Action when warned of low tire

pressure

When the tire inflation pressure monitoring
system

11

 detects low inflation pressure in a

tire, immediate action is required.

If the system's indicator sym-
bol illuminates and the mes-
sage 

Tire pressure low

 is

displayed, check the tire
pressure and inflate if neces-
sary.

1. Switch off the ignition.

2. Check the inflation pressure on all four

tires using a tire pressure gauge.

3. Inflate the tire to the correct inflation pres-

sure; see the tire pressure placard on the
driver's side B pillar for recommended
pressures for factory-mounted tires.

4. After the inflation pressure has been

adjusted, always save the new inflation
pressure in the system via the center dis-
play.

Please be aware that the indicator symbol
will not go out until the low tire pressure
has been corrected and a storing proce-
dure has been started for the new inflation
pressure.

NOTE

To help prevent incorrect inflation pressure,
pressure should be checked when the tires
are cold. The tires are considered to be
cold when they have reached the same
temperature as the ambient temperature
(about 3 hours after the vehicle was last
driven). After driving for a few kilometers,
the tires will warm up and the pressure will
increase.

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.

WARNING

•

Incorrect inflation pressure could lead
to tire failure, which could cause the
driver to lose control of the vehicle.

•

The system cannot predict sudden tire
damage.

Spare wheel

14

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.

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. 

L

 for left and

R

 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.

NOTE

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

on tires than summer conditions. Volvo there-
fore recommends not driving on snow tires
that have a tread depth of less than 4 mm
(0.15 inch).

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
19 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.

WHEELS AND TIRES

}}

585

CAUTION

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.

•

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.

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 possi-
ble onto the valve.

Be sure the air release valve on the com-
pressor's hose is completely closed.

7.

Begin tire sealing procedure

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

NOTE

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.

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 

I

 (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.

CAUTION

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

20

An authorized Volvo workshop is recommended.

WHEELS AND TIRES

}}

589

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 3.5 bar
(51 psi). If the inflation pressure is too
high, use the air release valve to release
air.

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.

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.

13. Put the protective hose cover onto the

hose to help prevent leakage of any resid-
ual sealing compound. Return the equip-
ment to the cargo compartment.

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.

trailer, from the vehicle's Federal/Canadian
Motor Vehicle Safety Standards (FMVSS/
CMVSS) label, and the vehicle's tire informa-
tion placard:

Curb weight

The weight of the vehicle including a full tank
of fuel and all standard equipment. It does not
include passengers, cargo, or optional equip-
ment.

Capacity weight

All weight added to the curb weight, including
cargo and optional equipment. When towing,
towbar weight is also part of cargo weight.

Permissible axle weight

The maximum allowable weight that can be
carried by a single axle (front or rear). These
numbers are shown on the Federal/Canadian
Motor Vehicle Safety Standards (FMVSS/
CMVSS) label. The total load on each axle
must never exceed its maximum permissible
weight.

Gross vehicle weight (GVW)

The vehicle's curb weight + cargo + passen-
gers.

Steps for Determining Correct Load
Limit

1. Locate the statement "the combined

weight of occupants and cargo should
never exceed XXX kg or XXX lbs." on your
vehicle's placard.

2. Determine the combined weight of the

driver and passengers that will be riding in
your vehicle.

3. Subtract the combined weight of the

driver and passengers from XXX kg or XXX
lbs.

4. The resulting figure equals the available

amount of cargo and luggage load
capacity. For example, if the "XXX"
amount equals 1400 lbs. and there will be
five 150 lb. passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400 - 750 (5 ×
150) = 650 lbs.)

5. Determine the combined weight of lug-

gage and cargo being loaded on the vehi-
cle. That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.

6. If your vehicle will be towing a trailer, load

from your trailer will be transferred to your
vehicle. Consult this manual to determine
how this reduces the available cargo and
luggage load capacity of your vehicle.

WARNING

•

Exceeding the permissible axle weight,
gross vehicle weight, or any other
weight rating limits can cause tire over-
heating resulting in permanent defor-
mation or catastrophic failure.

•

Do not use replacement tires with
lower load carrying capacities than the
tires that were original equipment on
the vehicle because this will lower the
vehicle's GVW rating. Use only tires
with the correct load carrying capacity.
Consult your Volvo retailer for informa-
tion.
