The number of bars indicating
the selected time interval are
shown while the setting is
being made and for several
seconds afterward. A smaller
version of the symbol is then
shown to the right in the dis-
play. The same symbol is displayed when
Adaptive Cruise Control (ACC) is activated.
NOTE
•The higher your vehicle’s speed, the
greater the distance to the vehicle
ahead, measured in feet (meters), for a
given time interval.
•The set time interval is also used by
Adaptive Cruise Control, see page 163.
WARNING
Only use a time interval that is suitable in
current traffic conditions.
Limitations
Distance Alert uses the same radar sensor
used by Adaptive Cruise Control and the Col-
lision Warning system. See page 165 for more
information on the radar sensor’s limitations.
NOTE
Strong sunlight, reflections, extreme light
contrasts, the use of sunglasses, or if the
driver is not looking straight ahead may
make the visual warning signal in the wind-
shield difficult to see.
WARNING
•Bad weather or winding roads may
affect the radar sensor’s capacity to
detect vehicles ahead.
•The size of the vehicle ahead, such as a
motorcycle, may also make it difficult to
detect. This may result in the warning
light illuminating at a shorter distance
than the one that has been set, or that
the light will not come on at all.

Collision warning with Auto-brake*
04

* Option/accessory, for more information, see Introduction.173 Introduction
Collision Warning with Auto-brake is designed
to assist the driver if there is a risk of a collision
with a vehicle ahead that is at a standstill or
moving in the same direction as your vehicle.
Collision Warning consists of the following
three functions:
•Collision Warning warns the driver of a
potential collision situation.
•Brake Support helps the driver brake effi-
ciently in a critical situation.
•Auto-brake brakes the vehicle automati-
cally if a collision cannot be avoided. Auto-
brake cannot prevent a collision but can
reduce the speed at which a collision
occurs.
WARNING
The auto-brake function cannot prevent a
collision but instead is intended to reduce
speed at the moment of impact. For full
braking effect, driver must apply the brakes.
WARNING
•Collision Warning does not work in all
driving, traffic, weather and road condi-
tions. It does not react to vehicles not
traveling in the same direction as your
vehicle.
•The collision warning system is not
designed to detect pedestrians.
•Warnings are only provided when the
risk of collision is high. The "Function"
section provides information about lim-
itations that the driver must be aware of
before using Collision Warning.
•The auto-brake function can help
reduce the speed at impact but the
driver should always apply the brakes
for the best possible braking effect,
even if auto-brake is actively applying
the brakes.
•Never wait for a collision warning. This
system is designed to be a supplemen-
tary driving aid. It is not, however,
intended to replace the driver's atten-
tion and judgement. The driver is
responsible for maintaining a safe dis-
tance and speed, even when the colli-
sion warning system is in use.
•Maintenance of the Collision Warning
system's components must only be
performed by a trained and qualified
Volvo technician.

Function overview
Visual warning signal, collision risk
Radar sensor
Camera
Collision WarningThe radar sensor and the camera work
together to detect stationary vehicles and vehi-
cles that are moving in the same direction as
your vehicle. If there is a risk of collision, the
driver is alerted by a flashing red warning light
and an audible warning signal. Collision warn-
ing is active at speeds above 5 mph (7 km/h).

Collision warning with Auto-brake*
04
174* Option/accessory, for more information, see Introduction.
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, even if pressure on the
brake pedal is light.
Auto-brakeIf a collision is imminent and the driver has not
applied the brakes or begun to steer around the
vehicle, the auto-brake function is activated
without the driver pressing the brake pedal.
Limited brake force is applied to reduce the
vehicle’s speed when the collision occurs. The
driver must apply the brakes for full braking
effect.
WARNING
The auto-brake function cannot prevent a
collision but instead is intended to reduce
speed at the moment of impact. For full
braking effect, driver must apply the brakes.
NOTE
The auto-brake function is always on and
cannot be turned off.
Operation
Some settings are controlled from the center
console via a menu system.
On and offTo switch Collision Warning on or off, go into
the menu Car settings
Collision
warning settings and select On or Off. When
the engine is started, the setting that was
selected when it was switched off will be used.
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 audible and vis-
ual signals are activated automatically when
the engine is started if the collision warning
system is switched on.
The audible warning signal can be activated/
deactivated by selecting the alternative
Collision warning on or Collis'n warning
OFF
in Car settingsCollision warning
settings
Warning sound.
Setting a warning distanceThis setting determines the distance at which
the visual and audible warnings are triggered.
Select

Collision warning settings
Warning distance
The warning distance determines the level of
sensitivity used by the system. The warning
distance
Long provides an earlier warning.
Begin by using Long and if the system gives
too many warnings, try changing to Normal.
WARNING
•The setting Short should only be used
in situations where traffic is light and
moving at low speeds.
•Collision Warning alerts the driver to the
risk of a collision but this function can-
not reduce the driver’s reaction time.
•For Collision Warning to be as effective
as possible, it is recommended that Dis-
tance Alert be set to 4 or 5, see
page 170.

