Air quality
The passenger compartment has been designed to be pleasant and comfortable, even for peoplewith asthma and contact allergies.
Passenger compartment filterReplace the cabin air filter with a new one at the recommended intervals. Please refer to your War-ranty and Service Records Information booklet, orconsult a trained and qualified Volvo service tech-nician for these intervals. The filter should bereplaced more often when driving under dirty anddusty conditions. The filter cannot be cleanedand therefore should always be replaced with anew 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 levels ofodors and contaminants entering the vehicle. Theair quality sensor detects increased levels of con-taminants in the outside air. When the air qualitysensor detects contaminated outside air, the airintake closes and the air inside the passengercompartment is recirculated, i.e., no outside airenters the vehicle. The filter also cleans recircula-ted passenger compartment air.
NOTE
Contact your Volvo retailer for IAQS air filter replacement intervals.
Materials used in the cabinThe materials used in the cabin have been devel- oped to help minimize the amount of dust andmake the cabin easier to keep clean. All floormats can be easily removed for cleaning. Use carcleaning products recommended by Volvo. Seealso the information in Cleaning the interior(p. 371).

Interior Air Quality System (IAQS) *
The Air Quality System (IAQS) consists of a mul- tifilter and an air quality sensor. The filter helpsremove gases and particles from the incomingair, thereby reducing the amounts of odors andcontaminants entering the vehicle.
The air quality (p. 129) sensor detects increased levels of contaminants in the outside air. Whenthe air quality sensor detects contaminated out-side air, the air intake closes and the air insidethe passenger compartment is recirculated, i.e.,no outside air enters the vehicle. The filter alsocleans recirculated passenger compartment air. When the AUTO (p. 134) button is depressed
the air quality sensor is always engaged. Activate or deactivate this function in

settings
Interior air quality system.
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.

Climate – menu settings
The default settings for four of the climate sys-
tem's (p. 128) functions can be changed in themenu system.
• Blower speed (p. 134) in automatic mode (p. 134).
• Recirculation timer (p. 137) for passengercompartment air.
• Automatic rear window defrosting (p. 108).
• The optional Interior Air Quality Sys-tem (p. 130) (IAQS).
The functions can also be returned to factory set-tings in the menu system. See My Car – introduction (p. 79) for a descrip- tion of the menu system.

nents, altering emission system components or location or removing components, and/orrepeated use of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen content of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.

Economical driving
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.
Economical driving conserves natural
resources
Observe the following rules: • Bring the engine to normal operating tem- perature as soon as possible by driving witha light foot on the accelerator pedal for thefirst few minutes of operation. A cold engineuses more fuel and is subject to increasedwear.
• Whenever possible, avoid using the vehiclefor driving short distances. This does notallow the engine to reach normal operatingtemperature.
• Drive carefully and avoid rapid accelerationand hard braking.
• Use the transmission's Drive (
D) position as
often as possible and avoid using kick-down.
• Using the engine's optional Eco function canhelp improve fuel economy. For additional information, see ECO
* (p. 273).
• Using the transmission's Sport mode may increase fuel consumption somewhat. Use the transmission's Drive (
D) position as often
as possible. For additional information about Sport mode, see Transmission – Geartronic (p. 265).
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when tires are cold).
• Remove snow tires when threat of snow orice has ended.
• Note that roof racks, ski racks, etc, increaseair resistance and also fuel consumption.
• At highway driving speeds, fuel consumptionwill be lower with the air conditioning on andthe windows closed than with the air condi-tioning off and the windows open.
• Using the onboard trip computer's fuel con-sumption modes can help you learn how todrive more economically.
Other factors that decrease gas mileage are:
• Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment
Some of the above mentioned items and othersare checked at the standard maintenance inter-vals.
