WARNING
.After adjustment, release the adjust-
ment button and try to move the
shoulder belt anchor up and down to
make sure it is securely fixed in
position.
. The shoulder belt anchor height
should be adjusted to the position
best for you. Failure to do so may
reduce the effectiveness of the entire
restraint system and increase the
chance or severity of injury in an
accident.
SEAT BELT EXTENDERS
If, because of body size or driving position, it
is not possible to properly fit the lap-
shoulder belt and fasten it, an extender that
is compatible with the installed seat belts is
available that can be purchased. The ex-
tender adds approximately 8 in (200 mm) of
length and may be used for either the driver
or front passenger seating position. It is
recommended you visit an INFINITI retailer
for assistance with purchasing an extender if
an extender is required.
WARNING
.It is recommended that only INFINITI
seat belt extenders, made by the
same company which made the origi-
nal equipment seat belts, be used
with the INFINITI seat belts.
. Adults and children who can use the
standard seat belt should not use an
extender. Such unnecessary use could
result in serious personal injury in the
event of an accident.
. Never use seat belt extenders to
install child restraints. If the child
restraint is not secured properly, the
child could be seriously injured or
killed in a collision or a sudden stop.
SEAT BELT MAINTENANCE
.To clean the seat belt webbing, apply a
mild soap solution or any solution re-
commended for cleaning upholstery or
carpets. Then, wipe with a cloth and
allow the seat belts to dry in the shade.
Do not allow the seat belts to retract
until they are completely dry.
. If dirt builds up in the shoulder belt guide
of the seat belt anchors, the seat belts
may retract slowly. Wipe the shoulder belt guide with a clean, dry cloth.
. Periodically check to see that the seat
belt and the metal components such as
buckles, tongues, retractors, flexible
wires and anchors work properly. If loose
parts, deterioration, cuts or other da-
mage on the webbing is found, the entire
seat belt assembly should be replaced.

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 system is
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 and/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

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 —
An emission control system malfunction
has been detected. Check the fuel-filler

Flicker image (example)
. When LED headlights are viewed on the
Smart Rearview Mirror display, the
images may flicker. This is normal.
. Due to diffused reflection from external
environment, images on the screen may
flicker. This is not a malfunction.
. A quick movement of a thing may not be
able to display on the camera view
screen. This is not a malfunction.
. Turn on the headlights at twilight or in a
tunnel, etc.
. The Smart Rearview Mirror mode (cam-
era view mode) display is different from
the conventional rearview mirror. Ob-
jects in the display may differ from actual distance. Do not solely rely on
the Smart Rearview Mirror. Always rely
on your own operation to avoid acci-
dents.
. If the brightness of the camera view
display is adjusted to excessive bright
level, it may cause an eyestrain in the
driving. Adjust the brightness properly.
. Use the rear window wiper when it rains.
If the camera view image is still unclear
when the rear window wiper is in
operation, check the deterioration of
the rear window wiper blade.
. When using the rear window wiper,
images on the screen may flicker. This
is not a malfunction.
. Defog the rear window with defroster
when rear window is fogged. Use the
conventional rearview mirror mode until
the rear window is fully defogged.
. The display of the Smart Rearview
Mirror may become hot. This is not a
malfunction.
. The color of an object in the distance or
in the dark may be difficult to be
recognized. This is not a malfunction.
System maintenance (Smart Rearview
Mirror):
. Always keep the mirror and camera area
of the rear window clean. .
Clean the mirror and the camera lens
with a dry soft cloth.
. When cleaning the camera area of the
rear window, use a soft cloth dampened
with water and a neutral detergent. Then
dry it with a dry soft cloth.

Mirror display screen is still unclear even
after cleaning the camera area of the
rear window, an oil film may be adhering
to the rear window glass. Clean the rear
window glass with an oil film remover.
. Never use alcohol, benzine, thinner, or
any similar material to clean the mirror or
camera lens. It will cause a discoloration,
deterioration or a system malfunction.
. Do not attach a sticker (including trans-
parent material) on the camera area of
the rear window.
OUTSIDE MIRRORS
WARNING
. Objects viewed in the outside mirror
on the passenger side are closer than