* Option/accessory, for more information, see Introduction.175
NOTE
•When Adaptive Cruise Control is used,
the warning light and signal will be used
by that function, even if the warnings
provided by Collision Warning have
been deactivated by the driver.
•In situations where traffic is moving at
considerably different speeds, or if the
vehicle ahead brakes suddenly, warn-
ings may be considered to be late, even
if the setting
Long has been selected.
Checking settingsThe current Collision Warning settings can be
checked by going into the menu system at Car
settings
Collision warning settings.
See page 122 for more information on the
menu system.
Limitations
Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the visual
warning signal in the windshield difficult to see.
For this reason, always activate the audible
warning signal.
Slippery driving conditions increase braking
distance, which can reduce the system's
capacity to avoid a collision. In these condi-tions, the ABS and DSTC systems provide the
best possible braking effect while helping to
maintain stability.
NOTE
The visual warning signal may be temporar-
ily disengaged in the event of high passen-
ger compartment temperature due to strong
sunlight, etc. If this occurs, the audible
warning signal will be used, even if it has
been deactivated in the menu system.
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
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 stationary or slow-moving vehicles
and may therefore give delayed or no
warnings if your vehicle’s speed is
above approximately 45 mph
(70 km/h).
•Warnings for stationary or slow-moving
vehicles may not be provided in dark
conditions.
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 165.
If no warning is given, or if a warning is delayed,
Auto-brake will also not be provided or will be
delayed.

Collision warning with Auto-brake*
04
176* Option/accessory, for more information, see Introduction.
NOTE
If warnings are given too frequently, the
warning distance can be reduced (see
page 174). This causes the system to pro-
vide later warnings, which decreases the
total number of warnings provided.
The camera’s limitationsThe camera is used by Collision Warning with
Auto-brake, Driver Alert Control (see
page 179), and Lane Departure Warning (see
page 182).
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.
WARNING
•The camera has the same limitations as
the human eye. In other words, its
“vision is impaired” by adverse weather
conditions such as heavy snowfall,
dense fog, etc. These conditions may
reduce the function of systems that
depend on the camera or cause these
systems to temporarily stop function-
ing.
•Never place any objects, decals, etc.,
on the windshield in front of the camera.
This could reduce or block the camera’s
function, and could cause one or more
of the systems that utilize the camera to
stop functioning.
•Strong sunlight, reflections from the
road surface, ice or snow covering the
road, a dirty road surface, or unclear
lane marker lines may drastically reduce
the camera’s capacity to detect the side
of a lane or another vehicle.
Fault tracing and actions
If the message Windscreen Sensors
blocked is displayed, this means that the cam-
era is obscured and cannot detect vehicles or
road marker lines in front of the vehicle.
This, in turn, means that Collision Warning with
Auto-brake, Lane Departure Warning, and
Driver Alert Control will not have full function-
ality.
The table lists possible causes for this mes-
sage being displayed, and suitable actions.

Lane Departure Warning (LDW)–
introduction
This function is designed to help reduce the
risk of accidents in situations where the vehicle
leaves its lane and there is a risk of driving off
the road or into the opposite lane. LDW con-
sists of a camera that monitors the lane’s side
marker lines. The driver is alerted by an audible
signal if the vehicle crosses a side marker line
or the road’s center dividing line.
Operation and function
LDW can be switched on or off by pressing the
button on the center console. A light in the but-
ton illuminates when the function is on.
The trip computer display shows
Lane Depart
Warn Unavailable when the function is in
standby mode.
When LDW is in standby mode, the function is
activated automatically after the camera has
monitored the road’s side marker lines and the
vehicle’s speed exceeds 40 mph (65 km/h).
Lane Depart Warn Available will be dis-
played.
If the camera can no longer monitor the road’s
side marker lines, or if the vehicle’s speed fallsbelow 37 mph (60 km/h), LDW will return to
standby mode and
Lane Depart Warn
Unavailable will be displayed.
If the vehicle unexpectedly crosses the lane’s
left or right side marker lines, the driver will be
alerted by an audible signal.
No warning signal will be given in the follow-
ing situations:
•The turn signal is being used
•The driver’s foot is on the brake pedal1
•The throttle pedal is pressed quickly
•If the steering wheel is moved quickly
•In sharp turns that cause the vehicle’s
body to sway.
See page 176 for information on the camera’s
limitations.
WARNING
The driver will only be warned once for each
time the wheels cross a marker line. No
alarm will be given if a marker line is
between the wheels.
1A warning will be given even when Increased sensitivity has been selected.

Park assist*
04
184* Option/accessory, for more information, see Introduction.
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
•Front park assist is disengaged auto-
matically when the parking brake is
applied.
•If the vehicle is equipped with front and
rear park assist, both systems will be
deactivated by pressing the button.

