areas under the front section of the vehicle, not under to jack attachment points (the outermost points shown in the illustration) .
Rear : Under the jack attachment points.
Ensure that the jack is positioned so that the vehicle cannot slide off it. Always use axlestands or similar structures.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, 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 neededto allow 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.

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).
