system. Repeated use of leaded gasoline will lessen the effectiveness of the emission con-trol system and could result in loss of emissionwarranty coverage. State and local vehicleinspection programs will make detection ofmisfueling easier, possibly resulting in emis-sion test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an octane enhancing additive calledmethyl-cyclopentadienyl manganese tricar-bonyl (MMT). If such fuels are used, yourEmission Control System performancemay be affected, and the Check EngineLight (malfunction indicator light) locatedon your instrument panel may light. If thisoccurs, please return your vehicle to atrained and qualified Volvo service techni-cian 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. To
meet seasonal air quality standards, someareas require the use of "oxygenated" fuel. Volvo permits the use of the following "oxy- genated" fuels. However, the specified octaneratings must still be met.
Alcohol - Ethanol
Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred toas Ethyl alcohol, or "Gasohol". Ethers - MTBE/ETBE: Fuels containing up to 22% MTBE/ETBE by volume may be used.
MethanolDo not use gasolines containing methanol(methyl alcohol, wood alcohol). This practicecan result in vehicle performance deteriorationand can damage critical parts in the fuel sys-tem. Such damage may not be covered underthe New Vehicle Limited Warranty.

NOTE
Extreme weather conditions, towing a trailer, high altitude and lower fuel gradethan recommended are factors that cansignificantly increase the vehicle's fuel con-sumption.
Trailer weights
WARNING
Please adhere to the recommendations provided for trailer weight. If the recom-mendations are not followed, the vehicleand trailer may be difficult to control duringevasive maneuvers and braking.
NOTE
The specified maximum trailer weights are those permitted by Volvo. National vehicleregulations may set additional restrictionson trailer weight and speed. The trailerhitches may be certified for higher towingweights than the vehicle is permitted totow.
Self-leveling suspension *The vehicle's self-leveling system attempts to keep the vehicle at a constant level, regardlessof load (up to the maximum permitted weight).When the vehicle is stationary, the rear end of the vehicle will be slightly lowered, which isnormal.
Driving in hilly terrain or hot weatherIn certain conditions, there is a risk of over-heating when driving with a trailer. If overheat-ing of the engine and drive system is detected,a warning symbol will illuminate in the instru-ment panel and a message will appear. The automatic transmission selects the opti- mal gear for the current load and enginespeed.
Steep inclines
Do not lock the automatic transmission into a higher gear than what the engine can handle
‒
it is not always preferable to drive in highgears at low rpm.
Parking on a hill
1. Depress the brake pedal.
2. Apply the parking brake.
3. Put the gear selector in P.
4. Release the brake pedal.Put chocks behind the wheels when the vehi- cle is parked on a hill with a trailer attached.
Starting on a hill
1. Depress the brake pedal.
2. Put the gear selector in D.
3. Release the parking brake.
4. Release the brake pedal and start driving.

Emission Design and Defect Warranty
Emission Performance Warranty
These are federal warranties; other warrantiesare provided as required by state/provinciallaw. Refer to your separate Warranty andService Records Information booklet fordetailed information concerning each of thewarranties.
Periodic maintenance helps minimize emissions
NOTE
Refer to your Service and Warranty Booklet for a comprehensive serviceand maintenance schedule up to240,000 km (150,000 miles). Thisprogram contains inspections and ser-vices necessary for the proper functionof your vehicle and includes compo-nents that affect vehicle emissions.
The Warranty and Service RecordsInformation booklet also containsdetailed information concerning thewarranties that apply to your vehicle.
On-board Diagnostic SystemOBD 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 temporary.OBD II will store a message about any fault.
Emission inspection readiness
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 was lit,but went out without any action on yourpart, OBD II will still have a recorded fault.Your vehicle may pass or fail, dependingon the inspection practices in your area.
If you had recent service that required dis-connecting the battery, OBD II diagnosticinformation may be incomplete and "notready" for inspection. A vehicle that is notready may fail inspection.

MAINTENANCE AND SERVICE

How can I prepare for my next OBD II
emission inspection?
If your Check Engine (MIL) light is lit or was lit but went out without service, haveyour 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.Two half-hour trips of mixed stop-and-go/highway driving are 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.
Owner maintenancePeriodic 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 maintenance services.
Each time the vehicle 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 loose ter-minal connector, or a battery near the endof its useful service life. Consult your Volvoretailer for additional information.
As needed:
Wash the vehicle, including the undercarriage, to reduce wear that can be caused by abuildup of dirt, and corrosion that can becaused by salt residues. Clean leaves and twigs from air intake vents at the base of the windshield, and from other pla-ces where they may collect.
