Checking tire pressure
Correct inflation pressure helps improve driving
stability, save fuel and increase the service life of
the tires.
Tire pressure decreases over time, which is nor-
mal. Tire pressure also varies depending on the
ambient temperature. Driving on under-inflated
tires could cause the vehicle to overheat and lead
to damage. Tire pressure affects traveling com-
fort, road noise and driving characteristics.
Check the pressure in the tires every month. Use
the recommended inflation pressure for cold tires
for optimal tire performance and wear. Under-
inflated or over-inflated tires could cause uneven
tread wear.
Use an air pressure gauge and check the infla-
tion pressure on all the tires, including the spare
tire 4
, at least once a month and before long trips.
Volvo strongly recommends buying a reliable air
pressure gauge, as the automatic gauges provi-
ded at service stations may be inaccurate.
WARNING
Under-inflation is the most common
cause of tire failure and may result in
severe tire cracking, tread separation, or
"blow-out," with unexpected loss of vehi-
cle control and increased risk of injury.
Under-inflated tires reduce the load car-
rying capacity of your vehicle.
Cold tiresInflation pressure should be checked when the
tires are cold.
The tires are considered to be cold when they
have the same temperature as the surrounding
(ambient) air.
This temperature is normally reached after the
vehicle has been parked for at least 3 hours.
After driving for approximately 1.6 km (1 mile),
the tires are considered to be warm. If you need
to drive longer than that to inflate the tires, check
and record the inflation pressure of the tires first
and inflate accordingly when you arrive at the
pump.
When the ambient temperature changes, so does
the inflation pressure. A 10-degree temperature
drop causes a corresponding drop in inflation
pressure of 1 psi (7 kPa). Check the inflation
pressure of the tires regularly and adjust to the correct pressure, which can be found on the vehi-
cle's tire information placard or certification label.
If you check inflation pressure when the tires are
warm, you should never release air. The tires
become warm after driving and it is normal for
warm tires to have an inflation pressure above
the recommended pressure for cold tires. A warm
tire with an inflation pressure equal to or under
the recommended pressure for cold tires could
be significantly under-inflated.Related information

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 8
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.

detects low inflation pressure in a tire,
immediate action is required.
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 inflation pres- sure; see the tire pressure placard on the
driver's side B pillar for recommended pres-
sures for factory-mounted tires.
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. 11

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).

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.

ify time-tested and proven Genuine Volvo Parts
and Accessories.
The Federal Clean Air Act - U.S.
The Federal Clean Air Act requires vehicle manu-
facturers to furnish written instructions to the ulti-
mate 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.
Maintenance
Your Volvo passed several major inspections
before it was delivered to you, in accordance with
Volvo specifications. The maintenance proce-
dures outlined in the Warranty and Service
Records Information booklet, many of which will
positively affect your vehicle's emissions, should
be performed as indicated. It is recommended
that receipts for vehicle emission maintenance be
retained in case questions arise concerning
maintenance. Inspection and maintenance should
also be performed anytime a malfunction is
observed or suspected.

Periodic maintenance helps minimize
emissions
NOTE
Refer to your Service and Warranty Book-
let for a comprehensive service and main-
tenance schedule up to 240,000 km
(150,000 miles). This program contains
inspections and services necessary for
the proper function of your vehicle and
includes components that affect vehicle
emissions.
The Warranty and Service Records Infor-
mation booklet also contains detailed
information concerning the warranties
that apply to your vehicle.
On-board Diagnostic SystemOBD II is part of your vehicle's computerized
engine management system. It stores diagnostic
information about your vehicle's emission con-
trols. 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 perma-
nent or temporary. OBD II will store a message
about any fault.
Emission inspection readiness
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 inspec-
tion has replaced the tailpipe emission test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspection
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. Two half-
hour trips of mixed stop-and-go/highway
driving are typically needed to allow OBD II to
reach readiness. Your Volvo retailer can pro-
vide you with more information on planning a
trip.
Maintain your vehicle in accordance with your
vehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and intervals
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.

||MAINTENANCE AND SERVICE
612
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 corro-
sion. Corrosion may indicate a loose terminal
connector, or a battery near the end of its
useful service life. Consult your Volvo retailer
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 res-
idues.
Clean leaves and twigs from air intake vents at
the base of the windshield, and from other places
where they may collect.

workshop over Wi-Fi
Volvo workshops have a designated Wi-Fi net-
work for secure data transfer between your vehi-
cle and the workshop. Your visit to the workshop
will be easier and more effective when diagnos-
tics information and software can be transferred
over the workshop's network.
When you arrive at the workshop, your service
technician can connect your vehicle to the work-
shop's Wi-Fi network to perform troubleshooting
and download software. For this type of commu-
nication, the vehicle only connects to a work-
shop's network. It is not possible to connect the
vehicle to another Wi-Fi network (e.g. your home
network) in the same way as to a workshop's net-
work.
Connecting with remote keyConnection is usually managed by the service
technician, who will use the remote key buttons. It
is therefore important to bring a key with buttons
with you when you visit the workshop. Pressing
the lock button on the remote key three times will
connect the vehicle to the workshop's Wi-Fi net-
work.
When the car is connected to a Wi-Fi network,
the symbol appears in the center display.
