WARNING

Observe the following precautions.
Failure to do so may result in death or serious injury.

■

Before driving

●

Make sure that the back door is fully closed. If the back door is not fully
closed, it may open unexpectedly while driving and hit near-by objects or
luggage in the luggage compartment may be thrown out, causing an acci-
dent.

●

Do not allow children to play in the luggage compartment.
If a child is accidentally locked in the luggage compartment, they could
have heat exhaustion or other injuries.

●

Do not allow a child to open or close the back door.
Doing so may cause the back door to open unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing back door.

■

Important points while driving

●

Keep the back door closed while driving.
If the back door is left open, it may hit near-by objects or luggage in the

Never let anyone sit in the luggage compartment. In the event of sudden
braking, sudden swerving or a collision, they are susceptible to death or
serious injury.

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.
