WARNING
The vehicle must never be driven withmore 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 ofdifferent 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.

CAUTION
Snow chains can be used on the vehicle, withthe following restrictions:
Volvo recommends not using snowchains on wheel dimensions larger than18 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 asthis 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 informationabout snow chains.

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 faras 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 witha catch to prevent leakage.
6. Unscrew the tire's valve cap and screw thehose's valve connector as far as possibleonto the valve.
Be sure the air release valve on the com-pressor's hose is completely closed.
7.Connect the electrical cable to the nearest12 V outlet and start the vehicle.
NOTE
Make sure that none of the vehicle's other12 V sockets are used while the compressoris running.

WARNING
Never leave children unattended in the vehiclewhile the engine is running.

WARNING
Inhaling exhaust fumes could lead to seriousinjury. Never leave the engine running in anenclosed space or a space without sufficientventilation.
8. Start the compressor by moving the switch tothe I (On) position.
WARNING
Never stand next to a tire being inflated withthe 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 pressuremay 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 compressorshould never be used for more than10 minutes at a time.

10. Switch off the compressor and check theinflation pressure using the air pressuregauge. 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 pressure falls below 1.8 bar (22 psi), thehole 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 theelectrical cable.
12.Unscrew the hose from the tire's valve andscrew the valve cap back on.

NOTE
After inflating a tire, always replace thevalve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
13. Put the protective hose cover onto the hoseto help prevent leakage of any residual seal-ing compound. Return the equipment to thecargo compartment.
14. 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 sealingcompound may spray out of the puncturehole.

WARNING
Before driving away, make sure that no one isnear 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 andscrew 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 andhose 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.

Determining the vehicle's permittedweight
Properly loading your vehicle will provide maxi-mum return of vehicle design performance.

Weight designations
Before loading your vehicle, familiarize yourselfwith 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 offuel and all standard equipment. It does notinclude passengers, cargo, or optional equipment.

Capacity weight
All weight added to the curb weight, includingcargo 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 weightof occupants and cargo should never exceedXXX kg or XXX lbs." on your vehicle's plac-ard.
2. Determine the combined weight of the driverand passengers that will be riding in yourvehicle.
3. Subtract the combined weight of the driverand passengers from XXX kg or XXX lbs.
4. The resulting figure equals the availableamount 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 luggageand 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, loadfrom 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.

Monthly:
Check cold tire pressure in all tires. Inspectthe 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, toreduce 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 atthe base of the windshield, and from other placeswhere they may collect.

Data transfer between vehicle andworkshop over Wi-Fi
Volvo workshops have a designated Wi-Fi net-work for secure data transfer between your vehi-cle and the workshop. Your visit to the workshopwill be easier and more effective when diagnos-tics information and software can be transferredover the workshop's network.
When you arrive at the workshop, your servicetechnician can connect your vehicle to the work-shop's Wi-Fi network to perform troubleshootingand download software. For this type of commu-nication, the vehicle only connects to a work-shop's network. It is not possible to connect thevehicle to another Wi-Fi network (e.g. your homenetwork) in the same way as to a workshop's net-work.

Connecting with remote key
Connection is usually managed by the servicetechnician, who will use the remote key buttons. Itis therefore important to bring a key with buttonswith you when you visit the workshop. Pressingthe lock button on the remote key three times willconnect the vehicle to the workshop's Wi-Fi net-work.
When the car is connected to a Wi-Fi network,
the symbol appears in the center display.
