Climate – general information
The vehicle is equipped with Electronic Cli- mate Control (ECC) (p. 128) that cools, heatsor dehumidifies the air in the passenger com-partment.
Air conditioning
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.
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 (p. 132) should beused to remove fog or mist from the inside ofthe windows. Keeping the windows cleanwith a commercially available window wash-ing spray will also help prevent fogging ormisting.
Temporary shut-off of the air conditioning
The air conditioning (p. 131) is momentarily disengaged during full acceleration or whendriving uphill with a trailer. This may result ina temporary 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.

Climate – sensors
The climate system utilizes a number of sen- sors to help regulate the temperature andhumidity level in the passenger compartment.
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.

Active chassis* (Four C)
Active chassis, Four-C (Continuously Controlled Chassis Concept), regulates thecharacteristics of the shock absorbers so thatthe vehicle's driving characteristics can beadjusted. There are three settings: Comfort,Sport and Advanced.
Operation
Chassis settings
Use the buttons in the center console to change setting. The setting in use when theengine is switched off is activated the nexttime the engine is started.
NOTE
This system is available on Canadian mod- els only.
ComfortComfort mode offers a somewhat softer ride and the transmission shifts gears at lowerrpm. This mode is particularly suitable forlong-distance highway driving. The indicatorlight in the button will be on when this modeis selected.
SportIn this mode, the vehicle's body sway is reduced during cornering and steeringresponse is more immediate. The transmis-sion shifts up at higher rpm for sportier driv-ing. The indicator light in the button will be onto indicate that Sport mode has beenselected.
AdvancedIn this mode, body sway in curves is minimal and steering response is very direct. Gearshifting is done at high rpm in each gear fordynamic and active driving.

Stability system – introduction
The Electronic Stability Control (ESC) system consists of a number of functions designed tohelp reduce wheel spin, counteract skiddingand to generally help improve directional sta-bility.
A pulsating sound will be audiblewhen the system is actively operat-ing and is normal. Acceleration willalso be slightly slower than normal.
WARNING
ESC is a supplementary aid and cannot deal with all situations or road conditions. The driver is always responsible for oper- ating the vehicle in a safe manner inaccordance with current traffic regulations.
ESC consists of the following functions:
• Traction control
• Spin control
• Active Yaw Control
• Trailer Stability Assist
Traction Control (TC)This function is designed to help reduce wheel spin at low speeds by transferringpower from a drive wheel that begins to losetraction to the wheel on the opposite side ofthe vehicle (on the same axle).

Spin Control (SC)The SC function is designed to help prevent the drive wheels from spinning while the vehi-cle is accelerating.
Active Yaw Control (AYC)This function helps maintain directional stabil- ity, for example when cornering, by brakingone or more of the wheels if the vehicleshows a tendency to skid or slide laterally.
Trailer Stability Assist (TSA)1The TSA helps stabilize a vehicle that is tow- ing a trailer when the vehicle and trailer havebegun to sway. See Trailer Stability Assist(TSA) (p. 283) for more information. This system is automatically deactivated if the driver selects
Sport mode.

Stability system – operation
Operation
Sport modeThe stability system is always activated and cannot be switched off.
However, the driver canselect Sport mode, which
offers more active drivingcharacteristics. Sport mode can be selected
in the MY CAR menus, see
My Car – introduction (p. 76).
In Sport mode, the engine management sys-
tem monitors movement of the accelerator pedal and steering wheel for sportier drivingby allowing more lateral movement of the rearwheels before ESC is activated. Under certain circumstances, such as when driving with snow chains, or driving in deepsnow or loose sand, it may be advisable totemporarily use Sport mode for maximum
tractive force. If the driver releases pressure on the acceler- ator pedal, ETC will also activate to help sta-bilize the vehicle. To switch to Sport mode:
Sport mode remains active until the driver
switches it off in the menu or until the engine is switched off. ETC will return to normal mode when the engine is restarted.

Park assist – introduction
The park assist system is designed to assist you when driving into parking spaces,garages, etc. An audible signal and symbolsin the audio system’s display indicate the dis-tance to the object. The park assist system utilizes ultrasound sensors in the front bumper and rearbumper(s) to measure the distance to a vehi-cle or an object that may be close to the frontor rear of your vehicle.
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.

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 intermittent tone 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 My Car – introduc-tion (p. 76) for a description of the menusystem.
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 Park assist – operation(p. 234).
• 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.

Park assist – troubleshooting
Faults in the systemIf 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.
