one minute and then remain continuously illumi-
nated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunc-
tion exists. When the malfunction indicator is illu-
minated, the system may not be able to detect or
signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS to con-
tinue to function properly.
Messages in the instrument panelIf tire pressure is too low, the low tire pressure
warning symbol is shown in the instrument panel
along with a message.
• Tire pressure low Check tires, calibrate
after fill
• Tire pressure system Temporarily
unavailable
• Tire pressure system Service required
To keep in mind
•Always calibrate the system after changing
wheels or adjusting tire pressure. See the tire pressure placard on the driver's side B pillar
for Volvo-recommended tire pressures.
• If you switch to a tire of another size than the
factory-mounted tires, the system must be
calibrated for these tires to avoid false warn-
ings.
• If a spare wheel 7
is used, it is possible that
the tire pressure monitoring system will not
work correctly due to the differences
between the wheels.
• The system does not replace the need for
regular tire inspection and maintenance.
• It is not possible to deactivate the tire pres-
sure monitoring system.
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.

NOTE Always remember to calibrate the Tire Pres-
sure Monitoring System when the wheels
have been changed or the tire inflation pres-
sure has been corrected according to the tire
pressure decal or tire inflation pressure table.
If correct reference values have not been set,
the system cannot issue low tire pressure
alerts correctly.
The vehicle must be stationary with the
engine running to access the calibration but-
ton and to start the calibration process.
WARNING
The exhaust gases contain carbon monoxide,
which is invisible and odorless but very poi-
sonous. For this reason, always perform the
calibration procedure outdoors or in a work-
shop with exhaust gas evacuation equipment.

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).

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.

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.

Sealing compound bottleThe sealing compound bottle must be replaced if
its expiration date has passed (see the decal on
the bottle). Handle the old bottle as hazardous
waste.
The sealing compound bottle must be replaced
after use. Volvo recommends contacting an
