182* 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 ultrasound sensors inthe front bumper and rear bumper(s) to meas-ure the distance to a vehicle or an object thatmay be close to the front or rear of your vehi-cle. An audible signal and symbols in theaudio system’s display indicate the distanceto the object.
NOTE
A trailer hitch whose wiring is integrated with the vehicle's electrical system will beincluded in the measurement of the availa-ble space behind the vehicle.
WARNING
Park Assist is an information system, NOT a safety system. This system is designedto be a supplementary aid when parkingthe vehicle. It is not, however, intended toreplace 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 thebutton in the center console illuminates whenthe system is on.
• The front park assist system is active from the time the engine is started untilthe vehicle exceeds a speed of approxi-mately 6 mph (10 km/h). It is also activewhen the vehicle is backing up.
• Rear park assist is active when the engineis running and reverse gear has beenselected.
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.

NOTE
• Rear park assist is deactivated auto- matically when towing a trailer if Volvogenuine trailer wiring is used. If a non-Volvo trailer hitch is being used, it maybe necessary to switch off the systemmanually, see page 182.
• The system will not detect highobjects, such as a loading dock, etc.
• Objects such as chains, thin shinypoles or low objects may temporarilynot be detected by the system. Thismay result in the pulsing tone unex-pectedly stopping instead of changingto a constant tone as the vehicleapproaches the object. In such cases,use caution when backing up or stopthe vehicle to help avoid damage.
Front park assist
G021424
The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audiblesignal comes from the audio system's frontspeakers. It may not be possible to combine auxiliary headlights and front park assist since theselights could trigger the system's sensors.
NOTE
Front park assist is deactivated when the parking brake is applied and or when thegear selector is in the
P position.
Faults in the system
If the information symbol illuminates andPark assist syst Service required is shown
on the information display, this indicates that the system is not functioning properly andhas been disengaged. Consult a trained andqualified Volvo service technician.
CAUTION
In certain circumstances, the park assist system may give unexpected warning sig-nals that can be caused by external soundsources that use the same ultrasound fre-quencies as the system. This may includesuch things as the horns of other vehicles,wet tires on asphalt, pneumatic brakes,motorcycle exhaust pipes, etc. This doesnot indicate a fault in the system.

Rear Park Assist Camera (PAC)*
04
186* Option/accessory, for more information, see Introduction.
Introduction
The Park Assist Camera uses the display in the center console to show the area behindthe car while you are backing up. PAC also shows guiding lines in the on- screen image to indicate the direction that thevehicle will take as it moves rearward, whichhelps simplify parallel parking, backing into atight space or when attaching a trailer to thevehicle.
NOTE
A trailer hitch whose wiring is integrated with the vehicle's electrical system will beincluded in the measurement of the availa-ble space behind the vehicle.
WARNING
• PAC is designed to be a supplemen- tary aid when parking the vehicle. It isnot, however, intended to replace thedriver’s attention and judgment.
• The camera has blind spots where itcannot detect objects or peoplebehind the vehicle.
• Pay particular attention to people oranimals that are close to the vehicle.
Function
The driver sees what is behind the vehicle and if a person or animal should suddenlyappear from the side. PAC is mounted on the tailgate, near the opening handle. The camera has built-in electronics that help reduce the “fish-eye” effect so that the imageshown on the screen is as natural as possi-ble. This may cause some objects on thescreen 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 andconstantly adjusts sensitivity to light. Thismay cause the brightness and quality of theimage on the screen to vary slightly. Sensitiv-ity to light is increased in dark conditions or inbad weather, which may affect image quality. If the image on the screen seems too dark, brightness can be increased with the thumbwheel on the lighting panel.
NOTE
In order to function properly, the camera lens should always be kept clean. This isparticularly important in bad weather.Keep the lens free of dirt, ice or snow.

