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.

• Replacing distributor ignition compo- nents e.g. plugs, coil, etc.
• Do not touch any part of the distributorignition system while the engine is run-ning. This may result in unintendedmovements and body injury.

WARNING
•Never expose the battery to open flame or electric spark.
• Do not smoke near the battery.
• Battery fluid contains sulfuric acid. Donot allow battery fluid to contact eyes,skin, fabrics or painted surfaces. Ifcontact occurs, flush the affected areaimmediately with water. Obtain medi-cal help immediately if eyes are affec-ted.
NOTE
The life of the battery is shortened if it becomes discharged repeatedly.
Maintenance
•
Use a screw driver to open the caps or cover and a flashlight to inspect the level.
• If necessary, add distilled water. The levelshould never be above the indicator.
• The fluid level should be checked if thebattery has been recharged.
• After inspection, be sure the cap overeach battery cell or the cover is securelyin place.
• Check that the battery cables are cor-rectly connected and properly tightened. •
Never disconnect the battery when theengine is running, or when the key is inthe ignition. This could damage the vehi-cle's electrical system.
• The battery should be disconnected fromthe vehicle when a battery charger isused directly on the battery.
• To help keep the battery in good condi-tion, the vehicle should be driven for atleast 15 minutes a week or connected toa charger with an automatic chargingfunction.
• If the battery is fully discharged a numberof times, this may shorten its service life.Keeping the battery fully charged helpsprolong its service life.
• The service life of a battery is affected byfactors such as driving conditions and cli-mate. Extreme cold may also furtherdecrease the battery’s starting capacity.
• Because the battery’s starting capacitydecreases with time, it may be necessaryto recharge it if the vehicle is not drivenfor an extended period of time or if thevehicle is usually only driven short dis-tances.
CAUTION
•Always use distilled or deionized water (battery water).
• Never fill above the level mark in thecell.
