UNDERCOATING
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 preventive, soundproof, vibration-proof, shock-resistant, adhesive, and durable.
Precautions in undercoating
1. Do not apply undercoating to any place unless specified (such as the areas above the muffler and three
way catalyst which are subjected to heat).
2. Do not undercoat the exhaust pipe or other parts which become hot.
3. Do not undercoat rotating parts.
4. Apply bitumen wax after applying undercoating.

BODY CENTER MARKS

aged by an accident which might affect the vehicle frame (members, pillars, etc.), more accurate and effective
repair will be possible by using these marks together with body alignment specifications.

DESCRIPTION

All dimensions indicated in the figures are actual.

When using a tracking gauge, adjust both pointers to equal length. Then check the pointers and gauge
itself to make sure there is no free play.

When a measuring tape is used, check to be sure there is no elongation, twisting or bending.

Measurements should be taken at the center of the mounting holes.

An asterisk (*) following the value at the measuring point indicates that the measuring point on the other
side is symmetrically the same value.

The coordinates of the measurement points are the distances measured from the standard line of "X", "Y"
and "Z".
