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
situations 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 fre-
quently or for a prolonged period, using
a garage jack or hoist is recommended.
Always follow this device's instructions
for use.

Removing a wheel

Read through all instructions before starting.
Before raising the vehicle using a jack or lift,
take out all the tools you will need.

1. Turn on the vehicle's hazard warning

flashers if a wheel change must be per-
formed in an area with traffic.

2. Make sure that the parking brake is

engaged and put the gear selector in

position.

3. Place chocks in front of and behind the

wheels that are still on the ground. For
example, use heavy wooden blocks or
large stones.

4. Using the lug wrench, screw the towing

eye into place as far as possible.

5. Remove the plastic covers from the wheel

bolts using the designated tool.

6. With the vehicle still on the ground, use

the lug wrench/towing eye to loosen the
wheel bolts ½-1 turn by pressing down-
ward (counterclockwise). Always start

Spare wheel

The spare wheel is a Temporary Spare and
can be used to temporarily replace a punc-
tured tire on one of the vehicle's regular
wheels.

The spare wheel is only intended for tempo-
rary use. Replace it with a normal wheel as
soon as possible.

The driving characteristics of the vehicle
change and ground clearance reduces when
the spare wheel is used. Do not wash the vehi-
cle in an automatic car wash while using the
Temporary Spare.

The recommended tire pressure must be
maintained regardless of at which position the
temporary spare wheel is used on the vehicle.

If the spare wheel is damaged, a replacement
can be purchased from a Volvo retailer.

WARNING

Current legislation prohibits the use of the

"Temporary Spare" wheel other than as a

temporary replacement for a punctured

tire. It must be replaced as soon as possi-

ble by a standard tire. Roadholding and

handling may be affected with the "Tempo-

rary Spare" wheel in use.

WARNING

•

Never drive faster than 80 km/h
(50 mph) with a spare tire mounted on
the vehicle.

•

The vehicle must never be driven with
more than one "Temporary Spare"
wheel mounted.

•

Driving with a spare wheel may alter
the driving characteristics of the vehi-
cle. Replace the spare wheel with a
normal wheel as soon as possible.

•

The spare wheel is smaller than the
normal wheel, which affects the vehi-
cle's ground clearance. Watch for high
curbs and do not wash the vehicle in
an automatic car wash when a spare
wheel is mounted.

•

Follow the manufacturer's recom-
mended 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.

Not available on all models.

Stowing a flat tire

1. Screw the spare tire's retaining bolt back

on.

Folding up the cargo compartment floor
(p. 540)

Do not attempt to unscrew the lower part
of the retaining bolt if it is attached to the
body, as this could cause it to break.

If the retaining bolt becomes dislodged
from its lower attachment point in the
body under the spare tire, replace it in the
hole and turn clockwise to secure it again.

WARNING

On vehicles with 48 V batteries, the bolt is

attached to the battery box instead of the

body. If the lower part of the retaining bolt

is not dislodged when the spare tire is

taken out, it should be removed to help

prevent injury when the flat tire is replaced.

2. Put the tools back in their correct posi-

tions in the foam block.

3. Then lower the trunk/cargo compartment

floor and place the punctured tire in the
trunk/cargo compartment.

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 snow
tires, the correct type of tires must be moun-
ted on all four wheels.

Tips for changing snow tires

When switching between regular tires and
snow tires, mark the tires according to which
side they were mounted on, e.g.

for left and

for right.

Contact a Volvo retailer for assistance deter-
mining the most suitable rims and tires.

Studded tires

Studded tires should be broken in by driving
500–1000 km (300–600 miles) slowly and
gently to help the studs settle properly in the
tires. This gives the tire, and especially the
studs, a longer service life.

Legal requirements concerning the use of
studded tires may vary. Always follow local
laws and regulations.

Tread depth

Road conditions with ice, slush and low tem-
peratures place considerably higher demands

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 than
18 inches

WARNING

Use Volvo genuine snow chains or equiva-

lent snow chains that are suitable for the

vehicle 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 Volvo

workshop. Use of the wrong snow chains

could cause serious damage to the vehicle

and result in an accident.

Snow chains can be used on the vehicle,
with the following restrictions:

•

Always follow the manufacturer's
installation instructions carefully. Install
chains as tightly as possible and
retighten periodically.

•

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, sus-
pension and body components must
be maintained.

•

Check local regulations regarding the
use of snow chains before installing.

