perature.
The restoration time may become
shorter when the coating is warmed by
applying warm water.

etc. cannot be restored.

restoring coat.

ate) and wax that contains abrasives.

may scratch the vehicle surface, parts
(wheel, etc.) and damage the paint.
●When it is necessar y to set the engine
switch to ACC with the shift position held
