indicate a fault.
Important
Before you operate your car for the first time please familiarize yourself with the new-engine oil consumption
information on page 131
. You should also be familiar with the information in the chapters one, two and four of
this manual.
Information contained in the balance of the manual is extremely useful and should be read after operating the
vehicle for the first time.
The manual is structured so that it can be used for reference. For this reason, it should be kept in the car for
ready access.
Do not export your Volvo to another country before investigating that country's applicable safety and exhaust
emission requirements. In some cases it may be difficult or impossible to comply with these requirements.
Modifications to the emission control system(s) may render your Volvo not certifiable for legal operation in the
U.S., Canada and other countries.
All information, illustrations and specifications contained in this manual are based on the latest product
information available at the time of publication. Please note that some vehicles may be equipped differently,
depending on special legal requirements and that optional equipment described in this manual may not be
available in all markets.
Volvo reserves the right to make model changes at any time, or to change specifications or design, without
notice and without incurring obligation.
Volvo and the environment
Volvo is committed to the well being of our customers. As a natural part of this commitment, we care about the
environment in which we all live. Caring for the environment means an everyday involvement in reducing our
environmental impact.
Volvo's environmental activities are based on a holistic view, which means we consider the overall environmental
impact of a product throughout its complete life cycle. In this context, design, production, product use, and recycling
are all important considerations.
In production, Volvo has partly or completely phased out several chemicals including freons, lead chromates,
naphtanates, asbestos, mercury and cadmium; and reduced the amount of chemicals used in our plants 50% since 1991.
In use, Volvo was the first in the world to introduce into production a three-way catalytic converter with a Lambda
sond, now called oxygen sensor, in 1976. The current version of this highly efficient system reduces emissions of
harmful substances (CO, HC, NOx) from the exhaust pipe by approximately 95% and the search to eliminate the
remaining emissions continues. Volvo is the only automobile manufacturer to offer CFC-free retrofit kits for the air
conditioning system for all models as far back as the M/Y 1975 240. Advanced electronic engine controls, refined
purification systems and cleaner fuels are bringing us closer to our goal.
After Volvo cars and parts have fulfilled their use, recycling is the next critical step in completing the life cycle. The
metal content is about 75% of the total weight of a car, which makes the car among the most recycled industrial
products. In order to have efficient and well controlled recycling, many Volvo variants have printed dismantling
manuals, indicating the weight and material of individual components. For Volvo, all homogeneous plastic parts
weighing more than 1.7 oz. (50 grams) are marked with international symbols that indicate how the component is to be
sorted for recycling.

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.

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

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.

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.
Recirculation
Recirculation can be used to shut out stale air, exhaust, etc. from the passenger compartment. The air in the passenger
compartment is then recirculated, i. e. no air from outside the car is taken into the car when this function is activated.
Recirculation (together with the air conditioning system) cools the passenger compartment more quickly in warm
weather.
If you allow the air in the car to recirculate, there is a risk of icing and fogging, especially in winter. The timer function
minimizes the risk of ice, misting and stale air.
Activate the timer function as follows:
Press for more that 3 seconds. the LED flashes for 5 seconds. the air recirculates in the car for 3-12 minutes
depending on the outside temperature.
The timer function is activated each time you press .
To switch off the timer function :
Press again for more than 3 seconds. The LED lights for 5 seconds to confirm your selection.
Recirculation is always disconnected when you select Defroster
.

pg. 89 Driving economy
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal
operating temperature.
Drive carefully and avoid rapid acceleration and hard braking.
Do not exceed posted speed limits.
Avoid carrying unnecessary items (extra load) in the car.
Maintain correct tire pressure. Check tire pressure regularly (when tires are cold).
Remove snow tires when threat of snow or ice has ended.
Note that roof racks, ski racks, etc., increase air resistance and also fuel consumption.
Avoid using automatic transmission kickdown feature unless necessary.
Avoid using the air conditioning when it is not required. When engaged, the conditioner's compressor places an
additional load on the engine. However, at higher driving speeds, fuel consumption will be lower with the air
conditioning on and the windows closed than with the air conditioning off and the windows open.
Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease gas mileage are:
Worn or dirty spark plugs
Incorrect spark plug gap
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment Some of the above mentioned items and others are checked at the standard
Maintenance Service intervals.
