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.
IFor 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 theRS sectionof this Service Manual.
WARNING:
ITo 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.
IImproper 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.
IDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow harness connector.
Wiring Diagrams and Trouble Diagnoses
When you read wiring diagrams, refer to the following:
IGI-10, ªHOW TO READ WIRING DIAGRAMSº
IEL-6, ªPOWER SUPPLY ROUTINGº for power distribution circuit
When you perform trouble diagnoses, refer to the following:
IGI-25, ªHOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSESº
IGI-22, ªHOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENTº
PRECAUTIONS

How to Handle Battery
CAUTION:
If it becomes necessary to start the engine with a booster bat-
tery and jumper cables,
1) Use a 12-volt booster battery.
2) After connecting battery cables, ensure that they are
tightly clamped to battery terminals for good contact.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharg-
ing a battery.
IThe battery surface (particularly its top) should always be kept
clean and dry.
IThe terminal connections should be clean and tight.
IAt every routine maintenance, check the electrolyte level.
This also applies to batteries designated as ªlow maintenanceº
and ªmaintenance-freeº.
IWhen the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal.
ICheck the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep
a close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Do not allow battery fluid to come in contact with skin, eyes,
fabrics, or painted surfaces. After touching a battery, do not
touch or rub your eyes until you have thoroughly washed your
hands. If acid contacts eyes, skin or clothing, immediately
flush with water for 15 minutes and seek medical attention.

IRemove the cell plug using a suitable tool.
IAdd distilled water up to the MAX level.
Sulphation
A battery will be completely discharged if it is left unattended
for a long time and the specific gravity will become less than
1.100. This may result in sulphation on the cell plates.
To determine if a battery has been ªsulphatedº, note its volt-
age and current when charging it. As shown in the figure, less
current and higher voltage are observed in the initial stage of
charging sulphated batteries.
A sulphated battery may sometimes be brought back into ser-
vice by means of a long, slow charge, 12 hours or more, fol-
lowed by a battery capacity test.
SPECIFIC GRAVITY CHECK
1. Read hydrometer and thermometer indications at eye level.
2. Convert into specific gravity at 20ÉC (68ÉF).
Example:
IWhen electrolyte temperature is 35ÉC (95ÉF) and specific grav-
ity of electrolyte is 1.230, converted specific gravity at 20ÉC
(68ÉF) is 1.240.
IWhen electrolyte temperature is 0ÉC (32ÉF) and specific grav-
ity of electrolyte is 1.210, converted specific gravity at 20ÉC
(68ÉF) is 1.196.

CAUTION:
ISet charging current to value specified in Fig. 2. If charger is not capable of producing specified
current value, set its charging current as close to that value as possible.
IKeep battery away from open flame while it is being charged.
IWhen connecting charger, connect leads first, then turn on charger. Do not turn on charger first,
as this may cause a spark.
IIf battery temperature rises above 60ÉC (140ÉF), stop charging. Always charge battery when its
temperature is below 60ÉC (140ÉF).
