tion, the supplemental air bag warning light
illuminates. The supplemental air bag warning
light will turn off after about 7 seconds if the
system is operational.
If any of the following conditions occur, the
supplemental front air bag, supplemental side
air bag and curtain side-impact air bag sys-
tems, and pre-tensioner seat belt need servic-
ing:
O The supplemental air bag warning light
remains on after approximately 7 seconds.
O The supplemental air bag warning light
flashes intermittently.
O The supplemental air bag warning light
does not come on at all.
Under these conditions, the supplemental front
air bags, supplemental side air bags, curtain
side-impact air bags and/or pre-tensioner seat
belt may not operate properly. They must be
checked and repaired. Take your vehicle to the
nearest authorized INFINITI retailer.
WARNINGIf the supplemental air bag warning light
is on, it could mean that the supplemen- tal front air bag, supplemental side air
bag, curtain side-impact air bag sys-
tems and/or pretensioner seat belt
will not operate in an accident.
Repair and replacement procedure The supplemental front air bags, supplemental
side air bags, curtain side-impact air bags and
pre-tensioner seat belts are designed to acti-
vate on a one-time-only basis. As a reminder,
unless it is damaged, the supplemental air bag
warning light will remain illuminated after infla-
tion has occurred. Repair and replacement of
these systems should be done only by an
authorized INFINITI retailer.
When maintenance work is required on the
vehicle, the supplemental front air bags, side
air bags, curtain side-impact air bags, related
parts and pre-tensioner seat belt should be
pointed out to the person conducting the main-
tenance. The ignition key should always be in
the LOCK position when working under the
hood or inside the vehicle. WARNING O Once the supplemental front air bag,
side air bag or curtain side-impact air
bag has inflated, the air bag module
will not function again and must be
replaced. Additionally, if any of the
supplemental front air bags inflate,
the activated pre-tensioner seat belt
must also be replaced. The air bag
module and pre-tensioner seat belt
system should be replaced by an au-
thorized INFINITI retailer. The air bag
modules and pre-tensioner seat belt
system cannot be repaired.
O The supplemental front air bag and
side air bag, curtain side-impact air
bag systems and pre-tensioner seat
belt system should be inspected by
an authorized INFINITI retailer if there
is any damage to the front end or side
portion of the vehicle.
O If you need to dispose of these
supplemental systems or scrap the
vehicle, contact an authorized
INFINITI retailer.

WARNINGO After adjustment, release the adjust-
ment button and try to move the
shoulder belt down to make sure it is
securely fixed in position.
O 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.
Shoulder belt guide (Coupe) The shoulder arm can be adjusted to allow
easier access to the shoulder belt. The arm
can also be folded down to allow rear seat
passengers easier access.
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 is available which is
compatible with the installed seat belts. The
extender adds approximately 8 inches (200
mm) of length and may be used for either the
driver or front passenger seating position. See your INFINITI retailer for assistance if the
extender is required.
WARNING O Only INFINITI belt extenders, made by
the same company which made the
original equipment belts, should be
used with INFINITI belts.
O Adults and children who can use the
standard seat belt should not use an
extender. Such unnecessary use
could result in serious personal in-
jury in the event of an accident.
O Never use seat belt extenders to in-
stall child restraints. If the child re-
straint is not secured properly, the
child could be seriously injured in a
collision or a sudden stop.
SEAT BELT MAINTENANCE O To clean the seat belt webbings, apply a
mild soap solution or any solution recom-
mended for cleaning upholstery or carpets.
Then brush the webbing, wipe it with a cloth
and allow it to dry in the shade. Do not allow SSS0222

air into the passenger compartment. The indi-
cator light on the button will come on.
Air recirculation Push the air recirculation button to recir-
culate interior air inside the vehicle. The indi-
cator light on the button will come on.
The air recirculation button will not be acti-
vated when the air conditioner is in DEF mode.
Air flow control (MODE) Pushing the MODE button selects the air outlet
to:
: Air flows from center and side ventila-
tors.
: Air flows from center and side ventila-
tors and foot outlets.
: Air flows mainly from foot outlets.
: Air flows from defroster and foot out-
lets.
To turn the system off Push the OFF button.
DUAL ZONE BUTTON (if so
equipped) You can set the temperature of the driver and front passenger sides individually.
Pushing the DUAL zone button changes the
setting position as follows:
Driver/Passenger ! Driver ! Passenger
If selecting the Driver/Passenger position
again after the temperature is individually set,
the display will show the temperature set for
the driver side.
AMBIENT TEMPERATURE The outside ambient temperature will be
shown on the center display.
The ambient temperature sensor is located in
front of the radiator. The sensor may be af-
fected by road or engine heat, wind direction
and other driving conditions. The display may
differ from the actual outside temperature or
the temperature displayed on various signs or
billboards.
OPERATING TIPS When the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for a
maximum of 150 seconds. However, this is not
a malfunction. After the coolant temperature
warms up, the air flow from the foot outlets will
operate normally. The sensor on the instrument panel helps
maintain a constant temperature; do not put
anything on or around this sensor.
IN-CABIN MICROFILTER The air conditioning system is equipped with a
in-cabin microfilter which collects dirt, pollen,
dust, etc. To make sure air conditioner heats,
defogs, and ventilates efficiently, replace the
filter in accordance with the maintenance
schedule in this manual. To replace the filter,
contact your INFINITI retailer.
The filter should be replaced if air flow
decreases significantly or if windows fog HA1011

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to yourself
or damage to the vehicle. The following are
general precautions which should be closely
observed.
WARNINGO Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
N (Neutral) position. For an automatic
transmission, move the selector lever
to P (Park) position.
O Be sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.
O If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.
O It is advised to secure or remove any loose clothing and any jewelry, such
as rings, watches, etc. before work-
ing on your vehicle.
O Always wear eye protection when-
ever you work on your vehicle.
O If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
O Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
O Keep smoking materials, flame and
sparks away from fuel and the bat-
tery.
O On gasoline engine models with the
Multiport Fuel Injection (MFI) System,
the fuel filter or fuel lines should be
serviced by an INFINITI retailer be-
cause the fuel lines are under high
pressure even when the engine is off. CAUTION O Do not work under the hood while the
engine is hot. Turn off the engine and
wait until it cools down.
O Never connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
O Never leave any engine or automatic
transmission related component har-
ness connector disconnected while
the ignition key is on.
O Avoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid.

tions regarding only those items which are
relatively easy for an owner to perform.
