BODY REPAIR
The following figure shows the areas which are sealed at the factory. Sealant which has been 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.

A mark has been placed on each body panel to indicate the parts matching positions. When repairing parts
damaged by an accident which might affect the vehicle stru cture (members, pillars, etc.), more accurate and
effective repair will be possible by using these ma rks 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 su re 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 poi nt 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 ″.
