All Wheel Drive (AWD) 11
Your Volvo can be equipped with All Wheel Drive, which means that power is distributedautomatically between the front and rear wheels.
Under normal driving conditions, most of the engine's power is directed to the front wheels.However, if there is any tendency for the frontwheels to spin, an electronically controlled cou-pling distributes power to the wheels that havethe best traction. AWD reacts differently, depending on the drive mode * selected.

Suspension and leveling control
*
The leveling control system adjusts the suspen- sion and shock absorbers automatically to helpprovide good comfort and control while driving.Leveling can also be controlled manually tomake loading or getting in and out of the vehicleeasier.
Pneumatic suspension and shock absorbers
This system is linked to the selected drive mode and is adapted to the vehicle's speed. The pneu-matic suspension reduces the vehicle's groundclearance at higher speeds to reduce wind resis-tance and increase stability. The shock absorbersare normally set to provide the best possiblecomfort and are adjusted continuously accordingto the road surface, acceleration, braking andcornering. A message will be displayed in the instrument panel when the suspension level is beingadjusted. The level cannot be adjusted if one of the side doors or the hood is open.
Suspension leveling settings
Easy entryThe vehicle can be lowered to entering and exit- ing easier. Select
SettingsVehicleEasy Entry/Exit
Control via the center display's Top view to lower
the vehicle when getting in or out. When the vehicle is parked and the engine is turned off, the level is lowered (if a side door isopened, the level adjustment will stop). When theengine is started and the vehicle begins to move,the level will be raised to the height set by theselected drive mode.

Loading modeUse the buttons in the cargo compartment to raise or lower the vehicle to make loading orunloading easier or when attaching a trailer.
Parking the vehicleWhen parking, be sure that there is adequatespace above and below the vehicle since itsground clearance may vary, e.g., depending onthe ambient temperature, how the vehicle is loa-ded, if loading mode is being used or the drivemode selected after the engine is started. The level may also be adjusted for a certain time after the vehicle has been parked to compensatefor possible height adjustments due to tempera-ture changes in the pneumatic suspension whenthe vehicle has cooled.
TransportWhen transporting the vehicle on a ferry, train ora tow truck, it may only be secured (lashed)around the tires, not using any other chassiscomponents. Changes in the pneumatic suspen-sion may occur during transport that could nega-tively affect the lashing and result in damage.

WHEELS AND TIRES
473
Snow tires and chains
The use of snow chains and/or winter tires can help improve traction in winter driving conditions.
Snow chains can be used on your Volvo with the following restrictions:
• Snow chains should be installed on front wheels only. Use only Volvo approved snowchains.
• If accessory, aftermarket or "custom" tiresand wheels are installed and are of a size dif-ferent than the original tires and wheels,chains in some cases CANNOT be used.Sufficient clearances between chains andbrakes, suspension and body componentsmust be maintained.
• Some strap-on type chains will interfere withbrake components and therefore CANNOTbe used.
• All Wheel Drive models
: Snow chains
should only be installed on the front wheels.
• Certain size tires may not allow the assemblyof snow chains/traction devices.
Consult your Volvo retailer for additional snow chain information.
CAUTION
• Snow chains should not be used on wheels larger than 19".
• Always follow the chain manufacturer'sinstallation instructions carefully. Installchains as tightly as possible andretighten periodically.
• Check local regulations regarding the useof snow chains before installing.
• Use single-sided snow chains only.
• Never exceed the chain manufacturer'sspecified maximum speed limit. (Underno circumstances should you exceed31 mph (50 km/h).
• Avoid bumps, holes or sharp turns whendriving with snow chains.
• The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns as wellas locked wheel braking.
Checking tire inflation pressure
Correct tire inflation pressure helps improve driv- ing stability, save fuel and increase the servicelife of the tires.
WARNING
• Under-inflation is the most common cause of tire failure and may result insevere tire cracking, tread separation, or"blow-out," with unexpected loss of vehi-cle control and increased risk of injury.
• Under-inflated tires reduce the load car-rying capacity of your vehicle.
Cold tiresInflation pressure should be checked when the tires are cold. The tires are considered to be cold when they have the same temperature as the sur-rounding (ambient) air. This temperature is normally reached after the vehicle has been parked for at least 3 hours. After driving a distance of approximately 1 mile (1.6 km), the tires are considered to be hot. If youhave to drive farther than this distance to pumpyour tire(s), check and record the tire pressurefirst and add the appropriate air pressure whenyou get to the pump. When weather temperature changes occur, tire inflation pressures also change. A 10-degree

Removing a wheel
Wheel changes should always be carried out correctly.
1. Turn on the hazard warning flashers if the wheel change has to be done near passing traffic.
2. Apply the parking brake and put the gear selector in P.
CAUTION
Models with suspension and level con- trol *:
Turn this function off before raising the vehi- cle. To do so, go to
SettingsVehicleDisable Suspension & Leveling Control in
the center display's Top view.
WARNING
• The jack must correctly engage the jack attachment.
• Be sure the jack is on a firm, level, non-slippery surface.
• Never allow any part of your body to beextended under a vehicle supported by ajack.
• Use the jack intended for the vehicle whenchanging a tire. For any other job, usestands to support the vehicle.
• Apply the parking brake and put the gear selector in the Park (
P) position.
• Block the wheels standing on the ground, use rigid wooden blocks or large stones.
• The jack should be kept well-greased andclean, and should not be damaged.
• No objects should be placed between thebase of jack and the ground, or betweenthe jack and the attachment bar on thevehicle.
NOTE
The jack provided with your vehicle is intended to be used only in temporary situa-tions such as changing wheels in the event ofa flat tire. Only the jack that came with yourparticular model should be used to lift thevehicle. If the vehicle needs to be lifted morefrequently or for a prolonged period, using agarage jack or hoist is recommended. Alwaysfollow this device
