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

As an enhancement to the three-point seat belt system, your Volvo is equipped with a Supplemental Restraint System
(SRS). The Volvo SRS consists of an airbag (2) on both the driver's and passenger's sides and seat belt tensioners in
both front door pillars (4). The system is designed to supplement the protection provided by the three-point seat belt
system.
The SRS system is indicated by the "SRS" embossed on the steering wheel pad and above the glove compartment, and
by decals on both sun visors and on the far right side of the dash.
The airbags are folded and located in the steering wheel hub and above the glove compartment. They are designed to
deploy during certain frontal or front -angular collisions, impacts, or decelerations, depending on the crash severity,
angle, speed and object impacted. The airbags may also deploy in certain non-frontal collisions where rapid
deceleration occurs.
The airbag system includes gas generators (1) surrounded by the airbags (2) and front seat belt tensioners for both of
the front seats (4). To deploy the system, the sensor (3) activates the gas generators causing the airbags to be inflated
with nitrogen gas. As the movement of the seats' occupants compresses the airbags, some of the gas is expelled at a
controlled rate to provide better cushioning. Both seat belt tensioners also deploy, minimizing any seat belt slack.
The entire process, including inflation and deflation of the airbags, takes approximately two-tenths of a second.WARNING!
· As its name implies, SRS is designed to be a SUPPLEMENT to - not a replacement for - the three-point belt
system. For maximum protection, wear seat belts at all times. Be aware that no system can prevent all possible
injuries that may occur in an accident.
· When installing any optional equipment, make sure that the SRS system is not damaged. Do not attempt to service
any component of the SRS yourself. Attempting to do so may result in serious personal injury. If a problem arises,
take your car to the nearest authorized Volvo retailer for inspection as soon as possible.

A self -diagnostic system incorporated in the sensor monitors the SRS. The system, however, does not monitor the
SIPS airbags. If a fault is detected, the "SRS" warning light will illuminate. The light is included in the
warning/indicator light cluster in the instrument panel. Normally, the SRS warning lamp should light up when the
ignition is switched on and should go out after 5 seconds or when the engine is started. Check that this light is
functioning properly every time the car is started.
The following items are monitored by the self -diagnostic system:
· Sensor unit
· Cable harness
· Gas generator igniters WARNING!
Never drive an SRS equipped car with your hands on the steering wheel pad / airbag housing.
No objects, accessory equipment or stickers may be placed on, attached to or installed near the SRS cover in the
center of the steering wheel, the SRS cover above the glove compartment or the area affected by airbag deployment.
If the SRS warning light stays on after the engine has started or if it comes on while you are driving, drive the car to
the nearest authorized Volvo retailer for inspection as soon as possible.
The above is a sample of the label found on all seat belts equipped with tensioners, located on the front seat belts near the lower anchorage point.

WARNING!
Do not use child safety seats or child booster cushions/backrests in the front passenger's seat. We also recommend
that children who have outgrown these devices sit in the rear seat with the seat belt properly fastened.
NOTE: Deployment of SRS components occurs only one time during an accident. In a collision where deployment
occurs, the air bags and seat belt tensioners activate. Some noise occurs and a small amount of powder is released. The
release of the powder may appear as smoke-like matter. This is a normal characteristic and does not indicate fire.
NOTE: NOTE: Volvo's dual-threshold air bags use special sensors that are integrated with the front seat buckles. The
point at which the air bag deploys is determined by whether or not the seat belt is being used, as well as, the severity of
the collision. Collisions can occur where only one of the airbags deploys.
WARNING!
· Children must never be allowed in the front passenger seat. Volvo recommends that ALL occupants (adults and
children) shorter than 4 feet 7 inches (140 cm) be seated in the back seat of any vehicle with a front passenger side

airbag. See page 10 for guidelines.
· Occupants in the front passenger's seat must never sit on the edge of the seat, sit leaning toward the instrument
panel or otherwise sit out of position. The occupant's back must be as upright as comfort allows and be against the
seat back with the seat belt properly fastened.
· Feet must be on the floor, e.g. not on the dash, seat or out of the window.
· No objects or accessory equipment, e.g. dash covers, may be placed on, attached to or installed near the SRS hatch
(the area above the glove compartment) or the area affected by airbag deployment (see illustration).
· There should be no loose articles, e.g. coffee cups, on the floor, seat or dash area.
· Never try to open the SRS cover on the steering wheel or the passenger side SRS hatch. This should only be done
by an authorized Volvo service technician.
· Failure to follow these instructions can result in injury to the vehicle occupants in an accident.

