NOTE The jack provided with your vehicle is
intended to be used only in temporary situa-
tions 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.
WARNING •
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.
• Check that the jack is not damaged, the
threads are properly lubricated and it is
free from dirt.
• Be sure the jack is on a firm, level, non-
slippery surface and that it is upright and
not leaning.
• The jack must correctly engage in the
jack attachment.
• No objects should be placed between the
base of the jack and the ground, or
between the jack and the attachment bar
on the vehicle.
• Never let anyone remain in the vehicle
when it is raised on a jack.
• If a tire must be changed near passing
traffic, make sure all passengers move to
a safe location.
• Use a jack intended for the vehicle when
changing a tire. For any other job, use
stands to support the vehicle.
• Never crawl under or allow any part of
your body to be extended under a vehicle
supported by a jack.

1.

Clean the contact surfaces between the
wheel and the wheel hub.
2. Lift the wheel into place. Tighten the wheel bolts securely.
Do not grease the wheel bolt threads.
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.
NOTE
•
After inflating a tire, always replace the
valve cap to help prevent valve damage
caused by gravel, dirt, etc.
• Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove.

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.

Follow these instructions regarding handling the
spare wheel. The spare wheel is stored in a bag and should be
secured with two straps onto the floor of the
trunk/cargo compartment when the vehicle is
being driven
12
. The straps should be strapped
down crosswise over the wheel, attached to the
load anchoring eyelets and pulled taut.
Wheel changing tools are located under the
cargo compartment floor.

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.
12
The backrest in the third row of seats* must be folded down.

||WHEELS AND TIRES
572
CAUTION
Snow chains can be used on the vehicle, with
the following restrictions:
• Volvo recommends not using snow
chains on wheel dimensions larger than
19 inches.
• Always follow the manufacturer's installa-
tion instructions carefully. Install chains
as tightly as possible and retighten peri-
odically.
• Only put snow chains on the front wheels
(also applies to all-wheel drive vehicles).
• If accessory, aftermarket or "custom"
tires and wheels with different dimen-
sions than the original tires and wheels
are used, snow chains in some cases
may NOT be used. Sufficient distance
between the chains and brakes, suspen-
sion and body components must be
maintained.
• Check local regulations regarding the use
of snow chains before installing.
• Never exceed the snow chain manufac-
turer's specified maximum speed limit.
Under no circumstances should you
exceed 50 km/h (30 mph).
• Avoid bumps, holes or sharp turns when
driving with snow chains. •
Avoid driving on surfaces without snow as
this wears out both the snow chains and
the tires.
• The handling of the vehicle can be
adversely affected when driving with
chains. Avoid fast or sharp turns as well
as locked wheel braking.
• Some types of strap-on chains affect
brake components and therefore must
NOT be used. Consult a Volvo retailer for more information
about snow chains.

Winter driving (p. 461) Tire sealing system
13
The temporary tire sealing system can be used
to seal a puncture in a tire or to check and
adjust the pressure in the tire.
Models equipped with a spare wheel 14
do not
have the tire sealing system.
The tire sealing system consists of a compressor
and a bottle containing sealing compound. The
sealing functions as a temporary repair.
NOTE The sealing compound effectively seals tires
with punctures in the tread but may not be
able to fully seal tires with punctures in the
sidewall. Do not use the tire sealing system
on tires with large tears, cracks or similar
damage.
NOTE
The compressor is intended for temporary tire
sealing and is approved by Volvo.
LocationThe tire sealing system is located in a foam block
under the floor of the cargo compartment.

WARNING
Please keep the following points in mind
when using the tire sealing system:
• The sealing compound bottle (no. 8 in the
illustration) contains 1) rubber latex, natu-
ral and 2) ethanediol. These substances
are harmful if swallowed.
• The contents of this bottle may cause
allergic skin reactions or otherwise be
potentially harmful to the respiratory tract,
the skin, the central nervous system, and
the eyes.
Precautions:
• Keep out of reach of children.
• Do not ingest the contents.
• Avoid prolonged or repeated contact with
the skin. Remove any clothing that has
come into contact with sealant.

First aid:
• Skin: Wash affected areas of the skin
with soap and water. Get medical atten-
tion if symptoms occur.
• Eyes: Flush with plenty of water for least
15 minutes, occasionally lifting the upper
and lower eyelids. Get medical attention if
symptoms occur. •
Inhalation: Move the exposed person to
fresh air. If irritation persists, get medical
attention.
• Ingestion: Do NOT induce vomiting
unless directed to do so by medical per-
sonnel. Get medical attention.
• Disposal: Dispose of this material and its
container at a hazardous or special waste
collection point.
WARNING •
Do not remove the bottle while the tire
sealing system is being used.
• Do not remove the hose while the tire
sealing system is being used.
1.

Turn on the vehicle's hazard warning flashers
if the tire sealing system is to be used in an
area with traffic.
If the puncture was caused by a nail or simi-
lar object, do not remove it. It will help seal
the hole.
2. Peel off the speed limit sticker from the side of the compressor. Affix the decal to a clearly
visible location on the windshield to remind
the driver not to exceed this speed limit. Do
not drive faster than 80 km/h (50 mph) while
using a tire that has been temporarily
repaired with the tire sealing system. 3.
Make sure the switch is in the 0 (Off) posi-
tion and take out the electric cable and the
hose.
4. Unscrew the orange cover on the compres- sor and unscrew the cap on the sealing com-
pound bottle.
5. Screw the bottle onto the bottle holder as far as possible.
The bottle and the bottle holder are equip-
ped with catches to help prevent the sealing
compound from leaking. Once the bottle is
screwed into place into the bottle holder, it
cannot be unscrewed. The bottle can only be
removed by a workshop. Volvo recommends
an authorized Volvo workshop.
WARNING Do not unscrew the bottle. It is equipped with
a catch to prevent leakage.
6.

Unscrew the tire's valve cap and screw the
hose's valve connector as far as possible
onto the valve.
Be sure the air release valve on the com-
pressor's hose is completely closed.
