Forward Emergency Braking
(FEB) system warning light
This light comes on when the ignition switch
is placed in the ON position. It turns off after
the engine is started.
This light illuminates when the Forward
Emergency Braking (FEB) with Pedestrian
Detection system is set to OFF in the vehicle
information display.
If the light illuminates when the FEB with
Pedestrian Detection system is ON, it may
indicate that the system is unavailable. See “Forward Emergency Braking (FEB) with
Pedestrian Detection system” (P.5-95) for
more details.
Low tire pressure warning light
Your vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that monitors
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
"Tire Pressure Low Add Air" warning also
appears in the vehicle information display.
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 may not automatically turn
off when the tire pressure is adjusted. After
the tire is inflated to the recommended
pressure, the vehicle must be driven atspeeds 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 "Tire Pressure Low Add Air" warning
appears each time the ignition switch is
placed in the ON position as long as the
low tire pressure warning light remains
illuminated.
For additional information, see “Vehicle
information display” (P.2-20), “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 "Tire Pressure Low
Add Air" 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 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 failure. Serious vehicle damage
could occur and may lead to an
accident and could result in serious
personal injury. Check the tire pres-
sure 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 pres-
sure, 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 recommended 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.
Malfunction Indicator Light
(MIL)
If the malfunction indicator light comes on
steady or blinks while the engine is running,
it may indicate a potential emission 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 exists.
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/maintenance test.
(See “Readiness for Inspection/Mainte-
nance (I/M) test” (P.10-34).)
Operation:
The malfunction indicator light will come on
in one of two ways:
. Malfunction indicator light on steady —
