tem* (p. 561)
• Action when warned of low tire pressure
(p. 563)
• Tire pressure monitoring system* (p. 559)
• 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.

MAINTENANCE AND SERVICE
598Volvo's service program
To keep the vehicle as safe and reliable as pos-
sible, follow the Volvo service schedule speci-
fied in the Warranty and Maintenance Records
Information booklet.
Volvo recommends having an authorized Volvo
workshop perform service and maintenance.
Volvo workshops have the staff, service literature
and special tools to guarantee the highest quality
of service.
CAUTION To ensure the Volvo warranty is not invalida-
ted, check and follow the Service and War-
ranty Booklet.
Service and repairsService the vehicle regularly. Follow Volvo's rec-
ommended service intervals.
Detailed inspection and repairs may only be per-
formed by an authorized workshop.
WARNING
Do not make any repairs on this vehicle your-
self. Electrical cables and/or components that
have come loose may only be corrected by an
authorized workshop – an authorized Volvo
workshop is recommended.
IntroductionThe maintenance services contain several checks
that require special instruments and tools and
therefore must be performed by a qualified tech-
nician. To keep your Volvo in top condition, spec-
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.
Applicable warranties - U.S./Canada
In accordance with applicable U.S. and Canadian
regulations, the following list of warranties is pro-
vided.
• New Vehicle Limited Warranty
• Parts and Accessories Limited Warranty
• Corrosion Protection Limited Warranty
• Seat Belt and Supplemental Restraint Sys-
tems Limited Warranty
• Emission Design and Defect Warranty
• Emission Performance Warranty
These are federal warranties. Other warranties
are provided as required by state/provincial law.
Refer to your separate Warranty and Service
Records Information booklet for detailed informa-
tion concerning each of the warranties.

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
600
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 technician
can connect your vehicle to the workshop's Wi-Fi
network to perform troubleshooting and down-
load software. For this type of communication,
the vehicle only connects to the workshop's net-
work. The vehicle can only be connected to the
designated workshop networks, not to any other
network, e.g. your home network.
Manual connection to workshop Wi-FiManual connection is usually performed by a
service technician. Because the technician uses
the buttons on your remote key to connect the
vehicle, it is important that you bring a key with
buttons when taking the vehicle in to a workshop.
Pressing the lock button on the remote key three
times will connect the vehicle to the workshop's
Wi-Fi network.
When the car is connected to a Wi-Fi network,
the symbol appears in the center display.
