Seat belts
Make sure that all occupants
are wearing their seat belts
before driving the vehicle.
WARNING
Observe the following precautions to
reduce the risk of injury in the event of sudden braking, sudden swerving or an accident.
Failure 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
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 posi-tion, 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.
■Pregnant women
Obtain medical advice and wear the seat belt in the proper way. ( →P. 3 4 )
Women who are pregnant should position the lap belt as low as possi-ble over the hips in the same manner
as other occupants, extending the shoulder belt completely over the shoulder and avoiding belt contact
with the rounding of the abdominal area.
If the seat belt is not worn properly,
not only the pregnant woman, but also the fetus could suffer death or serious injury as a result of sudden
braking or a collision.
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( →P. 3 4 )
■When children are in the vehicle
→ P. 6 2
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate, or buckle to
be jammed in the door.

2To release the seat belt, press
the release button .
■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.
When the seat belt locks, pull the belt strongly and then release the belt, then a slow and easy pulling will allow the
belt to extend.
■After using the rear center seat belt
Stow seat belt buckle in the pocket.
The pretensioners help the seat
belts to quickly restrain the occu-
pants by retracting the seat belts
when the vehicle is subjected to
certain types of severe frontal or
side collision.
The pretensioners do not activate in the
event of a minor frontal impact, a minor
side impact, a rear impact or a vehicle
rollover.
■Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple colli-
sions, the pretensioner will activate for the first collision, but will not activate for the second or subsequent collisions.
■PCS-linked seat belt pretensioner
control (vehicles with Toyota Safety Sense)
If the PCS (Pre-Collision System) deter-
mines that the possibility of a collision with a vehicle is high, the seat belt pretensioners will be prepared to oper-
ate.
Seat belt pretensioners
(front and outboard rear
seats)
WARNING
■Seat belt pretensioners
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 any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer. Failure to do so may cause death or serious injury.
