and even death.
Caution
Before opening the tailgate, check overhead obstructions, e.g. a
garage door, to avoid damage to
the tailgate. Always check the
moving area above and behind the
tailgate.
Note
The installation of certain heavy
accessories onto the tailgate may
affect its ability to remain open.
Note
