WARNING
■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.
● Do not pull on the back door damper stay to close the back door, and do
not hang on the back door damper stay.
Doing so may cause hands to be caught or the back door damper stay to
break, causing an accident.
● If a bicycle carrier or similar heavy object is attached to the back door, it
may suddenly shut again after being opened, causing someone’s hands,
head or neck to be caught and injured. When installing an accessory part
to the back door, using a genuine Toyota part is recommended.
● 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.
● When closing the back door, take extra
care to prevent your fingers etc. from
being caught.
● When closing the back door, make sure
to press it lightly on its outer surface. If
the back door handle is used to fully
close the back door, it may result in
hands or arms being caught.

WARNING
■When operating the seats
Observe the following precautions. Failure to do so may result in death or
serious injury.
● Do not fold the seatbacks down while driving.
● Stop the vehicle on level ground, apply the parking brake firmly and shift
the shift position to P.
● Do not allow anyone to sit on a folded seatback.
● Do not operate the seat if it is occupied.

the seats during operation.

● After operation, rock the seat gently to ensure that it is firmly in place.
■ Reclining adjustment
● To reduce the risk of sliding under the lap belt during a collision, do not
recline the seat more than necessary.
If the seat is too reclined, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen, or your neck may contact the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.
● After adjusting the seat, make sure that the seat is locked in position.

Observe the following precautions. Failure to do so may result in death or
serious injury.
● Make sure that the seatback is securely locked in position by lightly push-
ing it back and forth.
● Check that the seat belts are not twisted or caught in the seatback.
● Re-couple the second center seat belt if it has been uncoupled. (P. 39)
● When using the seat belts, ensure that the seat belts are not in the seat
belt hangers. ( P. 193, 197)
