Deactivating suspension and leveling control
In certain situations, this function has to be turned off, for example when lifting the vehicle ona jack to help avoid problems created by the dif-ference in levels in the pneumatic suspensionwhen the vehicle is raised. 1.Tap
Settings in the center display's Top
view.
2. Tap
My CarSuspension .
3. Select
Disable Leveling Control.
Loading mode
Use 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 its ground 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.

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY REQUIRE-MENTS IN ADDITION TO THESE GRADES .
Quality grades can be found, where applica- ble, on the tire sidewall between the treadshoulder and maximum section width. Forexample: Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating based on the wear rate of the tire when testedunder controlled conditions on a specified gov-ernment test course. For example, a tire graded150 would wear one and one half (1 ½) times aswell on the government course as a tire graded100. The relative performance of tires dependsupon the actual conditions of their use, however,and many depart significantly from the norm dueto variation in driving habits, maintenance practi-ces and differences in road characteristics andclimate.
TRACTIONThe traction grades, from highest to lowest, areAA, A, B, and C, as measured under controlledconditions on specified government test surfacesof asphalt and concrete. A tire marked C mayhave poor traction performance. The tractiongrade assigned to this tire is based on braking (straight-ahead) traction tests and is not a meas-ure of cornering (turning) traction.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.
TEMPERATUREThe temperature grades are A (the highest), B, and C, representing the tire's resistance to thegeneration of heat and its ability to dissipate heatwhen tested under controlled conditions on aspecified indoor laboratory test wheel. Sustainedhigh temperature can cause the material of thetire to degenerate and reduce tire life, and exces-sive temperature can lead to sudden tire failure.The grade C corresponds to a minimum level ofperformance that all passenger vehicle tires mustmeet under the Federal Motor Safety StandardNo. 109. Grades B and A represent higher levelsof performance on the laboratory test wheel thanthe minimum required by law.
WARNING
The temperature grade for this tire is estab- lished for a tire that is properly inflated andnot overloaded. Excessive speed, under-infla-tion, or excessive loading, either separately orin combination, can cause heat buildup andtire failure.
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 frontwheels 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 snowchain information.

Wheel bolts
The wheel bolts hold the wheel in place.
CAUTION
Wheel bolts should be tightened to 103 ft. lbs. (140 Nm). Over-tightening could damagethe threads.
Only use wheels/rims that have been tested and approved by Volvo and are included in Volvo'sproduct range. Use a torque wrench to check that the wheel bolts are tightened correctly. Never lubricate the wheel bolts' threads.
Locking wheel bolts *A tool for removing locking wheel bolts can be found in the foam block under the cargo com-partment floor.

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 Leveling Control in the center dis-
play'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.

For vehicles equipped with leveling control *, if it is
also equipped with the optional pneumatic sus- pension, this must be deactivated before thevehicle is hoisted. This is done from the centerdisplay: 1. Tap
Settings in Top view.
2. Tap

CAUTION
When using an automatic car wash in which the vehicle has to be able to roll freely, theauto-hold brake function must be deactivated.If this is not done, the brakes will automati-cally be applied when the vehicle is stationary. To deactivate this function:
1. Drive the vehicle into the car wash
2. Turn off the auto-hold function using the
control on the center console
3. Turn off the parking brake's automatic function in the center display's Top view (tap
Settings, tap My CarParking
Brake and Suspension and deselectAuto Activate Parking Brake)
4. Put the gear selector in N
5. Switch off the ignition by turning the start knob to STOP and holding it in this posi-
tion for at least 4 seconds
The vehicle will then be able to roll freely.
CAUTION
• Before driving into an automatic car wash, turn off the optional rain sensor toavoid damaging the windshield wipers.
• Make sure that side view mirrors, auxiliarylamps, etc, are secure, and that anyantenna(s) are retracted or removed. Oth-erwise there is risk of the machine dis-lodging them.
• Chromed wheels:
Clean chrome-plated
wheels using the same detergents usedfor the body of the vehicle. Aggressivewheel-cleaning agents can permanentlystain chrome-plated wheels.
WARNING
• When the vehicle is driven immediately after being washed, apply the brakes,including the parking brake, several timesin order to remove any moisture from thebrake linings.
• Engine cleaning agents should not beused when the engine is warm. This con-stitutes a fire risk.
Exterior componentsVolvo recommends the use of special cleaningproducts, available at your Volvo retailer, forcleaning colored plastic, rubber, or ornamental components such as chromed strips on the exte-rior of your vehicle. The instructions for usingthese products should be followed carefully. Sol-vents or stain removers should not be used. The frames around the side windows, roof rails and door frames near the windows
* are made of
anodized aluminum and should only be washed with a cleaning product with a pH value between3.5 till 11.5.
