The SRS air bags activate in the event of a front or side impact in which the vehicle occupants may be severely injured even if they are wearing the seat belts properly.
They may not activate when the crash energy is absorbed and/or distributed by the vehicle body. Vehicle damage (or lack of it) is not always an indication of proper SRS air bag system operation.
When the SRS air bag will deploy

The supplemental front-impact air bag system is designed to inflate in higher severity frontal collisions. Some examples are shown in the following illustrations.
JVR0423X
The supplemental front-impact air bag system will deploy in the event of an impact which exceeds a 25 km/h (16 MPH) frontal collision with a solid wall that does not move or deform.
The supplemental front-impact air bag system may also deploy when the vehicle receives severe damage to the undercarriage.

. Landing hard on the ground after jumping Supplemental side-impact and curtain side- impact air bags (if equipped):GUID-9E14C2E6-2E9C-4731-980B-C45B899B977B
The supplemental side-impact and curtain side-impact air bag systems are designed to inflate in higher severity side collisions. Some examples are shown in the following illustra- tions.

side-impact air bags will deploy in the event of a side impact with a normal passenger vehicle that exceeds at a speed of 25 km/h (16 MPH).
When the SRS air bag is unlikely to deploy
PD23A1-D9E3985E-CC2E-439B-91C9-EBECFF8D69A6The SRS air bags may not deploy in cases where the impact is not forceful enough to inflate the SRS air bags.
For example, if the vehicle strikes an object, such as a parked vehicle or sign pole, which can move or deform on impact, the SRS air bags are Safety — seats, seat belts and supplemental restraint system

PRE-TENSIONER SEAT BELT SYSTEM
PD23A1-CCC50FE5-1806-4BDE-8644-BB3B516367C8WARNING:
. The pre-tensioner seat belt cannot be reused after activation. It must be re- placed together with the retractor and buckle as a unit.
. If the vehicle becomes involved in a collision but the pre-tensioner is not activated, be sure to have the pre-ten- sioner system checked and, if necessary, replaced by a NISSAN dealer.
. No unauthorized changes should be made to any components or wiring of the pre-tensioner seat belt system. This is to prevent accidental activation of the pre-tensioner seat belt or damage to the pre-tensioner seat belt system.
. Work around or on the pre-tensioner seat belt system should be done by a NISSAN dealer. The SRS wiring should not be modified or disconnected. Unauthorized electrical test equipment and probing devices should not be used on the pre- tensioner seat belt system.
. If you need to dispose of the pre-ten- sioner seat belt system, or scrap the vehicle, contact a NISSAN dealer. Correct pre-tensioner disposal procedures are set forth in the appropriate NISSAN Ser- vice Manual. Incorrect disposal proce- dures could cause personal injury.
The pre-tensioner seat belt system may acti- vate with the supplemental air bag system in certain types of collisions. Working with the seat belt retractor and anchor, it helps tighten the seat belt the instant the vehicle becomes involved in certain types of collisions, helping to restrain occupants.
The pre-tensioner is encased with the front seat belt’s retractor and anchor. These seat belts are used the same as conventional seat belts.
When the pre-tensioner seat belt activates, a fairly loud noise may be heard, followed by the release of smoke. This smoke is not harmful and does not indicate a fire. Care should be taken not to inhale it, as it may cause irritation and choking. Those with a history of a breath- ing condition should get fresh air promptly.
