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.
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.
In addition to continuous environmental refinement of conventional gasoline-powered internal combustion engines,
Volvo is actively looking at advanced technology alternative-fuel vehicles.
When you drive a Volvo, you become our partner in the work to lessen the car's impact on the environment.
To reduce your vehicle's environmental impact, you can:
· Maintain proper air pressure in your tires. Tests have shown decreased fuel economy with improperly inflated tires
· Follow the recommended maintenance schedule
· Drive at a constant speed
· See an authorized Volvo retailer as soon as possible for inspection if the check engine (malfunction indicator) lamp
illuminates, or stays on after the vehicle has started
· Properly dispose of any vehicle related waste such as used motor oil, used batteries, brake pads, etc.
· When cleaning your car, use Volvo's own car care products, all of which have systematically been adapted to the
environment

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.

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 function: (Cars with Interior Air Quality system have no 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 orange LED next to the control will light
up) will turn both the blower and the air conditioning off.

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 36 for more information on this function.
pg. 47 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

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.
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.
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.
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.
pg. 87 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 125 and 128
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 7
.
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 control 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 of
the accelerator pedal is not impeded. Not more than one protective floor covering may be used at one time.
Electrical system
When replacing the battery or when carrying out work involving the electrical system, the following should be
observed:
A battery connection to the wrong terminal will damage the electrical system. Be sure to connect the positive battery
cable to the positive battery terminal and the negative battery cable to the negative battery terminal.
If booster batteries are used for starting, they must be properly connected to minimize the risk of the electrical
system being damaged. For correct connection, see "Jump starting" section.
Never disconnect the battery circuit (for example, to replace the battery) while the engine is running, as this may
damage the generator. Always make sure that all the battery connections are properly cleaned and tightened.
If any electrical welding work is performed on the vehicle, the battery's ground lead (negative cable) and all the
connecting cables of the generator must be disconnected and the welder cables placed as near the welding points as
possible.
The radio must be turned off before the battery is disconnected.
Switch off the ignition for at least 10 minutes before disconnecting the battery.
