kept in its storage compartment under the cargo compartment floor.
The jack provided with your vehicle isintended to be used only in temporarysituations such as changing wheels inthe event of a flat tire. Only the jackthat came with your particular modelshould be used to lift the vehicle. If thevehicle needs to be lifted more fre-quently or for a prolonged period, usinga garage jack or hoist is recommended.Always follow this device's instructionsfor use.
WARNING
Apply the parking brake and put the gear selector in the Park (
P) position.
Block the wheels standing on theground, use rigid wooden blocks orlarge stones.
Check that the jack is not damaged,the threads are properly lubricated andit is free from dirt.
Be sure the jack is on a firm, level, non-slippery surface and that it is uprightand not leaning.
The jack must correctly engage in thejack attachment.
No objects should be placed betweenthe base of the jack and the ground, orbetween the jack and the attachmentbar on the vehicle.
Never let anyone remain in the vehiclewhen it is raised on a jack.
If a tire must be changed near passingtraffic, make sure all passengers moveto a safe location.
Use a jack intended for the vehiclewhen changing a tire. For any otherjob, use stands to support the vehicle.
Never crawl under or allow any part ofyour body to be extended under a vehi-cle supported by a jack. 1. Turn on the vehicle's hazard warning
flashers if a wheel change must be per-formed in an area with traffic.
2. Apply the parking brake and put the gear selector in P, or first gear if the vehicle has
a manual transmission. For vehicles with

CAUTION
Snow chains can be used on the vehicle, with the following restrictions:
Always follow the manufacturer'sinstallation instructions carefully. Installchains as tightly as possible andretighten periodically.
Only put snow chains on the frontwheels (also applies to all-wheel drivevehicles).
If accessory, aftermarket or "custom"tires and wheels with different dimen-sions than the original tires and wheelsare used, snow chains in some casesmay NOT be used. Sufficient distancebetween the chains and brakes, sus-pension and body components mustbe maintained.
Check local regulations regarding theuse of snow chains before installing.
Never exceed the snow chain manu-facturer's specified maximum speedlimit. Under no circumstances shouldyou exceed 50 km/h (30 mph).
Avoid bumps, holes or sharp turnswhen driving with snow chains.
Avoid driving on surfaces withoutsnow as this wears out both the snowchains and the tires.
The handling of the vehicle can be adversely affected when driving withchains. Avoid fast or sharp turns aswell as locked wheel braking.
Some types of strap-on chains affectbrake components and therefore mustNOT be used.
Consult a Volvo retailer for more information about snow chains.

LOADING, STORAGE AND PASSENGER COMPARTMENT

* Option/accessory.585
Loading recommendations
There are a number of things that are impor- tant to consider when carrying loads in or onthe vehicle.
Load-carrying capacity is determined by the vehicle's curb weight. The total weight of allpassengers and any installed accessoriesreduces the vehicle's load-carrying capacity bythe corresponding amount.
WARNING
The vehicle's driving characteristics change depending on the weight and position ofthe load.
Loading the cargo compartment/trunkKeep the following in mind when loading:
Position objects so they are pressing against the rear seat backrests.
Heavy objects should be positioned as lowas possible. Avoid placing heavy objectson folded-down seat backrests.
Cover sharp corners with a soft cloth orsimilar to help prevent damage to theupholstery.
Use the load anchoring eyelets and ten-sioning straps or similar to secure allobjects.
WARNING
In a head-on collision at a speed of 50 km/h (30 mph), an unsecured objectweighing 20 kg (44 pounds) can reach aprojectile weight equivalent to 1000 kg(2200 pounds).
WARNING
If objects are loaded higher than the upper edge of the side windows, leave a 10 cm(4 in.) space between the objects and thewindow. Objects placed closer to thiscould impede the function of the inflatablecurtain concealed inside the headlining.
WARNING
Always secure the load. Otherwise, it may shift during heavy braking and injure peo-ple in the vehicle. Cover sharp edges and sharp corners with something soft. Turn off the engine and apply the parking brake when loading/unloading longobjects. Otherwise, it is possible for theload to reach the gear lever or gear selectorand move it to a drive position – whichcould cause the vehicle to begin rolling.
Extra cargo space
The rear seat backrests can be folded down to increase cargo space in the cargo compart- ment/trunk and simplify loading. If the rearseat backrests are folded down, make surethat no objects loaded into the vehicle preventthe WHIPS system for the front seats fromfunctioning correctly.
Raising/lowering the rear end of the
vehicle *
The rear end of the vehicle can be lowered orraised for easier loading into the cargo com-partment/trunk or to facilitate attaching a trailer*.
The controls for raising/lowering are located at the rear edge of the right side panel in thecargo compartment/trunk.

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, 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 theOBD II system to "ready" for inspection.Two half-hour trips of mixed stop-and-go/highway driving are typically needed toallow OBD II to reach readiness. YourVolvo retailer can provide you with moreinformation on planning a trip.
Maintain your vehicle in accordance withyour vehicle's maintenance schedule.
Owner maintenancePeriodic 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 maintenance services.
Each time the vehicle 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 asoft cloth.
Visually inspect battery terminals for cor-rosion. Corrosion may indicate a loose ter-minal connector, or a battery near the endof its useful service life. Consult your Volvoretailer for additional information.
As needed:
Wash the vehicle, including the undercarriage, to reduce wear that can be caused by abuildup of dirt, and corrosion that can becaused by salt residues. Clean leaves and twigs from air intake vents at the base of the windshield, and from other pla-ces where they may collect.
