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

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

NOTE
Volvo does not recommend the use of exter-nal fuel injector cleaning systems.

Unleaded fuel
Each Volvo has a three-way catalytic converterand must use only unleaded gasoline. U.S. andCanadian regulations require that pumps deliver-ing unleaded gasoline be labeled "UNLEADED".Only these pumps have nozzles which fit yourvehicle's filler inlet. It is unlawful to dispense lea-ded fuel into a vehicle labeled "unleaded gaso-line only". Leaded gasoline damages the three-way catalytic converter and the heated oxygensensor system. Repeated use of leaded gasolinewill lessen the effectiveness of the emission con-trol system and could result in loss of emissionwarranty coverage. State and local vehicle
inspection programs will make detection of mis-fueling easier, possibly resulting in emission testfailure 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 allows the use of the following "oxygen-ated" fuels; however, the octane ratings listedmust 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: Fuels containing up to15% MTBE 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.

Opening/closing the fuel filler door
The fuel tank has a filling system that does nothave a cover.

Opening/closing the fuel filler door
An arrow next to the fuel pumpsymbol in the instrument panelindicates the side of the vehiclewhere the fuel filler door islocated.
1. Press the button on the lighting panel.
>Pressure equalization in the fuel tank cau-ses a slight delay before the fuel fillerdoor opens. Fuel tank Fuel lid isopening will be displayed in the instru-ment panel, followed by Fuel tank Readyfor refueling.
2.After refueling, close the fuel filler door bypressing lightly.
Refueling from a service station pump
To refuel:
1.Open the fuel filler door. Do not refuel with
the engine running1
2. Insert the pump's nozzle into the fuel fillerpipe's opening as far as possible (see theillustration).
3. Avoid overfilling the fuel tank. Do not pressthe handle on the filler nozzle after it hasstopped pumping. Too much fuel in the tankin hot weather conditions can cause the fuelto overflow. Overfilling could also cause dam-age to the emission control systems.
1If 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.

Emission controls
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
or location or removing components, and/orrepeated use of leaded fuel.

NOTE
Unleaded fuel is required for vehicles withthree-way catalytic converters.

Heated oxygen sensors
The heated oxygen sensors monitor the oxygencontent 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.

Driving with a trailer
When towing a trailer, always observe the legalrequirements of the state/province.
•All Volvo models are equipped with energy-absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par-ticular problems, but take into consideration:
•Increase tire pressure to recommended fullpressure.
•When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
•Maximum speed when towing a trailer:50 mph (80 km/h).
•Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.
•If the automatic transmission begins to over-heat, a message will be displayed in the textwindow.
•Avoid overload and other abusive operation.
•Hauling a trailer affects handling, durability,and economy.
•It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safestop (check and observe state/local regula-tions).
•Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
•More frequent vehicle maintenance isrequired.
•Remove the ball holder when the hitch is notbeing used.

NOTE
•When parking the vehicle with a trailer ona hill, apply the parking brake before put-ting the gear selector in P. Always followthe trailer manufacturer's recommenda-tions for wheel chocking.
•When starting on a hill, put the gearselector in D before releasing the parkingbrake.
•If you use the manual (Geartronic) shiftpositions while towing a trailer, make surethe gear you select does not put toomuch strain on the engine (using toohigh a gear).
•The drawbar assembly/trailer hitch maybe rated for trailers heavier than the vehi-cle is designed to tow. Please adhere toVolvo's recommended trailer weights.
•Avoid driving with a trailer on inclines ofmore than 15%.

CAUTION
The maximum trailer weights listed are onlyapplicable for altitudes up to 3,280 ft(1000 m) above sea level. With increasingaltitude the engine power and therefore thecar's climbing ability are impaired because ofthe reduced air density, so the maximumtrailer weight has to be reduced accordingly.The weight of the vehicle and trailer must bereduced by 10% for every further 3,280 ft(1,000 m) (or part thereof). When towing5,000 lbs (2,250 kg) hill inclination is restric-ted to 14%.
WARNING
•Bumper-attached trailer hitches must notbe used on Volvos, nor should safetychains be attached to the bumper.
•Trailer hitches attaching to the vehiclerear axle must not be used.
•Never connect a trailer's hydraulic brakesystem directly to the vehicle brake sys-tem, nor a trailer's lighting system directlyto the vehicle lighting system. Consultyour nearest authorized Volvo retailer forcorrect installation.
•When towing a trailer, the trailer's safetychains or wire must be correctly fastenedto the attachment points provided in thetrailer hitch on the vehicle. The safetychain or wire must never be fastened toor wound around the towing ball.
