ing the air bag to be automatically turned
OFF. Certain sensors are used to meet the
requirements.
The occupant classification sensor in this
vehicle is a weight sensor. It is designed to
detect an occupant and objects on the
seat by weight. For example, if a child is in
the front passenger seat, the NISSAN Ad-
vanced Air Bag System is designed to turn
the front passenger air bag OFF in accor-
dance with the regulations. Also, if a child
restraint of the type specified in the regula-
tions is on the seat, its weight and the
child’s weight can be detected and cause
the air bag to turn OFF.
Front passenger seat adult occupants who
are properly seated and using the seat belt
as outlined in this manual should not
cause the front passenger air bag to be
automatically turned OFF. For small adults
it may be turned OFF, however if the occu-
pant takes his/her weight off the seat
cushion (for example, by not sitting upright,
by sitting on an edge of the seat, or by
otherwise being out of position), this could
cause the sensor to turn the air bag OFF.
Always be sure to be seated and wearing
the seat belt properly for the most effective
protection by the seat belt and supple-
mental air bag.NISSAN recommends that pre-teens and
children be properly restrained in a rear
seat. NISSAN also recommends that ap-
propriate child restraints and booster
seats be properly installed in a rear seat. If
this is not possible, the occupant classifica-
tion sensor is designed to operate as de-
scribed above to turn the front passenger
air bag OFF for specified child restraints as
required by the regulations. Failing to prop-
erly secure child restraints may allow the
restraint to tip or move in a collision or
sudden stop. This can also result in the
passenger air bag inflating in a crash in-
stead of being OFF. For additional informa-
tion, refer to “Child restraints” in this section.
If the front passenger seat is not occupied,
the front passenger air bag is designed not
to inflate in a crash. However, heavy objects
placed on the seat could result in air bag
inflation, because of the object’s weight de-
tected by the occupant classification sen-
sor. Other conditions could also result in air
bag inflation, such as if a child is standing
on the seat, or if two children are on the
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, de-
pending on the size of the child and the
type of child restraint being used. If the air
bag status light is not illuminated (indicat-
ing 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 properly and the occu-
pant is positioned properly. If the air bag
status light is still not illuminated, reposi-
tion the occupant or child restraint in a rear
seat.

REARVIEW MONITOR SYSTEM
LIMITATIONS
WARNING
Listed below are the system limitations
for RearView Monitor. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The system cannot completely elimi-nate blind spots and may not show
every object.
∙ Underneath the bumper and the cor- ner areas of the bumper cannot be
viewed on the RearView Monitor be-
cause of its monitoring range limita-
tion. The system will not show small
objects below the bumper, and may
not show objects close to the bumper
or on the ground.
∙ Objects viewed in the RearView Moni- tor differ from actual distance be-
cause a wide-angle lens is used.
∙ Objects in the RearView Monitor will appear visually opposite compared to
when viewed in the rearview and out-
side mirrors. ∙ Use the displayed lines as a reference.
The lines are highly affected by the
number of occupants, fuel level, ve-
hicle position, road conditions and
road grade.
∙ Make sure that the trunk is securely closed when backing up.
∙ Do not put anything on the rearview camera. The rearview camera is in-
stalled above the license plate.
∙ When washing the vehicle with high pressure water, be sure not to spray it
around the camera. Otherwise, water
may enter the camera unit causing
water condensation on the lens, a
malfunction, fire or an electric shock.
∙ Do not strike the camera. It is a preci- sion instrument. Otherwise, it may
malfunction or cause damage result-
ing in a fire or an electric shock.
The following are operating limitations and
do not represent a system malfunction: ∙ When the temperature is extremely high or low, the screen may not clearly
display objects. ∙ When strong light directly shines on the
camera, objects may not be displayed
clearly.
∙ Vertical lines may be seen in objects on the screen. This is due to strong re-
flected light from the bumper.
∙ The screen may flicker under fluores- cent light.
∙ The colors of objects on the RearView Monitor may differ somewhat from the
actual color of objects.
∙ Objects on the monitor may not be clear in a dark environment.
∙ There may be a delay when switching between views.
∙ If dirt, rain or snow accumulate on the camera, RearView Monitor may not dis-
play objects clearly. Clean the camera.

WARNING
∙ Do not leave children or adults whowould normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
∙ Properly secure all cargo to help pre- vent it from sliding or shif ting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
EXHAUST GAS (carbon monoxide)
WARNING
∙ Do not breathe exhaust gases; theycontain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death. ∙ If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
∙ Do not run the engine in closed spaces such as a garage.
∙ Do not park the vehicle with the en- gine running for any extended length
of time.
∙ Keep the rear vent windows, doors and trunk lids (if so equipped) closed
while driving, otherwise exhaust
gases could be drawn into the pas-
senger compartment. If you must
drive with one of these open, follow
these precautions:
1. Open all the windows.
2. Turn the air recirculation mode off and set the fan speed control to
the highest level to circulate the
air.
∙ The exhaust system and body should be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service. b. You suspect that exhaust fumes
are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system,
underbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
WARNING
∙ The exhaust gas and the exhaust sys-tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust system
components.
∙ Do not stop or park the vehicle over flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
