WARNING California Proposition 65
Operating, servicing and maintaining a pas-
senger vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to the
State of California to cause cancer and birth
defects or other reproductive harm. To mini-
mize exposure, avoid breathing exhaust, do
not idle the engine except as necessary, serv-
ice your vehicle in a well ventilated area and
wear gloves or wash your hands frequently
when servicing your vehicle. For more infor-
mation go to www.P65Warnings.ca.gov/

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.

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.

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.

Engine oil
For the recommended service intervals and war-
ranties to be applied, an approved engine oil
must be used. Volvo recommends: If the engine oil is not checked regularly and the
level becomes low, this could cause serious
engine damage.
CAUTION
To satisfy the requirements for the engine's
service intervals, all engines are factory-filled
with a specially adapted synthetic engine oil.
Great care has been put into the choice of oil,
with consideration given to service life, starta-
bility, fuel consumption and environmental
impact.
For the recommended service intervals to
apply, an approved engine oil must be used.
Only use the prescribed oil grade to top off or
change the oil. Otherwise, there is a risk of
the vehicle's service life, startability, fuel con-
sumption and environmental impact being
affected.
Failure to use engine oil of the prescribed
grade and viscosity could cause damage to
engine-related components. Volvo Car Corpo-
ration disclaims warranty liability for such type
of damage.
Volvo recommends entrusting oil changes to
an authorized Volvo workshop.
Volvo uses different systems to warn if the oil
level is too low/high or the oil pressure is low. On
engine variants with an oil pressure sensor, awarning symbol is displayed in the instrument
panel when oil pressure is low . On engine
variants with an oil level sensor, the warn-
ing symbol in the instrument panel and display
messages are used to alert the driver. Some
engine variants have both systems. Contact a
Volvo retailer for more information.
Change the engine oil and oil filter according to
the schedule specified in the Warranty and Main-
tenance Records Information booklet. Oils of a
higher grade than that specified may be used. If
the vehicle is driven in adverse conditions, Volvo
recommends using an oil with a higher grade
than that specified.
