Activating DACIn the center instrument panel, go to Car
settings and select Driver Alert on.
The function is activated when the
vehicle exceeds a speed of 40 mph
(65 km/h). The display will show level
markings of 1–5 bars, where a low

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.

Park assist*
04

* Option/accessory, for more information, see Introduction.185 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.

Views in the display
Visual indicatorThe audio system’s display gives an overview
of the vehicle’s position in relation to a
detected object.
The markers in the display indicate that one or
more of the four sensors has detected an
object. The greater the number of markers, the
closer the vehicle is to the object.
Display in a vehicle with rear park assist
only: An object has been detected by both of
the right rear sensors.
Display in a vehicle with both front and rear
park assist. The solid marker in this example
indicates that an object is closer than approx-
imately 1 foot (30 cm) to the right front sensor.
Display in a vehicle with both front and rear
park assist: Reverse gear is selected and no
objects have been detected in front of or
behind the vehicle.
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 (example 2 in
the illustration). If there are objects within this
distance both behind and in front of the vehicle,
the tone alternates between front and rear
speakers.
If the volume of another source from the audio
system is high, this will be automatically low-
ered.
Rear park assist
G017833
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.

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.
Cleaning the sensors
Location of the front sensors
Location of the rear sensors
The sensors must be cleaned regularly to
ensure that they work properly. Clean them

with water and a suitable car washing deter-
gent.
Ice and snow covering the sensors may cause
incorrect warning signals.
NOTE
If the sensors are obstructed by e.g., dirt,
snow, or ice, this could result in false warn-
ing signals from the park assist system.

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

* Option/accessory, for more information, see Introduction.189 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 tailgate, near the open-
ing 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.
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 to
see 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.
Vehicles equipped with Park Assist
G031931
If the vehicle is equipped with the optional Park
Assist system, the distance to an object will be
indicated more exactly and colored markers in
the display indicate which of the sensor(s) has
detected the object.
