pumps have nozzles which fit your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle
labeled "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.
Octane Rating
Volvo recommends the use of unleaded gasoline with an (R+M)/2 octane rating (also called the Anti-
Knock Index, or AKI) of 91 or higher. This is generally equivalent to a Research Octane Number (RON)
of 95 or higher.
The minimum octane requirement is AKI 87 (RON 91).
Turbo models should be run on RON 95 fuel only.
Gasoline Containing Alcohol
Some fuel suppliers sell gasoline containing alcohol without advertising the presence of alcohol. If you
are not sure whether there is alcohol in the gasoline you buy, check with the service station operator.
Blends of unleaded gasoline and ethanol (ethyl alcohol, grain alcohol), sometimes called "gasohol", are
available in some areas. Gasohol, if used, must contain no more than 10 percent ethanol and must have
an (R+M)/2 ratings of 87 or higher. If you experience problems with starting, driveability, or fuel
economy with gasohol, you should discontinue its use.
Take care not to spill gasoline during refueling. Gasolines containing alcohol can cause damage to
painted surfaces, which may not be covered under the New Vehicle Warranty.
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.
Refueling
The fuel tank filler cap is located behind the door on the left rear fender. Open cap slowly during hot
weather conditions.
When filling, position the cap in the special bracket on the door.
After filling the tank, install the cap and turn until a "click" is heard.
