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 in your Warranty and Service Records Information booklet.
Drive at a constant speed

The heart of the Volvo safety system is the three-point seat belt (a Volvo invention)! In order for the SRS system to
provide the protection intended, seat belts must be worn at all times by everyone in the car.
The SRS system is a supplement to the seat belts.WARNING!
If your car has been subjected to flood conditions (e.g. soaked carpeting/standing water on the floor of the vehicle)
or if your car has become flood-damaged in any way, do not attempt to start the vehicle or put the key in the ignition
before disconnecting the battery (see below). This may cause airbag deployment which could result in personal
injury. Have the car towed to an authorized Volvo retailer for repairs.
Before attempting to tow the car, use the following procedure to override the shiftlock system to move the gear
selector to the neutral position.
Disconnect the battery
Wait at least one minute
Insert the key in the ignition and turn it to position 1
Press firmly on the shiftlock override button (located near the base of the gear selector)
While holding the override button down, move the gear selector from the park position.
WARNING!
Never drive with the airbags deployed. The fact that they hang out can impair the steering of your car. Other safety
systems can also be damaged. The smoke and dust formed when the airbags are deployed can cause skin and eye
irritation in the event of prolonged exposure.

gasoline you buy, check with the service station operator. To meet seasonal air quality standards, some areas require
the use of "oxygenated" fuel.
Volvo allows the use of the following "oxygenated" fuels; however, the octane ratings listed on this page must still be
met.
Alcohol — Ethanol
Fuels containing up to 10% ethanol by volume may be used.
Ethanol may also be referred to as Ethyl alcohol, or "Gasohol".
Ethers — MTBE
Fuels containing up to 15% MTBE may be used.
Refueling
The fuel tank is designed to hold approximately: 16 US gallons (60 liters) with sufficient volume left over to
accommodate possible expansion of the fuel in hot weather.
WARNING!
Never carry a cell phone that is switched on while refueling your vehicle. If the phone rings, this may cause a spark
that could ignite gasoline fumes, resulting in fire and injury.
Fuel filler door
The fuel filler door (on the left rear fender) is unlocked along with the car's central locking system.
Open fuel filler cap slowly during hot weather.
CAUTION:
Do not refuel with the engine running *. Turn the ignition off or to position I. If the ignition is on, an incorrect
reading could occur in the fuel gauge.
After refueling, close the fuel filler cap by turning it clockwise until it clicks into place *.
Avoid spilling gasoline during refueling. Gasoline containing alcohol can cause paint damage that may not be
covered under the New Vehicle Limited Warranty.
Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under the
New Vehicle Limited Warranty.
Do not overfill the fuel tank. Overfilling could damage the emission control system.
* If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine
Lamp may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo original or
approved fuel filler caps.
pg. 64 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 short trips. Short trips do not allow the engine to reach normal operating
temperature.
Drive carefully and avoid rapid acceleration and hard braking.
ProCarManuals.com

Do not exceed posted speed limits.
Avoid carrying unnecessary items (extra load) in the car.
Maintain correct tire pressure. Check tire pressure regularly (check 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 thereby fuel consumption.
Avoid using automatic transmission kick-down feature unless necessary.
Avoid using the air conditioning when it is not required. When engaged, the air conditioner's compressor places an
additional load on the engine. However, please note that fuel consumption is lower with the air conditioning on than it
is when driving with the air conditioning switched off and the windows down.
Utilizing the fuel consumption modes in the Trip Computer can help you "learn" how to drive more economically.
Other factors which 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 : The automatic transmission's ( D)rive position should be used as often as possible to help improve fuel
economy.
WARNING!
It is recommended that tires of the same make and dimensions be used on all four wheels (including the use of
snow tires). Do not use bias ply tires as this will adversely alter vehicle handling characteristics. Maintain correct tire
pressure.
Do not drive with trunk lid open! A warning light in the instrument panel will indicate that the trunk is open.
Poisonous exhaust gases may enter via the open trunk lid. If the trunk lid/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.
pg. 65 Starting the engine
Starting and stopping
1. Fasten the seat belt.
WARNING!
Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can
be depressed completely. Move the seat closer if necessary. Refer to section "front seats".
2. Make sure the gear selector is in the Park position.
3. Without touching the accelerator pedal, turn the ignition key to the starting position. Allow the starter to operate
for up to 5 seconds. Release the key as soon as the engine starts. If the engine fails to start, repeat step 3.
For cold starts at altitudes above 6000 ft (1800 meters), depress the accelerator pedal halfway and turn the key to the
starting position. Release the pedal slowly when the engine starts. Depress the brake pedal and release the parking

