Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

                                             Supplemental Restraint System (SRS) "AIR
                                             BAG" and "SEAT BELT PRE-TENSIONER"                               NEEL0001
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER" used along with
a seat belt, help to reduce the risk or severity of injury to the driver and front passenger in a frontal collision.
The Supplemental Restraint System consists of air bag modules (located in the center of the steering wheel
and in the instrument panel on the passenger side), seat belt pre-tensioners, a diagnosis sensor unit, warn-
ing lamp, wiring harness, and spiral cable.
The vehicle (except Crew Cab model) is equipped with a passenger air bag deactivation switch. Because no
rear seat exists where a rear-facing child restraint can be placed, the switch is designed to turn off the pas-
senger air bag so that a rear-facing child restraint can be used in the front passenger seat. The switch is
located in the center of the instrument panel, near the ashtray. When the switch is turned to the ON position,
the passenger air bag is enabled and could inflate in a frontal collision. When the switch is turned to the OFF
position, the passenger air bag is disabled and will not inflate in a frontal collision. A passenger air bag OFF
indicator on the instrument panel lights up when the passenger air bag is switched OFF. The driver air bag
always remains enabled and is not affected by the passenger air bag deactivation switch.
Information necessary to service the system safely is included in the RS section of this Service Manual.
