the tire pressure of all tires except the spare.
The low tire pressure warning light warns of
low tire pressure or indicates that the TPMS
is not functioning properly.
After the ignition switch is pushed ON, this
light illuminates for about 1 second and
turns off.
Low tire pressure warning:
If the vehicle is being driven with low tire
pressure, the warning light will illuminate. A
CHECK TIRE PRESSURE warning also
appears in the vehicle information display.
If you select the tire pressure information in
the center display, the Low Pressure infor-
mation will be displayed. The tire pressure
for each tire will also be displayed.
When the low tire pressure warning light
illuminates, you should stop and adjust the
tire pressure to the recommended COLD tire
pressure shown on the Tire and Loading
Information label. The low tire pressure
warning light does not automatically turn
off when the tire pressure is adjusted. After
the tire is inflated to the recommended
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 pressure gauge to
check the tire pressure.
The CHECK TIRE PRESSURE warning ap-
pears each time the ignition switch is placedin the ON position as long as the low tire
pressure warning light remains illuminated.
For additional information, see “Vehicle
information display” (P.2-21), “Tire Pressure
Monitoring System (TPMS)” (P.5-5) and
“Tire Pressure Monitoring System (TPMS) ”
(P.6-3).
TPMS malfunction:
If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is pushed ON. The light will remain on
after 1 minute. Have the system checked. It
is recommended you visit an INFINITI re-
tailer for this service. The CHECK TIRE
PRESSURE warning does not appear if the
low tire pressure warning light illuminates to
indicate a TPMS malfunction.
For additional information, see “Tire Pres-
sure Monitoring System (TPMS)” (P.5-5).
WARNING
.
If the light does not illuminate with
the ignition switch pushed ON, have
the vehicle checked as soon as possi-
ble. It is recommended you visit an
INFINITI retailer for this service.
. If the light illuminates or Low Pres-
sure information is displayed on the monitor screen 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. Driv-
ing 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 accident and
could result 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 to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving
after adjusting the tire pressure, a
tire may be flat or the TPMS may be
malfunctioning. If you have a flat tire,
replace it with a spare tire as soon as
possible. If no tire is flat and all tires
are properly inflated, it is recom-
mended you consult an INFINITI
retailer.
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, 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. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.
. Replacing tires with those not origin-
ally 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 four wheels correctly.
