Driver Alert System*
04

* Option/accessory, for more information, see Introduction.175 Introduction
The Driver Alert System is designed to help a
driver who may be becoming fatigued or who
is inadvertently leaving the lane.
The Driver Alert System consists of two differ-
ent functions that can be switched on together
or separately.
•Driver Alert Control (DAC)
•Lane Departure Warning (LDW)
When one or both of the functions has been
switched on, it is in standby mode and is acti-
vated when the vehicle exceeds a speed of
40 mph (65 km/h).
The function deactivates if speed goes under
37 mph (60 km/h).
Both functions use a camera that is dependent
on the road/lane being clearly marked by pain-
ted lines on each side.
WARNING
The Driver Alert system does not function in
all situations and is designed to be a sup-
plementary aid. It is not, however, intended
to replace the driver’s attention and judge-
ment.
Driver Alert Control (DAC)–general
information
G017332
This function is intended to alert the driver if
his/her driving becomes erratic, such as if the
driver is distracted or fatigued.
NOTE
The camera has certain limitations, see
page 161.
A camera monitors the painted lines marking
the lane in which the vehicle is traveling and
compares the direction of the road with the
driver’s movements of the steering wheel. The
driver is alerted if the vehicle does not follow
the lane smoothly.DAC is designed to help detect a slowly chang-
ing driving pattern. It is primarily intended to be
used on main roads and is not meant for use in
city traffic.
WARNING
•DAC is not intended to extend the dura-
tion of driving. Always plan breaks at
regular intervals to help remain alert.
•In certain cases, fatigue may not affect
the driver’s behavior. In situations of
this type, no warning will be provided.
Therefore, it is important to take breaks
at regular intervals, regardless of
whether or not DAC has given a warn-
ing.
LimitationsIn certain situations, DAC may provide warn-
ings even if the driver’s driving pattern has not
become erratic.
•if the driver is testing the LDW function
•in strong crosswinds
•on grooved road surfaces.

Operating DAC
Certain settings can be made from the menu
system controlled from the center instrument
panel, see page 120 for more information on
the menu system.
The current system status can be checked on
the trip computer’s display by using the but-
tons on the left steering wheel lever.
Thumb wheel. Turn this wheel until Driver
Alert is displayed. The second line shows
the alternative Off, Unavailable, or[-----], i.e., the number of bars.
READbutton. Confirms and erases a mes-
sage in the display.
Activating DACIn the center instrument panel, go to Car
settings Driver Alertand select 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
number of bars indicates erratic driving. A high
number of bars indicates stable driving.
If the vehicle is being driven erratically, the
driver will be alerted by an audible signal and
the message Driver Alert, Time for a break is
displayed. The warning will be repeated after a
short time if the driving pattern remains the
same.
WARNING
•An alert should be taken seriously since
it is sometimes difficult for a driver to
realize that he/she is fatigued.
•In the event of a warning or if the driver
feels fatigued, stop as soon as possible
in a safe place and rest.

Lane Departure Warning (LDW)–
general information
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 falls
below 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 161 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
180* 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.
This system is available in the rear bumper
only, or in both the front and rear bumpers.
Park assist utilizes four ultrasound sensors in
the bumper(s) to measure the distance 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 system’s dis-
play indicate the distance to the object
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

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

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.
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.

* Option/accessory, for more information, see Introduction.183 Introduction
G021426
BLIS camera
Indicator light
BLIS symbol
The Blind Spot Information System (BLIS) is an
information system that indicates the presence
of another vehicle moving in the same direction
as your vehicle in the side-view mirror's "blind
area."
CAUTION
The BLIS system should only be repaired by
a trained and qualified Volvo service tech-
nician.
WARNING
•BLIS is an information system, NOT a
warning or safety system.
•BLIS does not eliminate the need for
you to visually confirm the conditions
around you, and the need for you to turn
your head and shoulders to make sure
that you can safely change lanes.
•As the driver, you have full responsibility
for changing lanes in a safe manner.
The system is based on digital camera tech-
nology. The cameras are located beneath the
side-view mirrors.
When one (or both) of the cameras have
detected a vehicle in the blind area (up to
approximately 10 ft. (3 meters) from the side of
your vehicle, and up to approximately 31 ft.
(9.5 meters) behind the side-view mirror), see
the illustration, the indicator light in the door
panel illuminates. The light will glow continu-
ously to alert the driver of the vehicle in the
blind area.
NOTE
The door panel indicator light illuminates on
the side of the vehicle where the system has
detected another vehicle. If your vehicle is
passed on both sides at the same time, both
lights will illuminate.
BLIS has an integrated function that alerts the
driver if a fault should occur with the system.
For example, if one or both of the system's
cameras are obscured, a message (see the
table on page 186) will appear in the informa-
tion display in the instrument panel. If this
occurs, clean the camera lenses. If necessary,
the system can be temporarily switched off (for
instructions, see page 185).

Areas monitored by BLIS Distance A = approx.
31 ft. (9.5 meters), Distance B = approx. 10 ft.

184* Option/accessory, for more information, see Introduction.
When does BLIS function
The system functions when your vehicle is
moving at speeds above 6 mph (10 km/h).
When you pass another vehicle:The system reacts when you pass another
vehicle at a speed of up to 6 mph (10 km/h)
faster than that vehicle.
When you are passed by another vehicle:The system reacts if your vehicle is passed by
another vehicle at a speed of up to 43 mph
(70 km/h) faster than your vehicle.
WARNING
•BLIS does not function in sharp curves.
•BLIS does not function when your vehi-
cle is backing up.
•If you are towing a wide trailer, this may
prevent the BLIS cameras from detect-
ing other vehicles in adjacent lanes.
How BLIS functions in daylight and
darkness
Daylight
BLIS reacts to the shape of surrounding vehi-
cles. The system is designed to help detect
motor vehicles such as cars, trucks, buses,
motorcycles, etc.
DarknessBLIS reacts to the headlights of surrounding
vehicles. In order to be detected by BLIS, a
vehicle in the blind area must have its head-
lights on. This means, for example, that the
system will not detect a trailer without head-
lights that is being towed behind a car or truck.WARNING
•BLIS does not react to cyclists or
mopeds.
•BLIS does not react to vehicles that are
standing still.
•The function of the BLIS cameras may
be affected by intense light, or when
driving at night in areas where there are
no external sources of light (e.g., street
lights, other vehicles, etc.). In such
cases, the system may react as if the
cameras were obscured.
•In both of the above mentioned condi-
tions, a message will appear in the infor-
mation display.
•When driving in such conditions, the
system's function will be limited or it
may be temporarily switched off, see
page 185 for instructions.
•When the message is no longer dis-
played, BLIS will return to normal func-
tion.
•The BLIS cameras have the same limi-
tation as the human eye. In other words,
their "vision is impaired" by adverse
weather conditions such as heavy
snowfall, dense fog, etc.
