When the low tire pressure warning light illumi-
nates, you should stop and adjust the tire pres-
sure 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 recom-
mended 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.
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.
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 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.

mation display warnings appear.
