from the slot in the hood and return the prop to its re-
tainer.
2. Lower the hood until it approaches about 12 in (30

locked.
If this does not close the hood, release it from a slightly
higher position. Do not push the hood forcibly to close
it. It could deform the metal.
Always check that the hood is properly locked
before you start driving. If it is not, it might fly
open while the vehicle is moving and block
your view, which may cause an accident and
serious bodily injury.
