6. Be sure the air release valve on the com-

pressor's hose is completely closed. Remove
the valve cap from the tire’s inflation valve
and screw the tire sealing system’s hose
connector onto the valve as tightly as possi-
ble by hand.

7. Connect the electrical wire to the nearest

12-volt socket in the vehicle.

NOTE

Be sure that none of the other 12-volt sock-
ets is being used while the compressor is in
operation.

8. Start the tire sealing system’s compressor by

pressing the on/off switch to position I.

WARNING

•

Never stand next to the tire being inflated
when the compressor is in operation.

•

If cracks, bubbles, etc. form on the tire,
switch off the compressor immediately.

•

If there is visible damage to the sidewall or
the rim, the tire cannot be repaired. The
vehicle should not be driven if this occurs.
Contact a towing service or Volvo On Call
Roadside Assistance if applicable.

NOTE

The air pressure gauge will temporarily show
an increase in pressure to approximately
88 psi (6 bar) while the sealing compound is
being pumped into the tire. The pressure
should return to a normal level after approxi-
mately 30 seconds.

9. Pump the tire for 7 minutes.

CAUTION

The compressor should not be used for more
than 10 minutes at a time to avoid overheat-
ing.

10. Switch off the compressor and check the

inflation pressure on the air pressure gauge.
Inflation pressure should be between
22—51 psi (1.8—3.5 bar). Use the air
release valve to release some air from the
tire if necessary.

WARNING

If the pressure remains below 22 psi (1.8 bar)
after approximately seven minutes, turn off
the compressor. In this case, the hole is too
large to be sealed and the vehicle should not
be driven.

11. Switch off the compressor and disconnect

the electrical wire from the 12-volt socket.

12. Unscrew the hose from the tire's inflation

valve and put the cover on the hose back into
place to help prevent seepage of residual
sealing compound from the hose.

13. Reinstall the valve cap.

CAUTION

•

After inflating the tires, always reinstall the
valve cap to help avoid damage to the
valve from dirt, gravel, etc.

•

Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove.

14. Immediately drive the vehicle for approxi-

mately 2 miles (3 km) at a maximum speed
of 50 mph (80 km/h) to distribute the seal-
ing compound in the tire. During the tire's
first revolution, some sealing compound may
spray out of the puncture hole.

WARNING

No one should stand closer to the vehicle
than approx. 7 ft (2 m) when it drives away to
help avoid being sprayed with sealing com-
pound.

CAUTION

If your vehicle is equipped with the Tire Pres-
sure Monitoring System (TPMS), the use of
the sealing compound may lead to incorrect
tire pressure readings or in rare cases, dam-
age to the tire pressure sensor. Use the tire
sealing system to check and adjust the dam-
aged tire's inflation pressure.

NOTE

•

Safely stow the tire sealing system in a
convenient place as it will soon be used
again to check the tire’s inflation pressure.

•

The empty bottle of sealing compound
cannot be removed from the bottle holder.
Consult a trained and qualified Volvo serv-

ice technician to have the bottle removed
and properly disposed of.

WARNING

If heavy vibrations, unsteady steering behavior,
or noises should occur while driving, reduce
speed and park the vehicle in a safe place.
Recheck the tire for bumps, cracks, or other
visible damage, and recheck its inflation pres-
sure. If the pressure is below 19 psi (1.3 bar),
do not continue driving. Have the vehicle
towed to a trained and qualified Volvo service
technician.

15. Rechecking the pressure

Reconnect the tire sealing system's hose to
the tire's inflation valve.

16. Without starting the compressor, check the

inflation pressure on the air pressure gauge.

•

If the pressure is under 19 psi (1.3 bar),
the puncture has not been sealed suffi-
ciently and the vehicle should not be
driven. Have the vehicle towed to a trained
and qualified Volvo service technician.

•

If the pressure is more than 19 psi
(1.3 bar), connect the electrical wire to a
12-volt socket, start the compressor and
inflate the tire to the correct pressure
(see the tire pressure decal on the on the
driver's side B-pillar (the structural mem-
ber at the side of the vehicle, at the rear
of the driver's door opening). Use the air
release valve to release some air from the
tire if necessary.

17. Switch off the compressor and disconnect

the electrical wire from the 12-volt socket.
Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.

Do not attempt to remove the sealing com-
pound bottle from the tire sealing system. It
cannot be turned counterclockwise.

18. Fold the hose into the sealing system box

and return the components to the cargo
compartment.

MAINTENANCE AND SERVICING

504

Volvo's service program

Periodic maintenance and service performed at
the intervals specified in your Warranty and
Service Records Information booklet will help
keep your vehicle running well.

Introduction

The 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 the federal warranties; other warran-
ties 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 Warranty and Service
Records Information booklet for a com-
prehensive service and maintenance
schedule up to 150,000 miles (240,000
km). This program contains inspections
and services necessary for the proper
function of your vehicle and includes
components that affect vehicle emis-
sions.

•

The Warranty and Service Records Infor-
mation booklet also contains detailed
information concerning the warranties
that apply to your vehicle.

On-board Diagnostic System

OBD 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.

MAINTENANCE AND SERVICING

505

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 maintenance

Periodic 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.

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.

Automatically connecting to a
workshop

Without driver confirmation

This is the most convenient way to transmit trou-
ble-shooting data. The driver does not need to
confirm that the vehicle will establish a connec-
tion.

If the vehicle stops at a workshop and the engine
is switched off using the start knob, a message
will appear above the status bar in the center dis-
play. The vehicle will be automatically connected
when the driver's door is opened if the driver
does not tap the

Cancel

button in the message.

To help prevent the driver from being disturbed
by unwanted requests to connect (e.g., if the
vehicle is often parked near a workshop with an
authorized Volvo network), the vehicle will switch
to manual connection if the driver cancels a con-
nection request twice within 5 days.