•

Never exceed the snow chain manu-
facturer'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.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

WHEELS AND 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.

the tire sealing system is being used.

Preparations

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
similar 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.

Also peel off the warning decal and affix it
securely to the side of the wheel.

3. Make sure the switch is in the

(Off)

position and take out the electric cable
and the hose.

4. Attach the sealing compound bottle to the

compressor, making sure that the red
arrows on the compressor and bottle are
aligned, and then turn clockwise until it
clicks into place.

The bottle is equipped with a check valve
that prevents fluid leakage when the bot-
tle is not connected to the compressor.

5. Attach the hose in the bottle opening and

turn clockwise until it clicks into place.

6. Unscrew the tire's valve cap and screw

the hose's valve connector as far as possi-
ble onto the valve.

Begin tire sealing procedure

Connect the electrical cable to the nearest
12 V outlet and start the vehicle.

Make sure that none of the vehicle's other
12 V sockets are used while the compres-
sor is running.

WARNING

Never leave children unattended in the

vehicle while the engine is running.

WARNING

Inhaling exhaust fumes could lead to seri-

ous injury. Never leave the engine running

in an enclosed space or a space without

sufficient ventilation.

8. Start the compressor by moving the

switch to the

(On) position.

When the compressor starts, the pressure
can increase up to 6 bar (88 psi), but the
pressure will decrease after
approx. 30 seconds.

WARNING

Never stand next to a tire being inflated

with the compressor. If cracks, bulges, etc.

form on the tire, switch off the compressor

immediately. The vehicle should not be

driven. Call roadside assistance to have the

vehicle towed to a workshop for inspec-

tion/replacement of the tire. Volvo recom-

mends an authorized workshop.

9. Inflate the tire for 7 minutes.

To help avoid overheating, the compressor
should never be used for more than
10 minutes at a time.

10. Switch off the compressor and check the

inflation pressure using the air pressure
gauge. The inflation pressure should be
between 1.8 bar (22 psi) and 2.5 bar
(36 psi). If the inflation pressure is too
high, use the air release valve to release
air.

The sealing compound bottle must be
removed in order to access the air release
valve. Remove the bottle in the following
order:

1. Remove the hose from the tire's valve.
2. Remove the hose from the bottle.
3. Remove the bottle from the compres-

sor.

4. Reconnect the hose directly to the

compressor.

5. Screw the hose back on to the tire's

valve.

6. Release air using the air release valve.

WARNING

If pressure falls below 1.8 bar (22 psi), the

hole in the tire may be too large. The vehi-

cle should not be driven. Call roadside

assistance to have the vehicle towed to a

workshop for inspection/replacement of

the tire. Volvo recommends an authorized

workshop.

11. Switch off the compressor and remove

the electrical cable.

12. Unscrew the hose from the tire's valve and

screw the valve cap back on.

•

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.

13. Clean the hose before stowing it and

make sure that no sealing compound is
leaking out.

14. Immediately drive the vehicle at least

3 km (2 miles) at a maximum speed of
80 km/h (50 mph) to allow the sealing
compound to seal the tire, and then
recheck the inflation pressure.

WARNING

During the tire's first revolution, some seal-

ing compound may spray out of the punc-

ture hole. Before driving away, make sure

that no one is near the vehicle who could

be sprayed with sealing compound. Make

sure no one is within 2 meters (7 feet) of

the vehicle.

15.

Rechecking the inflation pressure

Connect the hose to the tire's valve and
screw the hose connector onto the valve
as far as possible. The compressor must
be switched off.

16. Check the inflation pressure on the air

pressure gauge.

•

If the pressure is under 1.3 bar (19 psi),
the tire is not sufficiently sealed. The
vehicle should not be driven. Call road-
side assistance to have the vehicle
towed.

•

If the inflation pressure is higher than
1.3 bar (19 psi), the tire must be inflated
to the inflation pressure specified on
the tire pressure decal on the driver's
side door pillar (1 bar = 100 kPa =
14.5 psi). If the inflation pressure is too
high, use the air release valve to release
air.

WARNING

Check inflation pressure regularly.

Volvo recommends driving to the nearest
authorized Volvo workshop to have the tire
replaced/repaired. Inform the workshop that
the tire contains sealing compound.

The sealing compound bottle and the hose
must be replaced after use. Volvo recom-
mends contacting an authorized Volvo work-
shop for replacement.
