CAUTION
■
While driving
Observe the following precautions while driving.
Failure to do so may cause a door to open unexpectedly and an occupant to
fall out of the vehicle, resulting in death or serious injury.
● Ensure that all doors are properly closed.
● Always lock the doors.
● Set the sliding door child-protector locks when children are seated in the
vehicle.
● Always use a seat belt.
● Do not operate the inside handle of the doors while driving.
■ When children are in the vehicle
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Do not leave children alone in the vehicle.
If a child is accidentally locked in the vehicle, they could have heat
exhaustion.
● Do not allow a child to open or close the sliding door.
Doing so may cause the sliding door to move unexpectedly, or cause the
child’s hands, head, or neck to be caught by the moving sliding door.

CAUTION
■When folding the rear seatbacks down
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, set the parking brake and shift the shift
lever to P.
● Do not allow anyone to sit on a folded seatback or in the luggage compart-
ment while driving.
● Do not allow children to enter the luggage compartment.
● Be careful not to get any part of your body pinched by a seat.
■ Seat 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 reclined too far, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen, or your neck may contact the shoul-
der belt, increasing the risk of death or serious injury in the event of\
an acci-
dent.
Adjustments should not be made while driving as the seat may unexpectedly
move and cause the driver to lose control of the vehicle.

Seat belt pretensioners (front seats)
The pretensioner helps the seat
belt to quickly restrain the occu-
pant by retracting the seat belt
when the vehicle is subjected to
certain types of severe frontal
collision.
The pretensioner does not acti-
vate in the event of a minor frontal
impact, a side impact, a rear
impact or a vehicle rollover.
Pre-collision seat belts (front seats of vehicles with pre-collision
system)If the pre-collision sens or detects that a collision is unavoidable, the
pre-collision system w ill retract the seat belt , thus enhancing the
effectiveness of the seat be lt pretensioner in a crash.
The same will happen if the driver makes an emergency braking or loses
control of the vehicle. (P. 336)
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also
lock if you lean forward too quickly. A slow, easy motion will allow the belt to
extend so that you can move around fully.
■ Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then
retracted even slightly, the belt is locked in that position and cannot be
extended. This feature is used to hold the child restraint system (CRS) firmly.
To free the belt again, fully retract the belt and then pull the belt out once
more. ( P. 194)

■Pregnant women
■ People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( P. 128)
■ Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult
size.
● Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle’s seat belt. ( P. 189)
● When the child becomes large enough to properly wear the vehicle’s
seat belt, follow the instructions on P. 128 regarding seat belt usage.
■ Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate
for the first collision, but will not activate for the second or subsequent colli-
sions.
Obtain medical advice and wear the seat
belt in the proper way. ( P. 128)
Women who are pregnant should position
the lap belt as low as possible over the
hips in the same manner as other occu-
pants. Extend the shoulder belt com-
pletely over the shoulder and position the
belt across the chest. Avoid belt contact
over the rounding of the abdominal area.
If the seat belt is not worn properly, not
only a pregnant woman, but also the fetus
could suffer death or serious injury as a
result of sudden braking or a collision.

CAUTION
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failing to do so may cause death or severe injury.
■Wearing a seat belt
● Ensure that all passengers wear a seat belt.
● Always wear a seat belt properly.
● 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.
● Toyota recommends that children be seated in the rear seat and always
use a seat belt and/or an appropriate child restraint system.
● To achieve a proper seating position, do not recline the seat more than
necessary. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.
● Always wear the belt with the shoulder portion over the outside armrest
and the lap portion under the outside armrest.
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.
