Seat belt pretensioners (front seats)
The pretensioners help 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 pretensioners do not activate
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 will 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. 340)
■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. 196)

■Pregnant women
■ People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( P. 129)
■ 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. 191)
● When the child becomes large enough to properly wear the vehicle’s
seat belt, follow the instructions on P. 129 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. 129)
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.

CAUTION
■When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious injuries
that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
■ 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 SRS warning light will come on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
■ Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of protection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or accident. ( P. 130)

CAUTION
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to be
jammed in the door.
● Inspect the seat belt system periodically. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt until it is replaced. Damaged seat
belts cannot protect an occupant from death or serious injury.
● Ensure that the belt and tab are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact your Toyota
dealer.
● Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there is no obvious damage.
● Do not attempt to install, remove, modify, disassemble or dispose of the
seat belts. Have any necessary repairs carried out by your Toyota dealer.
Inappropriate handling of the pretensioner may prevent it from operating
properly resulting in death or serious injury.
