Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER” AKS00B6K
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.
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 section.
●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 harness connectors.

How to Handle Battery |
AKS00BHF |
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.
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”.
MEL040F
●When the vehicle is not going to be used over a long period of time, disconnect battery cable at negative terminal.
ELA0349D
●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:
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.
●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 current and higher voltage are observed in the initial stage of charging sulphated batteries.
A sulphated battery may sometimes be brought back into service by means of a long, slow charge, 12 hours or more, followed by a battery capacity test.

CHARGING THE BATTERY
CAUTION:
●Do not “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. Do not 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).

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 indicates 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.

CAUTION:
When working with batteries, always wear appropriate eye protection.
NOTE:
● To ensure a complete and thorough diagnosis, the battery, starter and generator test segments must be B done as a set from start to finish.
●If battery surface charge is detected while testing, the tester will prompt you to turn on the headlamps to
|
remove the surface charge. |

● |
JIS: Japanese Industrial Standard. |
|
When using the battery tester: Use the CCA rating only.
● |
The tester requires the CCA rating for the battery be entered |
|
|
|
exactly as it is written or stamped on the battery. |
|
|
● |
U.S. market: Refer to the latest “Battery Testing” Technical |
PKIC1310E |

|
|
listed by vehicle. |
|
|
● You must not use the JIS rating.
6.Using the arrow and “ENTER” keys alternately, select the battery type and rating.
NOTE:
The tester lists five choices; CCA, JIS, IEC, DIN, and EN. Use only the CCA choice .
