Washing function
–Move the right-side steering wheel lever toward the wheel to start the windshield andheadlight washers.
> After the lever is released the wipers make several extra sweeps.
CAUTION
• Use ample washer fluid when washing the windshield. The windshield should bethoroughly wet when the wipers are inoperation.
• Avoid using the washers if the fluid reser-voir is frozen or empty to help avoid dam-age to the pump.
When the washing system is used, the length of time that the windshield washers operatedepends on the ambient temperature. In coldweather, the amount of washer fluid used willalso be increased automatically to help improvecleaning.
Heated washer nozzles
*The washer nozzles are heated automatically incold weather to help prevent the washer fluidfrom freezing.
High-pressure headlight washing *High-pressure headlight washing consumes alarge quantity of washer fluid. To save fluid, theheadlights are washed once for every five timesthe windshield is washed.
Reduced washingWhen approx. 1 US quart (1 liter) of washer fluidremains in the reservoir, the headlights will nolonger be washed to conserve fluid.

Climate control systemThe vehicle is equipped with Electronic Climate Control (ECC) that cools, heats, dehumidifiesand filters the air in the passenger compartment.
4-zone climate system
4-zone system climate zones
The 4-zone climate system makes it possible to set the left- and right-side temperatures sepa-rately for the front and rears seats. All climate system settings are made from the center display and the buttons in the center con-sole. Settings for the rear seats can also bemade from the climate system panel on the rearside of the tunnel console.

Perceived temperature
The climate system regulates passenger com- partment temperature based on the perceivedtemperature, not on the actual one.
The selected passenger compartment tempera- ture is based on a physical perception relating tothe current ambient temperature, air flow, humid-ity, sunlight in the passenger compartment, etc. The system's sunlight sensor monitors the side of the car where sunlight is entering the passengercompartment. This means that the actual tem-perature may differ between the right and leftsides of the compartment, even if the tempera-ture setting is the same for both sides.

Climate system sensors The climate system's sensors help regulate the passenger compartment temperature, humiditylevel, etc.
Location of the sensors
Humidity sensor: in the rearview mirror con- sole.
Ambient temperature sensor: in the pas- senger's side door mirror.
Passenger compartment temperature sen- sor: near the center console buttons.
Sunlight sensor: on the upper side of the dashboard.
NOTE
Do not cover or block the sensors with cloth- ing or other objects.
On models equipped with the optional Interior Air Quality System, there is also an air quality sensorlocated at the climate system's air intake.

Parking climate (preconditioning)
The climate in the passenger compartment can be preconditioned and maintained, even whenthe vehicle is parked. For full functionality, the
vehicle's charging cable must be connected .

Air quality
The materials used in the passenger compart- ment have been selected and designed to bepleasant and comfortable, even for people withasthma or other types of allergies.
Materials in the passenger compartment
The materials used have been developed to help minimize the amount of dust and make the cabineasier to keep clean. All floor mats can be easily removed for cleaning. Use car cleaning products recommended byVolvo. Only use cleaning agents and car care products recommended by Volvo. Clean regularly and fol-low the instructions included with the car careproduct.
Air filtering systemsIn addition to the passenger compartment filter, the Clean Zone Interior Package * and the Interior
Air Quality System * contribute to a cleaner pas-
senger compartment environment.

Clean Zone Interior Package (CZIP)
*
The Clean Zone Interior Package includes a number of features that help further reduce aller-genic substances in the passenger compart-ment.
CZIP includes the following:
• An enhanced blower function that starts the blower when the vehicle is unlocked with theremote key to fill the passenger compart-ment with fresh air. This function starts auto-matically when required and shuts off auto-matically after a short period or if one thedoors is opened. The time for which theblower operates decreases gradually due toreduced need until the vehicle is four yearsold.
• The Interior Air Quality System (IAQS).
NOTE
In order to retain the CZIP standard, the IAQS filter must be replaced at the specified inter-vals. Consult your Volvo retailer.
Interior Air Quality System (IAQS)
*
The Interior Air Quality System uses a multifilter and an air quality sensor to remove gases, parti-cles and other contaminants from the air enter-ing the passenger compartment.
The IAQS air quality sensor monitors increased levels of contaminants in the outside air and ifcontaminants are detected, the air intake closesand the air inside the passenger compartment isrecirculated, i.e., no outside air enters the vehicle.The filter also cleans recirculated passengercompartment air.
NOTE
• The air quality sensor should always be engaged in order to obtain the best air inthe passenger compartment.
• Recirculation is limited in cold weather toavoid fogging.
• If the insides of the windows start fog-ging, disengage the air quality sensor.Use the defroster function to increaseairflow to the front, side, and rear win-dows.
