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.

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.

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 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.
Marker (color)Distance to object
Yellowmore than 5 ft (1.5 m)
Orange5–1 ft (0.3–1.5 m)

* Option/accessory, for more information, see Introduction.189
These lines are affected by movements of the steering wheel. The vehicle's approxi-mate outer dimension are shown by twodashed lines.
• The graphic lines will not be displayedwhen backing up with a trailer that is con-nected to the vehicle's electrical system.
• Objects on the ground that are closerthan 1 ft (30 centimeters) cannot bedetected by the camera.
• The camera is active for approx.5 seconds after the gear selector ismoved to
R or until the vehicle's speed
exceeds 6 mph (10 km/h).
• The optional Park Assist sensors and theparking camera work together and infor-mation from the sensors is shown graphi-cally on the display.
• The graphic lines shown on the screenwhen the vehicle backs up can be disa-bled in the settings menu.
• The system can be switched off by press-ing
CAM . By default, the system is acti-
vated when the gear selector is moved toR . This setting can be changed in the MY
CAR menu.
• If there are two cameras installed on thevehicle*, to switch between cameras, turnTUNE
(at least one of the cameras has to
be active), press CAM repeatedly or use
the center console controls. If the front camera is on, it overrides the optionalpark assist system's visual indicator butthere will still be an audible signal.
Limitations
Even if a fairly small section of the screen image appears to be obstructed, this maymean that a relatively large area behind thevehicle is hidden and objects there may notbe detected until they are very near the vehi-cle.
NOTE
Bicycle carriers or other accessories mounted on the tailgate may obstruct thecamera's field of view.
Keep in mind
•
Keep the camera's lens free of dirt, ice and snow. Remove ice and snow care-fully to avoid scratching the lens.
• Clean the lens regularly with warm waterand a suitable car washing detergent.

Introduction
Air conditioningThe vehicle is equipped with Electronic Cli- mate Control (ECC). The climate control sys-tem cools, heats or dehumidifies the air in thepassenger compartment.
NOTE
• The air conditioning can be switched off, but to ensure the best possible cli-mate comfort in the passenger com-partment and to prevent the windowsfrom misting, it should always be on.
• In warm weather, a small amount ofwater may accumulate under the carwhen it has been parked. This water iscondensation from the A/C systemand is normal.
Sensor location
•
The sunlight sensor is located on the top side of the dashboard.
NOTE
The sunlight sensor monitors which side of the car that is most exposed to sunlight.This can mean that the temperature maydiffer between the right and left-side airvents, even if the temperatures set for bothsides of the passenger compartment arethe same.
•The temperature sensor for the passen- ger compartment is located below the cli-mate control panel.
• The outside (ambient) temperature sensoris located on the door mirror.
• The humidity sensor* is located in theinterior rearview mirror.
NOTE
Do not cover or block the sensors with clothing or other objects.
Side windows and moonroofTo ensure that the air conditioning works optimally, the side windows, and the optionalmoonroof should be closed.
Fog on the inside of the windowsThe defroster function should be used toremove fog or mist from the inside of the win-dows. Keeping the windows clean with acommercially available window washing spray will also help prevent fogging or mist-ing.
Temporary shut-off of the air
conditioning
The air conditioning is momentarily disen-gaged during full acceleration or when drivinguphill with a trailer. This may result in a tem-porary increase in cabin temperature.
Ice and snowAlways keep the air intake grille at the base ofthe windshield free of snow.
Climate system maintenanceSpecial tools and equipment are required tomaintain and carry out repairs on the climatesystem. Work of this type should only bedone by a trained and qualified Volvo servicetechnician.
RefrigerantVolvo cares about the environment. The airconditioning system in your car contains aCFC-free refrigerant – R134a. This substancewill not deplete the ozone layer. The air con-ditioning system contains 1.76 lbs (800 g) ofR134a. The systems uses PAG oil.

your Warranty and Service Records Informa- tion booklet, or consult a trained and qualifiedVolvo service technician for these intervals.The filter should be replaced more often whendriving under dirty and dusty conditions. Thefilter cannot be cleaned and therefore shouldalways be replaced with a new one.
NOTE
There are different types of cabin air filters. Ensure that the correct type is installed.
Interior Air Quality System (IAQS)A multifilter helps reduce gases and particles in the incoming air, thereby reducing the lev-els of odors and contaminants entering thevehicle. The air quality sensor detectsincreased levels of contaminants in the out-side air. When the air quality sensor detectscontaminated outside air, the air intake closesand the air inside the passenger compart-ment is recirculated, i.e., no outside air entersthe vehicle. The filter also cleans recirculatedpassenger compartment air.
NOTE
Contact your Volvo retailer for IAQS air fil- ter replacement intervals.
Materials used in the cabinThe materials used in the cabin have been developed to help minimize the amount ofdust and make the cabin easier to keepclean. All floor mats can be easily removedfor cleaning. Use car cleaning products rec-ommended by Volvo. See also the informa-tion beginning on page 364.
Menu settingsThe default settings for four of the climatesystem's functions can be changed in themenu system.• Blower speed in automatic mode.
• Recirculation timer for passenger com- partment air.
• Automatic rear window defrosting.
• The optional Interior Air Quality System(IAQS).
The functions can also be returned to factory settings in the menu system. See page 199 for a description of the menu system.
Air distribution
G017699
The incoming air is distributed from a number of different vents in the passenger compart-ment. Air distribution is fully automatic in AUTO
mode.If desired, air distribution can be controlled manually, see page 213.

Interior Air Quality System–IAQS*This system consists of a multifilter and an air quality sensor. The filter helps remove gasesand particles from the incoming air, therebyreducing the amounts of odors and contami-nants entering the vehicle. The air quality sen-sor detects increased levels of contaminantsin the outside air. When the air quality sensordetects contaminated outside air, the airintake closes and the air inside the passenger compartment is recirculated, i.e., no outsideair enters the vehicle. The filter also cleansrecirculated passenger compartment air.When the
AUTO button is depressed the air
quality sensor is always engaged. Activate or deactivate this function in
