TEM (TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears in the dot
matrix liquid crystal display, one or more
of your tires is significantly under-inflated.
If the vehicle is being driven with low tire
pressure, the TPMS will activate 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 (25 km/h). For more details, see
“Warning/indicator lights and audible re-
minders” in the“2. Instruments and
controls” section and “Tire Pressure Mon-
itoring System (TPMS) ”in the “5. Starting
and driving” section.
WARNING
.If the low tire pressure warning light
illuminates or LOW PRESSURE informa-
tion 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. Driving with under-inflated
tires may permanently damage the tires
and increase the likelihood of tire fail-
ure. 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. If you have a flat tire,
replace it with a spare tire as soon as
possible.
. 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.
Contact your INFINITI retailer 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.
