tank Ready for refueling.
2. Select a fuel approved for use in the vehicle. For more information on approved fuels, see the section on "Gasoline".
3. Insert the pump's nozzle into the fuel filler pipe's opening. There are two flaps justinside the fuel filler pipe and the pump's noz-zle must push both of these flaps openbefore fuel can be added. 4. Avoid overfilling the tank. Do not press the
handle on the filler nozzle again after it hasinitially stopped pumping.
> The fuel tank is now filled.
NOTE
An over-full tank may overflow in hot weather.
CAUTION
Avoid spilling gasoline during refueling. In addition to causing damage to the environ-ment, gasolines containing alcohol can causedamage to painted surfaces, which may notbe covered under the New Vehicle LimitedWarranty.
Refueling from a fuel containerWhen filling from a fuel container, use the funnel provided in a foam block under the floor hatch inthe cargo compartment.
1. Open the fuel filler door.
2. Insert the funnel into the fuel filler pipe'sopening. There are two flaps just inside the fuel filler pipe and the tube section of thefunnel must push both of these flaps openbefore fuel can be added.

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 fuel injector cleaning systems, e.g. do not adddetergent additives to gasoline before or afterrefueling.
Unleaded fuelAll 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 in loss 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 an octane 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 volume may be used. Ethanol may also be referred to asEthyl alcohol, or "Gasohol". Ethers - MTBE/ETBE: Fuels containing up to 15% MTBE/ETBE may be used.
MethanolDo 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.

TOP TIER Detergent GasolineVolvo endorses the use of "TOP TIER Detergent Gasoline" 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 or changing gasoline brands, it may be neces-sary to fill the tank more than once before adifference in engine operation is noticeable.
Fuel FormulationsDo 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 nozzle while 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.
Use of AdditivesWith 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 on
while refueling your vehicle. If the phone rings, this may cause a spark that could ignite gaso-line fumes, resulting in fire and injury.
6 AKI (Anti Knock Index) is an average value of RON (Research Octane Number) and MON (Motor Octane Number) - (RON)+(MON)/2

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 drivingIn demanding driving conditions, e.g. when driving in a hot climates, driving with a trailer or drivingfor longer periods at higher altitudes (mountainlandscapes) than normal, it is recommended switching to a higher octane fuel than AKI 916
or
changing gasoline brand to take full advantage of your car's engine capacity and obtain the opti-mum driving force.

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain engine 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 or location or removing components, and/orrepeated use of leaded fuel.NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen content of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.

Battery drain The electrical functions in the vehicle drain the battery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical current whenthe engine is turned off. Examples of such func-tions are:
• blower
• headlights
• windshield wipers
• audio system (especially at high volume).
If the starter battery voltage is low, a message isshown in the driver display. The vehicle's energy-saving function will then turn off or reduce certainfunctions, such as the blower and/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).
