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.

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

Handling, roadholdingVehicle load, tire design and inflation pres- sure all affect vehicle handling. Therefore,check that the tires are inflated to the recom-mended pressure according to the vehicleload. See the "Tire pressure" section. Loadsshould be distributed so that capacity weightor maximum permissible axle loads are notexceeded.
Driving through water
•The vehicle can be driven through water up to a depth of approximately 10 in.(25 cm), at a maximum speed of 6 mph(10 km/h).
• Take particular care when driving throughflowing water.
• Clean the electrical connections for trailerwiring after driving in mud or water.
• When driving through water, maintain lowspeed and do not stop in the water.
WARNING
•Avoid driving through standing or rushing water. Doing so can be dan-gerous and it may also be difficult todetermine the actual depth of thewater.
• If water cannot be avoided, after driv-ing through the water, press lightly onthe brake pedal to ensure that thebrakes are functioning normally. Wateror mud can make the brake liningsslippery, resulting in delayed brakingeffect.
CAUTION
• Engine damage will occur if water is drawn into the air cleaner.
• If the vehicle is driven through waterdeeper than 10 in (25 cm), water mayenter the differential and the transmis-sion. This reduces the oil's lubricatingcapacity and may shorten the servicelife of these components.
• Do not allow the vehicle to stand inwater up to the door sills longer thanabsolutely necessary. This could resultin electrical malfunctions.
• If the engine has been stopped whilethe vehicle is in water, do not attemptto restart it. Have the vehicle towedout of the water.
Engine and cooling systemUnder special conditions, for example when driving in hilly terrain, extreme heat or withheavy loads, there is a risk that the engineand cooling system will overheat. Proceed asfollows to avoid overheating the engine. •
Maintain a low speed when driving with a trailer up long, steep hills.
• Do not turn the engine off immediatelywhen stopping after a hard drive.

Tire Sealing System*
08
316* Option/accessory, for more information, see Introduction.
Location
IntroductionCertain models are equipped with a tire sealing system * that enables you to tempo-
rarily seal a hole in the tread surface and re- inflate a flat tire, or to adjust a tire’s inflationpressure. The system consists of an air compressor, a container for the sealing compound, wiring toconnect the system to the vehicle’s electricalsystem via one of the 12-volt sockets, and ahose used to connect the system to the tire’sinflation valve.
NOTE
The tire sealing system's compressor has been tested and approved by Volvo.
The 12-volt sockets are located in the front tunnel console, on the rear side of the centerconsole in the rear seat and in the cargoarea*, see page 225.
Accessing the tire sealing systemThe tire sealing system is stowed under thefloor of the cargo area. To access it:
1. Lift the floor hatch in the cargo area.
2. Lift out the tire sealing system.
NOTE
• The tire sealing system is only intended to seal holes on the tire’stread area, not the sidewall.
• Tires with large holes or tears cannotbe repaired with the tire sealing sys-tem.
• After use, stow the tire sealing systemproperly to help prevent rattling.
WARNING
• After using the tire sealing system, the vehicle should not be driven fartherthan approximately 120 miles (200km).
• Have the tire inspected by a trainedand qualified Volvo service technicianas soon as possible to determine if itcan be permanently repaired or mustbe replaced.
• The vehicle should not be driven fasterthan 50 mph (80 km/h) while using atire that has been temporarily repairedwith the tire sealing system.
• After using the tire sealing system,drive carefully and avoid abrupt steer-ing maneuvers and sudden stops.
