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.

Air Bleeding ProcedureECS00FSY
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.
CAUTION:

Carefully monitor fluid level in reservoir tank during bleeding operation.

Keep painted surface of body and other parts free of clutch fluid. If it spills, wipe up immediately
and wash the affected area with water.

First bleed the air from the operating cylinder air bleed
valve (1) and then from the bleed connector air bleed valve.
1. Connect a transparent vinyl tube and container to the air bleeder
valve on the clutch operating cylinder.
2. Fill reservoir tank with new clutch fluid.
3. Depress and release the clutch pedal slowly and fully 15 times
at an interval of 2 to 3 seconds.
4. With pedal depressed, continue the bleeding procedure.
5. Push the lock pin (1) of the bleeding connector (2) into the
locked position.
CAUTION:
Hold it to prevent releasing clutch tube from bleeding con-
nector (2) when fluid pressure is applied in the tube.
6. Slide clutch tube (1) in the direction of the arrow as shown, then
bleed the air from the tube.
7. Return clutch tube (1) and lock pin (2) to their original positions.
8. Release clutch pedal and wait for 5 seconds.
9. Repeat steps 2 to 8 until no bubbles are observed in the clutch
fluid.

REMOVAL
1. Use one of the following methods to remove hose from master cylinder.

Drain clutch fluid from reservoir tank and remove hose.

Remove hose from master cylinder. Immediately plug hose and reservoir tank to prevent clutch fluid
from dripping.
CAUTION:
Keep painted surface of the body and other parts free of clutch fluid. If it spills, wipe up immedi-
ately and wash the affected area with water.
2. Remove master cylinder rod end from clutch pedal assembly.
3. Remove lock pin (1) from connector of master cylinder (2) and
separate clutch tube (3).
4. Rotate master cylinder clockwise by 45° and remove from the vehicle.
INSTALLATION
1. Tilt master cylinder clockwise by 45° and insert it in the mounting
hole. Rotate counterclockwise to secure it. At this time, nipple is
