Jack*
The jack can be used to lift the vehicle to e.g.
change a wheel. The illustration is generic – the design may vary.
CAUTION •
When not in use, the jack* should be kept
in its storage compartment under the
cargo compartment floor.
• The jack provided with your vehicle is
intended to be used only in temporary sit-
uations such as changing wheels in the
event of a flat tire. Only the jack that
came with your particular model should
be used to lift the vehicle. If the vehicle
needs to be lifted more frequently or for a
prolonged period, using a garage jack or
hoist is recommended. Always follow this
device's instructions for use. The jack needs to be cranked together to the
correct position in order to fit.
Models with leveling control*
If the vehicle is equipped with the optional pneu-
matic suspension, it must be turned off before
the vehicle is lifted on a jack.

in contact with the vehicle's jack attachment
point. Make sure the top of the jack (or the
garage lift arms) is correctly positioned in the
attachment point, with the bump on the top
of the jack in the recess in the attachment
point and the base positioned vertically under
the attachment point.
11. Turn the jack so that the crank is as far as possible from the side of the vehicle, which
will position the jack's arms perpendicular to
the vehicle's direction of movement.
12. Raise the vehicle until the wheel to be changed can move freely. Unscrew the wheel
bolts and lift off the wheel.

3. Lower the vehicle so that the wheel cannot rotate.
4. Tighten the wheel bolts in a crisscross pat- tern (as shown in illustration). It is important
that the wheel bolts are securely tightened.
Tighten to a torque of 140 Nm (103 ft.lbs.).
Use a torque wrench to check torque. 5. Press the plastic covers onto the wheel bolts.
WARNING The wheel bolts may need to be tightened
again several days after a wheel change.
Temperature fluctuations and vibrations can
cause them to loosen slightly.

11
The spare wheel is a Temporary spare and can
be used to temporarily replace a punctured tire
on one of the vehicle's regular wheels. The spare tire is only intended for temporary use.
Replace it with a normal wheel as soon as possi-
ble.
The driving characteristics of the vehicle change
and ground clearance reduces when the spare
wheel is used. Do not wash the vehicle in an
automatic car wash while using the Temporary
Spare.
The recommended tire pressure must be main-
tained regardless of at which position the tempo-
rary spare wheel is used on the vehicle.
If the spare wheel is damaged, a new one can be
purchased from a Volvo retailer.
WARNING Current legislation prohibits the use of the
"Temporary Spare" tire other than as a tem-
porary replacement for a punctured tire. It
must be replaced as soon as possible by a
standard tire. Road holding and handling may
be affected with the "Temporary Spare" in
use. Do not drive faster than 80 km/h
(50 mph).

WARNING •
The vehicle must never be driven with
more than one "Temporary spare" tire
mounted.
• Driving with a spare wheel may alter the
driving characteristics of the vehicle.
Replace the spare wheel with a normal
wheel as soon as possible.
• The spare wheel is smaller than the nor-
mal wheel, which affects the vehicle's
ground clearance. Watch for high curbs
and do not wash the vehicle in an auto-
matic car wash when a spare wheel is
mounted.
• Follow the manufacturer's recommended
tire inflation pressure for the spare wheel.
• On all-wheel drive vehicles, the drive on
the rear axle can be disconnected.
• If the spare wheel is mounted on the
front axle, snow chains must not be used.
• The spare wheel must not be repaired.
CAUTION The vehicle must not be driven with wheels of
different dimensions or with a spare tire other
than the one that came with the vehicle. The
use of different size wheels can seriously
damage your vehicle's transmission.

Snow tires
Snow tires are designed for winter driving.
Volvo recommends snow tires with specific
dimensions. The tire dimensions vary depending
on engine type. When driving with snow tires, the
correct type of tires must be mounted 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 which side they
were mounted on, e.g. L for left and R for right.
Studded tiresStudded tires should be broken in by driving
500–1000 km (300–600 miles) slowly and gen-
tly to help the studs settle properly in the tires.
This gives the tire, and especially the studs, 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 tempera-
tures place considerably higher demands on tires
than summer conditions. Volvo therefore recom-
mends not driving on snow tires that have a tread
depth of less than 4 mm (0.15 inch).

Using snow chains and/or snow tires can help
improve traction in winter driving conditions.
WARNING Use Volvo genuine snow chains or equivalent
snow chains that are suitable for the vehicle
model and the tire and wheel sizes. Only one-
sided snow chains are permitted.
If uncertain about snow chains, Volvo recom-
mends contacting an authorized Volvo work-
shop. Use of the wrong snow chains could
cause serious damage to the vehicle and
result in an accident.