Periodic maintenance helps minimize emissions
Periodic maintenance will help keep your vehicle running well. Your Warranty and Service Records Information
booklet provides a comprehensive periodic maintenance schedule up to 150,000 miles (240,000 km) of vehicle service.
The schedule includes components that affect vehicle emissions. This page describes some of the emission-related
components.
Engine air filter
The engine air filter cleans particles from air entering the engine. Replace the engine air filter cartridge with a new one
every 37,500 miles (60,000 km) under normal driving conditions. Replace the cartridge more often when the vehicle is
driven under dirty and dusty conditions. The cartridge cannot be cleaned, and should always be replaced with a new
one.
Fuel filter
ProCarManuals.com

The fuel filter should be replaced at 105,000 miles (168,000 km). The filter is replaced as a complete unit. Replace
more frequently if contaminated fuel is introduced into the tank, or if there is reason to suspect that this has occurred.
Fuel system, including filler cap, tank, lines and connections
The ability of the fuel system to contain hydrocarbons depends upon a leak-free system. Inspect fuel lines every
30,000 miles (48,000 km). Check for proper sealing of the fuel filler cap which contains "O" ring seals.
NOTE: If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine
light (Malfunction indicator) may indicate a fault. However, your vehicle's performance will not be affected. Use only
Volvo original or approved fuel filler caps.
Timing belt
For proper functioning of the vehicle and its emission control systems, the timing belt and belt tensioner must be
replaced every 105,000 miles (168,000 km). Engine damage will occur if the belt fails.
PCV system
(on turbocharged models)
The nipple in the intake manifold and the filter at the end of the PCV hose in the air cleaner should be inspected and
cleaned at 105,000 miles (168,000 km) and thereafter, again at 150,000 mile (240,000 km) intervals.
Spark plugs
The spark plugs should be replaced every 45,000 miles (72,000 km) under normal driving conditions. City driving or
fast highway driving may necessitate replacement sooner.
Under normal driving conditions, spark plugs require no maintenance between replacement intervals. When installing
new plugs, be sure to use the right type and to tighten them correctly. When changing the plugs, clean the terminals
and rubber seals. Also check that the suppressor connectors are in good condition. Cracked or damaged connectors
should be replaced.

pg. 112 Fuel/emissions systems
Fuel system
The fuel system is all-electronic and is microprocessor-controlled. It can continually compensate for variation in
engine load, speed and temperature to give the best economy and power. A mass air flow sensor measures the inducted
air. In this way the system can make instantaneous adjustments for changes in air temperature or density, thus always
assuring the best economy with the lowest possible exhaust emissions.
Heated oxygen sensor
This is an emission control system designed to reduce emissions and improve fuel economy. The heated oxygen sensor
monitors the composition of the exhaust gases leaving the engine. The exhaust gas analysis is fed into an electronic
module. This adjusts the air-fuel ratio to provide optimum conditions for combustion and efficient reduction of the
three major pollutants (hydrocarbons, carbon monoxide and oxides of nitrogen (NOx) by a three-way catalytic
converter.
Crankcase ventilation
The engine is provided with positive crankcase ventilation which prevents crankcase gases from being released into the
atmosphere. Instead, the crankcase gases are admitted to the intake manifold and cylinders.
Evaporative control system
The car is equipped with an evaporative control system which prevents gasoline vapor from being released into the
atmosphere.
The system consists of a fuel tank with filler pipe and cap, a rollover valve, a Fill Limit Vent Valve (FLVV), vapor
vent lines, a charcoal canister, a purge line, a purge control valve and engine connections. In addition, there is a
pressure sensor connected to the fuel tank and a filter -protected Canister Close Valve (CCV) on the atmospheric side
of the canister, for system diagnosis.
The gasoline vapor is channeled through the rollover valve and the FLVV via the vapor vent lines into the charcoal
canister, where it is stored. When the engine is started, the gasoline vapor is drawn from the charcoal canister to the
engine's air intake system and into the combustion process.
NOTE:
If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine light
