WARNING
■To prevent an accident
Observe the following precautions while driving the vehicle.
Failure to do so may result in a door opening and an occupant falling out,
resulting in death or serious injury.
● Ensure that all doors are properly closed and locked.
● Do not pull the inside handle of the doors while driving.
Be especially careful for the front doors, as the doors may be opened
even if the inside lock buttons are in locked position.
● Set the rear door child-protector locks when children are seated in the rear
seats.
■ When opening or closing a door
Check the surroundings of the vehicle such as whether the vehicle is on an
incline, whether there is enough space for a door to open and whether a
strong wind is blowing.
When opening or closing the door, hold the door handle tightly to prepare
for any unpredictable movement.
■ When using the wireless remote control and operating the power win-
dows
Operate the power window after checking to make sure that there is no pos-
sibility of any passenger having any of their body parts caught in the win-
dow. Also, do not allow children to operate the wireless remote control. It is
possible for children and other passengers to get caught in the power win-
dow.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■Before driving
● Make sure that the trunk lid is fully closed. If the trunk lid is not fully closed,
it may open unexpectedly while driving and hit near-by objects or luggage
in the trunk may be thrown out, causing an accident.
● Do not allow children to play in the trunk.
If a child is accidentally locked in the trunk, they could suffer from heat
exhaustion, suffocation or other injuries.
● Do not allow a child to open or close the trunk lid.
Doing so may cause the trunk lid to open unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing trunk lid.
■ Important points while driving
Never let anyone sit in the trunk. In the event of sudden braking or a colli-
sion, they are susceptible to death or serious injury.

WARNING
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in seri-
ous injury.
● Remove any heavy loads, such as snow and ice, from the trunk lid before
opening it. Failure to do so may cause the trunk lid to suddenly shut again
after it is opened.
● When opening or closing the trunk lid, 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 trunk is about to open or close.
● Use caution when opening or closing the trunk lid in windy weather as it
may move abruptly in strong wind.
● Do not attach any accessories other than genuine Toyota parts to the trunk
lid. Such additional weight on the trunk lid may cause the lid to suddenly
shut again after it is opened.
●The trunk lid may suddenly shut if it is
not opened fully. It is more difficult to
open or close the trunk lid on an incline
than on a level surface, so beware of
the trunk lid unexpectedly opening or
closing by itself. Make sure that the
trunk lid is fully open and secure before
using the trunk.
● When closing the trunk lid, take extra
care to prevent your fingers, etc., from
being caught.
● When closing the trunk lid, make sure to
press it lightly on its outer surface. If the
trunk handle is used to fully close the
trunk lid, it may result in hands or arms
being caught.
