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.

MAINTENANCE AND SERVICE
588If the engine oil is not checked regularly and the level becomes low, this could cause seriousengine damage.
CAUTION
To satisfy the requirements for the engine's service intervals, all engines are factory-filledwith a specially adapted synthetic engine oil.Great care has been put into the choice of oil,with consideration given to service life, starta-bility, fuel consumption and environmentalimpact. For the recommended service intervals to apply, an approved engine oil must be used.Only use the prescribed oil grade to top off orchange the oil. Otherwise, there is a risk ofthe vehicle's service life, startability, fuel con-sumption and environmental impact beingaffected. Failure to use engine oil of the prescribed grade and viscosity could cause damage toengine-related components. Volvo Car Corpo-ration disclaims warranty liability for such typeof 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. Onengine variants with an oil pressure sensor, a
warning symbol is displayed in the instrument panel when oil pressure is low
. On engine
variants with an oil level sensor, the
warn-
ing symbol in the instrument panel and display messages are used to alert the driver. Someengine variants have both systems. Contact aVolvo retailer for more information. Change the engine oil and oil filter according to the schedule specified in the Warranty and Main-tenance Records Information booklet. Oils of ahigher grade than that specified may be used. Ifthe vehicle is driven in adverse conditions, Volvorecommends using an oil with a higher gradethan that specified.

Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heat trans-ferred from the engine to the coolant can beused to warm the passenger compartment.
When refilling coolant, follow the instructions on the package. Never fill the cooling system withonly water. The risk of freezing is increased withtoo low or too high amounts of coolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than 2 liters (about2 quarts) of coolant has been added to the sys-tem, there could be something wrong with thecooling system and starting the vehicle coulddamage the engine. Call a tow truck and do notattempt to start the engine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.

Polishing and waxingPolish and wax the vehicle when the paint is matte or to provide extra protection. The vehicledoes not need to be polished until it is at least ayear old. However, it can be waxed during thefirst year. Do not polish or wax the vehicle indirect sunlight. The surface of the vehicle shouldnot be warmer than approximately 45 °C(113 °F).
• Wash and dry the vehicle very carefully before polishing or waxing. Remove asphaltand tar stains with asphalt remover or paintthinner. More stubborn stains can beremoved with a grinding paste designed forvehicle paint.
• Use polish first and then liquid or paste wax.Follow the instructions on the package care-fully. Many products contain both polish andwax.
• A wide range of polymer-based waxes canbe purchased today. These waxes are easy touse and produce a long-lasting, high-glossfinish that protects the bodywork against oxi-dation, road dirt and fading.
CAUTION
Avoid waxing and polishing plastic and rubber. If using degreaser on plastic and rubber, only rub (if necessary) with slight pressure. Use asoft sponge. Polishing glossy trim moldings can wear away or damage the glossy surface layer. Polish containing abrasives must not be used.
CAUTION
Only use paintwork treatments recommended by Volvo. Other treatments, such as preserva-tion, sealing, protection, luster sealing or simi-lar, could damage the paintwork. Paintworkdamage caused by such treatments are notcovered by Volvo's warranty.

Hand washing
The vehicle should be washed as soon as it becomes dirty. This makes the vehicle easier toclean because dirt does not attach as strongly. Italso reduces the risk of scratches and keeps thevehicle looking new. Wash the vehicle in a carwash or garage with an oil separator. Use a carwashing detergent.
Hand washingKeep the following points in mind when washing the vehicle:
• Avoid washing the vehicle in direct sunlight.This could cause the detergent or wax to dryout and become abrasive.
• Remove bird droppings from paintwork assoon as possible. They contain chemicalsthat affect and discolor paint very quickly.Use e.g. soft paper or a sponge soaked inlots of water. Consult an authorized Volvoworkshop for assistance removing discolora-tion.
• Hose down the underbody, including thewheel housings and bumper.
• Hose down the entire vehicle and removeany loose dirt, droppings etc. to reduce therisk of scratches from washing. Do not spraydirectly onto locks.
• If necessary, use cold degreaser on heavilysoiled surfaces. Note that in such cases thesurfaces must not be hot from the sun.

Exterior plastic, rubber and trim components
A special cleaning agent available from Volvo retailers is recommended for the cleaning andcare of colored plastic parts, rubber and trimcomponents, e.g. glossy trim. Follow the usageinstructions for the cleaning agent carefully. Avoid using car washing detergents with a pH value lower than 3.5 or higher than 11.5. Doingso could result in the discoloring of anodized alu- minum surfaces* (as shown in the illustrations
below). Abrasive polishing agents are not recom- mended for these areas (as shown in the illustra-tions below).Components that should be washed with a cleaning product with a pH value between 3.5 and 11.5.
CAUTION
Avoid waxing and polishing plastic and rubber. If using degreaser on plastic and rubber, only rub (if necessary) with slight pressure. Use asoft sponge. Polishing glossy trim moldings can wear away or damage the glossy surface layer. Polish containing abrasives must not be used.
CAUTION
Avoid washing the vehicle with cleaner with a pH value below 3.5 or above 11.5. This couldcause discoloration of anodized aluminumcomponents like the roof rail and around theside windows. Never use metal polishing agent on anodized aluminum components. This could cause dis-coloration and destroy the surface treatment.
