seat, contrary to the instructions in this
manual. Always be sure that you and all
vehicle occupants are seated and re-
strained properly.
Using the front passenger air bag status
light, you can monitor when the front pas-
senger air bag is automatically turned OFF
with the seat occupied. The light will not
illuminate when the front passenger seat is
unoccupied.
If an adult occupant is in the seat but the
front passenger air bag status light is illu-
minated (indicating that the air bag is OFF),
it could be that the person is a small adult,
or is not sitting on the seat properly or not
using the seat belt properly.
If a child restraint must be used in the front
seat, the front passenger air bag status light
may or may not be illuminated, depending
on the size of the child and the type of child
restraint being used. If the air bag status light
is not illuminated (indicating that the air bag
might inflate in a crash), it could be that the
child restraint or seat belt is not being used
properly. Make sure that the child restraint is
installed properly, the seat belt is used prop-
erly and the occupant is positioned properly.
If the air bag status light is not illuminated,
reposition the occupant or child restraint in a
rear seat.
If the front passenger air bag status light
will not illuminate even though you believe
that the child restraint, the seat belts and
the occupant are properly positioned, the
system may be sensing an unoccupied
seat (in which case the air bag is OFF). A
NISSAN dealer can check that the system is
OFF by using a special tool. However, until
you have confirmed with a dealer that your
air bag is working properly, reposition the
occupant or child restraint in a rear seat.
The NISSAN Advanced Air Bag System and
front passenger air bag status light will
take a few seconds to register a change in
the passenger seat status. For example, if a
large adult who is sitting in the front pas-
senger seat exits the vehicle, the front pas-
senger air bag status light will go from OFF
to ON for a few seconds and then to OFF.
This is normal system operation and does
not indicate a malfunction.
If a malfunction occurs in the front passen-
ger air bag system, the supplemental air
bag warning light
, located in the me-
ter and gauges area of the instrument
panel, will blink. Have the system checked. It
is recommended that you visit a NISSAN
dealer for this service. Other supplemental front-impact air
bag precautions
WARNING
• Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause in-
jury if the front air bags inflate.
• Immediately af ter inflation, several
front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.
• No unauthorized changes should be
made to any components or wiring
of the supplemental air bag system.
This is to prevent accidental inflation
of the supplemental air bag or dam-
age to the supplemental air bag
system.
• Do not make unauthorized changes
to your vehicle's electrical system,
suspension system or front end
structure. This could affect proper
operation of the front air bag system.

FUEL GAUGE
The gauge indicates theapproximatefuel
level in the tank.
The gauge may move slightly during brak-
ing, turning, acceleration, or going up or
down hills.
The gauge needle returns to 0 (Empty) af-
ter the ignition switch is placed in the OFF
position.
The low fuel warning light comes on when
the amount of fuel in the tank is getting low.
Refill the fuel tank before the gauge reg-
isters 0 (Empty). The

is located on the driver's side of the vehicle.
Malfunction Indicator Light (MIL) may
come on. Refuel as soon as possible.
Af ter a few driving trips, the
light
should turn off. If the light remains on
af ter a few driving trips, have the ve-
hicle inspected. It is recommended
that you visit a NISSAN dealer for this
service.
• For additional information, refer to
“Malfunction Indicator Light (MIL)” in
this section.
DISTANCE TO EMPTY (DTE)
Displays the estimated distance the ve-
hicle can be driven before refueling. The
value is calculated based on recent fuel
economy, the amount of fuel remaining in
the fuel tank, and the actual fuel consump-
tion.
Changes in driving patterns or conditions
can cause the DTE value to vary. As a result,
the value displayed may differ from the ac-
tual distance that can be driven. DTE display will change to “---” when the
fuel level in the tank is getting low, prior to
the fuel gauge reaching 0 (Empty).
NOTE:
• The DTE value af ter refill is estimated
based on recent fuel economy and
amount of fuel added.
• If a small amount of fuel is added, or the ignition is on during refueling, the
display may not be updated.
• Conditions that affect the fuel economy will also affect the estimated
DTE value (city/highway driving, idle
time, remote start time, terrain, sea-
sonal weather, added vehicle weight,
added deflectors, roof racks, etc.).
