1-4. SRS Air Bags  
Supplemental Restraint System (SRS) Pre-  
cautions  
The front and side supplemental restraint systems (SRS) include dif-  
ferent types of air bags. Please verify the different types of air bags  
which are equipped on your vehicle by locating the “SRS AIRBAG”  
location indicators. These indicators are visible in the area where the  
air bags are installed.  
The air bags are installed in the following locations:  
• The steering wheel hub (driver air bag)  
• The front passenger dashboard (front passenger air bag)  
• The outboard sides of the front seatbacks (side air bags)  
• The front and rear window pillars, and the roof edge along both  
sides (curtain air bags)  
Vehicles with the Front Passenger Occupant Classification System  
have a sensor which detects an impending roll-over accident.  
The air bag supplemental restraint systems are designed to provide  
supplemental protection in certain situations so seat belts are always  
important in the following ways:  
Without seat belt usage, the air bags cannot provide adequate protec-  
tion during an accident. Seat belt usage is necessary to:  
• Keep the occupant from being thrown into an inflating air bag.  
• Reduce the possibility of injuries during an accident that is not  
designed for air bag inflation, such as rear impact.  
• Reduce the possibility of injuries in frontal, near frontal or side colli-  
sions or roll-over accidents that are not severe enough to activate  
the air bags.  
• Reduce the possibility of being thrown from your vehicle.  
• Reduce the possibility of injuries to lower body and legs during an  
accident because the air bags provide no protection to these parts  
of the body.  
• Hold the driver in a position which allows better control of the vehi-  
cle.

If your vehicle is also equipped with a front passenger occupant clas-  
sification system, refer to the Front Passenger Occupant Classifica-  
tion System (P. 82) 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. 44).  
Carefully consider which child-restraint system is necessary for your  
child and follow the installation directions in this Owner’s Manual as  
well as the child-restraint system 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 physician, contact  
your Toyota dealer.  
When an air bag deploys, a loud inflation noise can be heard and some  
smoke will be released. Neither is likely to cause injury, however, 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 them, 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.

1-4. SRS Air Bags  
WARNING  
Seat belts must be worn in air bag equipped vehicles  
Depending only on the air bags for protection during an accident is danger-  
ous. Alone, air bags may not prevent serious injuries. The appropriate air  
bags can be expected to inflate only in the first accident, such as frontal,  
near frontal or side collisions or roll-over accidents that are at least moder-  
ate. Vehicle occupants should always wear seat belts.  
Children should not ride in the front passenger seat  
Placing a child, 12 years or under, in the front seat is dangerous. The child  
could be hit by a deploying air bag and be seriously injured or even killed. A  
sleeping child is more likely to lean against the door and be hit by the side  
air bag in moderate collision to the front-passenger side of the vehicle.  
Whenever possible, always secure a child 12 years and under on the rear  
seats with an appropriate child-restraint system for the child’s age and size.  
Never use a rear-facing child-restraint system in the front seat with an  
air bag that could deploy  
Rear-facing child-restraint systems on  
the front seat are particularly dangerous  
even though you may feel assured that a  
front passenger air bag will not deploy  
based on the fact that the front passen-  
ger air bag deactivation indicator light  
illuminates. The child-restraint system  
can be hit by a deploying air bag and  
moved violently backward resulting in  
serious injury or death to the child.  
Do not sit too close to the driver and front passenger air bags  
Sitting too close to the driver and front passenger air bag modules or plac-  
ing hands or feet on them is extremely dangerous. The driver and front pas-  
senger air bags inflate with great force and speed. Serious injuries could  
occur if someone is too close. The driver should always hold onto only the  
rim of the steering wheel. The front seat passenger should keep both feet  
on the floor. Front seat occupants should adjust their seats as far back as  
possible and always sit upright against the seatbacks with seat belts worn  
properly.