With driver confirmation

With this alternative, the driver must confirm a
connection.

If the vehicle stops at a workshop and the engine
is switched off using the start knob, a pop-up
window will open in the center display. The vehi-
cle will be automatically connected when the driv-
er's door is opened if the driver taps

Start battery

The vehicle's electrical system is single pole and
uses the body and engine block as conductors.

The start (main) battery is used to power electri-
cal components and systems. However, the
hybrid battery is used to start the gasoline
engine.

The start battery should only be replaced by a
trained and qualified Volvo service technician.

The start battery is an Absorbed Glass Mat
(AGM) 12-volt battery that is dimensioned for
use in vehicles to support electrical systems and
functions.

The service life of a battery is affected by factors
such as driving conditions/style, the number of
starts, climate, etc. Extreme cold may also further
decrease the battery’s starting capacity.

•

Never disconnect the start battery while the
engine is running.

•

Check that the start battery is correctly con-
nected and that the clamps on its terminals
are properly tightened.

WARNING

•

Never expose the battery to open flame
or electric spark.

•

Do not smoke near the battery.

•

Battery fluid contains sulfuric acid. Do not
allow battery fluid to contact eyes, skin,
fabrics or painted surfaces. If contact
occurs, flush the affected area immedi-
ately with water. Obtain medical help
immediately if eyes are affected.

WARNING

PROPOSITION 65 WARNING!

Battery posts, terminals, and related accesso-
ries contain lead and lead compounds, chemi-
cals known to the state of California to cause
cancer and reproductive harm. Wash hands
after handling.

It is not possible to charge another vehicle's bat-
tery using the connection points in the engine
compartment. If the connection points are used
to charge another vehicle's battery it may cause a
fuse to blow, which means that the connection
points will not function.

If an external auxiliary battery is used to start the
vehicle, use the connection points in the engine
compartment. The start battery's terminals should
never be used. See the following illustration.

Positive connection point

Negative connection point

Only modern battery chargers should be used to
charge the start battery. Quick charge functions
should not be used and could damage the bat-
tery.

If both the start and hybrid batteries are fully dis-
charged, both will have to be charged. Only
charging the hybrid battery in this situation is not
possible. Before the hybrid battery can be
charged, the start battery must be charged to a
certain level.

CAUTION

•

The infotainment system's energy-saving
feature may not function correctly or at
all, and/or a message may be displayed if
a battery charger or jumper cables are
not connected properly.

•

The negative terminal on the battery must
never be used to connect a jumper cable
or a battery charger. Only the ground
point on the chassis may be used.

NOTE

•

The service life of the start battery is
shortened if it becomes discharged
repeatedly.

•

The service life of the start battery is
affected by factors such as driving condi-
tions and climate. Extreme cold may also
further decrease the battery's start
capacity.

•

Because the battery’s starting capacity
decreases with time, it may be necessary
to recharge it if the vehicle is not driven
for an extended period of time or if the
vehicle is usually only driven short dis-
tances.

•

Driving for at least 15 minutes a week or
connecting the battery to a charger with
automatic maintenance charging will help
keep it in good operating condition.

•

Keeping the start battery fully charged
will help maximize its service life.

The start battery is located in the cargo compartment

When replacing the start battery, a new bat-
tery with the same specifications and dimen-
sions must be used. The battery should only
be replaced by a trained and qualified Volvo
service technician.

Support battery

Vehicles equipped with Start/Stop are equipped
with two 12-volt batteries.

In addition to a heavy-duty start battery, models
with Start/Stop also have a support battery that
provides extra current during the Start/Stop
function's start sequence.

The following table shows the specifications for
the support battery:

•

When replacing the start battery or support
battery in a vehicle with Start/Stop, an
Absorbed Glass Mat (AGM) must be used.

•

The greater the current consumption in the
vehicle, the more the generator has to oper-
ate and the battery is charged. This increases
fuel consumption.

•

When the start battery's charge is below the
minimum permitted level, the Start/Stop
function will be disabled.

When the Start/Stop function is temporarily disa-
bled due to high current consumption:

•

The engine will auto-start, even if the brake
pedal is depressed.

The support battery does not normally required
more service than the start battery. If questions
arise, consult a Volvo retailer or trained and quali-
fied Volvo service technician.

CAUTION

When connecting an external start battery or
a battery charger, the Start/Stop function may
be temporarily disabled if the negative termi-
nal on the vehicle's start battery is used to
connect an external start battery or a battery
charger. Only the negative connection point
in the engine compartment may be used as a
ground point.

MAINTENANCE AND SERVICING

NOTE

If the start battery is completely discharged
and the vehicle has no normal electrical func-
tions, and the engine is then started using an
auxiliary battery or battery charger, the
Start/Stop function will be activated. The
engine can then be auto-stopped but may not
auto-start again due to an insufficient charge
level in the start battery.

To help ensure auto-start, the start battery
should be charged first. At a temperature of
approx. 60 °F (15 °C), the battery should be
charged for at least 1 hour, preferably using
an external battery charger. At lower tempera-
tures, the battery should be charged for
3–4 hours.

If a charger is not available, it is advisable to
disable the Start/Stop function until the bat-
tery is sufficiently recharged.

Hybrid battery

The vehicle's electric motor is powered by a
rechargeable, maintenance-free, lithium-ion
hybrid battery.

The vehicle cannot be started if the hybrid
battery is completely discharged.

WARNING

The vehicle's hybrid battery may only be serv-
iced or replaced by a trained and qualified
Volvo service technician.

Battery coolant

The hybrid battery's cooling system has its own
expansion tank.

Filling the hybrid battery's cooling system should
only be done by a trained and qualified Volvo
service technician.
