NISSAN Advanced Air Bag System
(front seats)
This vehicle is equipped with the NISSAN Ad-
vanced Air Bag System for the driver and front
passenger seats. This system is designed to meet
certification requirements under U.S. regulations. It
is also permitted in Canada. However, all of the
information, cautions and warnings in this
manual still apply and must be followed.
The driver supplemental front-impact air bag is
located in the center of the steering wheel. The
passenger supplemental front-impact air bag is
mounted in the dashboard above the glove box.
The front air bags are designed to inflate in higher
severity frontal collisions, although they may inflate
if the forces in another type of collision are similar to
those of a higher severity frontal impact. They may
not inflate in certain frontal collisions. Vehicle dam-
age (or lack of it) is not always an indication of
proper front air bag system operation.
The NISSAN Advanced Air Bag System has dual
stage inflators. It also monitors information from the
crash zone sensor, the Air bag Control Unit (ACU),
seat belt buckle sensors, occupant classification
sensor (pressure sensor) and passenger seat belt
tension sensor. Inflator operation is based on the
severity of a collision and seat belt usage for the
driver. For the front passenger, it additionally moni-
tors the weight of an occupant or object on the seat
and seat belt tension. Based on information from
the sensors, only one front air bag may inflate in a
crash, depending on the crash severity and
whether the front occupants are belted or un-
belted. Additionally, the front passenger air bag
may be automatically turned OFF under some con-
ditions, depending on the weight detected on the
passenger seat and how the seat belt is used. If the
front passenger air bag is OFF, the passenger air
bag status light will be illuminated (if the seat is
unoccupied, the light will not be illuminated, but the
air bag will be off). See “Front passenger air bag
and status light” later in this section for further
details. One front air bag inflating does not indicate
improper performance of the system.
