SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light,
displayingin the instrument panel,
monitors the circuits for the air bag systems,
pretensioners and all related wiring.
When the ignition switch is in the ON
position, the supplemental air bag warning
light illuminates for about 7 seconds and
then turns off. This means the SRS air bag
systems are operational.
If any of the following conditions occur, the
air bag and/or pretensioner systems need
servicing:

.The supplemental air bag warning light
remains on after approximately 7 sec-
onds.
. The supplemental air bag warning light
flashes intermittently.
. The supplemental air bag warning light
does not come on at all.
Under these conditions, the air bag or
pretensioner systems may not operate prop-
erly. They must be checked and repaired. It is
recommended you visit an INFINITI retailer
for this service.
WARNING
If the supplemental air bag warning light
is on, it could mean that the front air
bag, side air bag, curtain air bag and/or
pretensioner systems will not operate in
an accident. To help avoid injury to
yourself or others, have your vehicle
checked as soon as possible. It is recom-
mended you visit an INFINITI retailer for
this service.
REPAIR AND REPLACEMENT
PROCEDURE
The front air bags, side air bags, curtain air
bags and pretensioners are designed to
activate on a one-time-only basis. As a
reminder, unless it is damaged, the supple-
mental air bag warning light will remain
illuminated after inflation has occurred.
These systems should be repaired and/or
replaced as soon as possible. It is recom-
mended you visit an INFINITI retailer for this
service.
When maintenance work is required on the
vehicle, the front air bags, side air bags,
curtain air bags, pretensioners and related
parts should be pointed out to the person
conducting the maintenance. The ignition
switch should always be in the LOCK
position when working under the hood or
inside the vehicle.
WARNING
. Once a front air bag, side air bag, or
curtain air bag has inflated, the air
bag module will not function again
and must be replaced. Additionally,
the activated pretensioner must also
be replaced. The air bag module and
pretensioner should be replaced. It is recommended you visit an INFINITI
retailer for this service. However, the
air bag module and pretensioner
system cannot be repaired.
. The front air bag, side air bag, curtain
air bag and the pretensioner system
should be inspected if there is any
damage to the front end or side
portion of the vehicle. It is recom-
mended you visit an INFINITI retailer
for this service.
. If you need to dispose of the supple-
mental air bag or pretensioner or
scrap the vehicle, it is recommended
you visit an INFINITI retailer. Correct
supplemental air bag and seat belt
pretensioner system disposal proce-
dures are set forth in the appropriate
INFINITI Service Manual. Incorrect
disposal procedures could cause per-
sonal injury.
. If there is an impact to your vehicle
from any direction, your Occupant
Classification Sensor (OCS) should be
checked by an INFINITI retailer to
verify it is still functioning correctly.
The OCS should be checked even if no
air bags deploy as a result of the
impact. Failure to verify proper OCS
function may result in an improper air
bag deployment resulting in injury or

you visit an INFINITI retailer for this service.
(See “Anti-lock Braking System (ABS) warn-
ing light” (P.2-10).)
WARNING
.
Your brake system may not be work-
ing properly if the warning light is on.
Driving could be dangerous. If you
judge it to be safe, drive carefully to
the nearest service station for re-
pairs. Otherwise, have your vehicle
towed because driving it could be
dangerous.
. Pressing the brake pedal with the
engine stopped and/or low brake
fluid level may increase your stopping
distance and braking will require
greater pedal effort as well as pedal
travel.
. If the brake fluid level is below the
minimum or MIN mark on the brake fluid reservoir, do not drive until the
brake system has been checked. It is
recommended you visit an INFINITI
retailer for this service.

2-12Instruments and controls
If the light illuminates when the FEB system
is ON, it may indicate that the system is
unavailable. See “Forward Emergency Brak-
ing (FEB)” (P.5-103) for more details.
Low fuel warning light
This light illuminates when the fuel in the
tank is getting low. Refuel as soon as it is
convenient, preferably before the fuel gauge
reaches the 0 (empty) position.
There will be a small reserve of fuel remain-
ing in the tank when the fuel gauge reaches
the 0 position.
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
tire (if so equipped).
The low tire pressure warning light warns of
low tire pressure and flat tire (if so equipped)
or indicates that the TPMS is not functioning
properly.
After the ignition switch is placed in the ON
position, 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.The “Tire Pressure Low - Add Air” warning
also appears in the vehicle information dis-
play.
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 automatically 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 “Tire Pressure Low - Add Air” warning is
active as long as the low tire pressure
warning light remains illuminated.
For additional information, see “Vehicle
information display” (P.2-18), “Tire Pressure
Monitoring System (TPMS)” (P.5-5) and
“Tire Pressure Monitoring System (TPMS)”
(P.6-3).
Flat tire warning (if so equipped):
The flat tire warning warns of a flat tire.
If the vehicle is being driven with one or more
flat tires, the low tire pressure warning light
will illuminate continuously and a chime will
sound for 10 seconds. A “Flat Tire - Visit
dealer” warning also appears in the vehicle information display.
The chime will only sound at the first
indication of a flat tire and the warning light
will illuminate continuously. When the flat
tire warning is activated, have the system
reset and the tire checked, and replaced if
necessary. It is recommended you visit an
INFINITI retailer for these services. Even if
the tire is inflated to the specified COLD tire
pressure, the warning light will continue to
illuminate until the system is reset by an
INFINITI retailer.
Your vehicle can be driven for a limited time
on a flat tire. See “Run-flat tires” (P.6-4).
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 placed in the ON position. The light
will remain on after the 1 minute. Have the
system checked. It is recommended you visit
an INFINITI retailer 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
.Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment man-
ufacturer for the possible influences
before use.
. 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 (if
so equipped) as soon as possible. If no
tire is flat and all tires are properly
inflated, it is recommended you con-
sult an INFINITI retailer.
. For models with run-flat tires,
although you can continue driving
with a punctured run-flat tire, re-
member that vehicle handling stabi-
lity is reduced, which could lead to an
accident and personal injury. Also,
driving a long distance at high speeds
may damage the tires.
— Do not drive at speeds above 50 MPH (80 km/h) and do not drive
more than approximately 93 miles
(150 km) with a punctured run-
flat tire. The actual distance the
vehicle can be driven on a flat tire
depends on outside temperature,
vehicle load, road conditions and
other factors.
— If you detect any unusual sounds or vibrations while driving with a
punctured run-flat tire, pull off
the road to a safe location and
stop the vehicle as soon as possi-
ble. The tire may be seriously damaged and need to be replaced.
. 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 the 1 minute.
Have your tires replaced and/or
TPMS system reset as soon as pos-
sible. 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.
