Essential Safety Equipment
When the seat belt is fastened, it will always be in the emergency
locking mode.
In the emergency locking mode, the belt remains comfortable on the
occupant and the retractor will lock in position during a collision.
If the belt is locked and cannot be pulled out, retract the belt once, and
then try pulling it out slowly. If this fails, pull the belt strongly one time
and loosen, then pull it out again slowly.
Seat Belt with Automatic Locking Mode:
When the seat belt is fa stened, it will always be in the emergency
locking mode until it is switched to automatic locking mode by pulling
it all the way out to its full length . If the belt feels tight and hinders
comfortable movement while the vehicle is stopped or in motion, it
may be in the automatic locking mode because the belt has been
pulled too far out. To return the belt to the more comfortable emer-
gency locking mode, wait until the ve hicle has stopped in a safe, level
area, retract the belt fully to convert it back to emergency locking
mode and then extend it around you again.
Always use the automatic locking mode to keep the child-restraint
system from shifting to an unsafe pos ition in the event of an accident.
To enable seat belt automatic locking mode, pull it all the way out and
connect it as instructed on the chil d-restraint system. It will retract
down to the child-restrai nt system and stay locked on it. See the sec-
tion on child restraint ( →P. 41).

Seat Belt
Position the lap belt as low as
possible, not on the abdominal
area, then adjust the shoulder belt
so that it fits snugly against your
body.
Depress the button on the seat
belt buckle. If the belt does not
fully retract, pull it out and check
for kinks or twists. Then make
sure it remains untwisted as it
retracts.
If a belt does not fully retract, inspect it for kinks and twists. If it is still not
retracting properly, have it inspected at your Toyota dealer.

Seat Belt Pretensioner and Load Limiting
Systems
◆Pretensioners
When a collision is dete cted, the pretensioners deploy simultane-
ously with the air bags.
The pretensioners deploy simultan eously with the air bags when a
roll-over is also detected.
For deployment details, refer to the SRS Air Bag Deployment Crite-
ria ( →P. 74).
The front seat belt retractors remove slack quickly as the air bags
are expanding. Any time the air ba gs and seat belt pretensioners
have fired they must be replaced.
A system malfunction or operation conditions are indicated by a
warning.
Refer to Warning/Indicator Lights on P. 156.
Refer to Air Bag/Front Seat Belt Pretensioner System Warning
Beep on P. 514.
In addition, the pretensioner syst em for the front passenger, like the
front and side passenger air bag, is designed to only deploy when
the front passenger occupant clas sification sensor detects a pas-
senger sitting on the front passenger’s seat.
For details, refer to the front passenger occupant classification sen-
sor ( →P. 7 8 ) .
For optimum protection, the driver and front passenger seat
belts are equipped with pretensi oner and load limiting systems.
For both these systems to work properly you must wear the seat
belt properly.

◆Load limiter
The load limiting system releases belt webbing in a controlled man-
ner to reduce belt force on the occupant’s chest. While the most
severe load on a seat belt occurs in frontal collisions, the load lim-
iter has an automatic mechanical fu nction and can activate in any
accident mode with suff icient occupant movement.
Even if the pretensioners have not fired, the load limiting function
must be checked by your Toyota dealer.
● The pretensioner system may not operate depending on the type of the col-
lision. For details, refer to the SRS Air Bag Deployment Criteria ( →P. 74)
● Some smoke (non-toxic gas) will be released when the air bags and preten-
sioners deploy. This does not indicate a fire. This gas normally has no effect
on occupants, however, those with sensitive skin may experience light skin
irritation. If residue from the deployment of the air bags or the front preten-
sioner system gets on the skin or in the eyes, wash it off as soon as possi-
ble.

