Before operating the power back door,
make sure there is nobody near the back
door.
The resistance must be as strong as the
force of the moving door, or stronger. As
the back door approaches the fully−closed
or fully −opened position, its moving force
increases significantly.
The jam protection function may not work
if something gets caught just before the
back door is fully closed.
If the back door receives a strong impact,
this function may operate even if nothing
is caught.CAUTION
The power back door could injure
people if they are caught in the door
path. When using the power back
door, observe the following:
Never try jamming any part of your
body to make the jam protection
function work intentionally.
The jam protection function may
not work if something gets caught
just before the sliding door is fully
closed.
Before you close the power back
door, always make sure there is no-
body around it. If someone’s neck,
head or hands get caught in a clos-
ing door, it could result in a seri-
ous injury. When anyone closes the
power back door, make sure he or
she operates the door safely.
NOTICE
Objects caught in the path of the
back door may be damaged. Make
sure there is nothing in the doorway
before closing the back door.
