WARNING
Eye injury may occur if any of the following
points are not followed:
•It is essential that all pertinent instruc-
tions be followed when handling laser
instruments. Testing, repairing, remov-
ing, adjusting and/or replacing any
components in the laser sensor may
only be done by a trained and qualified
Volvo service technician.
•Do not remove the laser sensor (includ-
ing removal of the lenses). A laser sen-
sor that has been removed belongs to
laser class 3B according to standard
IEC 60825-1. Devices in laser class 3B
present a risk of injury to the eyes.
•The laser sensor’s connector must be
disconnected before the sensor is
removed from the windshield.
•The laser sensor must be mounted in
place on the windshield before con-
necting the sensor’s connector.
•Do not view the laser sensor (which
emits spreading, invisible laser beams)
with optical instruments from a distance
of less than 4 inches (100 mm).

* Option/accessory, for more information, see Introduction.169 Function
Function overview
Visual warning signal, collision risk
Radar sensor
Camera
Collision WarningThe radar sensor and the camera work
together to detect a pedestrian, stationary
vehicles and vehicles that are moving in the
same direction as your vehicle. If there is a risk
of collision with a vehicle or a pedestrian, the
driver is alerted by a flashing red warning light
and an audible warning signal. Collision warn-
ing is active at speeds above 3 mph (4 km/h).
Brake SupportIf the risk of collision continues to increase after
the collision warning has been given, Brake
Support is activated. Brake Support prepares
the brake system to react quickly, and the
brakes are applied slightly. This may be expe-
rienced as a light tug.
If the brakes are applied quickly, full braking
effect will be provided. Brake Support also
increases brake force if the system determines
that the driver has not applied adequate pres-
sure on the brake pedal.
Auto-brakeIf a collision is imminent and the driver has not
applied the brakes or begun to steer around the
vehicle or pedestrian, the auto-brake function
is activated without the driver pressing the
brake pedal. Full brake force is applied to help
reduce the vehicle’s speed when the collision
occurs or limited brake force is applied if this
is sufficient to avoid the collision.
NOTE
The auto-brake and brake support functions
are always on and cannot be turned off.
Operation
Settings are made by pressing MY CAR on the
center console control panel and using the
menus displayed.
On and offTo switch Collision Warning on or off, press MY
CAR on the center console control panel and
go to Settings
Car settingsCollision
warning
On/Off. If Collision Warning is on,
the system will perform a self-test each time
the engine is started by briefly illuminating the
warning light. See page 129 for more informa-
tion about the menu system.
When the engine is switched on, the Collision
Warning setting that was being used when it
was switched off will be the default setting.
Activating/deactivating warning signalsThe collision warning system’s visual signals
are activated automatically when the engine is
started if the collision warning system is
switched on.

WARNING
•In certain situations, the system cannot
provide warnings or warnings may be
delayed if traffic conditions or other
external factors make it impossible for
the radar sensor or camera to detect a
pedestrian or a vehicle ahead.
•Warnings may not be provided if the
distance to the vehicle ahead is short,
or if movements of the steering wheel/
brake pedal are great, such as during
active driving.
•The sensor system has a limited range
for pedestrians and provides warnings
and braking effect most effectively at
speeds up to 30 mph (50 km/h). For sta-
tionary or slow-moving vehicles, the
system functions best if your vehicle’s
speed is below approximately 45 mph
(70 km/h).
•Warnings for stationary or slow-moving
vehicles may not be provided in dark
conditions or in poor visibility.
The Collision Warning system uses the same
radar sensors as Adaptive Cruise Control. For
more information on the radar sensor and its
limitations, see page 155.
NOTE
If warnings are given too frequently, the
warning distance can be reduced (see
page 170). This causes the system to pro-
vide later warnings, which decreases the
total number of warnings provided.
WARNING
•The system is not activated at speeds
under approx. 2 mph (4 km/h). There-
fore, it will not brake your vehicle if you
approach a vehicle ahead at very low
speed, such as when parking.
•The driver's actions always have high-
est priority and override the Collision
Warning system. This means that the
system will not intervene in situations
where the driver is actively steering,
braking or pressing the accelerator
pedal, even if a collision is imminent.
•When Auto-brake has prevented a col-
lision with a stationary object, your vehi-
cle will remain at a standstill for approx.
1.5 seconds. If your vehicle has been
braked for a moving vehicle ahead, your
vehicle's speed will be reduced to the
same speed as that vehicle's.
The camera’s limitationsThe camera is used by Collision Warning with
Auto-brake, Driver Alert Control (see
page 175), and Lane Departure Warning (see
page 178).
NOTE
•To help protect the camera in very hot
conditions, it may be temporarily
switched off for approximately 15
minutes after the engine has been
started.
•Keep the section of the windshield in
front of the camera clean and free of ice,
snow, or condensation.

Park assist*
04

* Option/accessory, for more information, see Introduction.181 Introduction
The park assist system is designed to assist
you when driving into parking spaces, garages,
etc. It utilizes four ultrasound sensors located
in one or both bumpers to measure the dis-
tance to a vehicle, object, or a person who may
be close to the front or rear of your vehicle. An
audible signal and symbols in the audio sys-
tem’s display indicate the distance to the
object.
This system is available in the rear bumper
only, or in both the front and rear bumpers.
WARNING
Park Assist is an information system, NOT a
safety system. This system is designed to
be a supplementary aid when parking the
vehicle. It is not, however, intended to
replace the driver's attention and judge-
ment.
Function
Park assist button
The system is activated automatically when the
vehicle is started. The indicator light in the but-
ton in the center console illuminates when the
system is on.
•The front park assist system is active from
the time the engine is started until the vehi-
cle exceeds a speed of approximately
10 mph (15 km/h). It is also active when the
vehicle is backing up.
•Rear park assist is active when the engine
is running and reverse gear has been
selected.
Activating/deactivatingThe system is activated automatically when the
vehicle is started.

Press the Park assist button on the center
console to temporarily deactivate the sys-
tem(s).
> The indicator light in the button will go
out when the system has been deacti-
vated.
Park assist will be automatically reactivated the
next time the engine is started, or if the button
is pressed (the indicator light in the button will
illuminate).
NOTE
Park assist is disengaged automatically
when the parking brake is applied.

Signals from the park assist system
View in the display (warning for objects front left/
right rear)
Visual indicatorThe audio system’s display gives an overview
of the vehicle’s position in relation to a
detected object.
The marked sectors in the display indicate that
one or more of the sensors has detected an
object. The closer the car symbol comes to a
sector, the closer the vehicle is to the object.
If the infotainment system is switched off, the
park assist system will not be able to provide a
visual indicator. An audible signal will still be
provided.
Audible signalThe Park Assist system uses an intermittent
tone that pulses faster as you come close to an
object, and becomes constant when you are
within approximately 1 ft (30 cm) of an object
in front of or behind the vehicle. If there are
objects within this distance both behind and in
front of the vehicle, the tone alternates
between front and rear speakers.
NOTE
The level of the audible signal can be low-
ered/raised with the infotainment volume
control. The level can also be set in the MY
CAR menu system, see page 129.
If the volume of another source from the audio
system is high, this will be automatically low-
ered.
Rear park assist
The distance monitored behind the vehicle is
approximately 5 ft (1.5 m). The audible signal
comes from the rear speakers.
The system must be deactivated when towing
a trailer, carrying bicycles in a rear-mounted
carrier, etc, which could trigger the rear park
assist system's sensors.
NOTE
Rear park assist is deactivated automati-
cally when towing a trailer if Volvo genuine
trailer wiring is used.
