CAUTION
■Caution while driving
Keep the back door closed.
This not only keeps personal belongings from being thrown out, but also pre-
vents exhaust gases from entering the vehicle.
■ When children are in the vehicle
● Never leave children unattended in the vehicle as they may lock them-
selves in the vehicle or back door, which could cause the child to overheat
or suffocate, resulting in death or serious injury.
● Do not allow a child open or close the back door. Doing so may cause the
back door to operate unexpectedly and part of the child’s body may
become caught.

■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( P. 64)
■ Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult

CAUTION
■Seat belt pretensioners
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the seat belt becomes locked: it cannot
be further extended, nor will it return to the stowed position. The seat belt
cannot be used again and must be replaced at your Toyota dealer.
■ Using a seat belt extender
● Do not wear the seat belt extender, if you can fasten the seat belt without
the extender.
● Do not use the seat belt extender when installing a child restraint system,
because the belt will not securely hold the child restraint system, increas-
ing the risk of death or injury in the event of a collision.
● The personalized extender may not be safe on another vehicle, when
used by another person, or at a different seating position other than the
one originally intended.
NOTICE
■When using a seat belt extender
When releasing the seat belt, press on the buckle release button on the
extender, not on the seat belt.
This helps prevent damage to the vehicle interior and the extender itself.

dent, resulting in death or serious injury.
● Do not adjust the mirrors.
● Do not drive with the mirrors folded back.
● Before driving, be sure to extend mirrors and make an adjustment prop-
erly.
