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.
2
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.

Introduction
Volvo recommends the use of Volvo trailer hitches that are specially designed for thevehicle.
NOTE
See page 373 for the maximum trailer and tongue weights recommended by Volvo.
•Observe the legal requirements of the state/province in which the vehicles are
• All Volvo models are equipped withenergy-absorbing shock-mounted bump-ers. Trailer hitch installation should notinterfere with the proper operation of thisbumper system.
Trailer towing does not normally present any particular problems, but take into considera-tion: • Increase tire pressure to recommended full pressure. See the tire inflation tableon page 307.
• When your vehicle is new, avoid towingheavy trailers 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 cool-ant temperature should be closely watched when driving in hot climates orhilly terrain. Use a lower gear and turn offthe air conditioner if the temperaturegauge needle enters the red range.
• If the automatic transmission begins tooverheat, a message will be displayed inthe text window.
• Avoid overload and other abusive opera-tion.
• Hauling a trailer affects handling, durabil-ity, and economy.
• It is necessary to balance trailer brakeswith the towing vehicle brakes to providea safe stop (check and observe state/local regulations).
• 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 isnot being used.
WARNING
• Bumper-attached trailer hitches must not be used on Volvos, nor shouldsafety chains be attached to thebumper.
• Trailer hitches attaching to the vehiclerear axle must not be used.
• Never connect a trailer's hydraulicbrake system directly to the vehiclebrake system, nor a trailer's lightingsystem directly to the vehicle lightingsystem. Consult your nearest author-ized Volvo retailer for correct installa-tion.
• When towing a trailer, the trailer'ssafety wire must be correctly fastenedto the hole or hook provided in thetrailer hitch on the vehicle. The safetywire should never be fastened to orwound around the drawbar ball.

, press START/STOP
ENGINE for approximately 2 seconds to
activate ignition mode II.
2. The remote key must remain in the igni- tion slot 2
for the entire time that the vehi-
cle is being towed.
3. Keep the tow rope taut when the towing vehicle slows down by applying light pressure on the brake pedal. This willhelp prevent jarring movements of thevehicle being towed.
4. Be prepared to apply the brakes to stop the vehicle being towed.CAUTION
General towing precautions:
• Please check with state and local authorities before attempting this typeof towing, as vehicles being towed aresubject to regulations regarding maxi-mum towing speed, length and type oftowing device, lighting, etc.
• If the vehicle's battery is dead, attachjumper cables (see page 123) to pro-vide current for releasing the electricparking brake and to move the gearselector from the
P position to N. If
this is not possible, see page 128 forinformation about manually overridingthe shiftlock system to move the gearselector from P to N.
• Maximum speed: 50 mph (80 km/h).Do not exceed the maximum allowabletowing speed.
• Maximum distance with front wheelson ground: 50 miles (80 km).
• The vehicle should only be towed inthe forward direction.
Having the vehicle towed by a tow truck
Call for professional help from an authorized towing company.Volvo recommends the useof flat bed equipment. The towing eyelet may be used to pull the vehicle onto a flatbed tow truck if:
• The angle of the tow truck’s ramp is not more than 12 degrees from a horizontalplane
• The vehicle’s wheels rotate freely and rollstraight ahead
WARNING
No person or object should be behind the tow truck while the vehicle is being pulledup onto the flatbed.

* Option/accessory, for more information, see Introduction.321
Inflating tires
The tire sealing system can be used to inflate the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.
Ensure that the on/off switch is in position0 (the 0 side of the switch should be
pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire’s inflation valve and screw the hose con- nector onto the valve as tightly as possi-ble by hand.
5. Connect the electrical wire to the nearest 12-volt socket in the vehicle.
6. Start the vehicle’s engine.WARNING
• The vehicle’s engine should be running when the tire sealing system is used toavoid battery drain. Therefore, be surethe vehicle is parked in a well ventilatedplace, or outdoors, before using thesystem. The parking brake should besecurely applied and the gear selectorshould be in the
P (park) position.
• Children should never be left unatten-ded in the vehicle when the engine isrunning.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to get a clear reading from the pressuregauge.
8. Refer to the tire inflation table in this chapter for the correct inflation pressure.If the tire needs to be inflated, start thetire sealing system’s compressor (pressthe on/off switch to position I). If neces-sary, release air from the tire by turningthe air release knob counterclockwise.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoidoverheating.
9. Turn off the compressor (press the on/off switch to position 0) when the correct
inflation pressure has been reached.
10. Unscrew the hose from the tire’s inflation valve and reinstall the valve cap.
CAUTION
•After pumping the tires, always reinstall the valve cap to help avoid damage tothe valve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
11. Disconnect the electrical wire from the
12-volt socket.

