It is always worthwhile to have your vehicle checked by a trained and qualified Volvoservice technician before driving long dis-tances. Your retailer or service technician willalso be able to supply you with bulbs, fuses,spark plugs and wiper blades for your use inthe event that problems occur. As a minimum, the following items should be checked before any long trip:• Check that engine runs smoothly and that fuel consumption is normal.
• Check for fuel, oil, and fluid leakage.
• Check transmission oil level 1
.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (the spare tire aswell), and replace those that are worn.Check tire pressures.
• The brakes, front wheel alignment, andsteering gear should be checked by atrained and qualified Volvo service techni-cian only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces. •
Have a word with your Volvo retailer ifyou intend to drive in countries where itmay be difficult to obtain the correct fuel.
• Consider your destination. If you will bedriving through an area where snow or iceare likely to occur, consider snow tires.

properly. Always check the TPMS malfunc- tion telltale after replacing one or more tiresor wheels on your vehicle to ensure that thereplacement or alternate tires and wheelsallow the TPMS to continue to function prop-erly.
NOTE
TPMS indicates low tire pressure but does not replace normal tire maintenance. Forinformation on correct tire pressure, pleaserefer to the tire inflation pressure table inthis chapter or consult your Volvo retailer.
Erasing warning messagesWhen a low tire pressure warning message has been displayed, and the tire pressurewarning light has come on:
1. Use a tire pressure gauge to check theinflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pres- sure (consult the tire pressure placard or the table see page 183).
3. Drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or faster.
> This will erase the warning text and thewarning light will go out.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control ofthe vehicle.
Changing wheels with TPMSPlease note the following when changing or replacing the factory installed TPMS wheels/tires on the vehicle:
• Only the factory-mounted wheels are equipped with TPMS sensors in thevalves.
• If the vehicle is equipped with a tempo-rary spare tire, this tire does not have aTPMS sensor.
• If wheels without TPMS sensors are mounted on the vehicle,
TIRE PRESS
SYST. SERVICE REQUIRED will be dis-
played each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes ormore.
• Once TPMS sensors are properly instal-led, the warning message should notreappear.
• Volvo recommends that TPMS sensorsbe fitted on all wheels used on the vehi-cle. Volvo does not recommend movingsensors back and forth between sets ofwheels.
NOTE
If a tire is changed or if the TPMS sensor is moved to another wheel, the sensor’svalve and valve core should be replaced.
CAUTION
When inflating tires with TPMS valves, press the pump's mouthpiece straightonto the valve to help avoid bending orotherwise damaging the valve.
Recalibrating TPMS (Canadian models only)
In certain cases, it may be necessary to reca- librate TPMS to conform to Volvo's recom-mended tire inflation pressures (see the infla-tion pressure table on page 183), for exam-ple, if higher inflation pressure is necessarywhen transporting heavy loads, etc. To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure
and turn the ignition key to position I or II
(see page 145 for additional information).
3. Turn the thumb wheel on the left-side steering wheel lever until

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 vehicle is refueled
•Check the engine oil level
• Clean the windshield, windshield wipers, headlights, and tail lights
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 atrained and qualified Volvo service techni-cian for additional information.
As needed
•
Wash the vehicle, including the undercar-riage, to reduce wear that can be causedby a buildup of dirt, and corrosion thatcan be caused by salt residues.
• Clean leaves and twigs from air intakevents at the base of the windshield, andfrom other places where they may collect.
• Complete service information for qualifiedtechnicians is available online for pur-chase or subscription at www.volvote-chinfo.com.
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 avehicle's OBD II system. The inspector can then 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 the

Battery maintenance
The battery in your vehicle is located under the floor of the cargo compartment. Driving habits and conditions, climate, the number of starts, etc. all affect the service lifeand function of the battery. In order for yourbattery to perform satisfactorily, keep the fol-lowing in mind:
• 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 to a 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.