Using PAC
Activation
PAC is activated when the gear selector is moved to R if the system is selected in the
MY CAR menu system or by pressing the
CAM button in the center console. See page
199 for a description of the menu system. If the Volvo Navigation System (VNS) is in use, PAC will automatically override the navi-gation system to show the camera's imageon the screen instead of navigation informa-tion, for as long as reverse gear is selected.
DeactivationMove the gear selector from R to another
position. There is a slight delay in the PACsystem, which means that the view from behind the vehicle will remain on the screenfor approximately 15 seconds after the gearselector has been moved from the
R position
or until the vehicle reaches a forward speedof 6 mph (10 km/h). The screen will thenrevert to the mode that it was in before R was
selected and will, for example, display navi-gation system information.
NOTE
If any button on the center console control panel is pressed, the camera image willdisappear from the display. Pressing CAM
will return the camera image to the display.
Guiding lines
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 whichthe steering wheel is turned. This enables thedriver to see path the vehicle will take, even ifhe/she turns the steering wheel while backingup.
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,animals, other vehicles, etc., near the sidesof the vehicle when turning while backingup.

BLIS camera
Indicator light
BLIS symbol
The Blind Spot Information System (BLIS) is an information system that indicates the pres-ence of another vehicle moving in the samedirection as your vehicle in the side-view mir-ror's "blind area."
CAUTION
The BLIS system should only be repaired by a trained and qualified Volvo servicetechnician.
WARNING
• BLIS is an information system, NOT a warning or safety system.
• BLIS does not eliminate the need foryou to visually confirm the conditionsaround you, and the need for you toturn your head and shoulders to makesure that you can safely change lanes.
• As the driver, you have full responsibil-ity for changing lanes in a safe man-ner.
The system is based on digital camera tech- nology. The cameras are located beneath theside-view mirrors. When one (or both) of the cameras have detected a vehicle in the blind area (up toapproximately 10 ft. (3 meters) from the sideof your vehicle, and up to approximately 31 ft.(9.5 meters) behind the side-view mirror), seethe illustration, the indicator light in the doorpanel illuminates. The light will glow continu-ously to alert the driver of the vehicle in theblind area.
NOTE
The door panel indicator light illuminates on the side of the vehicle where the sys-tem has detected another vehicle. If yourvehicle is passed on both sides at thesame 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'scameras are obscured, a message (see thetable on page 192) will appear in the informa-tion display in the instrument panel. If thisoccurs, clean the camera lenses. If neces-sary, the system can be temporarily switchedoff (for instructions, see page 192).
Areas monitored by BLIS Distance A = approx. 31 ft. (9.5 meters), Distance B = approx. 10 ft.(3 meters)

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 yourvehicle is backing up.
• If you are towing a wide trailer, thismay prevent the BLIS cameras fromdetecting other vehicles in adjacentlanes.
How BLIS functions in daylight and darkness
DaylightBLIS 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 thesystem will not detect a trailer without head-lights that is being towed behind a car ortruck.
WARNING
• BLIS does not react to cyclists or mopeds.
• BLIS does not react to vehicles thatare standing still.
• The BLIS cameras have the same limi-tation as the human eye. In otherwords, their "vision is impaired" byadverse weather conditions such asheavy snowfall, intense light directlyinto the camera, dense fog, etc.
LimitationsIn certain situations, the BLIS indicator light(s) may illuminate even when there are no othervehicles in the area monitored by the system.
NOTE
If the BLIS indicator lights illuminate occa- sionally even when there are no other vehi-cles in the blind area, this does not indi-cate a fault in the system. In the event of a fault,
Blind spot syst.
Service required will be displayed.
The following are several examples of situa- tions in which the BLIS indicator light(s) mayilluminate even when there are no other vehi-cles in the area monitored by the system.

Cleaning the BLIS camera lensesIn order to function optimally, the BLIS cam- era lenses must be kept clean. They can bewiped clean with a soft cloth or wet sponge.
CAUTION
• Clean the lenses carefully to avoid scratching.
• The lenses are electrically heated tohelp melt ice or snow. If necessary,gently brush away snow from the len-ses.
Switching BLIS on and off
BLIS is automatically activated when the igni- tion is switched on. The indicator lights willprovide confirmation by flashing 3 times.
• The system can be switched off by press- ing the
BLIS button in the center console
(see the illustration). The indicator light inthe button goes out when the system is switched off, and a text message is dis-played.
• BLIS can be switched on again by press-ing the button. The indicator light in thebutton will illuminate and a new text mes-sage will be displayed. Press the
OK but-
ton (see page 197) to erase the message.
Depending on the vehicle's optional equip- ment, there may not be space for the BLIS
button in the center console. In this case,BLIS can be switched on and off in the menusystem by pressing MY CAR and going to
SettingsCar settingsBLIS. See page
199 for a description of the menu system.
