Front passenger air bag
The front passenger air bag and front pas-
senger supplemental knee air bag are de-
signed to automatically turn OFF when the
vehicle is operated under some conditions
as described below in accordance with U.S.
regulations. If the front passenger air bag
and front passenger supplemental knee
air bag are OFF it will not inflate in a crash.
The driver air bag and other air bags in your
vehicle are not part of this system.
The purpose of the regulation is to help
reduce the risk of injury or death from an
inflating air bag to certain front passenger
seat occupants, such as children, by requir-
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 up to
the approximate size and weight of a one
year old is properly restrained in the front
passenger seat, the NISSAN Advanced Air
Bag System is designed to turn the front
passenger air bag and front passenger
supplemental knee air bag OFF. For a prop-
erly restrained child who is larger than the
approximate size and weight of a one yearold, the front passenger air bag and front
passenger supplemental knee air bag may
or may not be automatically turned OFF,
depending on the size of the child and the
type of child restraint being used. Af ter in-
stalling the child restraint and positioning
the child, place the ignition switch in the ON
position: if the front passenger air bag sta-
tus light is illuminated, the front passenger
air bag and front passenger supplemental
knee air bag are OFF. If the front passenger
air bag status light is not illuminated, the air
bag will inflate in a crash.
The front passenger seat belt sensors are
designed to detect if the seat belt is buck-
led. Based on the weight on the seat de-
tected by the occupant classification sen-
sor, the NISSAN Advanced Air Bag System
determines whether the front passenger
air bag and front passenger supplemental
knee air bag should be automatically
turned OFF as required by the regulations.
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 and
front passenger supplemental knee air
bag to be automatically turned OFF. For
small adults it may be turned OFF, however,
if the occupant does not sit in the seat
properly (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 front passen-
ger air bag and front passenger supple-
mental knee air bag OFF. Always be sure to
be seated and wearing the seat belt prop-
erly for the most effective protection by the
seat belt and supplemental 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 and front passenger supplemental
knee air bag OFF for specified child re-
straints as required by the regulations. Fail-
ing to properly secure child restraints and
to use the ALR mode may allow the re-
straint to tip or move in a collision or sud-
den stop. This can also result in the front
passenger air bag and front passenger
supplemental knee air bag inflating in a
crash instead of being OFF. For additional
information, see “Child restraints” (P. 1-26).

SECURITY SYSTEMS
Instruments and controls2-39

The system helps deter vehicle thef t but
cannot prevent it, nor can it prevent the
thef t of interior or exterior vehicle compo-
nents in all situations. Always secure your
vehicle even if parking for a brief period.
Never leave your keys in the vehicle, and
always lock the vehicle when unattended.
Be aware of your surroundings, and park in
secure, well-lit areas whenever possible.
Many devices offering additional protec-
tion, such as component locks, identifica-
tion markers, and tracking systems, are
available at auto supply stores and spe-
cialty shops. A NISSAN dealer may also offer
such equipment. Check with your insur-
ance company to see if you may be eligible