1-4. SRS Air Bags  
WARNING  
Sit in the center of the seat and wear seat belts properly  
Sitting too close to the side air bag modules or placing hands on them, or  
sleeping up against the door or hanging out the windows is extremely dan-  
gerous. The side and curtain air bags inflate with great force and speed  
directly expanding along the door on the side the car is hit. Serious injury  
could occur if someone is sitting too close to the door or leaning against a  
window, or if rear seat occupants grab the sides of the front seatbacks. Give  
the side and curtain air bags room to work by sitting in the center of the seat  
while the vehicle is moving with seat belts worn properly.  
1
Do not attach objects on or around the area where driver and front pas-  
senger air bags deploy  
Attaching an object to the driver and front passenger air bag modules or  
placing something in front of them is dangerous. In an accident, an object  
could interfere with air bag inflation and injure the occupants.  
Do not attach objects on or around the area where a side air bag  
deploys  
Attaching objects to the front seat in such a way as to cover the outboard  
side of the seat in any way is dangerous. In an accident the object could  
interfere with the side air bag, which inflates from the outboard side of the  
front seats, impeding the added protection of the side air bag system or  
redirecting the air bag in a way that is dangerous. Furthermore, the bag  
could be cut open releasing the gas.  
Do not hang net bags, map pouches, backpacks with side straps or any  
other objects on the front seats. Never use seat covers on the front seats.  
Always keep the side air bag modules in your front seats free to deploy in  
the event of a side collision.  
Do not attach objects on or around the area where a curtain air bag  
deploys  
Attaching objects to the areas where the curtain air bag activates such as  
on the windshield glass, side door glass, front and rear window pillars and  
along the roof edge and assist grips is dangerous. In an accident the object  
could interfere with the curtain air bag, which inflates from the front and rear  
window pillars and along the roof edge, impeding the added protection of  
the curtain air bag system or redirecting the air bag in a way that is danger-  
ous. Furthermore, the bag could be cut open releasing the gas.  
Do not place hangers or any other objects on the assist grips. When hang-  
ing clothes, hang them on the coat hook directly. Always keep the curtain air  
bag modules free to deploy in the event of a side collision or roll-over acci-  
dent.

1-4. SRS Air Bags  
WARNING  
Do not touch the components of the supplemental restraint system  
after the air bags have inflated  
Touching the components of the supplemental restraint system after the air  
bags have inflated is dangerous. Immediately after inflation, they are very  
hot. You could get burned.  
Never install any front-end equipment to your vehicle  
Installation of front-end equipment, such as frontal protection bar (kangaroo  
bar, bull bar, push bar, or other similar devices), snowplow, or winches, is  
dangerous. The air bag crash sensor system could be affected. This could  
cause air bags to inflate unexpectedly, or it could prevent the air bags from  
inflating during an accident. Front occupants could be seriously injured.  
Do not modify the suspension  
Modifying the vehicle suspension is dangerous. If the vehicle’s height or the  
suspension is modified, the vehicle will be unable to accurately detect a col-  
lision or roll-over accident resulting in incorrect or unexpected air bag  
deployment and the possibility of serious injuries.  
To prevent false detection by the air bag sensor system, heed the fol-  
lowing  
Do not use tires or wheels other than those specified for your Toyota:  
Use of any tire or wheel other than those specified for your Toyota (P. 553)  
is dangerous. Use of such wheels will prevent the vehicle’s accident detec-  
tions system from accurately detecting a collision or roll-over accident result-  
ing in incorrect or unexpected air bag deployment and the possibility of  
serious injuries.  
Do not overload your vehicle:  
Overloading your vehicle is dangerous as it could prevent the air bag  
crash sensor system from accurately detecting a collision or roll-over acci-  
dent resulting in incorrect or unexpected air bag deployment and the pos-  
sibility of serious injuries. The gross axle weight rating (GAWR) and the  
gross vehicle weight rating (GVWR) for your vehicle are on the Motor  
Vehicle Safety Standard Label on the driver’s door frame. Do not exceed  
these ratings.  
Do not drive the vehicle off-road:  
Driving your Toyota off-road is dangerous because the vehicle has not  
been designed to do so. Driving the vehicle off-road could prevent the air  
bag crash sensor system from accurately detecting a collision or roll-over  
accident resulting in incorrect or unexpected air bag deployment and the  
possibility of serious injuries.

WARNING  
Do not modify a front door or leave any damage unrepaired. Always  
have your Toyota dealer inspect a damaged front door  
Modifying a front door or leaving any damage unrepaired is dangerous.  
Each front door has a side crash sensor as a component of the supplemen-  
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 side 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 occupants.  
1
Do not modify the supplemental restraint system  
Modifying the components or wiring of the supplemental restraint system is  
dangerous. You could accidentally activate it or make it inoperable. Do not  
make any modifications to the supplemental restraint system. This includes  
installing trim, badges, or anything else over the air bag modules. It also  
includes installing extra electrical equipment on or near system components  
or wiring. Your Toyota dealer can provide the special care needed in the  
removal and installation of front seats. It is important to protect the air bag  
wiring and connections to assure that the bags do not accidentally 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 dangerous. 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 prevent 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 pretensioner  
system components  
Expended or damaged air bag/seat belt pretensioner system components  
must be replaced after any collision which caused them to deploy or dam-  
age them. Only a trained Authorized Toyota Dealer can fully evaluate 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 which could  
result in serious injury or death.

