Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS00311
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WAR NIN G:
lTo 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 must be per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper 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 SRS section.
lDo 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 connectors.
Wiring Diagrams and Trouble DiagnosisEKS00312
When you read wiring diagrams, refer to the followings:
lRefer toGI-14, "How to Read Wiring Diagrams"in GI section
lRefer toPG-2, "POWER SUPPLY ROUTING"for power distribution circuit in PG section
When you perform trouble diagnosis, refer to the followings:
lRefer toGI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES"in GI section
lRefer toGI-24, "How to Perform Efficient Diagnosis for an Electrical Incident"in GI section

How to Handle BatteryEKS00313
CAUTION:
lIf it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.
lAfter connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.
lNever add distilled water through the hole used to check specific gravity.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging a battery.
lThe battery surface (particularly its top) should always be kept
clean and dry.
lThe terminal connections should be clean and tight.
lAt every routine maintenance, check the electrolyte level.
This also applies to batteries designated as “low maintenance”
and “maintenance-free”.
lWhen the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal. (If the vehicle has
an extended storage switch, turn it off.)
lCheck 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
WA RN ING:
Do not allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, do not touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.

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 “sulphated”, note its voltage
and current when charging it. As shown in the figure, less cur-
rent 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 20°C(68°F).
Example:
lWhen electrolyte temperature is 35°C(95°F) and specific gravity
of electrolyte is 1.230, converted specific gravity at 20°C(68°F)
is 1.240.
lWhen electrolyte temperature is 0°C(32°F) and specific gravity
of electrolyte is 1.210, converted specific gravity at 20°C(68°F)
is 1.196.

CAUTION:
lSet 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.
lKeep battery away from open flame while it is being charged.
lWhen connecting charger, connect leads first, then turn on charger. Do not turn on charger first,
as this may cause a spark.
lIf battery temperature rises above 60°C (140°F), stop charging. Always charge battery when its
temperature is below 60°C(140°F).
