Body Front End
+When removing or installing hood, place a cloth or other padding on front fender panel and cowl top.
This prevents vehicle body from being scratched.
+Bumper fascia is made of plastic. Do not use excessive force and be sure to keep oil away from it.
+Hood adjustment: Adjust at hinge portion.
+Hood lock adjustment: After adjusting, check hood lock control operation. Apply a coat of grease to hood
locks engaging mechanism.
+Hood opener: Do not attempt to bend cable forcibly. Doing so increases effort required to unlock hood.
