The arrows shows the direction of rotation of the
tireSummer and winter tires•
When switching between summer and
winter tires, mark the tires to indicate
where they were mounted on the car, e.g.,
LF = left front, RR = right rear
•
Tires with tread designed to roll in only one
direction are marked with an arrow on the
sidewall.
•
Incorrectly mounted tires impair the car's
braking properties and ability to force
aside rain, snow and slush.
•
The tires with the most tread should always
be at the rear (to reduce the risk of skid-
ding).
•
Contact a Volvo workshop if you are
unsure about the tread depth.
Tire rotationYour vehicle has no recommended tire rota-
tion. The following information is intended to
help you understand why.Tread setAs a tire ages and the rubber cures, front and
rear tires set at different angles. Therefore, if
tires are rotated, the tread will eventually set at
an angle that is a compromise. Even if ride,
handling, and road noise may still seem
acceptable, they may not be optimal. Further,
tires that are rotated, but not on a regular basis,
may actually cause more tire noise, faster tire
wear, and unpleasant changes in steering feel
and vehicle handling.
A tire that can fully adapt to its position will
provide better steering feel, lower tire noise,
and better fuel economy.Braking stability performanceYour vehicle is driven mainly by the front tires,
which will wear faster. This can be beneficial.
Having more tread on the rear tires will help
reduce oversteer. Oversteer is when a vehicle
wants to keep turning because of momentum
and dynamic forces on its suspension.Suspension wear diagnosticsEvery suspension needs periodic inspection
and maintenance. A tire's wear pattern can bean aid in detecting a suspension problem. Each
tire, if left in place, tells a story about the sus-
pension. Tire rotation, on the other hand, could
make suspension wear harder to detect. Early
detection is very important, because suspen-
sion problems can make tire wear worse.
If you do rotate your tires…Please follow the tire manufacturer's recom-
mendations, as outlined in the tire manufactur-
ers tire warranty pamphlet.
Your Volvo retailer can also provide guidance
based on your particular driving circumstan-
ces.

Tire Pressure Monitoring System (TPMS)
07``197 Introduction
The tire pressure monitoring system uses sen-
sors mounted in the tire valves to check infla-
tion pressure levels. When the vehicle is
moving at a speed of approximately 20 mph
(30 km/h) or faster, these sensors transmit
inflation pressure data to a receiver located in
the vehicle.
NOTE
USA – FCC ID: KR5S122780002
This device complies with part 15 of the
FCC rules. Operation is subject to the fol-
lowing conditions: (1) This device may not
cause harmful interference, and (2) this
device must accept any interference
received, including interference that may
cause undesired operation.When low inflation pressure is detected, TPMS
will light up the tire pressure warning light (also
referred to as a telltale) in the instrument panel,
and will display a message in the text window.
The wording of this message is determined by
the degree of inflation pressure loss.
NOTE
If a fault occurs in TPMS, the tire pressure
warning light will flash for approximately
1 minute and
TIRE PRESS SYST
SERVICE REQUIRED
will be displayed.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal-
function indicator is illuminated, 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 alternate tires
and wheels allow the TPMS to continue to
function properly.

program outlined in the Warranty and Service
Records Information booklet. This mainte-
nance program contains inspections and serv-
ices necessary for the proper function of your
vehicle. The maintenance services contain
several checks that require special tools and
training, and therefore must be performed by a
qualified technician. To keep your Volvo in top
condition, specify time-tested and proven

manufacturers to furnish written instructions to
the ultimate purchaser to assure the proper
servicing and function of the components that
control emissions. These services, which are
listed in the "Warranty and Service Records
Information" booklet, are not covered by the
warranty. You will be required to pay for labor
and material used.
MaintenanceYour Volvo passed several major inspections
before it was delivered to you, in accordance
with Volvo specifications. The maintenance
procedures outlined in the Warranty and Serv-
ice Records Information booklet, many of
which will positively affect your vehicle's emis-
sions, should be performed as indicated. It is
recommended that receipts for vehicle emis-
sion maintenance be retained in case ques-
tions arise concerning maintenance. Inspec-
tion and maintenance should also be
performed anytime a malfunction is observed
or suspected.Applicable warranties – U.S/CanadaIn accordance with applicable U.S. and Cana-
dian regulations, the following list of warranties
is provided.•

Owner maintenancePeriodic maintenance requirements and inter-
vals are described in your vehicle's Warranty
and Service Records Information booklet.
The following points can be carried out
between the normally scheduled maintenance
services.Each time the car is refueled:•
Check the engine oil level.
•
Clean the windshield, windshield wipers,
headlights, and taillights.
Monthly:•
Check cold tire pressure in all tires. Inspect
the tires for wear.
•
Check that engine coolant and other fluid
levels are between the indicated "min" and
"max" markings.
•
Clean interior glass surfaces with a glass
cleaner and soft paper towels.
•
Wipe driver information displays with a soft
cloth.
•
Visually inspect battery terminals for cor-
rosion. Corrosion may indicate a loose ter-
minal connector, or a battery near the end
of its useful service life. Consult a trained
and qualified Volvo service technician for
additional information.
As needed:•
Wash the car, including the undercarriage,
to reduce wear that can be caused by a
buildup of dirt, and corrosion that can be
caused by salt residues.
•
Clean leaves and twigs from air intake
vents at the base of the windshield, and
from other places where they may collect.NOTE
Complete service information for qualified
technicians is available online for purchase
or subscription at www.volvotechinfo.com.Emission inspection readinessWhat is an Onboard Diagnostic System
(OBD II)?OBD II is part of your vehicle's computerized
engine management system. It stores diagnos-
tic information about your vehicle's emission
controls. It can light the Check Engine light
(MIL) if it detects an emission control "fault." A
"fault" is a component or system that is not
performing within an expected range. A fault
may be permanent or temporary. OBD II will
store a message about any fault.
How Do States Use OBD II for Emission
Inspections?Many states connect a computer directly to a
vehicle's OBD II system. The inspector can
then read "faults." In some states, this type of
inspection has replaced the tailpipe emission
test.How Can My Vehicle Fail OBD II Emission
Inspection?Your vehicle can fail OBD II emission inspec-
tion for any of the following reasons.•
If your Check Engine (MIL) light is lit, your
vehicle may fail inspection.
•
If your vehicle's Check Engine light was lit,
but went out without any action on your
part, OBD II will still have a recorded fault.
Your vehicle may pass or fail, depending
on the inspection practices in your area.
•
If you had recent service that required dis-
connecting the battery, OBD II diagnostic
information may be incomplete and "not
ready" for inspection. A vehicle that is not
ready may fail inspection.
How Can I Prepare for My Next OBD II
Emission Inspection?•
If your Check Engine (MIL) light is lit – or
was lit but went out without service, have

your vehicle diagnosed and, if necessary,
serviced by a qualified Volvo technician.
•
If you recently had service for a lit Check
Engine light, or if you had service that
required disconnecting the battery, a
period of driving is necessary to bring the
OBD II system to "ready" for inspection. A
half-hour trip of mixed stop-and-go/high-
way driving is typically needed to allow
OBD II to reach readiness. Your Volvo
retailer can provide you with more infor-
mation on planning a trip.
•
Maintain your vehicle in accordance with
your vehicle's maintenance schedule.
