1-2. Seat Belt Systems
WARNING
■Wear seat belts only as recommended in this owner’s manual
Incorrect positioning of the driver and front passenger seat be lts is danger-
ous. Without proper positioning, the pretensioner and load limi ting systems
cannot provide adequate protection in an accident and this coul d result in
serious injury. For more details about wearing seat belts, refe r to “Fastening
the seat belts” ( P. 34).
■ Have your seat belts changed immed iately if the pretensioner or load
limiter has been expended
Always have your Toyota dealer immediately inspect the seat bel t 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 b e 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 se at belt at all;
however, if the seat belt pretensioners and load limiters are n ot replaced,
the risk of injury in a collision will increase.
■ Do not modify the components or wiring, or use electronic testi ng
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 a ctivating in an
accident. The occupants or repairers could be seriously injured .
■ Properly dispose of the 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 veh icle.

Essential Safety Equipment
If your vehicle is also equipped with a front passenger occupant clas-
sification system, refer to the Front Passenger Occupant Classi fica-
tion System ( P. 78) for details.
If your vehicle is equipped with a
front passenger occupant classifi-
cation system, the front passen-
ger air bag deactivation indicator
light illuminates for a specified
time after the ignition is switched
ON.
Small children must be protected by a child-restraint system as stipu-
lated by law in every state and province. In certain states and prov-
inces, larger children must use a child-restraint system (P. 4 1 ) .
Carefully consider which child-re straint system is necessary for your
child and follow the installation directions in this Owner’s Manual as
well as the child-restraint syste m manufacturer’s instructions.
●If it becomes necessary to have the components or wiring system for the
supplementary restraint system modified to accommodate a person with
certain medical conditions in accordance with a certified physi cian, contact
your Toyota dealer.
● When an air bag deploys, a loud inflation noise can be heard an d some
smoke will be released. Neither is likely to cause injury, howe ver, the texture
of the air bags may cause light skin injuries on body parts not covered with
clothing through friction.
● Should you sell your Toyota, we urge you to tell the new owner of its air bag
systems and that familiarization with all instructions about th em, from the
Owner’s Manual, is important.
● This highly-visible label is displayed
which warns against the use of a rear-
facing child-restraint system on the front
passenger seat.

WARNING
■Do not modify a front door or l eave any damage unrepaired. Always
have your Toyota dealer ins pect a damaged front door
Modifying a front door or leaving any damage unrepaired is dang erous.
Each front door has a side crash sensor as a component of the s upplemen-
tal restraint system. If holes are drilled in a front door, a door speaker is left
removed, or a damaged door is left unrepaired, the sensor could be
adversely affected causing it to not detect the pressure of an impact cor-
rectly during a side collision. If a sensor does not detect a s ide impact cor-
rectly, the side and curtain air bags and the front seat belt pretensioner may
not operate normally which could result in serious injury to oc cupants.
■ Do not modify the supplemental restraint system
Modifying the components or wiring of the supplemental restrain t system is
dangerous. You could accidentally activate it or make it inoper able. Do not
make any modifications to the supplemental restraint system. Th is includes
installing trim, badges, or anything else over the air bag modu les. It also
includes installing extra electrical equipment on or near syste m components
or wiring. Your Toyota dealer can provide the special care need ed in the
removal and installation of front seats. It is important to pro tect the air bag
wiring and connections to assure that the bags do not accidenta lly deploy,
and that the front passenger occupant classification system and the seats
retain an undamaged air bag connection.
■ Do not place luggage or other objects under the front seats
Placing luggage or other objects under the front seats is dange rous. The
components essential to the supplemental restraint system could be dam-
aged, and in the event of a side collision, the appropriate air bags may not
deploy, which could result in death or serious injury. To preve nt damage to
the components essential to the supplemental restraint system, do not
place luggage or other objects under the front seats.
■ Do not operate a vehicle with damaged air bag/seat belt pretens ioner
system components
Expended or damaged air bag/seat belt pretensioner system components
must be replaced after any collision which caused them to deplo y or dam-
age them. Only a trained Authorized Toyota Dealer can fully eva luate these
systems to see that they will work in any subsequent accident. Driving with
an expended or damaged air bag or pretensioner unit will not afford you the
necessary protection in the event of any subsequent accident wh ich could
result in serious injury or death.

Constant Monitoring
The following components of the air bag systems are monitored by a
diagnostic system: • Crash sensors, and diagnostic module (SAS unit)
• Front air bag sensors
• Air bag modules
• Side crash sensors
• Air bag/Front seat belt pret ensioner system warning light
• Front seat belt pretensioners
• Related wiring
• Front passenger air bag d eactivation indicator light
• Front passenger occupant classification sensor
• Front passenger occupant classification module
The diagnostic module continuously monitors the system’s readin ess.
This begins when the ignition is switched ON and continues whil e the
vehicle is being driven.
