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
