•
Fuel consumption is increased at high speeds - air resistance increases with speed.
• Remove unnecessary items from the vehicle- the heavier the load, the higher the fuelconsumption.
• Maintain the correct pressure in the tires andcheck pressure regularly.
• The type of tires used could affect fuel con-sumption - consult a retailer for advice onsuitable tires.
• Do not use winter tires after the winter sea-son has ended.
• Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
• Avoid driving with the windows open.
• Using the trip computer's fuel consumptionindicators can help you learn how to drivemore economically.
Other factors that decrease fuel
consumption
• Dirty air cleaner.
• Dirty engine oil and clogged oil filter.
• Incorrect front-end alignment.
• Incorrect wheel alignment.
Some of the above items and others are checked as part of Volvo's standard maintenance sched-ule.

Preparing for a long trip
It is important to have the vehicle's systems and equipment checked carefully before driving longdistances.
Check that:
• the engine is running properly and that fuel consumption is normal
• there are no leaks (fuel, oil or other fluid)
• the brake pedal is functioning optimally
• all lights are working
‒
adjust the headlight
height if the vehicle is carrying a heavy load
• tire tread depth and air pressure are at cor-rect levels. Change to snow tires when driv-ing in areas where there is a risk of snowy oricy roads.
• the start battery is sufficiently charged
• the wiper blades are in good condition

MAINTENANCE AND SERVICE

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 can thenread "faults." In some states, this type of inspec-tion has replaced the tailpipe emission test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspection for any of the following reasons:
• If your Check Engine (MIL) light is lit, yourvehicle may fail inspection.
• If your vehicle's Check Engine light was lit,but went out without any action on your part,OBD II will still have a recorded fault. Yourvehicle may pass or fail, depending on theinspection 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.
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, have your vehicle diagnosed and, if necessary, servicedby a qualified Volvo technician.
• If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, a periodof driving is necessary to bring the OBD IIsystem to "ready" for inspection. Two half-hour trips of mixed stop-and-go/highwaydriving are typically needed to allow OBD II toreach readiness. Your Volvo retailer can pro-vide you with more information on planning atrip.
• Maintain your vehicle in accordance with yourvehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and intervalsare described in your vehicle's Warranty andService Records Information booklet. The following points can be carried out between the normally scheduled maintenance services.
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 a softcloth.
• Visually inspect battery terminals for corro-sion. Corrosion may indicate a loose terminalconnector, or a battery near the end of itsuseful service life. Consult your Volvo retailerfor additional information.
As needed:
Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup ofdirt, and corrosion that can be caused by salt res-idues. Clean leaves and twigs from air intake vents at the base of the windshield, and from other placeswhere they may collect.
