PRECAUTIONS

Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
Supplemental Restraint System (SRS) AIR BAGand SEAT BELT PRE-TENSIONER
The Supplemental Restraint System “AIR BAG” and “SEAT BELT PRE-TENSIONER” used along with a seat belt, helps to reduce the risk of severe injury to the driver and front passenger in certain types of collisions. The Supplemental Restraint System consists of a driver air bag module (located in the center of the steering wheel), a front passenger air bag module (located on the instrument panel on the passenger side), seat belt pre-tensionsers, a diagnosis sensor unit, a crash zone sensor (4WD models), a warning lamp, wiring harness and spiral cable. Information necessary to service the system safely is included in the RS section of this Service Manual.
WARNING:
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance should be per­formed by an authorized NISSAN dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see RS section.
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses (except SEAT BELT PRE-TENSIONER) cov­ered with yellow insulation, either just before the harness connectors or for the complete harness, are related to the SRS.

The water temperature gauge indicates the engine coolant temperature. The reading on the gauge is based on the resistance of the thermal transmitter. The water temperature gauge is regulated by a variable ground signal supplied
to combination meter terminal 19 through thermal transmitter terminal 1.
As the temperature of the coolant increases, the resistance of the thermal transmitter decreases and the needle on the gauge moves from C to H.
TACHOMETER
NGEL0042S02
The tachometer indicates engine speed in revolutions per minute (rpm). The tachometer is regulated by a signal
to combination meter terminal 21 for the tachometer from ECM terminal 3.
SPEEDOMETER
NGEL0042S04
The vehicle speed sensor provides a voltage signal to the combination meter for the speedometer. The voltage is supplied
to combination meter terminals 22 and 23 for the speedometer from vehicle speed sensor terminals 1 and 2.
The unified meter control unit converts the voltage to the vehicle speed and displays it on the speedometer.
