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 CA TIONIC ELECTRODEPOSITION PRIMER
A phosphate coating treatment and a cationic electrode posit ion primer, which provide excellent corrosion pro-
tection, are employed on all body components.
CAUTION:
Confine paint removal during weld ing 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 repl acement to maintain anti-corrosive performance built
into the vehicle at the factory.
ANTI-CORROSIVE WAX
To improve corrosion resistance, anti-corrosive wax is applied inside the body sill and inside other closed sec-
tions. Accordingly, when replacing these parts, be sure to apply anti-corrosive wax to the appropriate areas of
the new parts. Select an excellent anti-corrosive wax which will penetrate after application and has a long shelf
life.

BODY REPAIR
1. When repairing and painting a portion of the body adjacent to plastic parts, consider their characteristics
(influence of heat and solvent) and remove them if neces sary or take suitable measures to protect them.
2. Plastic parts should be repaired and painted using methods suiting the materials
, characteristics.

5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for Brake SystemINFOID:0000000005928387
• Refill using recommended brake fluid. Refer to MA-14.
• Never reuse drained brake fluid.
• Be careful not to splash brake fluid on painted surface of body. If brake fluid is splashed on painted surfaces of body immediately wipe it off with cloth and then wash it away with water.
• To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.
• Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
• Use a flare nut wrench when removing a brake tube and use a flare nut torque wrench when installing a brake tube.
• When installing brake tubes and hoses, be sure to check torque.
• Before working, turn igniti on switch OFF and disconnect connec-
tors of ABS actuator and electric unit (control unit) or the battery
cable from the negative terminal.
• Burnish the new braking surfaces after refinishing or replacing drums or rotors, after replacing p ads or linings, or if a soft pedal
occurs at very low mileage. Refer to BR-34, "
Brake Burnishing

CHECKING BRAKE FLUID LEVEL
• Make sure the fluid level in the reservoir tank is within the standard (between MAX and MIN lines).
• Visually check around the reservoir tank for fluid leaks.
• If fluid level is excessively low, check brake system for fluid leaks.
• Release parking brake lever and see if brake warning lamp goes off. If not, check brake system for fluid leaks.
Drain and RefillINFOID:0000000005928394
CAUTION:
• Refill using recommended brake fluid. Refer to MA-14, "
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, immediately wipe th em with cloth and wash it away with water.
• Before working, disconnect connect ors of ABS actuator and electric unit (control unit) or battery
negative terminal.
1. Connect a vinyl tube to bleed valve.
2. Depress the brake pedal, loosen the bleed valve, and gradually remove the brake fluid.
3. Clean inside of reservoir tank, and refill with new brake fluid.
4. Loosen bleed valve, depress brake pedal slowly to full stroke and then release it. Repeat the procedure every 2 or 3 seconds
until the new brake fluid comes out, then close the bleed valve
while depressing the brake pedal . Repeat the same procedure
for each wheel.
5. Bleed the air from the brake hydraulic system. Refer to BR-9,
"Bleeding Brake System" .
Bleeding Brake SystemINFOID:0000000005928395
CAUTION:
• While bleeding, pay attention to master cylinder fluid level.
• Before working, disconnect connectors of ABS actuator and electri c unit (control unit) or the battery
cable from the negative terminal.
1. Connect a vinyl tube to the rear right bleed valve.
2. Fully depress brake pedal 4 to 5 times.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005928426
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 severi ty 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 w hether 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 inoper ative, 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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.
Precaution for Brake SystemINFOID:0000000005928427
CAUTION:
• Refer to MA-14
for recommended brake fluid.
• 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.
• To clean or wash all parts of master cylin der and disc brake caliper, use clean brake fluid.
• Never use mineral oils such as gasoline or kerosen e. They will ruin rubber parts of the hydraulic sys-
tem.
• Use flare nut wrench when removing and installing brake tube.
• If a brake fluid leak is found, the part must be disassembled
without fail. Then it has to be replaced with a new one if a
defect exists.
• Turn the ignition switch OFF and remove the connector of the
ABS actuator and electric unit (con trol unit) or the battery ter-
minal before performing the work.
• Always torque brake lines when installing.
• Burnish the brake contact surf aces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage. Refer to BR-34, "
Brake Burnishing Proce-
dure".
WARNING:
• Clean brake pads and shoes with a waste cl oth, then wipe with a dust collector.
