When the low tire pressure warning light
illuminates, you should stop and adjust the
tire pressure of all 4 tires to the recom-
mended COLD tire pressure shown on the
Tire and Loading Information label located
in the driver’s door opening. The low tire
pressure warning light does not automati-
cally turn off when the tire pressure is ad-
justed. After the tire is inflated to the rec-
ommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h)
to activate the TPMS and turn off the low
tire pressure warning light. Use a tire pres-
sure gauge to check the tire pressure.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section and in the “In case of emergency”
section.
TPMS malfunction:
If the TPMS is not functioning properly, the low
tire pressure warning light will flash for approxi-
mately 1 minute when the ignition switch is
turned ON. The light will remain on after the 1
minute. Have the system checked by an INFINITI
dealer.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section and “Tire pressure” in the “Main-
tenance and do-it-yourself” section.WARNING
●If the light does not illuminate with the
ignition switch turned ON, have the ve-
hicle checked by an INFINITI dealer as
soon as possible.
● If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and in-
crease the likelihood of tire failure. Se-
rious vehicle damage could occur and
may lead to an accident and could re-
sult in serious personal injury. Check
the tire pressure for all four tires. Adjust
the tire pressure to the recommended
COLD tire pressure shown on the Tire
and Loading Information label located
in the driver’s door opening to turn the
low tire pressure warning light OFF. If
the light still comes on while driving
after adjusting the tire pressure, a tire
may be flat. If you have a flat tire, re-
place it with a spare tire as soon as
possible. ●
When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI dealer as soon as
possible for tire replacement and/or
system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
CAUTION
● The TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly.
● If the vehicle is being driven at speeds
of less than 16 MPH (25 km/h) , the
TPMS may not operate correctly.
● Be sure to install the specified size of
tires to the 4 wheels correctly.

WARNING
●If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an acci-
dent and could result in serious per-
sonal injury. Check the tire pressure for
all four tires. Adjust the tire pressure to
the recommended COLD tire pressure
shown on the Tire and Loading Informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a spare tire as soon as
possible. (See “Flat tire” in the “In case
of emergency” section for changing a
flat tire.) ●
When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI dealer as soon as
possible for tire replacement and/or
system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
● Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CAUTION
Do not place metalized film or any metal
parts (antenna, etc.) on the windows. This
may cause poor reception of the signals
from the tire pressure sensors, and the
TPMS will not function properly.
Some devices and transmitters may temporarily
interfere with the operation of the TPMS and
cause the low tire pressure warning light to illu-
minate. Some examples are:
– Facilities or electric devices using similar radio
frequencies are near the vehicle.
– If a transmitter set to similar frequencies is being used in or near the vehicle.
– If a computer (or similar equipment) or a DC/AC converter is being used in or near the
vehicle.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS) . It monitors tire pres-
sure of all tires except the spare. When the low
tire pressure warning light is lit, one or more of
your tires is significantly under-inflated. If
equipped, the system also displays pressure of
all tires (except the spare tire) on the display
screen by sending a signal from a sensor that is
installed in each wheel. If the vehicle is being
driven with low tire pressure, the TPMS will acti-
vate and warn you of it by the low tire pressure
warning light. This system will activate only when
the vehicle is driven at speeds above 16 MPH
(26 km/h) . For more details, refer to
“Warning/indicator lights and audible reminders”
in the “Instruments and controls” section, “Tire
pressure information” in the “Monitor, climate,
audio, phone and voice recognition systems”
section and “Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving” section.

CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Shift the transmission into P (Park) .
4. Turn off the engine.
5. Raise the hood to warn other traffic and to signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from traffic

The wheel nuts must be kept tight-
ened to specifications at all times. It
is recommended that wheel nuts be
tightened to specification at each
tire rotation interval.
WARNING
● After rotating the tires, check and
adjust the tire pressure.
● Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.) .
● Do not include the spare tire in
the tire rotation.

Tire wear and damage
WARNING
● Tires should be periodically in-
spected for wear, cracking, bulg-
ing or objects caught in the tread.
If excessive wear, cracks, bulging
or deep cuts are found, the tire(s)
should be replaced. ●
The original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
● Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician because
some tire damage may not be ob-
vious. Replace the tires as neces-
sary to prevent tire failure and
possible personal injury.
● Improper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact an INFINITI
dealer.
● For additional information re-
garding tires, refer to “Important
