Snow chainsUsing snow chains and/or snow tires can help improve traction in winter driving condi-tions.
Volvo does not recommend use of snow chains on wheel dimensions larger than18 inches.
WARNING
Use Volvo genuine snow chains or equiva- lent snow chains that are suitable for thevehicle model and the tire and wheel sizes.Only one-sided snow chains are permit-
ted. If uncertain about snow chains, Volvo rec- ommends contacting an authorized Volvoworkshop. Use of the wrong snow chainscould cause serious damage to the vehicleand result in an accident.
CAUTION
Snow chains can be used on the vehicle, with the following restrictions:
Always follow the manufacturer'sinstallation instructions carefully. Installchains as tightly as possible andretighten periodically.
Only put snow chains on the frontwheels (also applies to all-wheel drivevehicles).
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, sus-pension and body components mustbe maintained.
Check local regulations regarding theuse of snow chains before installing.
Never exceed the snow chain manu-facturer's specified maximum speedlimit. Under no circumstances shouldyou exceed 50 km/h (30 mph).
Avoid bumps, holes or sharp turnswhen driving with snow chains.
Avoid driving on surfaces withoutsnow as this wears out both the snowchains and the tires.
The handling of the vehicle can be adversely affected when driving withchains. Avoid fast or sharp turns aswell as 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.

LOADING, STORAGE AND PASSENGER COMPARTMENT
* Option/accessory.
538
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.

Loading recommendations
There are a number of things that are impor- tant to consider when carrying loads in or onthe vehicle.
Load-carrying capacity is determined by the vehicle's curb weight. The total weight of allpassengers and any installed accessoriesreduces the vehicle's load-carrying capacity bythe corresponding amount.
WARNING
The vehicle's driving characteristics change depending on the weight and position ofthe load.
Loading the cargo compartment/trunkKeep the following in mind when loading:
Position objects so they are pressing against the rear seat backrests.
Heavy objects should be positioned as lowas possible. Avoid placing heavy objectson folded-down seat backrests.
Cover sharp corners with a soft cloth orsimilar to help prevent damage to theupholstery.
Use the load anchoring eyelets and ten-sioning straps or similar to secure allobjects.
WARNING
In a head-on collision at a speed of 50 km/h (30 mph), an unsecured objectweighing 20 kg (44 pounds) can reach aprojectile weight equivalent to 1000 kg(2200 pounds).
WARNING
If objects are loaded higher than the upper edge of the side windows, leave a 10 cm(4 in.) space between the objects and thewindow. Objects placed closer to thiscould impede the function of the inflatablecurtain concealed inside the headlining.
WARNING
Always secure the load. Otherwise, it may shift during heavy braking and injure peo-ple in the vehicle. Cover sharp edges and sharp corners with something soft. Turn off the engine and apply the parking brake when loading/unloading longobjects. Otherwise, it is possible for theload to reach the gear lever or gear selectorand move it to a drive position – whichcould cause the vehicle to begin rolling.

MAINTENANCE AND SERVICE
544
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 asoft cloth.
Visually inspect battery terminals for cor-rosion. Corrosion may indicate a loose ter-minal connector, or a battery near the endof its useful service life. Consult your Volvoretailer for additional information.
As needed:
Wash the vehicle, including the undercarriage, to reduce wear that can be caused by abuildup of dirt, and corrosion that can becaused by salt residues. Clean leaves and twigs from air intake vents at the base of the windshield, and from other pla-ces where they may collect.

Data transfer between vehicle and workshop over Wi-Fi
Volvo workshops have a designated Wi-Fi network for data transfer between your vehi-cle and the workshop. Your visit to the work-shop will be easier and more effective whendiagnostics information and software can betransferred over the workshop's network.
At the workshop, your service technician can connect your vehicle to the workshop's Wi-Finetwork to perform troubleshooting anddownload software. For this type of communi-cation, the vehicle only connects to a work-shop's network. It is not possible to connectthe vehicle to another Wi-Fi network (e.g. yourhome network) in the same way as to a work-shop's network.
Connecting with remote keyConnection is usually managed by the servicetechnician, who will use the remote key but-tons. It is therefore important to bring a keywith buttons with you when you visit theworkshop. Pressing the lock button on theremote key three times will connect the vehi-cle to the workshop's Wi-Fi network. When the car is connected to a Wi-Fi net- work, the
symbol appears in the center
display.
