Fuel
Volvo recommends the use of detergent gaso-line to control engine deposits.

Deposit control gasoline (gasoline with
detergent additives)
Detergent gasoline is effective in keeping injec-tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddriveability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.

NOTE
Volvo recommends not using external fuelinjector cleaning systems, e.g. do not adddetergent additives to gasoline before or afterrefueling.

Unleaded fuel
All Volvo vehicles have a three-way catalytic con-verter and must only use unleaded gasoline. USand Canadian regulations require that pumpsdelivering unleaded gasoline are labeled"UNLEADED". Only the nozzles of these pumpswill fit in your vehicle's fuel filler inlet. It is unlaw-ful to dispense leaded fuel into a vehicle labeled"unleaded gasoline only". Leaded gasoline dam-ages the three-way catalytic converter and theheated oxygen sensor system. Repeated use ofleaded gasoline will lessen the effectiveness of
the emission control system and could result inloss of emission warranty coverage. State andlocal vehicle inspection programs will makedetection of misfueling easier, possibly resultingin emission test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain anoctane enhancing additive called methyl-cyclopentadienyl manganese tricarbonyl(MMT). If such fuels are used, your EmissionControl System performance may be affected,and the Check Engine Light (malfunctionindicator light) located on your instrumentpanel may light. If this occurs, please returnyour vehicle 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 laws requirethat the service pump be marked indicating useof alcohols or ethers. However, there are areas inwhich the pumps are unmarked. If you are notsure whether there is alcohol or ethers in thegasoline you buy, check with the service stationoperator. To meet seasonal air quality standards,some areas require the use of "oxygenated" fuel.
Volvo permits the use of the following "oxygen-ated" fuels. However, the specified octane ratingsmust still be met.
Alcohol - Ethanol
Fuels containing up to 10% ethanol by volumemay be used. Ethanol may also be referred to asEthyl alcohol, or "Gasohol".
Ethers - MTBE/ETBE: Fuels containing up to22% MTBE/ETBE by volume may be used.

Methanol
Do not use gasolines containing methanol(methyl alcohol, wood alcohol). This practice canresult in vehicle performance deterioration andcan damage critical parts in the fuel system. Suchdamage may not be covered under the NewVehicle Limited Warranty.

Octane rating
Volvo requires premium fuel (91 octane10 orhigher) for all T5, T6 and T8 engines, and rec-ommends AKI 93 for optimal performance andfuel economy. See decal examples in illustra-tions 1 and 2.

TOP TIER Detergent Gasoline
Volvo endorses the use of "TOP TIER DetergentGasoline" where available to help maintainengine performance and reliability. TOP TIERDetergent Gasoline meets a new standard jointlyestablished by leading automotive manufacturesto meet the needs of today's advanced engines.Qualifying gasoline retailers (stations) will, inmost cases, identify their gasoline as having metthe "TOP TIER Detergent Gasoline" standards.

NOTE
Information about TOP TIER Detergent Gaso-line is available at www.toptiergas.com.
NOTE
When switching to higher octane fuel orchanging gasoline brands, it may be neces-sary to fill the tank more than once before adifference in engine operation is noticeable.

Fuel Formulations
Do not use gasoline that contains lead or manga-nese as a knock inhibitor, and do not use leadadditives. Besides damaging the exhaust emis-sion control systems on your vehicle, lead hasbeen strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent.Unburned benzene has been strongly linked tocertain forms of cancer. If you live in an areawhere you must fill your own gas tank, take pre-cautions. These may include:
standing upwind away from the filler nozzlewhile refueling
refueling only at gas stations with vaporrecovery systems that fully seal the mouth ofthe filler neck during refueling
wearing neoprene gloves while handling afuel filler nozzle.
10AKI (Anti Knock Index) is an average value of RON (Research Octane Number) and MON (Motor Octane Number) - (RON)+(MON)/211For supplementary information - see the car's Service and Warranty Booklet.

Use of Additives
With the exception of gas line antifreeze duringwinter months, do not add solvents, thickeners, orother store-bought additives to your vehicle'sfuel, cooling, or lubricating systems. Overuse maydamage your engine, and some of these additivescontain organically volatile chemicals. Do notneedlessly expose yourself to these chemicals.

WARNING
Never carry a cell phone that is switched onwhile refueling your vehicle. If the phone rings,this may cause a spark that could ignite gaso-line fumes, resulting in fire and injury.

WARNING
Carbon monoxide is a poisonous, colorless,and odorless gas. It is present in all exhaustgases. If you ever smell exhaust fumes insidethe vehicle, make sure the passenger com-partment is ventilated, and immediately returnthe vehicle to a trained and qualified Volvoservice technician for correction.

Demanding driving
In demanding driving conditions, such as whentowing a trailer or driving in hot weather or forprolonged periods at high altitudes, it may be agood idea to switch to a higher-octane fuel
(AKI10 91 or higher) or to switch to another
brand of gasoline in order to fully utilize the vehi-cle's engine capacity and optimize traction.

Three-way catalytic converter
Keep your engine properly tuned. Certainengine malfunctions, particularly involving theelectrical, fuel or distributor ignition systems,may cause unusually high three-way catalyticconverter temperatures. Do not continue tooperate your vehicle if you detect enginemisfire, noticeable loss of power or otherunusual operating conditions, such as engineoverheating or backfiring. A properly tunedengine will help avoid malfunctions thatcould damage the three-way catalytic con-verter.
Do not park your vehicle over combustiblematerials, such as grass or leaves, which cancome into contact with the hot exhaust sys-tem and cause such materials to ignite undercertain wind and weather conditions.
Excessive starter cranking (in excess of oneminute), or an intermittently firing or floodedengine can cause three-way catalytic con-verter or exhaust system overheating.
Remember that tampering or unauthorizedmodifications to the engine, the Engine Con-trol Module, or the vehicle may be illegal andcan cause three-way catalytic converter orexhaust system overheating. This includes:altering fuel injection settings or compo-nents, altering emission system components
