Before driving
CAUTION
nSeat adjustment
lDo not recline the seat more than necessary when the vehicle is in motion
to reduce the risk of sliding under the lap belt.
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.
l After adjusting the seat, make sure that the seat is locked in position.
n After returning the seatback
Push and pull the seatback to confirm that it is securely locked.
n Caution while driving

nSeat adjustment
lDo not recline the seat more than necessary when the vehicle is in motion
to reduce the risk of sliding under the lap belt. 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.
l After adjusting the seat, make sure that the seat is locked in position.
n After returning the seatback to the upright position
Observe the following precautions. Failure to do so may result in death or
serious injury.
l Make sure that the seatback is securely locked in position by lightly rock-
ing it back and forth.
l Check that the seat belts and buckles are not twisted or caught under the
seat.
l Arrange the seat belts in the proper positions for ready use.
NOTICE

CAUTION
nWearing a seat belt
Observe the following precautions to reduce the risk of injury in the event of
sudden braking or an accident.
Failing to do so may cause death or severe injury.
lEnsure that all passengers wear a seat belt.
l Always wear a seat belt properly.
l Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
l Toyota recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
l Do not recline the seat any more than necessary to achieve a proper seat-
ing position. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
l Do not wear the shoulder belt under your arm.
l Always wear your seat belt low and snug across your hips.
n 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 your seat belts cannot be fastened
securely because they are not long
enough, a personalized seat belt
extender is available from your Toyota
dealer free of charge.

Before driving
CAUTION
nUsing a seat belt comfort guide
lAlways make sure the shoulder belt is positioned across the center of the
shoulder. The belt should be kept away from the neck, and should not fall
off the shoulder.
Failure to observe these precautions could reduce the effectiveness of the
seat belt in an accident, causing death or serious injury.
n Using a seat belt extender
lDo not wear the seat belt extender, if you can fasten the seat belt without
the extender.
l 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 serious injury in the event of a collision.
l 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
nWhen 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.
