CAUTION
Operating the back door
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in death
or serious injury.
Remove any heavy loads, such as snow and ice, from the back door
before opening it. Failure to do so may cause the back door to suddenly
shut again after it is opened.
When opening or closing the back door, thoroughly check to make sure
the surrounding area is safe.
If anyone is in the vicinity, make sure they are safe and let them know that
the back door is about to open or close.
Use caution when opening or closing the back door in windy weather as it
may move abruptly in strong wind.
The back door may suddenly shut if it is
not opened fully. It is more difficult to
open or close the back door on an
incline than on a level surface, so
beware of the back door unexpectedly
opening or closing by itself. Make sure
that the back door is fully open and
secure before using the luggage com-
partment.
