Side Structure Reinforcement
1. The thickness of the reinforcements of the front pillar and center pillar has been increased to improve
collision safety.
2. The front pillar reinforcement upper, side outer panel, and front roof rail have been joined to improve
twisting rigidity.
3. The side sill has been made thin by employing a variable thickness steel sheet* for the center pillar
reinforcement to improve safety in collision and realize lightweight.
4. The cross section of the side sill outer reinforcement has been made large to improve safety in
collision and body rigidity.
5. A rear pillar reinforcement has been added, and the rear shelf and rear wheel house have been
joined to improve the twisting rigidity of the suspension attaching portion.
NOTE
*: Steel sheets with different thickness welded to form one steel sheet.

BODY CONSTRUCTION -Locations Using Urethane Foam and Foam MaterialA-22
LOCATIONS USING URETHANE FOAM AND FOAM MATERIAL
1. Urethane foam is inserted into the center pillar to prevent the penetration of noise.
2. By filling the top of the front pillar, bottom of the front pillar, center pillar, side roof rail, rear pillar
and inside the wheel house arch with foam acoustic material, penetration of noise is prevented.
Precautions on performing work involving sheet metal at locations using foam material
As foam may burn when heated, observe the following precautions.
1. Do not perform heating work using gas burners at locations using foam material.
2. When cutting locations using foam material, use tools (air saw, etc.) which do not generate
heat.
3. If leftover foam material is present at the area to be cut (body side), remove the foam around
the area to be welded before proceeding with welding.

BODY CONSTRUCTION -Stiffener and Dump Sheet Application LocationsA-24
STIFFENER AND DUMP SHEET APPLICATION LOCATIONS
Stiffener is pasted to the inside of the side outer panel, and dump sheets are pasted on the inside
of the front doors to increase surface rigidity, thus improving soundproof qualities with the anti-vibration
effects.
NOTE
The stiffener comes in sheet form and is composed mainly of epoxy resin, glass fibers, and fillers. It hardens
when heated. It is used to improve the rigidity of outer panels.
