Lane Departure Warning (LDW)– introduction
This function is designed to help reduce the risk of accidents in situations where the vehi-cle leaves its lane and there is a risk of drivingoff the road or into the opposite lane. LDWconsists of a camera that monitors the lane’sside marker lines. The driver is alerted by anaudible signal if the vehicle crosses a sidemarker 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 inthe button illuminates when the function ison. This is supplemented by graphic displaysin the instrument panel, for example:

Park assist*
04
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.
Park assist will be automatically reactivatedthe next time the engine is started, or if thebutton is pressed (the indicator light in thebutton 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 adetected object. The marked sectors in the display indicate that one or more of the sensors has detectedan object. The closer the car symbol comesto a sector, the closer the vehicle is to theobject. If the infotainment system is switched off, the park assist system will not be able to providea visual indicator. An audible signal will stillbe provided.
Audible signalThe Park Assist system uses an intermittenttone that pulses faster as you come close toan object, and becomes constant when youare within approximately 1 ft (30 cm) of anobject in front of or behind the vehicle. Ifthere are objects within this distance bothbehind and in front of the vehicle, the tonealternates between front and rear speakers.
NOTE
The level of the audible signal can be low- ered/raised with the infotainment volumecontrol. The level can also be set in the MYCAR menu system. See page 199 for adescription of the menu system.
If the volume of another source from the audio system is high, this will be automati-cally lowered.
Rear park assist
G017833
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The audible signalcomes from the rear speakers. The system must be deactivated when towing a trailer, carrying bicycles in a rear-mountedcarrier, etc, which could trigger the rear parkassist system's sensors.

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.

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 falsewarning signals from the park assist sys-tem.

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.

* Option/accessory, for more information, see Introduction.187
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.

"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 thebumper. These lines also indicate the out-most limits that any object (door mirrors, cor-ners of the body, etc.) extends out from thevehicle, even when it turns. The "wheel tracks" (3) between the side marker lines show where the wheels will rolland can extend up to approximately 10.5 ft (3.2 m) behind the bumper if there are noobjects in the way.
Vehicles equipped with Park Assist
Colored fields (4-one per sensor) indicate dis- tance If the vehicle is equipped with the optional Park Assist system, the distance to an objectwill be indicated more exactly and coloredmarkers in the display indicate which of thesensor(s) has detected the object. The markers change color (from yellow to orange to red) as the vehicle comes closer tothe object.
