Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EGS000IZ
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 per-
formed by an authorized NISSAN/INFINITI dealer.
●Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal 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 harness connec-
tors.
CautionEGS00049
●Always follow the warnings and the cautions below in disassembly procedures:
–Work in a clean, dust-free place. No dust proof device is necessary.
–Clean outside of unit before disassembly.
–Clean parts to be disassembled. Be careful not to allow any dirt or other foreign materials to enter or con-
tact with parts.
–Assemble disassembled parts properly, following order shown in manual. If work has been suspended in
the middle of assembly, place a clean cover over parts. This will prevent them from being contaminated.
–Use paper towels when removing dirt and other foreign materials. Cloth shop towels can leave lint on
cleaned parts that might affect operation of parts.
–Clean disassembled parts (except rubber parts) with kerosene. Drain oil by blowing with air or absorbing
with shop papers.
–Before assembling, apply Nissan power steering fluid to O-rings and seals.
–Replace gaskets and O-rings with new ones. Be careful not to damage any O-rings, oil seals, and gaskets
during assembly.
●If following part is scratched after disassembly of steering pump, replace applicable part: case, rear body,
side plate, pulley, rotor, vane, or flow control valve
●Mark source of fluid leak with a white marker for identification.
● Seals and copper washers must not be reused.
