WARNING
•The vehicle must never be driven with more than one "Temporary spare" tiremounted.
• Driving with a spare wheel may alter thedriving characteristics of the vehicle.Replace the spare wheel with a normalwheel as soon as possible.
• The spare wheel is smaller than the nor-mal wheel, which affects the vehicle'sground clearance. Watch for high curbsand do not wash the vehicle in an auto-matic car wash when a spare wheel ismounted.
• Follow the manufacturer's recommendedtire inflation pressure for the spare wheel.
• On all-wheel drive vehicles, the drive onthe rear axle can be disconnected.
• If the spare wheel is mounted on thefront axle, snow chains must not be used.
• The spare wheel must not be repaired.
CAUTION
The vehicle must not be driven with wheels of different dimensions or with a spare tire otherthan the one that came with the vehicle. Theuse of different size wheels can seriouslydamage your vehicle's transmission.
This illustration is general. The shape and design of the foam block may vary depending on vehicle model.

7. Connect the electrical cable to the nearest
12 V outlet and start the vehicle.
NOTE
Make sure that none of the vehicle's other 12 V sockets are used while the compressoris running.
WARNING
Never leave children unattended in the vehicle while the engine is running. 8. Start the compressor by moving the switch to
the I (On) position.
WARNING
Never stand next to a tire being inflated with the compressor. If cracks, bulges, etc. form onthe tire, switch off the compressor immedi-ately. The vehicle should not be driven. Callroadside assistance to have the vehicle towedto a workshop for inspection/replacement ofthe tire. Volvo recommends an authorizedworkshop.
NOTE
When the compressor first starts, air pressure may temporarily increase up to 6 bar (88 psi)but should decrease again after approxi-mately 30 seconds.
9. Inflate the tire for 7 minutes.
CAUTION
To help avoid overheating, the compressor should never be used for more than10 minutes at a time.
10. Switch off the compressor and check the
inflation pressure using the air pressure gauge. The inflation pressure should bebetween 1.8 bar (22 psi) and 3.5 bar(51 psi). If the inflation pressure is too high,use the air release valve to release air.
WARNING
If the bottle is not removed in the correct order, sealant could spill out.
WARNING
If pressure falls below 1.8 bar (22 psi), the hole in the tire may be too large. The vehicleshould not be driven. Call roadside assistanceto have the vehicle towed to a workshop forinspection/replacement of the tire. Volvo rec-ommends an authorized workshop.
11. Switch off the compressor and remove the electrical cable.
12. Unscrew the hose from the tire's valve and screw the valve cap back on.
13. Put the protective hose cover onto the hose to help prevent leakage of any residual seal- ing compound. Return the equipment to thecargo compartment.

55414. Immediately drive the vehicle at least 3 km
(2 miles) at a maximum speed of 80 km/h (50 mph) to allow the sealing compound toseal the tire, and then recheck the inflationpressure.
NOTE
During the tire's first revolution, some sealing compound may spray out of the puncturehole.
WARNING
Before driving away, make sure that no one is near the vehicle who could be sprayed withsealing compound. Make sure no one iswithin 2 meters(7 feet) of the vehicle.
15. Rechecking the inflation pressure Connect the hose to the tire's valve and screw the hose connector onto the valve asfar as possible. The compressor must beswitched off. 16. Check the inflation pressure on the air pres-
sure gauge.
• If the pressure is under 1.3 bar (19 psi),the tire is not sufficiently sealed. The vehi-cle should not be driven. Call roadsideassistance to have the vehicle towed.
• If the inflation pressure is higher than1.3 bar (19 psi), the tire must be inflatedto the inflation pressure specified on thetire pressure decal on the driver's sidedoor pillar (1 bar = 100 kPa = 14.5 psi). Ifthe inflation pressure is too high, use theair release valve to release air.
NOTE
Replace the sealing compound bottle and hose after use. Volvo recommends havingthese replaced by an authorized Volvo work-shop.
WARNING
Check inflation pressure regularly.
Volvo recommends driving to the nearest author- ized Volvo workshop to have the tire replaced/repaired. Inform the workshop that the tire con-tains sealing compound.
WARNING
After using the tire sealing system, the vehicle should not be driven farther than approxi-mately 200 km (120 miles).
NOTE
The compressor is an electric device. Follow local regulations for disposal.