NOTE: The information on this page does not pertain to the Side Impact Protection System airbags.
When are the airbags deployed?
The SRS system is designed to deploy during certain frontal or frontangular collisions, impacts, or decelerations,
depending on the crash severity, angle, speed and object impacted. The SRS sensor is designed to react to both the
impact of the collision and the inertial forces generated by it and to determine if the intensity of the collision is
sufficient for the airbags to be deployed.
WARNING!
The SRS is designed to help prevent serious injury. Deployment occurs very quickly and with considerable force.
During normal deployment and depending on variables such as seating position, one may experience abrasions,
bruises, swellings, or other injuries as a result of airbag(s) deployment.
If the airbags have been deployed, we recommend the following:
· Have the car towed to an authorized Volvo retailer. Never drive with the airbags deployed.
· Have an authorized Volvo retailer replace the SRS system components.
· Use only new, Genuine Volvo Parts when replacing SRS components (airbags, seat belts, tensioners, etc.).
When are the airbags NOT deployed?
Not all frontal collisions activate the SRS system. If the collision involves a nonrigid object (e.g., a snow drift or
bush), or a rigid, fixed object at a low speed, the SRS system will not necessarily deploy. Airbags do not normally
deploy in a side impact collision, in a collision from the rear or in a rollover situation. The amount of damage to the
bodywork does not reliably indicate if the airbags should have deployed or not.

If the light comes on while driving or braking, stop immediately, open the hood and check the brake fluid level
in the reservoir. See page 117
for reservoir position.
Canadian models are equipped with this warning light:
WARNING!
If the fluid level is below the MIN mark in either section of the reservoir: DO NOT DRIVE. Tow the car to a Volvo
retailer and have the brake system checked and any leakage repaired.
Parking brake reminder light
This light will be on when the parking brake (hand brake) is applied. The parking brake lever is situated between the
front seats.
Canadian models are equipped with this warning light:
pg. 19 Warning lights
STC disengaged (option)
The indicator light in the instrument panel will be ON when you have switched the Stability and Traction Control
system (STC) OFF using the button on the dashboard (see page 23).
The light will also come on if there is a fault in the
STC system or to indicate that the brakes have overheated. The light will go out when the brake temperature returns to
normal.
The symbol will flash when STC is actively regulating power to the drive wheels. Normal power may be reduced at
this time. This is normal as power is momentarily reduced to help keep the drive wheels from losing traction and
spinning.
Anti-lock Brake system (ABS)
If the warning lamp lights up there is a malfunction of the ABS system (the standard braking system will however
function). The vehicle should be driven to a Volvo retailer for inspection.
See page 69 for additional information.
Canadian models are equipped with this warning light:
Coolant level sensor
If this light comes on while driving, the coolant level is low. The coolant level in the expansion tank should be
checked immediately and topped up if necessary. The cooling system should be inspected by an authorized Volvo
retailer.

Checking your engine oil level each time the car is refueled is one of the most important items you can perform to
help keep your car in good running order.
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be efficient
in keeping injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good
driveability and fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with
the service station operator.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian regulations
require that pumps delivering unleaded gasoline be labelled "UNLEADED". Only these pumps have nozzles which fit
your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "unleaded gasoline only". Leaded
gasoline damages the three-way catalytic converter and the heated oxygen sensor system. Repeated use of leaded
gasoline will lessen the effectiveness of the emission control system and could result in loss of emission warranty
coverage. State and local vehicle inspection programs will make detection of misfueling easier, possibly resulting in
emission test failure for misfueled vehicles.
NOTE: Some U.S. and Canadian gasolines contain an octane enhancing additive called methly-cyclopentadienyl
manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected,
and the Malfunction Indicator Lamp located on your instrument panel may light. If this occurs, please return your
vehicle to an authorized Volvo retailer for service.
pg. 57 Fuel requirements, Refueling
Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating. AKI of 91,
or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane
Number, MON. (RON + MON/2).
The minimum octane requirement is AKI 87 (RON 91).
Gasoline containing alcohol and ethers
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols or ethers. In some areas, state or
local laws require that the service pump be marked indicating use of alcohols or ethers. However, there are areas in
which the pumps are unmarked. If you are not sure whether there is alcohol or ethers in the 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

inspected at 60,000 miles (96,000 km) and thereafter, at 30,000 mile (48,000 km) intervals.
Cabin air filter
Replace the cabin air filter with a new one at 15,000 mile (24,000 km) intervals. Volvo recommends replacing the
filter more often if the car is driven under dirty and dusty conditions. The filter cannot be cleaned and therefore should
always be replaced with a new one.
pg. 110 Fuel/emissions systems
Fuel system
The fuel system is allelectronic and is microprocessorcontrolled. 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 airfuel 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 threeway 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