WARNING  
Do not remove interior air bag parts  
Removing any components such as the front seats, front dashboard, the  
steering wheel or parts on the front and rear window pillars and along the  
roof edge, containing air bag parts or sensors is dangerous. These parts  
contain essential air bag components. The air bag could accidentally acti-  
vate and cause serious injuries. Always have your Toyota dealer remove  
these parts.  
Properly dispose of the air bag system  
Improper disposal of an air bag or a vehicle with live air bags in it can be  
extremely dangerous. Unless all safety procedures are followed, injury  
could result. Have your Toyota dealer safely dispose of the air bag system  
or scrap an air bag equipped vehicle.

How the SRS Air Bags Work  
Your Toyota is equipped with the following types of SRS air  
bags. SRS air bags are designed to work together with the seat  
belts to help to reduce injuries during an accident. The SRS air  
bags are designed to provide further protection for passengers  
in addition to the seat belt functions. Be sure to wear seat belts  
properly.  
Front Seat Belt Pretensioners  
The front seat belt pretensioners are designed to deploy in moder-  
ate or severe frontal, near frontal collisions.  
In addition, the pretensioners operate when a side collision or a roll-  
over accident is detected. The pretensioners operate differently  
depending on what types of air bags are equipped. For more details  
about the seat belt pretensioner operation, refer to the SRS Air Bag  
Deployment Criteria (P. 78).  
Driver Air Bag  
The driver’s air bag is mounted in the steering wheel.  
When air bag crash sensors  
detect  
a
frontal impact of  
greater than moderate force,  
the driver’s air bag inflates  
quickly helping to reduce injury  
mainly to the driver’s head or  
chest caused by directly hitting  
the steering wheel.  
For more details about air bag deployment, refer to “SRS Air Bag  
Deployment Criteria” (P. 78).  
The driver’s dual-stage air bag controls air bag inflation in two  
energy stages. During an impact of moderate severity, the driver’s  
air bag deploys with lesser energy, whereas during more severe  
impacts, it deploys with more energy.

1-4. SRS Air Bags  
Front Passenger Air Bag  
The front passenger air bag is mounted in the front passenger  
dashboard.  
The inflation mechanism for the  
front passenger air bag is the  
same as the driver’s air bag, as  
mentioned above.  
1
For more details about air bag  
deployment, refer to “SRS Air  
Bag Deployment Criteria”  
(P. 78).  
In addition, the front passenger air bag is designed to only deploy in  
accordance with the total seated weight on the front passenger  
seat. For details, refer to the front passenger occupant classifica-  
tion system (P. 82).  
Side Air Bags  
The side air bags are mounted in the outboard sides of the front  
seatbacks.  
When the air bag crash sensors  
detect a side impact of greater  
than moderate force, the sys-  
tem inflates the side air bag  
only on the side in which the  
vehicle was hit. The side air  
bag inflates quickly to reduce  
injury to the driver or front pas-  
senger’s chest caused by  
directly hitting interior parts  
such as a door or window.  
For more details about air bag deployment, refer to “SRS Air Bag  
Deployment Criteria” (P. 78).  
In addition, the front passenger side air bag is designed to only  
deploy when the front passenger occupant classification sensor  
detects a passenger sitting on the front passenger’s seat. For  
details, refer to the front passenger occupant classification system  
(P. 82).

1-4. SRS Air Bags  
Curtain Air Bags  
The curtain air bags are mounted in the front and rear window pil-  
lars, and the roof edge along both sides.  
When the air bag crash sensors detect a side impact of greater  
than moderate force, the curtain air bag inflates quickly and helps to  
reduce injury mainly to the rear outboard passenger’s head caused  
by directly hitting interior parts such as a door or window.  
For more details about air bag deployment, refer to “SRS Air Bag  
Deployment Criteria” (P. 78).  
In a side impact  
Greater than moderate impact to one side of the vehicle will cause  
the curtain air bag on that side only to inflate.  
Only one side curtain air bag  
will deploy on the side of the  
vehicle that receives the force  
of an impact.  
In a roll-over  
In response to a vehicle roll-over, both curtain air bags inflate.  
Both curtain air bags will deploy  
after the roll-over accident is  
detected.