Determining the vehicle's permittedweight
Properly loading your vehicle will provide maxi- mum return of vehicle design performance.
Weight designationsBefore loading your vehicle, familiarize yourself with the following terms for determining yourvehicle's weight ratings, with or without a trailer,from the vehicle's Federal/Canadian Motor Vehi-cle Safety Standards (FMVSS/CMVSS) label, andthe vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard equipment. It does notinclude passengers, cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipment. When towing, tow-bar weight is also part of cargo weight.
Permissible axle weight
The maximum allowable weight that can be car- ried by a single axle (front or rear). These num-bers are shown on the Federal/Canadian MotorVehicle Safety Standards (FMVSS/CMVSS) label.The total load on each axle must never exceed itsmaximum permissible weight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
Steps for Determining Correct Load Limit
1. Locate the statement "the combined weight of occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle's plac-ard.
2. Determine the combined weight of the driver and passengers that will be riding in yourvehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and luggage load capacity.For example, if the "XXX" amount equals1400 lbs. and there will be five 150 lb. pas-sengers in your vehicle, the amount of availa-ble cargo and luggage load capacity is 650lbs. (1400 - 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. Thatweight may not safely exceed the availablecargo and luggage load capacity calculatedin Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred to yourvehicle. Consult this manual to determinehow this reduces the available cargo and lug-gage load capacity of your vehicle.
WARNING
• Exceeding the permissible axle weight, gross vehicle weight, or any other weightrating limits can cause tire overheatingresulting in permanent deformation orcatastrophic failure.
• Do not use replacement tires with lowerload carrying capacities than the tires thatwere original equipment on the vehiclebecause this will lower the vehicle's GVWrating. Use only tires with the correct loadcarrying capacity. Consult your Volvoretailer for information.

Cargo compartment The vehicle has a flexible cargo compartment that makes it possible to carry and secure largeobjects.
The cargo compartment capacity can be consid- erably increased by folding down the backrests in the second and third rows
* of seats. To make
loading and unloading easier, the rear section of the vehicle can be raised and lowered using the level control function *. Use the load anchoring
eyelets or grocery bag holders to help secure objects in place, and the retractable cargo com- partment cover * to help conceal objects in the
cargo compartment. The towing eyelet and tire sealing system, or the temporary spare tire *, are located under the
cargo compartment floor.

Loading recommendations
There are a number of things to consider when carrying loads in or on the vehicle.
Load-carrying capacity is determined by the vehi- cle's curb weight. The total weight of all passen-gers and any installed accessories reduces thevehicle's load-carrying capacity by the corres-ponding amount.
WARNING
The vehicle's driving characteristics change depending on the weight and position of theload.
Loading in the trunk and cargo compartment
• Position objects so they are pressing against the rear seat backrests.
• Distribute the load evenly.
• Heavy objects should be positioned as lowas possible. Avoid placing heavy objects onfolded-down seat backrests.
• Cover sharp corners with a soft cloth or simi-lar to help prevent damage to the upholstery.
• Use the load anchoring eyelets and tension-ing straps or similar to secure all objects.

Installing and removing the steel
cargo grid *
The steel cargo grid prevents loads or pets in the cargo compartment from being thrown for-ward into the passenger compartment.
For safety reasons, the steel grid must always be installed and secured correctly.
WARNING
Under no circumstances may a person be in the cargo compartment when the vehicle ismoving. Heavy braking or a collision couldlead to serious injury.
The steel grid consists of the grid itself and two separate mounting brackets. Each of the mount- ing brackets has a screw cover and two plasticsleeves for the grid.
WARNING
The steel cargo grid may only be used in the rear position described here. The ceilingattachment points behind the front seats arenot intended to anchor the steel grid.
WARNING
For safety reasons, the third-row seats

must
be folded down when the steel cargo grid is mounted in the vehicle.
CAUTION
The steel cargo grid and the cargo compart- ment cover cannot be mounted at the sametime.
Installation1. Fold down the rear seats and lift in the steel
grid through one of the rear doors or the tail- gate. The curved (convex) side of the gridshould face toward the cargo compartmentand the hooks on each side of the gridshould face upward. The mounting bracketsand plastic sleeves are not needed in thisstep.
2. Press one of the grid's hooks into the largerhole in the ceiling attachment point (1). Grasp the grid near the hook and pull/push it into the smaller hole (2).
> The hook is now secured in the attach-ment point.
3. Repeat step 2 above to secure the other hook in the attachment point on the opposite side.
WARNING
Make sure the cargo grid's hooks are securely attached in the ceiling attachment points tohelp ensure the grid does not come loose.

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.
