Corrosion ProtectionNIS001Q8
DESCRIPTION
To provide improved corrosion prevention, the following anti-corrosive measures have been implemented in
NISSAN production plants. When repairing or replacing body panels, it is necessary to use the same anti-cor-
rosive measures.
Anti-Corrosive Precoated Steel (Galvannealed Steel)
To improve repairability and corrosion resistance, a new type of anti-
corrosive precoated steel sheet has been adopted replacing conven-
tional zinc-coated steel sheet.
Galvannealed steel is electroplated and heated to form Zinc-iron
alloy, which provides excellent and long term corrosion resistance
with cationic electrodeposition primer.
Nissan Genuine Service Parts are fabricated from galvannealed steel. Therefore, it is recommended that
GENUINE NISSAN PARTS or equivalent be used for panel replacement to maintain the anti-corrosive perfor-
mance built into the vehicle at the factory.
Phosphate Coating Treatment and Cationic Electrodeposition Primer
A phosphate coating treatment and a cationic electrodeposition primer, which provide excellent corrosion pro-
tection, are employed on all body components.
CAUTION:
Confine paint removal during welding operations to an absolute
minimum.
Nissan Genuine Service Parts are also treated in the same manner. Therefore, it is recommended that GENU-
INE NISSAN PARTS or equivalent be used for panel replacement to maintain anti-corrosive performance built
into the vehicle at the factory.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS000LN
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 Procedures without Cowl Top CoverNFS000LO
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Brake SystemNFS000LP
Clean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.
Recommended fluid is brake fluid “DOT 3”. MA-12, "Fluids and Lubricants" .
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 new brake fluid.
Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
Use a flare nut torque wrench when 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
cables.
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" (Front disc
brake), BR-31, "
Brake Burnishing Procedure" (Rear disc brake).
WARNING:
Clean brake pads and shoes with a waste cloth, then clean with a dust collector.

5.5 mm (0.217 in) or more.
Replace brake pedal assembly if any non-standard condition is
detected.
Check clevis pin and plastic stopper for damage and deforma-
tion. Replace clevis pin if there are.

BRAKE TUBE AND HOSEPFP:46210
Hydraulic CircuitNFS000LX
CAUTION:
All brake hoses and tubes must be free from excessive bending, twisting and pulling.
Make sure there is no interference with other parts when turning steering both clockwise and
counterclockwise.
The brake tubes and hoses is an important safety part. If a brake fluid leak is detected, always dis-
assemble the parts. Replace applicable part with a new one, if necessary.
Be careful not to splash brake fluid on painted areas; it way cause paint damage. If brake fluid is
splashed on painted surfaces of body, immediately wipe it off and them wash it away with water
immediately.
Do not bend or twist brake hose sharply, or strongly pull it.
When removing components, cover brake line connections so that no dirt, no dust, or other for-
eign matter gets in.
Refill with new brake fluid “ DOT 3 ”.
Do not reuse drained brake fluid.
Removal and Installation of Front Brake Tube and Brake Hose NFS000LY
REMOVAL
1. Drain brake fluid. Refer to BR-9, "Drain and Refill" .
2. Using a flare nut wrench, remove brake tube from brake hose.
3. Remove union bolt and remove brake hose from caliper assembly.
4. Remove lock plate and remove brake hose from vehicle.
INSTALLATION
1. Position brake hose by aligning with the protrusion on caliper assembly, and them tighten union bolt to the specified torque.
CAUTION:
Do not reuse copper washer.
