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

INFOID:0000000009267718

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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS

system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front

air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.

Information necessary to service the system safely is included in the SR and SB sections of this Service Man-

ual.

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 SR section.

• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this

Service Instruction. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-

ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a

hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing

serious injury.

• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

How to Handle Battery

INFOID:0000000009267721

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.)

BATTERY DIAGNOSIS WITH EXP-800 NI OR GR8-1200 NI

To diagnose and confirm the condition of the battery, use the following special service tools:

• EXP-800 NI Battery and electrical diagnostic analyzer

• GR8-1200 NI Multitasking battery and electrical diagnostic station

NOTE:

Refer to the applicable Instruction Instruction for proper battery diagnosis procedures.

BATTERY DIAGNOSIS WITHOUT EXP-800 NI OR GR8-1200 NI

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.

Failure to do this may cause personal injury or damage to clothing or the painted surfaces.

• Remove the cell plug using a suitable tool.

• Add distilled water up to the MAX level.

SULFATION

• 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 sulfation on the cell plates.

• To determine if a battery has been “sulfated”, 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 sulfated batteries.

• A sulfated 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

NOTE:

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.
1. Read hydrometer and thermometer indications at eye level.
2. Use the chart below to correct your hydrometer reading accord-

ing to electrolyte temperature.
