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.

LOADING, STORAGE AND PASSENGER COMPARTMENT
* Option/accessory.580
Loading recommendations
There are a number of things to consider whencarrying 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 changedepending on the weight and position of theload.

Loading the cargo compartment/trunk
Position objects so they are pressing againstthe 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 upperedge 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 shiftduring heavy braking and injure people in thevehicle.
Cover sharp edges and sharp corners withsomething soft.
Turn off the engine and apply the parkingbrake 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 ski hatch*2 in the rear seat can be foldeddown to carry skis or other long, thin objects.

MAINTENANCE AND SERVICE
586

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.