WARNING
■Wear seat belts only as recommended in this owner’s manual
Incorrect positioning of the driver and front passenger seat belts is danger-
ous. Without proper positioning, the pretensioner and load limiting systems
cannot provide adequate protection in an accident and this could result in
serious injury. For more details about wearing seat belts, refer to “Fastening
the seat belts” (→P. 34).
■ Have your seat belts changed immediately if the pretensioner or load
limiter has been expended
Always have your Toyota dealer immediately inspect the seat belt preten-
sioners and air bags after any collision. Like the air bags, the seat belt pre-
tensioners and load limiters will only function once and must be replaced
after any collision that caused them to deploy. A seat belt with an expended
pretensioner or load limiter is still better than wearing no seat belt at all;
however, if the seat belt pretensioners and load limiters are not replaced,
the risk of injury in a collision will increase.
■ Do not modify the components or wiring, or use electronic testing
devices on the pretensioner system
Modifying the components or wiring of the pretensioner system, including
the use of electronic testing devices is dangerous. You could accidentally
activate it or make it inoperable which would prevent it from activating in an
accident. The occupants or repairers could be seriously injured.
■ Properly dispose of th e pretensioner system
Improper disposal of the pretensioner system or a vehicle with non-deacti-
vated pretensioners is dangerous. Unless all safety procedures are fol-
lowed, injury could result. Have your Toyota dealer safely dispose of the
pretensioner system or scrap a pretensioner system equipped vehicle.

Essential Safety Equipment
Seat Belt Extender
This extender will be only for you and for the particular vehicle and
seat. Even if it plugs into other seat belts, it may not hold in the critical
moment of a crash.
When ordering an extender, only order one that provides the neces-
sary additional length to fa sten the seat belt properly.
Please contact your Toyota dealer for more information.
When not in use, remove the seat belt extender and store it in the vehicle. If
the seat belt extender is left connected, the seat belt extender might get dam-
aged as it will not retract with the rest of the seat belt and can easily fall out of
the door when not in use and be damaged. In addition, the seat belt warning
light will not illuminate and function properly.
If your seat belt is not long enough, even when fully extended, a
seat belt extender may be available to you at no charge from
your Toyota dealer.
WARNING
■ Do not use a seat belt ext ender unless it is necessary
Using a seat belt extender when not necessary is dangerous. The seat belt
will be too long and not fit properly. In an accident, the seat belt will not pro-
vide adequate protection and you could be seriously injured. Only use the
extender when it is required to fasten the seat belt properly.
■ Do not use an improper extender
Using a seat belt extender that is for another person or a different vehicle or
seat is dangerous. The seat belt will not provide adequate protection and
the user could be seriously injured in an accident. Only use the extender
provided for you and for the particular vehicle and seat. NEVER use the
extender in a different vehicle or seat. If you sell your Toyota, do not leave
your seat belt extender in the vehicle. It could be used accidentally by the
new owner of the vehicle. After removing the seat belt extender, discard it.
Never use the seat belt extender in any other vehicle you may own in the
future.

WARNING
■Do not use an extender that is too long
Using an extender that is too long is dangerous. The seat belt will not fit
properly. In an accident, the seat belt will not provide adequate protection
and you could be seriously injured. Do not use the extender or choose one
shorter in length if the distance between the extender’s buckle and the cen-
ter of the user’s body is less than 6 in. (150 mm).
■ Do not leave a seat belt exte nder connected to the buckle
Leaving a seat belt extender connected to the buckle without using the seat
belt is dangerous. When the seat belt extender is connected to the driver’s
seat belt buckle (or front passenger’s seat belt buckle), the SRS driver’s (or
front passenger’s) air bag system will determine that the driver (or front pas-
senger) is wearing the seat belt even if the driver (or front passenger) is not
wearing it. This condition could cause the driver’s (or front passenger’s) air
bag to not activate correctly and result in death or serious injury in the event
of collision. Always wear the seat belt with the seat belt extender.
■ Do not use the seat belt extender when installing a child-restraint sys-
tem on the front or rear passenger seat
Using a seat belt extender to fasten a child-restraint system on any seat is
dangerous. Always follow the child-restraint system manufacturer’s installa-
tion instructions and never use a seat belt extender.
