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

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

NLSC0001

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER" 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 V10 is as follows (The composition varies according to the destination and optional equipment.): ¼ For a frontal collision The Supplemental Restraint System consists of driver air bag module (located in the center of the steering 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. ¼ For 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 the RS section of this Service Manual. WARNING: ¼ 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 should be performed by an authorized NISSAN dealer. ¼ Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by intentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the RS section. ¼ Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just before the harness connectors or for the complete harness are related to the SRS.

Wiring Diagrams and Trouble Diagnoses
When you read wiring diagrams, refer to the following: ¼ GI-11, "HOW TO READ WIRING DIAGRAMS" ¼ EL-12, "POWER SUPPLY ROUTING" for power distribution circuit When you perform trouble diagnoses, refer to the following: ¼ GI-32, "HOW TO FOLLOW TEST GROUP IN TROUBLE DIAGNOSES" ¼ GI-21, "HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT"

CAUTION: If it becomes necessary to start the engine with a booster battery 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. 3) Never add distilled water through the hole used to check specific gravity.

METHODS OF PREVENTING OVER-DISCHARGE

NLSC0003S01

The following precautions must be taken to prevent over-discharging a battery. ¼ The battery surface (particularly its top) should always be kept clean and dry. ¼ The terminal connections should be clean and tight. ¼ At every routine maintenance, check the electrolyte level. This also applies to batteries designated as "low maintenance" and "maintenance-free".
MEL040F

EC FE CL MT

¼

When the vehicle is not going to be used over a long period of time, disconnect the negative battery terminal.

AT AX SU BR

MEL041F

¼

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

NLSC0003S02

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

NLSC0003S0201

SEL709E

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.

SPECIFIC GRAVITY CHECK
1.

NLSC0003S03

Read hydrometer and thermometer indications at eye level.

MEL042FA

2. Convert into specific gravity at 20°C (68°F). Example: ¼ When 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. ¼ When 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.
