Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001703112
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.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001843684
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Service Notice or PrecautionINFOID:0000000001703113
•Use recommended brake fluid when adding fluid to the clutch reservoir tank. Refer to MA-10.
•Never reuse fluid drained from clutch system.
•Be careful not to splash brake fluid on painted areas.
•Use new brake fluid to clean or wash all parts of master cylinder and operating cylinder.
•Never use mineral oils such as gasoline or kerosene. It will ruin the rubber parts of the hydraulic sys-
tem.
•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 AdjustmentINFOID:0000000001703117
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)

4. Adjust ASCD clutch switch (1), if equipped. Position so that
clearance between clutch pedal (2) and thread end of ASCD
clutch switch (1), with clutch pedal fully released, is within speci-
fication (A).
5. Check the clutch hydraulic system components (clutch master cylinder, clutch operating cylinder, clutch
withdrawal lever and clutch release bearing) 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 CL-8, "
Air
Bleeding Procedure".
NOTE:
Do not use a vacuum assist or any other type of power bleeder on this system. Use of a vacuum assist or
power bleeder will not purge all of the air from the system.

Air Bleeding ProcedureINFOID:0000000001703119
CAUTION:
Do not spill clutch fluid onto painted surfaces. If it spills, wipe up immediately and wash the affected
area with water.
NOTE:
• Do not use a vacuum assist or any other type of power bleeder on this system. Use of a vacuum assist or
power bleeder will not purge all the air from the system.
• Carefully monitor fluid level in reservoir tank during bleeding operation.
1. Fill master cylinder reservoir tank with new clutch fluid.
2. Connect a transparent vinyl tube and container to the bleeding
connector (1) on the CSC.
3. Depress and release the clutch pedal slowly and fully 15 times
at an interval of two to three seconds and release the clutch
pedal.
4. Bleed the air from the clutch system according to the following:
1. Push in the lock pin (1) of the bleeding connector (2), and
hold it in.
CAUTION:
Hold the lock pin in to prevent the bleeding connector
from separating when fluid pressure is applied.
2. Slide the clutch tube (1) away from the bleeding connector
to the specified distance (A) to allow air to bleed from the
clutch system.
3. Depress the clutch pedal and hold it down.
CAUTION:
Hold the clutch pedal down to prevent air from getting
back into the clutch system.
4. Return the clutch tube (1) and lock pin (2) to their original
positions.
5. Release the clutch pedal and wait for 5 seconds.
6. Repeat steps 3 to 6 until no bubbles are observed in the clutch fluid.
