Snow tires
Snow tires are designed for winter driving conditions.
Volvo recommends snow tires with specific dimensions. The tire dimensions vary depend-ing on engine type. When driving with snowtires, the correct type of tires must be moun-ted on all four wheels.
NOTE
Contact a Volvo dealer for advice on the best choice of rims and tires.
Tips for changing snow tiresWhen switching between regular tires and snow tires, mark the tires according to whichside they were mounted on, e.g. L for left and
R for right.
Studded tiresStudded tires should be broken in by driving500–1000 km (300–600 miles) slowly andgently to help the studs settle properly in thetires. This gives the tire, and especially thestuds, a longer service life.
NOTE
Regulations regarding the use of studded tires vary from country to country.
Tread depthRoad conditions with ice, slush and low tem- peratures place considerably higher demandson tires than summer conditions. Volvo there-fore recommends not driving on snow tiresthat have a tread depth of less than 4 mm(0.15 inch).

Snow chains
Using 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.

Using the electrical outlets
The 12 V outlet can be used for devices intended for this such as MP3 players, cool-ers and cellular phones.
The ignition must be in at least mode I for the
outlets to supply current. The outlets will then be active as long as there is sufficient chargein the start battery. If the engine is turned off and the vehicle is locked, the outlets will be deactivated. If theengine is turned off and the vehicle remainsunlocked, the sockets will remain active for upto 7 minutes.
NOTE
Bear in mind that using the electrical out- lets when the engine is off could cause thestarter battery to have too low of a chargelevel, which could limit other functionality. Accessories connected to the electrical outlets can be activated even when thevehicle electrical system is off or if precon-ditioning is used. For this reason, discon-nect plugs when they are not in use to pre-vent the starter battery from becoming dis-charged.

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.
