PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS00001
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 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.
Precautions for Battery ServiceNFS00002
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Precautions for Procedures without Cowl Top CoverNFS000HT
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Brake SystemNFS00003

Recommended fluid is brake fluid “DOT 3”. Refer to MA-11, "Fluids and Lubricants" .

Do not reuse drained brake fluid.

Do not let brake fluid come in contact with painted surfaces on the body. This might damage the paint, so
if it does come in contact, immediately wipe area and wash off with water.

To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.

Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

Inspection after Disassembly
Master cylinder

Check that there is no damage, friction, rusting, or pinholes on the cylinder inner wall, and replace if there
are any non-standard conditions.
Assembly
CAUTION:

Do not use mineral oils such as kerosene, gasoline during the cleaning and assembly process.

Make sure there is no foreign matter such as dirt or dust attached to the inner cylinder walls, the
piston, or the cap seal, and use care to avoid damaging parts with the assembly tools.

Do not drop parts. If a part is dropped, do not use it.
1. Apply brake fluid to cylinder inner wall body and contact surface
of the piston assembly.
2. Insert the secondary piston assembly and primary piston
assembly into cylinder body in this order.
CAUTION:

Do not reuse the primary and secondary piston assem-
blies.

Be sure to replace the assembly without disassembling
the new inner kit.

Pay attention to the orientation of the piston cup, and
insert straight to prevent the cup from being caught by
cylinder inner wall.
3. Perform a visual inspection of the secondary piston slit through
the tank boss hole on the secondary-side of the cylinder body,
and install the piston stopper.
4. Holding down the piston with the stopper cap, push the stopper
cap tabs so they are firmly into the cylinder grooves, then attach
the stopper cap.
CAUTION:
Do not reuse the stopper cap.
5. Apply brake fluid the grommet and attach to the cylinder body.
CAUTION:
Do not reuse the grommet.
6. Attach the attachment in the inner kit to the reservoir cap as
described in disassembly step 2.
7. Master cylinder assembly is fixed in the vise as described in
disassembly step 3.SBR089C

5. Push in the primary piston and remove the piston stopper from
the cylinder body secondary-side tank boss hole.
6. Remove the snap ring while pushing the primary piston in to pre-
vent the piston from popping out.
7. Holding the primary piston rod, pull the primary piston assembly,
the plate, and the guide straight out.
8. Remove the plate and guide from the primary piston.
CAUTION:
When removing the plate from the primary piston rod, make
sure the inside of the plate does not damage the rod.
9. Tap flange using a soft block such as wood, and carefully pull
the secondary piston assembly straight out to prevent cylinder
inner wall from being damaged.

Do not drop parts. If a part is dropped, do not use it.
1. Apply brake fluid to cylinder inner wall body and contact surface
of the piston assembly, and apply the silicon grease in the inner
kit to the primary piston rod.
2. Insert the secondary piston and primary piston into cylinder
body in this order.
