The Federal Clean Air Act requires vehicle manufacturers to furnish written instructionsto the ultimate purchaser to assure the properservicing and function of the components thatcontrol emissions. These services, which arelisted in the "Warranty and Service RecordsInformation" booklet, are not covered by thewarranty. You will be required to pay for laborand material used.
Maintenance
Your Volvo passed several major inspections before it was delivered to you, in accordancewith Volvo specifications. The maintenanceprocedures outlined in the Warranty and Serv-ice Records Information booklet, many ofwhich will positively affect your vehicle's emis-sions, should be performed as indicated. It isrecommended that receipts for vehicle emis-sion maintenance be retained in case ques-tions arise concerning maintenance.

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.

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.

Engine oil For the recommended service intervals and warranties to be applied, an approved engineoil must be used.
Volvo recommends:
If the engine oil is not checked regularly and the level becomes low, this could cause seri-ous engine damage.
CAUTION
To satisfy the requirements for the engine's service intervals, all engines are factory-filled with a specially adapted syntheticengine oil. Great care has been put into thechoice of oil, with consideration given toservice life, startability, fuel consumptionand environmental impact. For the recommended service intervals to apply, an approved engine oil must beused. Only use the prescribed oil grade totop off or change the oil. Otherwise, thereis a risk of the vehicle's service life, starta-bility, fuel consumption and environmentalimpact being affected. Failure to use engine oil of the prescribed grade and viscosity could cause damage toengine-related components. Volvo Car Cor-poration disclaims warranty liability forsuch type of damage. Volvo recommends entrusting oil changes to an authorized Volvo workshop.
Volvo uses different systems to warn if the oil level is too low/high or the oil pressure is low.On engine variants with an oil pressure sensor,
