required. Go to step 6.
5. If ªAIR BAGº warning lamp operates as shown in No. 1 in chart above, turn ignition switch ªOFFº to reset from Diagnosis mode
to User mode and to erase the memory of the malfunction.
Then go to step 6.
If ªAIR BAGº warning lamp operates as shown in No. 2 or No.
3 in chart above, the malfunctioning part is not repaired
completely, or another malfunctioning part is detected. Go to
DIAGNOSTIC PROCEDURE 6, page RS-48, and repair mal-
functioning part completely.
6. Turn ignition switch ªONº. ªAIR BAGº warning lamp operates in User mode. Compare ªAIR BAGº warning lamp operation to the
chart on the next page.
NOTE:
When a malfunction is detected, switch from Diagnosis mode
to user mode by turning the ignition switch as follows:

Service Notice
IWhen removing or installing various parts, place a cloth or padding onto the vehicle body to prevent
scratches.
I Handle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to oil
or damage them.
I Apply sealing compound where necessary when installing parts.
I When applying sealing compound, be careful that the sealing compound does not protrude from parts.
I When replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust pre-
vention measures.
Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS system composition which is available to NISSAN MODEL R20 is as follows (The compo-
sition varies according to the destination and optional equipment.):
IFor a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), front seat
belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
I For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of front
seat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a frontal
collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in the RSsection of this Service Manual.
WARNING:
I 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 per-
formed by an authorized NISSAN dealer.
I 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 the RS section.
I 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 covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
