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.
The spare wheel is located in the spare wheel well with the outside of the wheel facing down-ward. The same bolt runs through both the sparewheel and foam block to hold them into place.The foam block contains all tools needed tochange a wheel.

CAUTION
Snow chains can be used on the vehicle, with the 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 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 trunk.

* Option/accessory.543
Cargo compartment Loads can be secured in the trunk to keep them in place while driving.
The folding* rear seat backrests can help
increase the cargo capacity of the trunk. Load anchoring eyelets and grocery bag holders areprovided to help secure objects in place. The towing eyelet and tire sealing system, or the temporary spare tire *, are located under the
cargo compartment floor.

• Grocery bag holders (p. 544)
• Load anchoring eyelets (p. 545)
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.
WARNING
In a head-on collision at a speed of 50 km/h (30 mph), an unsecured object weighing 20kg (44 pounds) can reach a projectile weightequivalent to 1000 kg (2200 pounds).
WARNING
If objects are loaded higher than the upper edge of the side windows, leave a 10 cm (4in.) space between the objects and the win-dow. Objects placed closer to this couldimpede the function of the inflatable curtainconcealed inside the headlining.
WARNING
Always secure the load. Otherwise, it may shift during heavy braking and injure people in thevehicle. Cover sharp edges and sharp corners with something soft. Turn off the engine and apply the parking brake when loading/unloading long objects.Otherwise, it is possible for the load to reachthe gear lever or gear selector and move it toa drive position – which could cause the vehi-cle to begin rolling.

Extra cargo space
The rear seat backrests can be folded down * to
increase cargo space in the trunk and simplify loading. If the rear seat backrests are foldeddown, make sure that no objects loaded into thevehicle prevent the WHIPS system for the frontseats from functioning correctly. The ski hatch * in the rear seat can be folded
down to carry skis or other long, thin objects.

Roof loads and load carriers Volvo-developed load carriers are recommended for carrying loads on the roof of the vehicle.
Volvo load carriers are specially designed to help prevent 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. •Check periodically to ensure that the load carriers and load are properly secured.Secure the load firmly using tie straps orsimilar.
• Distribute the load evenly throughout theload carriers. Place heavier cargo at the bot-tom of the load.
• 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 driving characteristics are altered by roof loads. Follow the vehicle's specifications regarding weights and maximum permitted load.
