head, or neck to be caught by the
closing back door.
■Operating the back door
Observe the following precau-
tions. 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

closing the back door in windy
weather as it may move
abruptly in strong wind.
●Vehicles without a power back

denly shut if it is not opened
fully. It is more difficult to open

back door is fully open and
secure before using the luggage
compartment.
●Vehicles with a power back
