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
indicate a fault.
WARNING! If your vehicle is involved in an accident, unseen damage may affect your vehicle's driveability and
safety.
Important
Before you operate your car for the first time, please familiarize yourself with the new-engine oil consumption
information on page 159
. You should also be familiar with the information in 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.

CALIFORNIA Proposition 65 Warning
WARNING! Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals
known to the state of California to cause cancer, and birth defects or other reproductive harm. In addition, certain
fluids contained in vehicles and certain products of component wear contain or emit chemicals known to the State
of California to cause cancer, and birth defects or other reproductive harm.
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

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 moonroof (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 moonroof and use the recirculation function for several minutes to enable the air conditioning
to cool the compartment as quickly as possible.
Windows and optional moonroof
The ECC system will function best if the windows and optional moonroof are closed. If you drive with the moonroof
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.
Climate control maintenance
Special tools and equipment are required to maintain and carry out repairs on the climate system. Work of this type
should only be done by a trained and qualified Volvo service technician.
Refrigerant
Volvo cares about the environment. The air conditioning system in your car contains a CFC-free refrigerant - R134a
(HFC134a). This substance will not deplete the ozone layer. The system contains 2.2 lbs (1000 g) R134a and uses
PAG oil.
Climate system blower
The climate system blower will be automatically switched off when the engine is not running (even if the ignition key
is in position I or II) to avoid unnecessary battery drain. To activate the blower, turn the control to the desired setting.
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.

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 40
for additional information on this function.
CAUTION:
Never use ice scrapers made of metal as they can easily scratch the mirror surface.

Recirculation (see also page 55)
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 timer mode, each time the recirculation button is
pressed, the climate control system will recirculate the air in the passenger compartment for 5-12 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 40
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

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 51.
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 40
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

Blower
Blower speed can be increases or decreased by turning the knob. If the knob is set to 0, the air conditioning function is
automatically disengaged.
Temperature
Turn the control to set the temperature for the driver's and passenger's sides of the car. For cooler air, the air
conditioning function must be engaged.
Air distribution
Use the air distribution control positions (marked with dots) between the different symbols to fine-tune air distribution
for the maximum comfort.

If a fault should occur in the system, the LED in the button will be switched off and a message will be displayed in the
text window.
Cleaning the sensors
For the system to function properly, the sensors in the front and/or rear bumpers should be kept clean. They can be
cleaned with car washing detergent and a sponge.
WARNING!
These systems are designed to be a supplementary aid when parking the vehicle. They are not, however, intended to
replace the driver's attention and judgement.
pg. 101 Driving economy, Handling
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 fuel consumption.
Avoid using automatic transmission kickdown feature unless necessary.
Avoid using the air conditioning when it is not required. When engaged, the A/C 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:
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.
NOTE: Vehicles equipped with automatic transmissions should use (D)rive as often as possible and avoid using
"kick -down" to help improve fuel economy. Vehicles equipped with manual transmissions should use fifth gear at
highway speeds. At other times, choose the highest gear that still allows smooth acceleration.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore, check that the tires are inflated to
the recommended pressure according to the vehicle load. See "Tire pressure" section. Loads should be distributed so
that capacity weight or maximum permissible axle loads are not exceeded.
Speed-sensitive power steering
(Option on certain models)
ProCarManuals.com

With this feature, the steering is most responsive at lower speeds to make parking, driving in city traffic, etc., easier.
The effect of the power steering diminishes as you accelerate for greater stability at highway speeds.
Weight distribution affects handling
At the specified curb weight your car has a tendency to understeer, which means that the steering wheel has to be
turned more than might seem appropriate for the curvature of a bend. This ensures good stability and reduces the risk
of rear wheel skid. Remember that these properties can alter with the vehicle load. The heavier the load on the rear of
the vehicle (e.g., heavily loaded (max. 220 lbs, 100 kg) cargo area or when towing a trailer, the less the tendency to
understeer.
pg. 102 Points to remember
Cooling system
The risk for engine overheating is greatest, especially in hot weather, when:
Towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm.
Stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
To avoid overheating, the following rules should be followed:
Do not drive for prolonged periods at engine speeds above 4500 rpm if you are towing a trailer in hilly terrain.
Reduce speed when towing a trailer up long, steep inclines. The risk of overheating can be reduced by switching off
the air conditioning system for a short time.
Do not let the engine idle unnecessarily for prolonged periods.
Do not mount auxiliary lamps in front of the grill.
When the risk of overheating is imminent, or in the event of overheating (the temperature gauge goes repeatedly into,
or stays continually in, the red section), the following precautions should be taken:
Switch off the air conditioning system.
Pull off the road, away from traffic, stop the car and put the gear selector into neutral.
Switch the heater to full (maximum) position. Increase the engine speed to approx. 2000 rpm (twice idling speed)
until the temperature begins to drop.
WARNING!
Do not remove coolant expansion tank cap. The coolant will be extremely hot.
If necessary, see page 154
for information on checking and topping-up the coolant level.
CAUTION: Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.). Damage to the
engine could result if excess water is drawn in through the air intake system. Never drive the vehicle in water deeper
than 1 foot (300 mm). See the flood warning on page 5
.
WARNING!
Driving with the tailgate open : Driving with the tailgate open could mean that poisonous exhaust gases enter the
passenger compartment.
If the tailgate must be kept open for any reason, proceed as follows:
- Close the windows.
- Set the ventilation system to air flow to floor, windshield and side windows and blower control to its highest
setting.
Floor mats : An extra mat on the driver's floor can cause the accelerator pedal to catch. Check that the movement
