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.

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.
Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked to certain
forms of cancer. If you live in an area where you must fill your own gas tank, take precautions.
