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

INFOID:0000000001731064

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 AIRBAG” and
“SEAT BELT” 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 must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.

• Do 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 and/or orange harnesses or har-
ness connectors.

How to Handle Battery

INFOID:0000000001723097

CAUTION:

• If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt

booster battery.

• After connecting battery cables, ensure that they are tightly clamped to battery terminals for good

contact.

• Never 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.

• The battery surface (particularly its top) should always be kept

clean and dry.

• The terminal connections should be clean and tight.
• At every routine maintenance, check the electrolyte level.

This also applies to batteries designated as “low maintenance” and
“maintenance-free”.

• When the vehicle is not going to be used over a long period of

time, disconnect the battery cable from the negative terminal. (If
the vehicle has an extended storage switch, turn it off.)

• Check 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:

Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, never 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.

BATTERY

• Remove the cell plug using a suitable tool.
• Add 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 “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.

Use the chart below to correct your hydrometer reading accord-
ing to electrolyte temperature.

CHARGING THE BATTERY

CAUTION:

• Never “quick charge” a fully discharged battery.
• Keep the battery away from open flame while it is being charged.
• When connecting the charger, connect the leads first, then turn on the charger. Never turn on the

charger first, as this may cause a spark.

• If battery electrolyte temperature rises above 55 

°

C (131 

°

F), stop charging. Always charge battery at

a temperature below 55 

°

C (131 

°

F).

Charging Rates

Do not charge at more than 50 ampere rate.

NOTE:
The ammeter reading on your battery charger will automatically decrease as the battery charges. This indi-
cates that the voltage of the battery is increasing normally as the state of charge improves. The charging amps
indicated above refer to initial charge rate.
• If, after charging, the specific gravity of any two cells varies more than 0.050, the battery should be replaced.
