Air vents (dash)
A Open
B Closed
C Horizontal air flow
D Vertical air flow

Direct the outer air vents toward the side windows to demist.

In cold weather, close the air vents in the center of the dash to direct as much air as possible toward the windows.

Air flow

The air that is drawn into the passenger compartment is distributed from 14 ventilation points.


Air vents in door pillars
A Closed
B Open
C Horizontal air flow
D Vertical air flow

Direct the air vents toward the rear side windows to demist.

Direct the air vents toward the rear seat for the best heating/cooling effect.

AUTO

This function automatically regulates the Electronic Climate Control system so that the selected temperatures are maintained. The blower, heating, air distribution (air flow) and air conditioning are controlled. If you prefer to manually set any of these functions, the remaining functions will still be controlled automatically. Pressing the AUTO button overrides any settings that were previously made manually.



Temperature

These controls are used to individually set the temperature for both sides of the passenger compartment. Please note that the compartment will not be heated or cooled faster by setting the temperature higher or lower than necessary.
Set the control to the temperature you prefer.


Defroster

This function demists/de-ices the windshield and front side windows. The LED in the switch will light up to indicate that the defrost function is engaged. Blower speed increases automatically and the air in the passenger compartment is dehumidified. Recirculation will not function while defrost is engaged.


Heated rear window/sideview mirrors

This function demists/de-ices the rear window and sideview mirrors. The LED in the switch will light up to indicate that the heating function is engaged. See page 33 for additional information on this function.


CAUTION:

Never use ice scrapers made of metal as they can easily scratch the mirror surface.

pg. 43 Electronic Climate Control (ECC) - manual settings




Recirculation

Press this switch to engage the recirculation function (air in the passenger compartment recirculates - no fresh air enters the compartment). The LED in the switch will light up to indicate that the function is engaged.

· Use this function if the outside air is contaminated with exhaust gases, smoke, etc or to heat/cool the car quickly.

· Recirculation should not be used for more than 15 minutes. If your windows begin to fog or mist, make sure that the recirculation function is switched off.
· Selecting Defroster automatically switches recirculation off.
· Timer function: (cars equipped with the optional Interior Quality system do not have the timer function) Pressing and holding the switch for at least 3 seconds activates a timer function. The LED in the switch will flash for approximately 5 seconds. Recirculation will then always operate for periods of 5 to 12 minutes, depending on the ambient temperature, after which it will switch off automatically. Pressing the switch at any time during the recirculation period will disengage the function and allow fresh air into the passenger compartment.
Press and hold the switch again for at least 3 seconds to return the button to its original function (i.e., recirculation will remain on until you switch it off).

Blower control

Turn the control clockwise to increase or counterclockwise to decrease the blower speed. Pressing the AUTO switch will automatically regulate blower speed and override manual adjustment.

NOTE: Turning the blower control counterclockwise as far as possible (an LED next to the control will light up) will turn both the blower and the air conditioning off.


Air flow

Press AUTO to automatically regulate air flow or press any combination of the controls shown in the illustration to manually adjust air flow. An LED in the switch will light up if an air flow control has been pressed.


Air conditioning ON/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 automatically (if the AUTO switch is on).

· The air conditioning functions only at temperatures above 32° F
(0° C).

· While the Defroster function is selected, the air conditioning is temporarily activated to dehumidify the air, even if you have manually switched the air conditioning off. This will only function if the blower is not switched off.


Heated front seats (option)

Please see page 33 for more information on this function.

pg. 44 Climate control system - general information



Condensation on the inside of the windows
Keeping the insides of the windows clean will help reduce the amount of condensation that forms on the windows. Use a commercial window cleaning agent to clean the windows.

Ice and snow
Always keep the air intake grille at the base of the windshield free of snow.

Air cabin filter
Replace the air cabin filter with a new one at the recommended intervals. The filter should be replaced more often when driving under dirty and dusty conditions. The filter cannot be cleaned and therefore should always be replaced with a new one.

Sensors
The sunlight sensor on the dashboard and passenger compartment temperature sensor in the ECC control panel should not be covered in any way as this could cause incorrect information to be sent to the ECC system.

Parking the car in warm weather
If your car has been parked in the sun in warm weather, opening the windows and sun roof (option) for several minutes before driving will help release the warm air from the passenger compartment. When the engine is running, close the windows and sun roof and use the recirculation function for several minutes to enable the air conditioning to cool the compartment as quickly as possible.

Windows and optional sun roof
The ECC system will function best if the windows and optional sun roof are closed. If you drive with the sun roof open, we recommend that you manually adjust the temperature and blower control (the LED in the AUTO switch should be off).

Acceleration
The air conditioning is momentarily disengaged during full-throttle acceleration.

ECC maintenance
All maintenance on the climate control systems should be carried out by an authorized Volvo service technician only.

Refrigerant
Volvo cares about the environment. The air conditioning system in your car contains a CFC-free refrigerant - R134a. This substance will not deplete the ozone layer. The system contains 2.2 lbs (1000 g) R134a and uses PAG oil.

Passenger compartment blower
Approximately 50 minutes after the ignition is turned off, the blower may come on automatically, and run for five minutes, to remove condensation in the A/C evaporator.BR>

pg. 45 Electronic Climate Control (ECC) - with Interior Air Quality system (option)



Interior Air Quality system (option)
Some cars are equipped with a multifilter and air quality sensor. The filter separates gases and particles, thereby reducing the amounts of odors and contaminants entering the car. The air quality sensor detects increased levels of contaminants in the outside air. When the air quality sensor detects contaminated outside air, the air intake closes and the air inside the passenger compartment is recirculated, i.e. no outside air enters the car. The filter also cleans recirculated passenger compartment air. When the Air quality sensor is activated, the LED AUT comes on in the recirculation button


Operations:
Press to activate the Air quality sensor (normal setting). Or select one of three functions by pressing
1. Press the LED AUT comes on. The Air quality sensor is now activated. 2. Press no LED is lighted. Recirculation not activated. 3. Press the LED MAN comes on. Recirculation is now activated. You can switch between these three functions by repeatedly pressing

Keep the following in Mind:

· Make it a rule to have the air quality sensor activated at all times.
· Recirculation is limited in cold climates to avoid misting up.
· If misting occurs, you should deactivate the Air quality sensor.
· If the windows mist up, you can also use the windshield and side window defroster functions. See page 42.
· The filter should be changed at the intervals recommended in the service schedule. However, if the car is used in a severely contaminated environment, it may be necessary to change the filter more frequently.
