Introduction
Location of the tire sealing system
Certain models are equipped with a tire sealing
system* that enables you to temporarily seal a
hole in the tread surface and re-inflate a flat tire,
or to adjust a tire’s inflation pressure.
The system consists of an air compressor, a
container for the sealing compound, wiring to
connect the system to the vehicle’s electrical
system via one of the 12-volt sockets, and a
hose used to connect the system to the tire’s
inflation valve.
The 12-volt socket is located in the front tunnel
console.
Accessing the tire sealing systemThe tire sealing system is stowed in the com-
partment in the rear side of the ski hatch in the
center of the rear seat backrest. See page
119 for information on opening this hatch.
1. Lift the floor hatch in the trunk.
2. Lift out the tire sealing system.
NOTE
•The tire sealing system is only intended
to seal holes on the tire’s tread area, not
the sidewall.
•Tires with large holes or tears cannot be
repaired with the tire sealing system.
•After use, stow the tire sealing system
properly to help prevent rattling.
WARNING
•After using the tire sealing system, the
vehicle should not be driven farther than
approximately 120 miles (200 km).
•Have the tire inspected by a trained and
qualified Volvo service technician as
soon as possible to determine if it can
be permanently repaired or must be
replaced.
•The vehicle should not be driven faster
than 50 mph (80 km/h) while using a tire
that has been temporarily repaired with
the tire sealing system.
•After using the tire sealing system, drive
carefully and avoid abrupt steering
maneuvers and sudden stops.

•Eyes: Flush with plenty of water for least
15 minutes, occasionally lifting the
upper and lower eyelids. Get medical
attention if symptoms occur.
•Inhalation: Move the person to fresh air.
If irritation persists, get medical atten-
tion.
Tire sealing system–temporarily
repairing a flat tire
G019723
Temporarily repairing a flat tire is done in two
stages:
•Stage 1: The hole is sealed by pumping
sealing compound into the tire. The car is
then driven a short distance to distribute
the sealing compound in the tire.

196* Option/accessory, for more information, see Introduction.
NOTE
Do not remove any foreign objects (nails,
etc.) from the tire before using the sealing
system.
•Stage 2: The tire’s inflation pressure is
checked and adjusted if necessary.
WARNING
•Never leave the tire sealing system
unattended when it is operating.
•Keep the tire sealing system away from
children.
•Be sure the vehicle is parked safely off
the road and away from moving traffic.
•Apply the parking brake.
Stage 1: Sealing the hole1. Open the cover on the tire sealing kit.
2. Peel off the speed limit sticker and affix it
to the steering wheel hub where it will be
clearly visible to the driver.
3. Ensure that the on/off switch is in posi-
tion 0 (the 0 side of the switch should be
pressed down).4. Put on the gloves included in the tire seal-
ing system.
WARNING
Contact with the sealing compound may
cause skin irritation. If contact occurs, wash
the affected area immediately with soap and
water.
5. Unscrew the orange cover over the bottle
holder and unscrew the cap on the bottle
of sealing compound.
NOTE
Do not break the seal on the bottle. This
occurs automatically when the bottle is
screwed into the holder.
6. Screw the bottle into the bottle holder.
WARNING
The bottle is equipped with a catch to keep
it securely in place and help prevent sealing
compound leakage. Once in place, the bot-
tle cannot be unscrewed. This must be done
by a trained and qualified Volvo service
technician.
7. Remove the valve cap from the tire’s infla-
tion valve and screw the tire sealing sys-
tem’s hose connector onto the valve as
tightly as possible by hand.
8. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
9. Start the vehicle’s engine.
10. 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 approxi-
mately 88 psi (6 bar) while the sealing com-
pound is being pumped into the tire. The
pressure should return to a normal level
after approximately 30 seconds.
11. Within seven minutes, inflate the tire to
between 22—44 psi (1.8—3.0 bar). Switch
off the compressor briefly to get a clear
reading from the pressure gauge. The
compressor should not be used for more
than 10 minutes at a time to avoid over-
heating.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
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.
12. Switch off the compressor and disconnect
the electrical wire from the 12-volt socket.
13. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
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.
CAUTION
If your vehicle is equipped with the Tire
Pressure Monitoring System (TPMS), the
use of the sealing compound may lead to
incorrect tire pressure readings or in rare
cases, damage to the tire pressure sensor.
Use the tire sealing system to check and
adjust the damaged 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 pres-
sure.
•The empty bottle of sealing compound
cannot be removed from the bottle
holder. Consult a trained and qualified
Volvo service technician to have the
bottle removed and properly disposed
of.
WARNING
If heavy vibrations, unsteady steering
behavior, or noises should occur while driv-
ing, reduce speed and park the vehicle in a
safe place. Recheck the tire for bumps,
cracks, or other visible damage, and
recheck its inflation pressure. 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.
Stage 2: Checking inflation pressure1. Connect the tire sealing system as descri-
bed in stage 1.
2. Refer to the inflation pressure tables for the
correct inflation pressure. If the tire needs
to be inflated, start the tire sealing system’s
compressor. If necessary, release air from
the tire by turning the air release knob
counterclockwise.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If you interrupt your trip for more than 1
hour, check the inflation pressure in the
damaged tire again before continuing.

