CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap (if equipped). This
will prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.
Inflation pressures specified on the placard are always
“cold tire inflation pressure.” Cold tire inflation pressure
is defined as the tire pressure after the vehicle has not
been driven for at least three hours, or driven less than 1
mi (1 km) after a three hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire sidewall. Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12°F (7°C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the winter.
Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F (0°C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.

Tire Pressures for High Speed Operation
The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maximum
load is dangerous. The added strain on your tires could
cause them to fail. You could have a serious accident.
Don’t drive a vehicle loaded to the maximum capacity
at continuous speeds above 75 mph (120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial ply tires in sets of four (or six, in case
of trucks with dual rear wheels). Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs.

Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. (Refer to the paragraph on
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” placard for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability.WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of un-
approved tires and wheels may change suspension
dimensions and performance characteristics, resulting
in changes to steering, handling, and braking of your
vehicle. This can cause unpredictable handling and
stress to steering and suspension components. You
could lose control and have an accident resulting in
serious injury or death. Use only the tire and wheel
sizes with load ratings approved for your vehicle.
•Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have an accident.
•Failure to equip your vehicle with tires having ad-
equate speed capability can result in sudden tire fail-
ure and loss of vehicle control.

TIRE PRESSURE MONITOR SYSTEM (TPMS)
•
The Tire Pressure Monitor System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
•The tire pressure will vary with temperature by about
1 psi (6.9 kPa) for every 12°F (6.5°C). This means that
when the outside temperature decreases, the tire pres-
sure will decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven
for at least three hours, or driven less than 1 mi (1 km)
after a three hour period. The cold tire inflation
pressure must not exceed the maximum inflation
pressure molded into the tire sidewall. Refer to “Tires
– General Information” in this section for information
on how to properly inflate the vehicle’s tires. The tire pressure will also increase as the vehicle is driven - this
is normal and there should be no adjustment for this
increased pressure.
•The TPMS will warn the driver of a low tire pressure
if the tire pressure falls below the low-pressure warn-
ing limit for any reason, including low temperature
effects and natural pressure loss through the tire.
•The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not
turn off until the tire pressure is at or above the
recommended cold placard pressure. Once the low tire
pressure warning (Tire Pressure Monitoring [TPM]
Telltale Light) illuminates, you must increase the tire
pressure to the recommended cold placard pressure in
order for the TPM Telltale Light to turn off. The system
will automatically update and the TPM Telltale Light
will turn off once the system receives the updated tire

pressures. The vehicle may need to be driven for up to
10 minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.
For example, your vehicle may have a recom-
mended cold (parked for more than three hours)
placard pressure of 30 psi (207 kPa). If the ambient
temperature is 68°F (20°C) and the measured tire
pressure is 27 psi (186 kPa), a temperature drop to
20°F (-7°C) will decrease the tire pressure to ap-
proximately 26 psi (179 kPa). This tire pressure is
sufficiently low enough to turn ON the TPM Telltale
Light. Driving the vehicle may cause the tire pres-
sure to rise to approximately 27 psi (186 kPa), but
the TPM Telltale Light will still be ON. In this
situation, the TPM Telltale Light will turn OFF only
after the tires are inflated to the vehicle’s recom-
mended cold placard pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the TPM sensor.

NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance or to provide warning of a tire failure
or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•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.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the TPM Telltale Light.
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Premium System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors mounted to each
wheel as part of the valve stem transmit tire pressure
readings to the receiver module.
NOTE: It is particularly important for you to check the
tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
•Receiver module,
•Four TPM sensors,
266 STARTING AND OPERATING

Should this occur, you should stop as soon as possible
and inflate the tires with low pressure (those flashing in
the EVIC graphic) to the vehicle’s recommended cold
placard pressure value. Once the system receives the
updated tire pressures, the system will automatically
update, the graphic display in the EVIC will stop flash-
ing, and the TPM Telltale Light will turn off. The vehicle
may need to be driven for up to 10 minutes above 15 mph
(25 km/h) in order for the TPMS to receive this informa-
tion.
Check TPMS Warning
If a system fault is detected, the TPM Telltale Light will
flash on and off for 75 seconds and then remain on solid.
The system fault will also sound a chime. In addition, the
EVIC will display aCHECK TPM SYSTEM message for three seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received.

WARNING!
•Do not attempt to repair a tire on the side of the vehicle close to
traffic. Pull far enough off the road to avoid the danger of being hit
when operating the jack or repairing a tire.
•Cuts or punctures larger than approximately 0.16 in (4 mm), tire
damage caused by driving with extremely low tire pressure or on
a flat tire, or a damaged wheel can pose a hazard while driving.
TIREFIT should not be used in such circumstances. Do not drive
the vehicle under such circumstances. Contact your nearest autho-
rized dealer for assistance.
•Take care not to allow the contents of TIREFIT to come in contact
with hair, eyes or clothing. TIREFIT is harmful if inhaled, swal-
lowed, or absorbed through the skin: It causes skin, eye, and
respiratory irritation. Any contact with eyes or skin should be
flushed immediately with plenty of water. If clothing comes in
contact with TIREFIT, change clothing as soon as possible.
•In case of allergic reaction or rash, consult a physician immedi-
ately. Keep TIREFIT out of reach of children. If swallowed, rinse
mouth immediately with plenty of water and drink plenty of
water. Do not induce vomiting! Consult a physician immediately.
•Keep away from open flame or heat source.

9. Press the switch 3 on the air pump to I (ON). The air
pump should start to inflate the tire and the tire sealant
(white fluid) will flow from the sealant bottle 5 through
the TIREFIT sealant hose 6 and into the tire.
10. Allow the air pump to run for five minutes and then
read the pressure gauge 4. If the tire inflates to 26 psi (1.8
bar) or greater, proceed to Step 19 of this procedure. If
not, proceed to the following step.
11. Press the AIR PUMP switch 3 to 0 (OFF). Then,
disconnect the TIREFIT system from the tire and place it
back in the vehicle.
12. Release the parking brake and drive the vehicle back
and forth approximately 30 ft (9.1 m) to distribute the
sealant more evenly within the tire.
13. Turn on the hazard warning flashers.
14. Move the shift lever to the PARK position, turn OFF
the engine, and set the parking brake.15. Disconnect the air pump hose 1 from the underside
of the sealant bottle 5 by flipping the hose valve open.
16. Connect the air pump hose valve to the tire valve and
flip the hose valve closed.
17. Leave the parking brake set and the shift lever in
PARK and start the engine.
18. Press the switch 3 on the air pump to I (ON). The air
pump should inflate the tire to at least 26 psi (1.8 bar)
within five minutes. If the tire inflates to this level,
proceed to the following step.
NOTE:If a tire pressure of
26 psi (1.8 bar) is not obtained within five minutes, the
tire is too badly damaged. Do not attempt to drive the
vehicle further. Call for assistance.
19. With a tire pressure of no less than 26 psi (1.8 bar)
press the AIR PUMP switch 3 to 0 (OFF) and turn off the
engine. Then, disconnect the TIREFIT system from the
tire and place it back in the vehicle.
