the emission control system and could result in
loss of emission warranty coverage. State and
local vehicle inspection programs will make
detection of misfueling easier, possibly resulting
in emission test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an
octane enhancing additive called methyl-
cyclopentadienyl manganese tricarbonyl
(MMT). If such fuels are used, your Emission
Control System performance may be affected,
and the Check Engine Light (malfunction
indicator light) located on your instrument
panel may light. If this occurs, please return
your vehicle to a trained and qualified Volvo
service technician for service.
Gasoline containing alcohol and ethers,
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing
"oxygenates" which are usually alcohols or
ethers. In some areas, state or local laws require
that the service pump be marked indicating use
of alcohols or ethers. However, there are areas in
which the pumps are unmarked. If you are not
sure whether there is alcohol or ethers in the
gasoline you buy, check with the service station
operator. To meet seasonal air quality standards,
some areas require the use of "oxygenated" fuel.
Volvo permits the use of the following "oxygen-
ated" fuels. However, the specified octane ratings
must still be met.
Alcohol - Ethanol
Fuels containing up to 10% ethanol by volume
may be used. Ethanol may also be referred to as
Ethyl alcohol, or "Gasohol".
Ethers - MTBE/ETBE: Fuels containing up to
15% MTBE/ETBE may be used.
MethanolDo not use gasolines containing methanol
(methyl alcohol, wood alcohol). This practice can
result in vehicle performance deterioration and
can damage critical parts in the fuel system. Such
damage may not be covered under the New
Vehicle Limited Warranty.

WARNING •
The wheel and tire sizes for your Volvo
are specified to meet stringent stability
and handling requirements. Unapproved
wheel/tire size combinations can nega-
tively affect your vehicle's stability and
handling.
• Any damage caused by installation of
unapproved wheel/tire size combinations
will not be covered by your new vehicle
warranty. Volvo assumes no responsibility
for death, injury, or expenses that may
result from such installations.

• Loading recommendations (p. 586) Tire direction of rotation
Tires with tread designed to roll in only one
direction are marked with an arrow on the side-
wall. The arrow shows the tire's direction of rotation.
• The tire should maintain the same direction
of rotation throughout its service life.
• Tires should only be moved between the
front and back, never from right to left or vice
versa.
• Incorrectly mounted tires impair the vehicle's
braking properties and ability to force aside
rain, snow and slush.
• The tires with the most tread should always
be mounted on the rear wheels to help
reduce the risk of skidding.
NOTE Use tires of the same type, dimensions and
make (manufacturer) on each axle.

560 function, the telltale will flash for approximately
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.

(p. 563)

• Vehicle status (p. 602) Action when warned of low tire
pressure
When the tire pressure monitoring system, Tyre
Pressure Monitoring System (TPMS), detects
low pressure in one or more of the vehicle's
tires, the driver will be alerted that action is nee-
ded. If the system's indicator symbol illumi-
nates and the message Tire pressure
low is displayed, check the tire pres-
sure and inflate if necessary. 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 pressure (see the tire pressure decal on the driver's side
door pillar).
4. Through calibration of the system via the center display after the tire pressure has
been adjusted.
Please be aware that the indicator symbol
will not go out until the low tire pressure has
been corrected and the system has been
recalibrated.
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 tempera-
ture 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. 9
An authorized Volvo workshop is recommended.

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.
