Important
Before you operate your car for the first time, please familiarize yourself with the new-engine oil consumption
information on page 122
. 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.
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
ProCarManuals.com

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
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.
PremAir®
On the surface of the radiator in the engine compartment, there is a special coating called PremAir®. PremAir® works
as a catalytic converter, converting most of the ozone passing through the radiator into oxygen, thereby reducing
harmful ground-level ozone.

CHECK
ENGINE
Malfunction indicator lamp
On-Board Diagnostic II (OBDII): As you drive, a computer called "OBDII" monitors your car's engine, transmission,
electrical and emission systems. The CHECK ENGINE light will light up if the computer senses a condition that
potentially may need correcting. When this happens, please have your car checked by a Volvo retailer as soon as
possible.
A CHECK ENGINE light may have many causes. Sometimes, you may not notice a change in your car's behavior.
Even so, an uncorrected condition could hurt fuel economy, emission cleanliness, and driveability. Extended driving
without correcting the cause could even damage other components in your car.
Canadian models are equipped with this warning light:
NOTE : If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Malfunction
Indicator Lamp may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo
original or approved fuel filler caps.

Fuel requirements
Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating AKI of 91,
ProCarManuals.com

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).
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be
effective 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 methyl-cyclopentadienyl
manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected,
and the Check Engine light (malfunction indicator lamp) located on your instrument panel may light. If this occurs,
please return your vehicle to an authorized Volvo retailer for service.
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: 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.
CAUTION!
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.
pg. 71 Fuel requirements
Carbon Monoxide - Important Warning
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaust gases. If you ever smell
exhaust fumes inside the vehicle, make sure the passenger compartment is ventilated, and immediately return the
vehicle to your retailer for correction.
Fuel Formulations
Do not use gasoline that contains lead as a knock inhibitor, and do not use lead additives. Besides damaging the
exhaust emission control systems on your car, lead has been strongly linked to certain forms of cancer.
