PRECONDITIONING

WARNING:

Disconnect high voltage. Refer to 

GI-33, "How to Disconnect High Voltage"

.

Check voltage in high voltage circuit. (Check that condenser are discharged.)

1. Lift up the vehicle and remove the battery under covers. Refer to 

EVB-181, "Exploded View"

.

2. Disconnect high voltage connector from front side of Li-ion battery. Refer to

Installation"

.

3. Measure voltage between high voltage harness connector termi-

nals.

DANGER:

 

 Touching high voltage components without using the

appropriate protective equipment will cause electrocution.

CAUTION:

For voltage measurements, use a tester which can measure to 500V or higher.

>> GO TO 6.

6.

REMOVE HIGH VOLTAGE PARTS AS AN ADDITIONAL WORK, ACCORDING TO THE SERVICE MANU-

AL

CORROSION PROTECTION

Description

INFOID:0000000010121691

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 protection, 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 GEN-

UINE NISSAN PARTS or an equivalent be used for panel replacement to maintain anti-corrosive performance

built into the vehicle at the factory.

Undercoating

INFOID:0000000010121692

The underside of the floor and wheelhouse are undercoated to prevent rust, vibration, noise and stone chip-

ping. Therefore, when such a panel is replaced or repaired, apply undercoating to that part. Use an undercoat-

ing which is rust resistant, soundproof, vibration-proof, shock-resistant, adhesive, and durable.

PRECAUTIONS IN UNDERCOATING

1. Never apply undercoating to any place unless specified (such as the areas above the muffler and three-

way catalyst that are subjected to heat).

2. Never undercoat the exhaust pipe or other parts that become hot.
3. Never undercoat rotating parts.
4. Apply bitumen wax after applying undercoating.
5. After putting seal on the vehicle, put undercoating on it.

CORROSION PROTECTION

Stone Guard Coat

INFOID:0000000010121693

To prevent damage caused by stones, the lower outer body panel (fender, door, etc.) have an additional layer

of Stone Guard Coating over the ED primer coating. When replacing or repairing these panels, apply Stone

Guard coating to the same portions as before. Use a coating which is rust preventive, durable, shock-resistant

and has a long shelf life.

Body Sealing

INFOID:0000000010121694

The following figure shows the areas that are sealed at the factory. Sealant that is applied to these areas

should be smooth and free from cuts or gaps. Care should be taken not to apply an excess amount of sealant

and not to allow other unaffected parts to come into contact with the sealant.