Replacing the sealing compound
container
The sealing compound container must be
replaced if:
•the tire sealing system has been used to
repair a tire
•the container’s expiration date has passed
(see the date on decal).
NOTE
•After use, the sealing compound bottle,
the hose, and certain other system
components must be replaced. Please
consult your Volvo retailer for replace-
ment parts.
•If the sealing compound bottle’s expi-
ration date has passed, please take it to
a Volvo retailer or a recycling station
that can properly dispose of harmful
substances.
Inflating tires
The tire sealing system can be used to inflate
the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.
Ensure that the on/off switch is in posi-
tion 0 (the 0 side of the switch should be
pressed down).
3. Take out the electrical wire and hose.
4. Remove the valve cap from the tire’s infla-
tion valve and screw the hose connector
onto the valve as tightly as possible by
hand.
5. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
6. Start the vehicle’s engine.
WARNING
•The vehicle’s engine should be running
when the tire sealing system is used to
avoid battery drain. Therefore, be sure
the vehicle is parked in a well ventilated
place, or outdoors, before using the sys-
tem.
•Children should never be left unattended
in the vehicle when the engine is running.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to
get a clear reading from the pressure
gauge.
8. Refer to the tire inflation tables for the cor-
rect inflation pressure. If the tire needs to
be inflated, start the tire sealing system’s
compressor (press the on/off switch to
position I). If necessary, release air from the
tire by turning the air release knob coun-
terclockwise.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
9. Turn off the compressor (press the on/off
switch to position 0) when the correct infla-
tion pressure has been reached.
10. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
11. Disconnect the electrical wire from the
12-volt socket.

7. Raise the vehicle until the wheel to be
changed is off the ground.
8. Unscrew the wheel nuts completely and
carefully remove the wheel so as not to
damage the threads on the wheel bolts.
WARNING
•The jack must correctly engage the jack
attachment.
•Be sure the jack is on a firm, level, non-
slippery surface.
•Never allow any part of your body to be
extended under a car supported by a
jack.
•Use the jack intended for the car when
changing a tire. For any other job, use
stands to support the car.
•Apply the parking brake and put the gear
selector in the Park (P) position.
•Block the wheels standing on the ground,
use rigid wooden blocks or large stones.
•The jack should be kept well-greased
and clean, and should not be damaged.
•No objects should be placed between
the base of jack and the ground, or
between the jack and the attachment bar
on the vehicle.

07 Wheels and tires
Tire Pressure Monitoring System (TPMS)
07

201 Introduction
The tire pressure monitoring system1 uses sen-
sors mounted in the tire valves to check infla-
tion pressure levels. When the vehicle is mov-
ing 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 one of the following mes-
sages in the text window:
LOW TIRE PRESS.
CHECK TIRES or VERY LOW TIRE
PRESSURE.
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.
1This system is standard on U.S. models and optional on Canadian models

NOTE
•TPMS indicates low tire pressure but
does not replace normal tire mainte-
nance. For information on correct tire
pressure, please refer to the tables
beginning on page 181, or consult your
Volvo retailer.
•The tire pressure warning light will not
identify which tire is underinflated. Be
sure to check all four tires.
•A certain amount of air seepage from
the tires occurs naturally and tire pres-
sure fluctuates with seasonal changes
in temperature. Always check tire pres-
sure regularly.
Erasing warning messagesWhen a low tire pressure warning message has
been displayed, and the tire pressure warning
light has come on:
1. Use a tire pressure gauge to check the
inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure
(consult the tire pressure placard or the
tables, see page 181 ).
3. In certain cases, it may be necessary to
drive the vehicle for several minutes at a
speed of 20 mph (30 km/h) or faster. Thiswill erase the warning text and the warning
light will go out.
WARNING
Incorrect inflation pressure could lead to tire
failure, resulting in a loss of control of the
vehicle.
Changing wheels with TPMSPlease note the following when changing or
replacing the factory installed TPMS wheels/
tires on the vehicle:
•Only the factory-mounted wheels are
equipped with TPMS sensors in the valves.
•If the vehicle is equipped with a temporary
spare tire, this tire does not have a TPMS
sensor.
•If wheels without TPMS sensors are moun-
ted on the vehicle, TIRE PRESS SYST
SERVICE REQUIRED will be displayed
each time the vehicle is driven above
25 mph (40 km/h) for 10 minutes or more.
•Once TPMS sensors are properly installed,
the warning message should not reappear.
If the message is still displayed, drive the
vehicle for several minutes at a speed of
20 mph (30 km/h) or faster to erase the
message.
•Volvo recommends that TPMS sensors be
fitted on all wheels used on the vehicle.Volvo does not recommend moving sen-
sors back and forth between sets of
wheels.
NOTE
•If you change to tires with a different
recommended inflation pressure, the
TPMS system must be recalibrated to
these tires. This must be done by an
authorized Volvo retailer or workshop.
•If a tire is changed, or if the TPMS sen-
sor is moved to another wheel, the sen-
sor's seal, nut, and valve core should be
replaced.
•When installing TPMS sensors, the
vehicle must be parked for at least
15 minutes with the ignition off. If the
vehicle is driven within 15 minutes, a
TPMS error message will be displayed.
CAUTION
When inflating tires with TPMS valves, press
the pump's mouthpiece straight onto the
valve to help avoid bending or otherwise
damaging the valve.
Recalibrating TPMS (Canadian models
only)
In certain cases, it may be necessary to reca-
librate TPMS to conform to Volvo's recom-
