PRECAUTIONS

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

INFOID:0000000001375288

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
system 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 necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.

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 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 harnesses or har-
ness connectors.

Service Notice or Precaution

INFOID:0000000001375289

• Use recommended brake fluid when adding fluid to the clutch reservoir tank. Refer to 

MA-19, "Fluids

and Lubricants"

.

• Do not reuse fluid drained from clutch system.
• Do not splash brake fluid on painted areas.
• Use new brake fluid to clean or wash all parts of master cylinder and operating cylinder.
• Do not use mineral oils such as gasoline or kerosene. It will ruin the rubber parts of the hydraulic

system.

• If transaxle assembly is removed from the vehicle, always replace CSC (Concentric slave cylinder).

Return CSC to original position to remove transaxle assembly. Dust on clutch disc sliding parts may
damage CSC seal and may cause clutch fluid leakage.

• Do not disassemble clutch master cylinder and CSC.

WARNING:

After cleaning clutch disc, clean it with a dust collector. Do not use compressed air.

On-vehicle Inspection and Adjustment

INFOID:0000000001375293

1.

Check to see if the master cylinder rod end moves freely. It
should not be bound by the clutch pedal.

a.

If the rod end does not move freely, check that the ASCD switch,
if equipped, is not applying pressure to the clutch pedal causing
the rod end to bind. To adjust, disconnect the ASCD switch elec-
trical connector and turn the ASCD switch.

b.

Connect the ASCD switch electrical connector, if equipped.

c.

Verify that the master cylinder rod end moves freely. It should
not be bound by the clutch pedal.

d.

If the rod end does not move freely, remove the rod end and
check for deformation or damage on the rod end. Leave the rod
end removed for step 2.

2.

Check the clutch pedal stroke for free range of movement.

a.

With the master cylinder rod end removed, manually move the pedal up and down to determine if it moves
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).

Clearance C 

: 0.74 - 1.96 mm (0.0291 - 0.0772 in)
