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 on the dot matrix liquid crystal
display.
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 automati-
cally 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 is
active as long as the low tire pressure
warning light remains illuminated.
For additional information, see
“Dot matrix
liquid crystal display” (P.2-20),“Tire Pres-
sure Monitoring System (TPMS)” (P.5-4)
and “Tire Pressure Monitoring System

Driving with under-inflated tires may
permanently damage the tires and in-
crease 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. 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 the 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.
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

Malfunction Indicator Light
(MIL)
If the malfunction indicator light comes on
steady or blinks while the engine is
running, it may indicate a potential emis-
sion control malfunction.
The malfunction indicator light may also
come on steady if the fuel-filler cap is loose
or missing, or if the vehicle runs out of fuel.
Check to make sure the fuel-filler cap is
installed and closed tightly, and that the
vehicle has at least 3 US gallons (14 liters)
of fuel in the fuel tank.
After a few driving trips, the
light should turn off if no other potential
emission control system malfunction ex-
ists.
If this indicator light remains on for 20
seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an
emission control system inspection/main-
tenance test. (See
“Readiness for Inspec-
tion/Maintenance (I/M) test (US only)” (P.9-
27).)
Operation:
The malfunction indicator light will come
on in one of two ways:
. Malfunction indicator light on steady —
An emission control system malfunc-
tion has been detected. Check the fuel-
filler cap. If the fuel-filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle. The
light should turn off after a few driving
trips. If thelight does not turn off
after a few driving trips, have the
vehicle inspected by an INFINITI retai-
ler. You do not need to have your
vehicle towed to the retailer.
. Malfunction indicator light blinking —
An engine misfire has been detected
