2011 NISSAN Consumer Safety & Air Bag Information Guide 2
THE NISSAN ADVANCED AIR BAG SYSTEM
All 2011 NISSAN vehicles are equipped with the NISSAN Advanced Air Bag System
(AABS) for the driver and front passenger seats. Typically, this system, which has dual-
stage inflators,* monitors information from various crash sensors, the front seat belt buckle
sensors, and the occupant classification sensor.
The front passenger air bag may be automatically turned off under some conditions,
depending on the pressure or weight detected by sensors in the passenger seat. See the
vehicle owner’s manual for more information. If the front passenger air bag is off, the front
passenger air bag status light will be illuminated.**
The front passenger air bag status light does not indicate a malfunction of the front
passenger air bag. If the front passenger air bag status light is illuminated while the seat is
occupied by an adult, the occupant may need to shift his or her seating position so the
system can turn on the front passenger air bag and turn off the status light.
Remember, all air bags are supplemental restraint systems. You must always use seat belts
and child restraints properly, as explained in the vehicle owner’s manual and your child
restraint manufacturer’s instructions.
THE MOST IMPORTANT PART OF AN AIR BAG: YOUR SEAT BELT
Your chances of surviving a collision will improve greatly if one simple piece of advice is
followed: always wear your seat belt. Do not count on just the air bags for occupant
protection; they are merely a supplemental restraint system.
Seat belts help to protect the occupants of your vehicle during collisions in which the air
bags are not designed to activate. Moreover, in situations where the air bags are activated,
seat belts enhance their effectiveness and can help reduce the risk of injury from an
inflating air bag. Seat belts will also help protect the occupants of your vehicle during
multiple-impact collisions, while the air bags work only one time if a collision is severe
enough to activate them. Please see the SEAT BELT SAFETY and CHILD SAFETY
sections of this guide and the vehicle owner’s manual for more information.
*Dual-stage inflators vary the inflation rate based on the severity of the collision (for example, less
forceful inflation for moderate impacts and a high force of inflation for more severe impacts). In
addition, based on information from the seat belt buckle sensors that detect whether the seat belts
are fastened, the deployment of the front air bags is adjusted. Only one front air bag may inflate in a
crash, depending on the crash severity, and whether the front occupants are belted or unbelted.
**When the system detects that the seat is unoccupied, the passenger air bag status light will not
illuminate even though the front passenger air bag is OFF.

EFFECTIVE USE OF SEAT BELTS AND AIR BAGS
Seat belts and supplemental air bags are most effective when vehicle occupants are sitting
upright and well back in the seat with both feet on the floor. Keep in mind that air bags
inflate with great force. Being unrestrained, leaning forward, sitting sideways, or being out
of position in any way puts you at a greater risk of injury or death in a crash. You may also
receive serious or fatal injuries from the air bag system if you are up against it when it
inflates. Always sit back against the seatback with both feet on the floor and as far away as
practical from the steering wheel or dashboard and always wear your seat belt. Please see
the SEAT BELT SAFETY section of this guide and the vehicle owner’s manual for more
information.
HOW AND WHEN FRONT AIR BAGS WORK
While the inner workings of a supplemental front air bag system are complicated,
understanding what makes the front air bags deploy is rather easy: the vehicle’s front air
bag sensor system is designed to detect rapid deceleration usually associated with
moderate to severe frontal collisions within a limited range of angles. The vehicle’s
deceleration rate is related to various factors, such as speed of the vehicles involved, the
weight and stiffness of the vehicles/objects involved, contact locations, and the angle of
impact, to name a few. Once the sensor system is activated, the front air bags inflate with a
harmless gas almost instantly.