Front park assist
G021424
The distance monitored in front of the vehicle
is approximately 2.5 ft (0.8 m). The audible sig-
nal comes from the audio system's front
speakers.
It may not be possible to combine auxiliary
headlights and front park assist since these
lights could trigger the system's sensors.
NOTE
Front park assist is deactivated when the
parking brake is applied and or when the
gear selector is in the P position.
Faults in the system
If the information symbol illuminates and Park
assist syst Service required is shown on the
information display, this indicates that the sys-
tem is not functioning properly and has been
disengaged. Consult a trained and qualified
Volvo service technician.
CAUTION
In certain circumstances, the park assist
system may give unexpected warning sig-
nals that can be caused by external sound
sources that use the same ultrasound fre-
quencies as the system. This may include
such things as the horns of other vehicles,
wet tires on asphalt, pneumatic brakes,
motorcycle exhaust pipes, etc. This does
not indicate a fault in the system.

Rear Park Assist Camera (PAC)*
04
188* Option/accessory, for more information, see Introduction.
Introduction
The Park Assist Camera uses the display on the
dashboard to show the area behind the car
while you are backing up.
PAC also shows guiding lines in the on-screen
image to indicate the direction that the vehicle
will take as it moves rearward, which helps
simplify parallel parking, backing into a tight
space or when attaching a trailer to the vehicle.
NOTE
PAC can only be installed on vehicles equip-
ped with the Volvo’s own navigation system
VNS.
WARNING
•PAC is designed to be a supplementary
aid when parking the vehicle. It is not,
however, intended to replace the
driver’s attention and judgment.
•The camera has blind spots where it
cannot detect objects or people behind
the vehicle.
•Pay particular attention to people or ani-
mals that are close to the vehicle.
Function
The driver sees what is behind the vehicle and
if a person or animal should suddenly appear
from the side.
PAC is mounted on the rear of the trunk lid,
near the opening handle.
The camera has built-in electronics that help
reduce the “fish-eye” effect so that the image
shown on the screen is as natural as possible.
This may cause some objects on the screen to
“lean,” which is normal.
WARNING
Objects seen on the screen may be closer
than they appear to be.
Ambient lighting conditionsThe camera automatically monitors the ambi-
ent lighting conditions behind the vehicle and
constantly adjusts sensitivity to light. This may
cause the brightness and quality of the image
on the screen to vary slightly. Sensitivity to light
is increased in dark conditions or in bad
weather, which may affect image quality.
If the image on the screen seems too dark,
brightness can be increased with the thumb
wheel on the lighting panel.
NOTE
In order to function properly, the camera
lens should always be kept clean. This is
particularly important in bad weather. Keep
the lens free of dirt, ice or snow.
Using PAC
ActivationPAC is activated when the gear selector is
moved to R if the system is set to Automaticunder Parking camera settings in the menu
system.
If the Volvo Navigation System (VNS) is in use,
PAC will automatically override the navigation
system to show the camera's image on the
screen instead of navigation information, for as
long as reverse gear is selected.

04 Comfort and driving pleasure
Rear Park Assist Camera (PAC)*
04

* Option/accessory, for more information, see Introduction.189
DeactivationMove the gear selector from R to another posi-
tion. There is a slight delay in the PAC system,
which means that the view from behind the
vehicle will remain on the screen for approxi-
mately 15 seconds after the gear selector has
been moved from the R position or until the
vehicle reaches a forward speed of 6 mph
(10 km/h). The screen will then revert to the
mode that it was in before R was selected and
will, for example, display navigation system
information.
Guiding lines
G000000
The lines on the screen are projected as if they
were a path on the ground behind the vehicle
and are affected by the way in which the steer-
ing wheel is turned. This enables the driver tosee path the vehicle will take, even if he/she
turns the steering wheel while backing up.
NOTE
When backing up with a trailer, the guiding
lines show the path that the vehicle will
take, not the trailer.
WARNING
Keep in mind that the image on the screen
only shows the area behind the vehicle. The
driver must always watch for people, ani-
mals, other vehicles, etc., near the sides of
the vehicle when turning while backing up.
Marker lines
The PAC system's lines
Marker line for a 1-foot (30-centimeter)
zone behind the vehicle
Marker line for the clear back-up zone
"Wheel tracks"
The solid line (1) indicates a zone within 1 ft
(30 centimeters) of the rear bumper.
The dashed line (2) indicates the clear zone of
approximately 5 feet (1.5 m) behind the
bumper. These lines also indicate the outmost
limits that any object (door mirrors, corners of
the body, etc.) extends out from the vehicle ,
even when the it turns.
The "wheel tracks" (3) between the side marker
lines show where the wheels will roll and can
extend up to approximately 10.5 ft (3.2 m)
behind the bumper if there are no objects in the
way.
