■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. 137)
■ Pregnant women
Obtain medical advice and wear the seat
belt in the proper way. ( P. 85)
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 serious 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 the same time, including children.
● Toyota recommends that children should be seated in the rear seat and
always use a seat belt and/or an appropriate child restraint system.
● 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.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.
■ Child restraint lock function belt precaution
Do not allow children to play with the child restraint lock function belt. If the
belt becomes twisted around a child’s neck, it will not be possible to pull the
belt out leading 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 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.

CAUTION
■Seat belt damage and wear
● 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 a seat
belt. Have any necessary repairs carried out by your Toyota dealer. Inap-
propriate handling of the pretensioner may cause it to activate or operate
improperly and may cause death or serious injury.
■ 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. 86)
■ 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.

the controls are easily oper-
able.

positions of the steering
wheel downward so the air-
bag is facing your chest.

CAUTION
■While driving
● Do not adjust the position of the driver’s seat. 
Doing so could cause the driver to lose control of the vehicle.
● Do not place a cushion between the driver or passenger and the seatback. 
A cushion may prevent correct posture from being achieved, and reduce
the effectiveness of the seat belt and head restraint, increasing the risk of
death or serious injury to the driver or passenger.
● Do not place anything under the front seats. 
Objects placed under the front seats may become jammed in the seat
tracks and stop the seat from locking in place. This may lead to an acci-
dent. The adjustment mechanism may also be damaged.
■ Adjusting the seat position
● Do 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 during an accident, the lap belt may slide part 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.
● Take care when adjusting the seat position to ensure that other passen-
gers are not injured by the moving seat.
● Do not put your hands under the seat or near the moving parts to avoid
injury. 
Fingers or hands may become jammed in the seat mechanism.
