PRECAUTIONS
Revision: June 20062007 Versa
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ECS00GVW
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.
WAR NIN G:
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 harnesses or
harness connectors.
Service Notice or PrecautionsECS00FST
Use recommended brake fluid when adding fluid to the clutch reservoir tank. Refer to MA-11,
"RECOMMENDED FLUIDS AND LUBRICANTS".
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
system.
If transaxle assembly is removed from the vehicle, always replace CSC (Concentric slave cylin-
der). 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.
WAR NIN G:
After cleaning clutch disc, clean it with a dust collector. Do not use compressed air.

On-vehicle Inspection and Adjustment ECS00GVX
1. Check to see if the master cylinder rod end floats freely. It
should not be bound by the clutch pedal.
a. If the rod end is not free, check that the ASCD switch is not
applying pressure to the clutch pedal causing the rod end to
bind. To adjust, disconnect the ASCD switch electrical connector
and turn the ASCD switch.
b. Connect the ASCD switch electrical connector.
c. Verify that the master cylinder rod end floats freely. It should not
be bound by the clutch pedal.
d. If the rod end is still not free, remove the rod end and check for
deformation or damage. 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 floats
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)

CLUTCH PEDAL
Revision: June 20062007 Versa
4. Adjust ASCD clutch switch (1) position so that clearance
between clutch pedal (2) and thread end of ASCD clutch switch
(1), with clutch pedal fully released, is within specification (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.Clearance A : 0.74 - 1.96 mm (0.0291 - 0.0772 in)
