Roof loads and load carriers
Volvo-developed load carriers are recommendedfor carrying loads on the roof of the vehicle.
Volvo load carriers are specially designed to helpprevent damage to your vehicle and help ensuremaximum safety while driving. Volvo load carriersare available from authorized Volvo retailers.
Carefully follow the installation instructions provi-ded with the load carriers.
Distribute the load evenly throughout theload carriers. Place heavier cargo at the bot-tom of the load.
Check periodically to ensure that the loadcarriers and load are properly secured.Secure the load firmly using tie straps orsimilar.
If the load is longer than the vehicle, such asa canoe or kayak, attach the towing eyelet inits front outlet and secure the tie straps in it.
The vehicle's wind resistance and fuel con-sumption increase with the size of the load.
Drive smoothly. Avoid rapid acceleration, hardbraking and fast cornering.

WARNING
The vehicle's center of gravity and drivingcharacteristics are altered by roof loads.
Follow the vehicle's specifications regardingweights and maximum permitted load.

Periodic maintenance helps minimize
emissions
NOTE
Refer to your Service and Warranty Book-let for a comprehensive service and main-tenance schedule up to 240,000 km(150,000 miles). This program containsinspections and services necessary forthe proper function of your vehicle andincludes components that affect vehicleemissions.
The Warranty and Service Records Infor-mation booklet also contains detailedinformation concerning the warrantiesthat apply to your vehicle.

On-board Diagnostic System
OBD II is part of your vehicle's computerizedengine 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 avehicle'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 inspectionfor 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 waslit 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 maintenance

Engine oil
For the recommended service intervals and war-ranties to be applied, an approved engine oilmust be used.
Volvo recommends:
If the engine oil is not checked regularly and thelevel becomes low, this could cause seriousengine damage.

CAUTION
To satisfy the requirements for the engine'sservice 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 toapply, 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 prescribedgrade and viscosity could cause damage toengine-related components. Volvo Car Corpo-ration disclaims warranty liability for such typeof damage.
Volvo recommends entrusting oil changes toan authorized Volvo workshop.
Volvo uses different systems to warn if the oillevel 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 displaymessages 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 tothe 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.
