Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009549276
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 SR and SB section of
this Instruction.
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 SR section.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Instruction. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
General Precautions
INFOID:0000000009417418
WARNING:
After cleaning clutch disc, wipe it with a dust collector. Do not use compressed air.
CAUTION:
• Always use recommended clutch fluid. Refer to
MA-11, "Fluids and Lubricants"
.
• Do not reuse drained clutch fluid.
• Keep painted surface on the body and other parts free of clutch fluid. If fluid spills, wipe up immedi-
ately and wash the affected area with water.
• Do not use mineral oils, such as gasoline or kerosene. It will ruin the rubber parts of the hydraulic
system.
• Do not reuse CSC (Concentric Slave Cylinder). CSC slides back to the original position every time
when removing transaxle assembly. At this time, dust on the sliding parts may damage the seal of
CSC and may cause clutch fluid leakage. Refer to
CL-16, "Removal and Installation"
.
• Do not disassemble clutch master cylinder and CSC.

freely.
b. If any sticking is noted, replace the clutch pedal assembly. Re-verify that the master cylinder rod end
moves freely.
3. Adjust clutch interlock switch (1) position so that clearance
between clutch pedal (2) and thread end of clutch interlock
switch (1), with clutch pedal fully depressed, is within specifica-
tion (C).
4. Check the clutch hydraulic system components (clutch master cylinder, clutch pedal and CSC (Concentric
Slave Cylinder) for sticking or binding.
a. If any sticking or binding is noted, repair or replace the related parts as necessary.
b. If any hydraulic system repair was necessary, bleed the clutch hydraulic system. Refer to
