Supplemental Restraint System (SRS) “AIR
BAG” and “SEAT BELT PRE-TENSIONER”
NLSC0001The 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 compo-
sition varies according to the destination and optional equipment.):
+For a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing 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.
+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 theRS sectionof 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 should be per-
formed by an authorized NISSAN dealer.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by intentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the RS section.
+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.

How to Handle BatteryNLSC0003CAUTION:
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-DISCHARGENLSC0003S01The following precautions must be taken to prevent over-discharg-
ing 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”.
MEL041F
+When the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal.
MEL042F
+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 LEVELNLSC0003S02WARNING:
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.
