NOTE: Do not paint ground point (3) where attachment bolt (4) is seated.

Customers concern can be resolved by sanding off paint at ground point (3) where attachment bolt (4) is seated. After installing the bolt (4), apply touch-up paint to the exposed base material area of the front fender stay.

NEWLY INSTALLED FRONT FENDER STAY NOTE:

CAUTION: If the bolt (4) contact area (3) is painted when the front fender stay (2) is newly replaced, it could cause a malfunction in the PCM. Before painting a newly replaced part, protect the bolt (4) contact area (3) with masking tape (5) as shown in the figure.
