Fuel requirements
Deposit control gasoline (detergentadditives)
Volvo recommends the use of detergent gas- oline to control engine deposits. Detergentgasoline is effective in keeping injectors andintake valves clean. Consistent use of depositcontrol gasolines will help ensure good driva-bility and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station oper-ator.
NOTE
Volvo does not recommend the use of external fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic con- verter and must use only unleaded gasoline.U.S. and Canadian regulations require thatpumps delivering unleaded gasoline belabeled "UNLEADED". Only these pumpshave nozzles which fit your vehicle's fillerinlet. It is unlawful to dispense leaded fuelinto a vehicle labelled "unleaded gasolineonly". Leaded gasoline damages the three-way catalytic converter and the heated oxy-gen sensor system. Repeated use of leaded gasoline will lessen the effectiveness of theemission control system and could result inloss of emission warranty coverage. Stateand local vehicle inspection programs willmake detection of misfueling easier, possiblyresulting in emission test failure for misfueledvehicles.
NOTE
Some U.S. and Canadian gasolines con- tain an octane enhancing additive calledmethyl-cyclopentadienyl manganese tri-carbonyl (MMT). If such fuels are used,your Emission Control System perform-ance may be affected, and the CheckEngine Light (malfunction indicator light)located on your instrument panel maylight. If this occurs, please return yourvehicle to a trained and qualified Volvoservice technician for service.
Gasoline containing alcohol and ethers, "Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols orethers. In some areas, state or local lawsrequire that the service pump be marked indi- cating use of alcohols or ethers. However,there are areas in which the pumps areunmarked. If you are not sure whether there isalcohol or ethers in the gasoline you buy,check with the service station operator. Tomeet seasonal air quality standards, someareas require the use of "oxygenated" fuel. Volvo allows the use of the following "oxy- genated" fuels; however, the octane ratingslisted on page 279 must still be met.
Alcohol – EthanolFuels containing up to 10% ethanol by vol- ume may be used. Ethanol may also be refer-red to as Ethyl alcohol, or "Gasohol". Ethers – MTBE: Fuels containing up to 15% MTBE may be used.
MethanolDo not use gasolines containing methanol(methyl alcohol, wood alcohol). This practicecan result in vehicle performance deteriora-tion and can damage critical parts in the fuelsystem. Such damage may not be coveredunder the New Vehicle Limited Warranty.

Opening/closing the fuel cap
G022915
Fuel vapor expands in hot weather. Open the filler cap slowly. After refueling, close the fuel filler cap by turning it clockwise until it clicks into place.
CAUTION
•Do not refuel with the engine running 2
.
Turn the ignition off or to position I. If
the ignition is on, an incorrect reading could occur in the fuel gauge.
• Avoid overfilling the fuel tank. Do notpress the handle on the filler nozzlemore than one extra time. Too muchfuel in the tank in hot weather condi-tions can cause the fuel to overflow.Overfilling could also cause damage tothe emission control systems.
Emission controls
Three-way catalytic converter
•
Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle ifyou detect engine misfire, noticeable lossof power or other unusual operating con-ditions, such as engine overheating orbackfiring. A properly tuned engine will help avoid malfunctions that could dam-age the three-way catalytic converter.
• Do not park your vehicle over combusti-ble materials, such as grass or leaves,which can come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
• Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cat-alytic converter or exhaust system over-heating.
• Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehiclemay be illegal and can cause three-waycatalytic converter or exhaust systemoverheating. This includes: altering fuelinjection settings or components, alteringemission system components or locationor removing components, and/or repea-ted use of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.

If the fuel filler cap is not closed tightly or if the engine is running when the vehicle is refueled, the Check Engine Light (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.
