A HOOD KINK PREVENTATIVE CAUTION
Remember that it is always best that you personally open or close your own hood. Always pull the hood toward you when opening and push away from you when closing. Use sufficient force to make it work as smoothly as possible. Make sure that your pivot points are occasionally oiled and that your hood springs are in proper shape.
