Onboard Diagnostic System OBD II is part of your vehicle's computerized engine management system. It stores diagnosticinformation about your vehicle's emission con-trols. It can light the Check Engine light (MIL) if itdetects an emission control "fault." A "fault" is acomponent or system that is not performingwithin an expected range. A fault may be perma-nent or temporary. OBD II will store a messageabout 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 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 diagnostic information 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 yourvehicle 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.

Engine compartment – engine oil
The correct oil must be used for the stated oil change (service) intervals to apply. The oil level on 4-cylinder engines is checked electronically and is checked using a dipstick on5- and 6-cylinder engines.
Checking the engine oil (5- and 6-
cylinder engines)
The oil level should be checked at regular inter- vals, particularly during the period up to the firstscheduled maintenance service.
• See Oil specifications (p. 384) for oil specifi-cations.
• Also, refer to the Warranty and ServiceRecords information booklet for informationon oil change intervals and oil specifications.
CAUTION
•
Not checking the oil level regularly can result in serious engine damage if the oillevel becomes too low.
• Oil that is lower than the specified qualitycan damage the engine.
• Volvo does not recommend the use of oiladditives.
• Always add oil of the same type and vis-cosity as already used.
• Never fill oil above the
MAX mark. This
could cause an increase in oil consump-tion.
• Oil changes should be carried out by atrained and qualified Volvo service techni-cian.

CAUTION
•If necessary, top up the cooling system with Volvo Genuine Coolant/Antifreezeonly (a 50/50 mix of water and anti-freeze).
• Different types of antifreeze/coolant maynot be mixed.
• If the cooling system is drained, it shouldbe flushed with clean water or premixedanti-freeze before it is refilled with thecorrect mixture of water/anti-freeze.
• The cooling system must always be keptfilled to the correct level, and the level must be between the
MIN and MAX
marks. If it is not kept filled, there can be high local temperatures in the enginewhich could result in damage. Checkcoolant regularly!
• Do not top up with water only. Thisreduces the rust-protective and anti-freeze qualities of the coolant and has alower boiling point. It can also causedamage to the cooling system if it shouldfreeze.
• Do not use chlorinated tap water in thevehicle's cooling system.
WARNING
•
Never remove the expansion tank cap while the engine is warm. Wait until theengine cools.
• If it is necessary to top off the coolantwhen the engine is warm, unscrew theexpansion tank cap slowly so that theoverpressure dissipates.

(>280 °C).Replace : The fluid should be replaced according
to the intervals specified in the Warranty and Service Records Information booklet. When driving under extremely hard conditions (mountain driving, etc), it may be necessary toreplace the fluid more often. Consult a trainedand qualified Volvo service technician. Always entrust brake fluid changing to a trained and qualified Volvo service technician.
WARNING
• If the fluid level is below the
MIN mark in
the reservoir or if a brake-related mes- sage is shown in the information display: DO NOT DRIVE . Have the car towed to a
trained and qualified Volvo service techni- cian and have the brake system inspec-ted.
• Dot 4 should never be mixed with anyother type of brake fluid.
Filling
1. Turn and open the cover.
2. Unscrew the reservoir cap and fill the fluid.
The level must be between the MIN and
MAX marks.Engine compartment – power steering fluid

Washing the car
The vehicle should be washed at regular inter- vals since dirt, dust, insects and tar spotsadhere to the paint and may cause damage. Tohelp prevent corrosion, it is particularly importantto wash the car frequently in the wintertime.
The following points should be kept in mind when washing and cleaning the car:
CAUTION
Avoid using car washing detergents with a pH value lower than 3.5 or higher than 11.5.Doing so could result in discoloring of ano-dized aluminum surfaces on e.g., roof rails orthe frames around the side windows.
• Avoid washing your car in direct sunlight. Doing so may cause detergents and wax todry out and become abrasive. To avoidscratching, use lukewarm water to soften thedirt before you wash with a soft sponge, andplenty of sudsy water.
• Bird droppings
: Remove from paintwork as
soon as possible. Otherwise the finish maybe permanently damaged.
• A detergent can be used to facilitate thesoftening of dirt and oil.
• Dry the car with a clean chamois andremember to clean the drain holes in thedoors and rocker panels. •
Tar spots can be removed with tar removerafter the car has been washed.
• A stiff-bristle brush and lukewarm soapywater can be used to clean the wiper blades.Frequent cleaning of the windshield andwiper blades improves visibility considerablyand also helps prolong the service life of thewiper blades.
• Wash off the dirt from the underside (wheelhousings, fenders, etc).
• In areas of high industrial fallout, more fre-quent washing is recommended.
NOTE
When washing the car, remember to remove dirt from the drain holes in the doors and sills.
CAUTION
•
During high pressure washing, the spray mouthpiece must never be closer to thevehicle than 13" (30 cm). Do not sprayinto the locks.
• Dirt, snow, etc., on the headlights canreduce lighting capacity considerably.Clean the headlights regularly, for exam-ple when refueling.
Special moonroof cautions:
• Always close the moonroof and sunshade before washing your vehicle.
• Never use abrasive cleaning agents onthe moonroof.
• Never use wax on the rubber sealsaround the moonroof.
Exterior componentsVolvo recommends the use of special cleaning products, available at your Volvo retailer, forcleaning colored plastic, rubber, or ornamentalcomponents such as chromed strips on the exte-rior of your vehicle.
