Corrosion ProtectionNIS0020Z
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”
NFS000RO
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 CoverNFS000RP
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Brake SystemNFS000RQ

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”. Refer to MA-12, "Fluids and Lubricants" .

Never reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is splashed
on painted areas, wash it away with water immediately.

Use clean brake fluid, to clean or wash all parts of master cylinder and disc brake caliper, etc.

Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

Use flare nut torque wrench when installing brake tube.

When installing brake tube and hose, be sure to check torque.

Before working, turn ignition switch OFF and disconnect con-
nectors of ABS actuator and electric unit (control unit) or battery
cable from the negative terminal.

Burnish the brake contact surfaces after refinishing or replacing
rotors, after replacing pads, or if a soft pedal occurs at very low
mileage. Refer to BR-27, "
BRAKE BURNISHING PROCE-
DURE" (front disc brake), BR-33, "BRAKE BURNISHING PRO-
CEDURE" (rear disc brake).
WARNING:

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