Stone Guard Coat

INFOID:0000000010499754

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:0000000010499755

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.

Description

• This section is prepared for technicians who have attained a high level of skill and experience in repairing

collision-damaged vehicles and also use modern service tools and equipment. Persons unfamiliar with body
repair techniques should not attempt to repair collision-damaged vehicles by using this section.

• Technicians are also encouraged to read the Body Repair Manual (Fundamentals) in order to ensure that the

original functions and quality of the vehicle are maintained. The Body Repair Manual (Fundamentals) con-
tains additional information, including cautions and warnings, that are not including in this manual. Techni-
cians should refer to both manuals to ensure proper repair.

• Please note that this information is prepared for worldwide usage, and as such, certain procedures might not

apply in some regions or countries.

REPLACEMENT OPERATIONS

• Front pillar butt joint can be determined anywhere within shaded

area as shown in the figure. The best location for the butt joint is at
position A due to the construction of the vehicle.

• Determine cutting position and record distance from the locating

indent. Use this distance when cutting the service part. Cut outer
front pillar over 60 mm (2.36 in) above the inner front pillar cut
position.

• Prepare a cutting jig to make outer pillar easier to cut. Also, this will

permit the service part to be accurately cut at the joint position.

• An example of cutting operation using a cutting jig is as per the fol-

lowing.

1.

Mark cutting lines.
A: Cut position of outer pillar
B: Cut position of inner pillar

2.

Align cutting line with notch on jig. Clamp jig to pillar.

3.

Cut outer pillar along groove of jig (at position A).

4.

Remove jig and cut remaining portions.

5.

Cut inner pillar at position B in same manner.

Welding of Ultra High Strength Steel

INFOID:0000000010499787

SPOT WELDING

The spot welding is limited to ultra high strength steel of tensile strength 980 MPa under the conditions listed
below.

CAUTION:

• If this condition is not satisfied, then perform plug welding.
• This condition is inapplicable to ultra high strength steel of tensile strength more than 980 MPa. For

this type of ultrahigh strength steel, perform plug welding.

• Since this condition is applicable only to this vehicle (J11), never apply it to welding conditions of

other vehicles.

Welding condition

PLUG WELDING

To weld ultra high strength steel of tensile strength 980 MPa or more, perform plug welding observing the
welding hole diameter described in the manual.

CAUTION:

• To perform plug welding, use fuel mixture (Ar 80% + CO2 20%) for shielding gas of welder. 
• If carbon dioxide gas (CO2 100%) is used for shielding gas of welder, adequate weld strength cannot

be secured. For this reason, always use fuel mixture for shielding gas of welder to prevent.

• When welding hole diameter cannot be satisfied, make multiple holes (smaller diameter) so that the

sum of hole areas becomes equal to the area of the specified weld hole.
