CAUTION
Snow chains can be used on the vehicle, with the following restrictions:• Volvo recommends not using snowchains on wheel dimensions larger than19 inches.
• Always follow the manufacturer's installa-tion instructions carefully. Install chainsas tightly as possible and retighten peri-odically.
• Only put snow chains on the front wheels(also applies to all-wheel drive vehicles).
• 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, suspen-sion and body components must bemaintained.
• Check local regulations regarding the useof snow chains before installing.
• Never exceed the snow chain manufac-turer's specified maximum speed limit.Under no circumstances should youexceed 50 km/h (30 mph).
• Avoid bumps, holes or sharp turns whendriving with snow chains.
• Avoid driving on surfaces without snow as this wears out both the snow chains andthe tires.
• The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns as wellas 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.

Tire sealing system12
The temporary tire sealing system can be used to seal a puncture in a tire or to check andadjust the pressure in the tire. Models equipped with a spare wheel 13
do not
have the tire sealing system.
The tire sealing system consists of a compressor and a bottle containing sealing compound. Thesealing functions as a temporary repair.
NOTE
The sealing compound effectively seals tires with punctures in the tread but may not beable to fully seal tires with punctures in thesidewall. Do not use the tire sealing systemon tires with large tears, cracks or similardamage.
NOTE
The compressor is intended for temporary tire sealing and is approved by Volvo.
LocationThe tire sealing system is located in a foam block under the floor of the cargo compartment.

WARNING
Please keep the following points in mind when using the tire sealing system:
• The sealing compound bottle (no. 8 in the illustration) contains 1) rubber latex, natu-ral and 2) ethanediol. These substancesare harmful if swallowed.
• The contents of this bottle may causeallergic skin reactions or otherwise bepotentially harmful to the respiratory tract,the skin, the central nervous system, andthe eyes.
Precautions:
• Keep out of reach of children.
• Do not ingest the contents.
• Avoid prolonged or repeated contact with the skin. Remove any clothing that has come into contact with sealant.
• Wash thoroughly after handling.
First aid: • Skin: Wash affected areas of the skin with soap and water. Get medical atten-tion if symptoms occur.
• Eyes: Flush with plenty of water for least15 minutes, occasionally lifting the upperand lower eyelids. Get medical attention ifsymptoms occur.
• Inhalation: Move the exposed person to fresh air. If irritation persists, get medicalattention.
• Ingestion: Do NOT induce vomitingunless directed to do so by medical per-sonnel. Get medical attention.
• Disposal: Dispose of this material and itscontainer at a hazardous or special wastecollection point.
WARNING
•
Do not remove the bottle while the tire sealing system is being used.
• Do not remove the hose while the tiresealing system is being used.
1. Turn on the vehicle's hazard warning flashers if the tire sealing system is to be used in anarea with traffic. If the puncture was caused by a nail or simi- lar object, do not remove it. It will help sealthe hole.
2. Peel off the speed limit sticker from the side of the compressor. Affix the decal to a clearlyvisible location on the windshield to remindthe driver not to exceed this speed limit. Donot drive faster than 80 km/h (50 mph) whileusing a tire that has been temporarilyrepaired with the tire sealing system. 3.
Make sure the switch is in the 0 (Off) posi-
tion and take out the electric cable and thehose.
4. Unscrew the orange cover on the compres- sor and unscrew the cap on the sealing com-pound bottle.
5. Screw the bottle onto the bottle holder as far as possible. The bottle and the bottle holder are equip- ped with catches to help prevent the sealingcompound from leaking. Once the bottle isscrewed into place into the bottle holder, itcannot be unscrewed. The bottle can only beremoved by a workshop. Volvo recommendsan authorized Volvo workshop.
WARNING
Do not unscrew the bottle. It is equipped with a catch to prevent leakage.
6. Unscrew the tire's valve cap and screw the hose's valve connector as far as possible onto the valve. Be sure the air release valve on the com- pressor's hose is completely closed.

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.

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.
