Read the following precautions when repairing HSS:
1.
Additional points to consider
• The repair of reinforcements (such as side members) by heat-
ing is not recommended, because it may weaken the compo-
nent. When heating is unavoidable, never heat HSS parts
above 550
°
C (1,022
°
F).
Verify heating temperature with a thermometer.
(Crayon-type and other similar type thermometer are appropri-
ate.)
• When straightening body panels, use caution in pulling any HSS panel. Because HSS is very strong,
pulling may cause deformation in adjacent sections of the body. In this case, increase the number of
measuring points, and carefully pull the HSS panel.
• When cutting HSS panels, avoid gas (torch) cutting if possible.
Instead, use a saw to avoid weakening surrounding areas due
to heat. If gas (torch) cutting is unavoidable, allow a minimum
margin of 50 mm (1.97 in).

< PRECAUTION >
[EXCEPT FOR EUROPE AND RUSSIA (RHD)]
REPAIRING HIGH STRENGTH STEEL
• When welding HSS panels, use spot welding whenever possi-
ble in order to minimize weakening surrounding areas due to
heat.
If spot welding is impossible, use MIG. welding. Do not use
gas (torch) for welding because it is inferior in welding
strength.
• Spot welding on HSS panels is harder than that of an ordinary
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:
• The electrode tip diameter must be sized properly according to
the metal thickness.
• The panel surfaces must fit flush to each other, leaving no
gaps.

CORROSION PROTECTION
Description
INFOID:0000000010499152
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 is adopted replacing conventional
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 parts are fabricated from galvannealed steel. Therefore, it is recommended that NISSAN
genuine parts or an equivalent be used for panel replacement to maintain the anti-corrosive performance 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 applied to
all body components.
CAUTION:
Confine paint removal during welding operation to an absolute
minimum.
NISSAN genuine parts are also treated in the same manner. Therefore, it is recommended that NISSAN gen-
uine parts or an equivalent be used for panel replacement to maintain anti-corrosive performance built into the
vehicle at the factory.
Anti-corrosive Wax
INFOID:0000000010499153
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.

CORROSION PROTECTION
Undercoating
INFOID:0000000010499154
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.
