CAUTION

Wipe off any anticorrosion agent which oozes out onto 
surfaces to be painted later; the presence of such anticor-
rosion agent would prevent correct adhesion of the paint 
coat.
21.Application of an anticorrosion agent

Apply an ample amount of anticorrosion agent to any 
welded areas and to all surfaces from which the paint coat 
was removed.
The paint coat of welded areas will have been damaged by 
the heat; be sure to apply an anticorrosion agent to surfaces 
to be repaired.
Use an aerosol-type anticorrosion agent for application to 
the side sills, the pillars, and other similar parts which have a 
hollow construction, by utilizing the trim mounting holes, etc.

22.Application of undercoating

If the underbody is repaired or replaced, carefully apply a 
coating of undercoating as described in the section (of the 
manual corresponding to that model).

CAUTIONS REGARDING BODY REPAIR

Because each component part of a single-unit con-
struction body makes some contribution, more or 
less, to the overall strength of that body, it is neces-
sary to sufficiently understand the actual function of 
any part to be repaired before attempting any repair 
or welding procedure.

.

STRENGTH AND RIGIDITY

1. The suspension installation part plays an impor-

tant role, determining the wheel alignment. Wheel 
misalignment is of course potentially very danger-
ous because it can lead to driving instability, 
one-sided braking, abnormal tire wear, abnormal 
vibration, etc.
At the time of repair, it is particularly necessary to 
take measurements at the components noted 
below, and to make all welds and installations 
with special care.

• Front sidemember

• Rear floor sidemember

• Front wheelhouse (inner)

• Rear wheelhouse (inner) (Independent rear 

suspension type)

2. Because the places where the floor panel and 

sidemember parts are joined have an important 
effect upon the rigidity of the entire body, welds in 
these places must be done with particular care.

3. After repairs have been completed, the wheel 

alignment, wheel base, tread, etc., must be care-
fully checked to be sure that there is no deviation.

.

SAFETY

1. Procedures related to the installation of any com-

ponent related to safety must be done with partic-
ular care in order to assure full maintenance of 
safety.

• Suspension installation parts

• Fuel pipe

• Brakes

• Fuel tank installation parts, etc.

2. Because seat belts are directly related to driver 

and passenger safety, any welds of seat belt 
anchor points or reinforcements must be done 
with particular care in order to maintain strength.

.

PREVENTION OF CORROSION AND OF 
WATER OR DUST ENTRY

1. After any work is completed, it is important to 

completely remove any welding residue, particles 
or residue from cutting, and any other dirt, etc.

2. Corrosion-prevention material must without fail 

be applied at the following places:

• At any place where paint has flaked off or 

peeled away.

• At any surfaces that have been cut.

• At the outer and inner side of every welded 

place.

• Within any semi-enclosed structure or compo-

nent (aerosol-type rust inhibitors are effective 
for difficult-to-reach places).

• At the outer and inner side of any place sub-

jected to heat.

3. Apply a coating of undercoating if the underbody 

is repaired.

4. Use spot sealer if spot welds are made.
5. Repair any scratches to panels made by mold-

ings, sashes, etc.

6. Carefully apply body sealant to panel connection 

joints and other fitting places.

7. Tape over any unused holes in the panel inner 

side by using sealing tape.

.

VIBRATION AND NOISE

1. Prevent any decrease of tensional rigidity caused 

by welding distortion.

2. Carefully apply body sealant to panel connection 

joints and other fitting places.

3. Tape over any unused holes in the panel inner 

side by using sealing tape.

.

CONTACT AND ALIGNMENT

1. In order to maintain the precision of openings, 

make careful measurements as repairs are being 
made.

2. Make contact/alignment adjustments of door 

hinge, lid, and hood hinge installation parts.

THEFT PROTECTION

M4090007000067

In order to prevent theft, following Vehicle Identification Number 
(VIN) has been engraved and attached, in the form of a label to 
the engine, transaxle, and main of the outer body:

Engine cylinder block, Transaxle housing, Fender, 
Doors, Quarter panel, Hood, Liftgate, Trunk lid, 
Bumpers

Furthermore, supplementary parts for the main portions of the 
outer body have theft protection labels attached and the sup-
plementary parts for the engine and the transaxle are engraved 
with the same details.

PANEL REPAIR CAUTION

1. Take care when respraying the original part to cover the theft 

protection label with masking tape prior to respraying. In 
addition, remember to peel off the masking tape after 
completion of the respray.

2. Because theft protection labels on the supplementary parts 

are covered with masking tape already, they can be 
resprayed just as they are.

3. Take care not to peel off the theft protection labels from 

either the original or the supplementary parts.

HOW TO PEEL OFF THE SURFACE MASKING 
FILM FROM THE THEFT-PROTECTION LABEL

CAUTION

Be careful not to damage the paint surface or the label 
itself.
1. Using a sharp knife at the corner of the label surface, lift up 

the masking film only.

2. Grasp the masking film and peel it all off.
NOTE: If the masking film tears, repeat from step 1. Use the 
knife, however, to lift the opposite corner of the label, rather 
than trying to continue peeling from the place where it tore.

ATTACHMENT OF SILENCERS

M4090009000052

Silencers (petroleum-asphalt sheets) are attached to 
the upper surface of the floor and at the interior side 
of the dash panel in order to absorb vibrations and 
shut out exhaust gas heat. If these silencers are 
peeled off in the course of replacement or repair of a 

welded panel, cut and attach replacement material 
(in the shape shown in the figure). For detailed infor-
mation concerning the locations where silencers are 
to be attached for individual models, refer to the 
manual for that model.

1. Heat the "silencer layer" (petroleum-asphalt sheet) with a 

blow drier to soften it.
