Condensation on the inside of the windows
Keeping the insides of the windows clean will help reduce the amount of condensation thatforms on the windows. Use a commercialwindow cleaning agent to clean the windows.
Ice and snow
Always keep the air intake grille at the base of the windshield free of snow.
Cabin air filter
Replace the cabin air filter with a new one at the recommended intervals. Please refer toyour 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.
Sensors
The sunlight sensor on the dashboard and passenger compartment temperature sensorin the ECC control panel should not be cov-ered in any way as this could cause incorrectinformation to be sent to the ECC system.
Parking the vehicle in warm weather
If your vehicle has been parked in the sun in warm weather, opening the windows andmoonroof* for several minutes before drivingwill help release the warm air from the pas-senger compartment. When the engine is run-ning, close the windows and moonroof anduse the recirculation function for severalminutes to enable the air conditioning to coolthe compartment as quickly as possible.
Windows and optional moonroof
The ECC system will function best if the win- dows and optional moonroof are closed. Ifyou drive with the moonroof open, we recom-mend that you manually adjust the tempera-ture and blower control (the LED in the AUTO
switch should be off).
Acceleration
The air conditioning is momentarily disen- gaged during full-throttle acceleration.
Climate control maintenance
Special tools and equipment are required to maintain and carry out repairs on the climatesystem. Work of this type should only bedone by a trained and qualified Volvo servicetechnician.
Refrigerant
Volvo cares about the environment. The air conditioning system in your vehicle containsa CFC-free refrigerant – R134a (HFC134a).This substance will not deplete the ozonelayer. The approximate amount of R134acontained in the system is a follows: 6-cylinder engine Single A/C system: 1.5 lbs (700 g) Dual 1
A/C system: 2.2 lbs (1000 g)
The system also uses PAG oil.

Functions
A/C – ON/OFF
•The air conditioning functions only at temperatures above 32°F (0°C).
• While the Defroster function is selected,the air conditioning is temporarily acti-vated to dehumidify the air, even if youhave manually switched the air condition- ing off. This will only function if the bloweris not switched off.
Press the switch to turn the air conditioning on or off. The " ON" or " OFF" LED will light up
to indicate if the system is switched on or off.Other functions will still be regulated auto-matically (if the AUTO switch is on).
Interior air quality sensor*
Some vehicles are equipped with a multifilter and air quality sensor. The filter separatesgases and particles, thereby reducing theamounts of odors and contaminants enteringthe vehicle. The air quality sensor detectsincreased levels of contaminants in the out-side air. When the air quality sensor detects

contaminated outside air, the air intake closes and the air inside the passenger compart-ment is recirculated, i.e. no outside air entersthe vehicle. The filter also cleans recirculatedpassenger compartment air. When the ECC system is in the
AUTO mode,
the green LED will be on.
Recirculation
Press this switch to engage the recirculation function (air in the passenger compartmentrecirculates – no fresh air enters the compart-ment). The LED in the switch will light up toindicate that the function is engaged. • Use this function if the outside air is con- taminated with exhaust gases, smoke,etc or to heat/cool the vehicle quickly.
• Recirculation should not be used for morethan 15 minutes. If your windows begin tofog or mist, make sure that the recircula-tion function is switched off.
• Selecting
Defroster automatically
switches recirculation off.
• Timer mode activation: (Vehicles equip-ped with the Interior Air Quality systemhave no timer mode) Press and hold therecirculation button for at least 3 secondsto activate a recirculation timer mode.The amber LED in the recirculation buttonwill flash 5 times to show that the timermode is being activated. In timer mode, each time the recirculation button ispressed, the climate control system willrecirculate the air in the passenger com-partment for 5 – 12 minutes, dependingon the outside air temperature, and thenrevert back to fresh air.
• Timer mode deactivation: Press and holdthe recirculation button for 3 seconds.The amber LED in the recirculation buttonwill illuminate steadily for 5 seconds toshow a return to "normal" mode.
• In normal mode, when the recirculationbutton is pressed, the climate controlsystem will recirculate the air in the pas-senger compartment until the recircula-tion button is pressed again.
• Timer mode memory: If the vehicle isturned off while timer mode is active,timer mode will still be active when thevehicle is restarted.
AUTO
This function automatically regulates the Electronic Climate Control system so that theselected temperatures are maintained. Theblower, heating, air distribution (air flow), airconditioning, and optional air quality sensorare controlled. If you prefer to manually setany of these functions, the remaining func-tions will still be controlled automatically.Pressing the
AUTO button overrides any set-
tings that were previously made manually.
Air distribution
G027267
• Air flow to windows
• Air through panel vents
• Air through floor vents
Press AUTO to automatically regulate air flow
or press any combination of the controls shown in the illustration to manually adjust airflow. An LED in the switch will light up if an airflow control has been pressed.

OperationPress to operate the air quality sensor (nor-mal setting). or: Select one of the following three functions by pressing 1, 2 or 3 times.
1. The AUT LED lights. The air quality sen-
sor is now activated.
2. No LED lights. Recirculation is not acti- vated unless needed to cool the passen- ger compartment in a warm climate.
3. The MAN LED lights. Recirculation is now
activated.
Keep in mind the following:
• Make it a rule to have the air quality sen- sor activated at all times.
• Recirculation is limited in cold climates toavoid fogging.
• If window fogging occurs, you shoulddeactivate the air quality sensor. Also usethe defroster functions for the windshield,side windows and rear window, seepage 98. •
The filter should be changed at the inter-vals recommended in the service sched-ule. However, if the vehicle is used in aseverely contaminated environment, itmay be necessary to change the filtermore frequently.

Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts andstops and adjusting the speed of your vehicleto immediate traffic conditions. Observe thefollowing rules:
• Bring the engine to normal operating tem- perature as soon as possible by drivingwith a light foot on the accelerator pedalfor the first few minutes of operation. Acold engine uses more fuel and is subjectto increased wear.
• Whenever possible, avoid using the vehi-cle for driving short distances. This doesnot allow the engine to reach normaloperating temperature.
• Drive carefully and avoid rapid accelera-tion and hard braking.
• Use the transmission's
D (Drive) position
as often as possible and avoid using"kickdown" to help improve fuel econ-omy.
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extraload) in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when tires are cold).
• Remove snow tires when threat of snowor ice has ended. •
Note that roof racks, ski racks, etc,increase air resistance and also fuel con-sumption.
• At highway driving speeds, fuel consump-tion will be lower with the air conditioningon and the windows closed than with theair conditioning off and the windowsopen.
• Using the onboard trip computer's fuelconsumption modes can help you learnhow to drive 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 oth- ers are checked at the standard MaintenanceService intervals.
CAUTION
Drive slowly and carefully if going through standing water (i.e. flooded roadways,etc.). Damage to the engine could result ifexcess water is drawn in through the airintake system. Never drive the vehicle inwater deeper than 18 inches (48 cm).