08 Wheels and tires
Tire Pressure Monitoring System (TPMS)
08
* Option/accessory, for more information, see Introduction.327
NOTE
• If you change to tires with a different recommended inflation pressure, theTPMS system must be recalibrated tothese tires. On U.S. models, this mustbe done by a trained and qualifiedVolvo service technician. On Canadianmodels, see the following section"Recalibrating TPMS."
• If a tire is changed, or if the TPMS sen-sor is moved to another wheel, thesensor's seal, nut, and valve coreshould be replaced.
• When installing TPMS sensors, thevehicle must be parked for at least15 minutes with the ignition off. If thevehicle is driven within 15 minutes, aTPMS error message will be displayed.
Recalibrating TPMS (Canadian models only)*
In certain cases, it may be necessary to reca- librate TPMS to conform to Volvo's recom-mended tire inflation pressures (see the infla-tion pressure table on page 307), for exam-ple, if higher inflation pressure is necessarywhen transporting heavy loads, etc. This is done in the vehicle's menu system. See page 199 for a description of the menusystem. To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure
and put the ignition in mode I or II (see
page 87 for additional information).
3. Press the MY CAR key in the center con-
sole control panel and select
Settings
Car settingsTyre pressure
4. Press OK/MENU , select Calibrate tyre
pressure and press OK/MENU again.
5. Drive the vehicle at a speed above 25 mph (40 km/h) continuously for at least 10 minutes.
> When the calibration message is nolonger displayed, TPMS has been recalibrated to the new inflation pres-sure.
Activating/deactivating TPMS
(Canadian models only)*
1. Switch off the engine.
2. Put the ignition in mode I or II (see page
87 for additional information).
3. Press the MY CAR key in the center con-
sole control panel and select
Settings
Car settingsTyre pressure
4. Select Tyre pressure system and press
OK/MENU to turn the system on or off.
Self-supporting run flat tires (SST)*
Self-supporting run flat tires are available as optional equipment. The vehicle must beequipped with the Tire Pressure MonitoringSystem (TPMS) if tires of this type are instal-led. Tires of this type have specially reinforced sidewalls that make it possible to continuedriving to a limited extent even though the tirehas lost some or all of its inflation pressure.These tires are mounted on special rims (nor-mal tires can also be mounted on these rims). If an SST tire loses inflation pressure, the yel- low TPMS symbol illuminates in the instru-ment panel and a text message is also dis-played. If this happens, reduce speed to notmore than 50 mph (80 km/h). The tire shouldbe replaced as soon as possible. Drive carefully; it may be difficult to determine which tire is damaged. To find the damagedtire, check the inflation pressure in all fourtires.

Owner maintenance
Periodic maintenance requirements and inter- vals are described in your vehicle's Warrantyand Service Records Information booklet. The following points can be carried out between the normally scheduled maintenanceservices.
Each time the car is refueled:
•Check the engine oil level.
• Clean the windshield, windshield wipers, headlights, and taillights.
Monthly:
• Check cold tire pressure in all tires.Inspect the tires for wear.
• Check that engine coolant and other fluidlevels are between the indicated "min"and "max" markings.
• Clean interior glass surfaces with a glasscleaner and soft paper towels.
• Wipe driver information displays with asoft cloth.
• Visually inspect battery terminals for cor-rosion. Corrosion may indicate a looseterminal connector, or a battery near theend of its useful service life. Consult yourVolvo retailer for additional information.
As needed:Wash the car, including the undercarriage, to reduce wear that can be caused by a buildupof dirt, and corrosion that can be caused bysalt residues. Clean leaves and twigs from air intake vents at the base of the windshield, and from otherplaces where they may collect.
NOTE
Complete service information for qualified technicians is available online for purchaseor subscription at www.volvotechinfo.com.
Hoisting the vehicle
If a garage jack is used to lift the vehicle, the two jack attachments points should be used. They are specially reinforced to bear theweight of the vehicle. A garage jack can alsobe placed under the front of the engine sup-port frame. Take care not to damage thesplash guard under the engine. Ensure thatthe jack is positioned so that the vehicle can-not slide off it. Always use axle stands or sim-ilar structures. If a two-post hoist is used to lift the vehicle, the front and rear lift arm pads should becentered under the reinforced lift plates onthe inboard edge of the sill rail (see illustra-tion).
Emission inspection readiness
What is an Onboard Diagnostic System
(OBD II)?
OBD II is part of your vehicle's computerized engine management system. It stores diag-nostic information about your vehicle's emis-sion controls. It can light the Check Enginelight (MIL) if it detects an emission control"fault." A "fault" is a component or systemthat is not performing within an expectedrange. A fault may be permanent or tempo-rary. OBD II will store a message about anyfault.

How do states use OBD II for emission
inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector canthen read "faults." In some states, this type ofinspection has replaced the tailpipe emissiontest.
How can my vehicle fail OBD II emission inspection?
Your vehicle can fail OBD II emission inspec-tion for any of the following reasons.
• If your Check Engine (MIL) light is lit, your vehicle may fail inspection.
• If your vehicle's Check Engine light waslit, but went out without any action onyour part, OBD II will still have a recordedfault. Your vehicle may pass or fail,depending on the inspection practices inyour area.
• If you had recent service that requireddisconnecting the battery, OBD II diag-nostic information may be incompleteand "not ready" for inspection. A vehiclethat is not ready may fail inspection.
How can I prepare for my next OBD II
emission inspection?
• If your Check Engine (MIL) light is lit – orwas lit but went out without service, have your vehicle diagnosed and, if necessary,serviced by a qualified Volvo technician.
• If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, aperiod of driving is necessary to bring theOBD II system to "ready" for inspection.A half-hour trip of mixed stop-and-go/highway driving is typically needed toallow OBD II to reach readiness. YourVolvo retailer can provide you with moreinformation on planning a trip.
• Maintain your vehicle in accordance withyour vehicle's maintenance schedule.
