Before driving
Back door
The back door can be
locked/unlocked and
opened by the following
procedures.
WARNING
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
■Caution while driving
●Keep the back door closed
while driving. If the back door is
left open, it may hit near-by
objects while driving or luggage
may be unexpectedly thrown
out, causing an accident.
In addition, exhaust gases may
enter the vehicle, causing death
or a serious health hazard.
Make sure to close the back
door before driving.
●Before driving the vehicle, make
sure that the back door is fully
closed. If the back door is not
fully closed, it may open unex-
pectedly while driving, causing
an accident.
●Never let anyone sit in the lug-
gage compartment. In the event
of sudden braking or a collision,
they are susceptible to death or
serious injury.
■When children ar e in the vehi-
cle
●Do not allow child ren to play in
the luggage compartment.
If a child is accidentally locked
in the luggage compartment,
they could have heat exhaus-
tion or other injuries.
●Do not allow a child to open or
close the back door.
Doing so may cause the back
door to move unexpectedly, or
cause the child’s hands, head,
or neck to be caught by the
closing back door.
■Operating the back door
●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 compartment.
