General information
Shiftlock
When your car is parked, the gear selector is locked in the (P)ark position. To release the selector from this position,
turn the ignition key to position II (or start the engine), depress the brake pedal, press the button on the front of the
gear selector knob and move the selector from (P)ark.
Keylock
This means that when you switch off the ignition, the gear selector must be in the (P)ark position before the key can be
removed from the ignition switch.
Anti-lock Brake System (ABS)
The ABS system in your car performs a self -diagnostic test when the vehicle first reaches the speed of approximately
12 mph (20 km/h). The brake pedal will pulsate several times and a sound may be audible from the ABS control
module. This is normal.
Fuel filler door
Press the button on the light switch panel (see on page 32
) when the car is at a standstill to unlock the fuel filler door.
Please note that the fuel filler door will remain unlocked until the car is driven again at a a speed of over
approximately 5 mph (8km/h). An audible click will be heard when the fuel filler door relocks.
Fuel filler cap
After refueling, close the fuel filler cap by turning it clockwise until it clicks into place. If this cap is not closed tightly
or if the engine is running when the car is refueled, the Malfunction Indicator Lamp ("Check Engine" light) may

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
ProCarManuals.com

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. 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.

pg. 45 Electronic Climate Control (ECC)
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.
ProCarManuals.com

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 36
for additional information on this function.
CAUTION:
Never use ice scrapers made of metal as they can easily scratch the mirror surface.
pg. 46 Electronic Climate Control (ECC) - manual settings
Recirculation (see also page 47)
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 mode activation: (Cars with Interior Air Quality system have no timer mode) Press and hold the recirculation
button for at least 3 seconds to activate a recirculation timer mode. The amber LED in the recirculation button will
flash 5 times to show that the timer mode is being activated. In the time mode, each time the recirculation button is
pressed, the climate control system will recirculate the air in the passenger compartment for 5 to 12 minutes, depending
on the outside air and then revert back to fresh air.
Timer mode deactivation: Press and hold the recirculation button for at least 3 seconds. The amber LED in the
recirculation button will illuminate steadily for 5 seconds to show a return to "normal" mode.
In normal mode, when the recirculation button is pressed, the climate control system will recirculate the air in the
passenger compartment until the recirculation button is pressed again.
Timer mode memory: If the car is turned off while timer mode is active, timer mode will still be active when the
car is restarted.

Heated front seats (option)
Please see page 36 for more information on this function.
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.
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 orange LED next to the control will light
up) will turn both the blower and the air conditioning off.

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

ProCarManuals.com

Operation:
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
3. Press : the LED MAN comes on. Recirculation is now activated.
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 45.
The filter should be changed at the intervals listed in the Warranty and Service Records Information booklet.
However, if the car is used in a severely contaminated environment, it may be necessary to change the filter more
frequently.

TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified govern-ment test course. For example, a tire graded 150 would wear one and one half (1 1/2) times as
well on the government course as a tire graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and many depart significantly from the norm due to variation in driving habits,
service practices and differences in road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.WARNING!
The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and is not a measure of
cornering (turning) traction.
TEMPERATURE
The temperature grades are AA (the highest), A, B, and C, representing the tire's resistance to the generation of heat
and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C corresponds to a minimum level of performance which all
passenger car tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the minimum required by law. WARNING!
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive
speed, under-inflation, or excessive loading, either separately or in combination, can cause heat buildup and possible
tire failure.
