
• Pilot Assist can provide steering assistance
from near-stationary speeds up to 140 km/h
(87 mph).WARNING •
Pilot Assist is not a collision avoidance
system. The driver must intervene if the
system fails to detect a vehicle ahead.
• Pilot Assist does not brake for people,
animals, objects, small vehicles (e.g.
cycles and motorcycles), low trailers as
well as oncoming, slow or stationary vehi-
cles.
• Do not use Pilot Assist in demanding sit-
uations, such as in city traffic, at intersec-
tions, on slippery surfaces, with a lot of
water or slush on the road, in heavy rain/
snow, in poor visibility, on winding roads,
on highway on- or off-ramps, or with a
trailer connected to the vehicle.
CAUTION Maintenance of the integrated components in
Pilot Assist may only be performed by a work-
shop – an authorized Volvo workshop is rec-
ommended.
In curves and forks in the roadPilot Assist is designed to interact with the driver.
The driver should never wait for steering assis-
tance from Pilot Assist, but instead should always
be ready to increase his or her own steering
efforts, particularly in curves.
