Recommended tire pressure
The tire pressure placard on the driver's side B pillar (between the front and the rear door) indi-cates tire pressure for different loads and speedconditions.
The placard specifies the designation for the fac- tory-mounted tires on the vehicle, as well as loadlimits and inflation pressures.

Tire pressure monitoring system
*
The tire pressure monitoring system, Tyre Pressure Monitoring System (TPMS), provides awarning symbol in the instrument panel if pres-sure is too low in one or more tires.
SymbolExplanation
This symbol illuminates to indicate low inflation pressure. If there is a system malfunction, the inflation pressure warning symbolwill flash for approximately oneminute and then glow steadily.
System descriptionThe tire pressure monitoring system measures differences in rotational speed between thewheels through the ABS system to determine ifthe tires are properly inflated. If inflation pressure in a tire is too low, its diameter (and consequently its rotational speed) changes. By comparing thetires with each other, the system can determine ifthe pressure in one or more tires is too low.
General information about the tire pressure
monitoring system
In the following description, the tire monitoring system is generally referred to as TPMS. Each tire, including the spare tire (if provided) 6
,
should be checked monthly when cold and infla- ted to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard ortire inflation pressure label. (If your vehicle hastires of a different size than the size indicated onthe vehicle placard or tire inflation pressure label,you should determine the proper tire inflationpressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires issignificantly under-inflated. Accordingly, when thelow tire pressure telltale illuminates, you shouldstop and check your tires as soon as possible,and inflate them to the proper pressure. Driving on a significantly under-inflated tire cau- ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note thatthe TPMS is not a substitute for proper tire main-tenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under-infla-tion has not reached the level to trigger illumina-tion of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The TPMS mal-function indicator is combined with the low tirepressure telltale. When the system detects a mal-

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
578If 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.

•
Wash using a sponge, car washing detergent and plenty of lukewarm water.
• Clean the wiper blades with lukewarm soapsolution or car washing detergent.
• Dry the vehicle using a clean, soft chamois ora squeegee. Try not to let drops of water dryin strong sunlight. This could cause waterdrying stains that may need to be polishedout.
• In areas with heavy industrial emissions,more frequent washing of the vehicle's exte-rior is recommended.
• Tar spots from asphalt may remain even afterwashing. Use a tar remover to remove thesespots after washing the vehicle.
WARNING
Always entrust engine washing to a workshop. If the engine is hot, there is a risk of fire.
CAUTION
Dirty headlights do not work as well. Clean them regularly, e.g. when refueling. Do not use corrosive cleaners. Use water and a non-abrasive sponge.
NOTE
Exterior lighting such as headlights and tail- lights may develop temporary condensationon the inside of the lens. This is normal. Allexterior lighting is designed to resist this.Condensation is normally vented out of thelamp housing once the light has been lit forsome period of time.
CAUTION
• Make sure that the panoramic roof and sun shade are closed before washing thevehicle.
• Never use abrasive polishing agents onthe panoramic roof.
• Never use wax on the rubber sealsaround the panoramic roof.
CAUTION
Remember to remove dirt from the drain holes in the doors and sills after washing thevehicle.