Front Passenger Occupant Classification  
System  
First, please read “Supplemental Restraint System (SRS) Pre-  
cautions” (P. 66) carefully.  
Front Passenger Occupant Classification Sensor  
Your vehicle is equipped with a front passenger occupant classifica-  
tion sensor as a part of the supplemental restraint system. This sen-  
sor is equipped in the front passenger’s seat cushion. This sensor  
measures the electrostatic capacity of the front passenger’s seat. The  
SAS unit is designed to prevent the front passenger front and side air  
bags and seat belt pretensioner system from deploying if the front  
passenger air bag deactivation indicator light turns on.  
To reduce the chance of injuries caused by deployment of the front  
passenger air bag, the system deactivates the front passenger front  
and side air bags and also the seat belt pretensioner system when the  
front passenger air bag deactivation indicator light turns on. Refer to  
the following table for the front passenger air bag deactivation indica-  
tor light illumination conditions.  
This system shuts off the front passenger front and side air bags and  
seat belt pretensioner system, so make sure the front passenger air  
bag deactivation indicator light turns on according to the following  
table.  
The air bag/front seat belt pretensioner system warning light flashes  
and the front passenger air bag deactivation indicator light illuminates  
if the sensors have a possible malfunction. If this happens, the front  
passenger front and side air bags and seat belt pretensioner system  
will not deploy.

If the front passenger air bag deactivation indicator light does not  
turn on when the ignition is switched ON and does not turn on as  
indicated in the front passenger air bag deactivation indicator light  
on/off condition chart, do not allow an occupant to sit in the front  
passenger seat and consult your Toyota dealer as soon as possi-  
ble. The system may not work properly in an accident.  
The system requires about 10 seconds to alternate between turning the  
front passenger front and side air bags and seat belt pretensioner system on  
or off.  
The front passenger air bag deactivation indicator light may turn on repeat-  
edly if luggage or other items are put on the front passenger seat, or if the  
temperature of the vehicle’s interior changes suddenly.  
The front passenger air bag deactivation indicator light may turn on for 10  
seconds if the electrostatic capacity on the front passenger seat changes.  
The air bag/front seat belt pretensioner system warning light might turn on if  
the front passenger seat receives a severe impact.  
If the front passenger air bag deactivation indicator light does not turn on  
after installing a child-restraint system on the front passenger seat, first, re-  
install your child-restraint system according to the procedure in this owner’s  
manual. Then, if the front passenger air bag deactivation indicator light still  
does not turn on, install the child-restraint system on the rear seat and con-  
sult your Toyota dealer as soon as possible.  
If the front passenger air bag deactivation indicator light turns on when an  
occupant is seated directly in the front passenger seat, have the passenger  
re-adjust their posture by sitting with their feet on the floor, and then re-fas-  
tening the seat belt. If the front passenger air bag deactivation indicator light  
remains turned on, move the passenger to the rear seat. If sitting in the rear  
seat is not possible, slide the front passenger seat as far back as possible.  
Consult your Toyota dealer as soon as possible.

WARNING  
Do not allow an occupant in the front passenger’s seat to sit with a  
posture which makes it difficult for the front passenger occupant clas-  
sification sensor to detect the occupant correctly  
Sitting in the front passenger’s seat with a posture which makes it difficult  
for the front passenger occupant classification sensor to detect the occu-  
pant correctly is dangerous. If the front passenger occupant classification  
sensor cannot detect the occupant sitting on the front passenger’s seat cor-  
rectly, the front passenger front and side air bags and pretensioner system  
may not operate (deploy) or they may operate (deploy) accidentally. The  
front passenger will not have the supplementary protection of the air bags or  
the accidental operation (deployment) of the air bags could result in serious  
injury or death. Under the following conditions, the front passenger occu-  
pant classification sensor cannot detect a passenger sitting on the front  
passenger’s seat correctly and the deployment/non-deployment of the air  
bags cannot be controlled as indicated in the front passenger air bag deac-  
tivation indicator light on/off condition chart. For example:
