Precautions for Supplemental Restraint System
(SRS) “AIR BAG” and “SEAT BELT
PRE-TENSIONER”
NHST0001
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 sys-
tem 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 that is necessary to service the system safely is included in the RS section of this Service Manual.
WARNING:
I
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.
I
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 RS section.
I
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.
Precautions for Steering System
NHST0003
I
Before disassembly, thoroughly clean the outside of the unit.
I
Disassembly should be done in a clean work area. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
I
Place disassembled parts in order, on a parts rack, for easier and proper assembly.
I
Use nylon cloths or paper towels to clean the parts; common shop rags can leave lint that might
interfere with their operation.
I
Before inspection or reassembly, carefully clean all parts with a general purpose, non-flammable
solvent.
I
Before assembly, apply a coat of recommended power steering fluid* to hydraulic parts. Vaseline
may be applied to O-rings and seals. Do not use any grease.
I
Replace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during instal-
lation. Perform functional tests whenever designated.
*: Genuine Nissan PSF II or equivalent. Refer to MA-11, “Fluids and Lubricants”.
