INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:

Replace the O-ring of the low-pressure pipe 1 with a new one, then apply compressor oil to it when
installing it.

BODY REPAIR
Revision: 2004 November2004 FX35/FX45
lThe spot weld on HSS panels is harder than that of an ordi-
nary steel panel.
Therefore, when cutting spot welds on a HSS panel, use a
low speed high torque drill (1,000 to 1,200 rpm) to increase
drill bit durability and facilitate the operation.
2. Precautions in spot welding HSS
This work should be performed under standard working condi-
tions. Always note the following when spot welding HSS:
lThe electrode tip diameter must be sized properly according
to the metal thickness.
lThe panel surfaces must fit flush to each other, leaving no
gaps.
lFollow the specifications for the proper welding pitch.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AFS0028A
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 Brake SystemAFS001MQ

Recommended fluid is brake fluid “DOT 3”.

Do not reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas.

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

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

Use flare nut wrench when removing and installing brake tube.

When installing brake piping, be sure to check torque.

Before working, turn ignition switch OFF and disconnect con-
nectors for ABS actuator and electric unit (control unit) or battery
terminal.

Burnish the brake contact surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer to BR-24, "
BRAKE BURNISHING PROCEDURE" .
WARNING:

Clean brake pads and shoes with a waste cloth, then wipe
with a dust collector.SBR686C
