The srs airbags inflate when the vehicle is subjected to certain types of severe impacts that may cause significant injury to the occupants. They work together with the seat belts to help reduce the risk of death or serious injury.
Srs front airbags
Can help protect the head and chest of the driver and front passenger from impact with interior components
Can help provide driver protection
Can help restrain the front passenger
Srs side and curtain shield airbags
Can help protect the torso and hip of the front seat occupants
Srs airbag system components
Your vehicle is equipped with advanced airbags designed based on the us motor vehicle safety standards (fmvss208). The airbag sensor assembly (ecu) controls airbag deployment based on information obtained from the sensors etc. Shown in the system components diagram above. This information includes crash severity and occupant information. As the airbags deploy, a chemical reaction in the inflators quickly fills the airbags with non-toxic gas to help restrain the motion of the occupants.
Caution
Srs airbag precautions
Observe the following precautions regarding the srs airbags.
Failure to do so may cause death or serious injury.
The srs airbags are supplemental devices to be used with the seat belts.
The national highway traffic safety administration (nhtsa) advises: since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 Mm) of inflation, placing yourself 10 in. (250 Mm) from your driver airbag provides you with a clear margin of safety. This distance is measured from the center of the steering wheel to your breastbone. If you sit less than 10 in. (250 Mm) away now, you can change your driving position in several ways:
Although vehicle designs vary, many drivers can achieve the 10 in. (250 Mm) distance, even with the driver seat all the way forward, simply by reclining the back of the seat somewhat. If reclining the back of your seat makes it hard to see the road, raise yourself by using a firm, nonslippery cushion, or raise the seat if your vehicle has that feature.
The seat should be adjusted as recommended by nhtsa above, while still maintaining control of the foot pedals, steering wheel, and your view of the instrument panel controls.
Srs airbag precautions
Toyota strongly recommends that all infants and children be placed in the rear seats of the vehicle and properly restrained. The rear seats are safer for infants and children than the front passenger seat.
Caution
Srs airbag precautions
These items can become projectiles when the srs driver, front passenger and knee airbags deploy.
Srs airbag precautions
Doing so can cause the srs airbags to malfunction.
Srs airbag precautions
Doing so will disperse the passenger’s weight, which prevents the sensor from detecting the passenger’s weight properly. As a result, the srs front airbags for the front passenger may not deploy in the event of a collision.
Modification and disposal of srs airbag system components
If the srs airbags deploy (inflate)
Srs airbag deployment conditions (srs front airbags)
The srs front airbags will deploy in the event of an impact that exceeds the set threshold level (the level of force corresponding to an approximately 12 - 18 mph [20 - 30 km/h] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher in the following situations:
Depending on the type of collision, it is possible that only the seat belt pretensioners will activate.
The srs front airbags for the front passenger will not activate if there is no passenger sitting in the front passenger seat. However, the srs front airbags for the front passenger may deploy if luggage is put in the seat, even if the seat is unoccupied.
The srs seat cushion airbag on the front passenger’s seat will not operate if the occupant is not wearing a seat belt.
Srs airbag deployment conditions (srs side and curtain shield airbags)
Conditions under which the srs airbags may deploy (inflate), other than a collision
The srs front airbags, srs side and curtain shield airbags may also deploy if a serious impact occurs to the underside of your vehicle. Some examples are shown in the illustration.
The srs curtain shield airbags may also deploy under the situations shown in the illustration.
Types of collisions that may not deploy the srs airbags (srs front airbags)
The srs front airbags do not generally inflate if the vehicle is involved in a side or rear collision, if it rolls over, or if it is involved in a low-speed frontal collision. But, whenever a collision of any type causes sufficient forward deceleration of the vehicle, deployment of the srs front airbags may occur.
Types of collisions that may not deploy the srs airbags (srs side and curtain shield airbags)
The srs side and curtain shield airbags may not activate if the vehicle is subjected to a collision from the side at certain angles, or a collision to the side of the vehicle body other than the passenger compartment.
The srs side airbags do not generally inflate if the vehicle is involved in a rear collision, if it rolls over, or if it is involved in a low-speed side or lowspeed frontal collision.
The srs curtain shield airbags do not generally inflate if the vehicle is involved in a rear collision, if it pitches end over end, or if it is involved in a low-speed side or low-speed frontal collision.
When to contact your toyota dealer
In the following cases, the vehicle will require inspection and/or repair. Contact your toyota dealer as soon as possible.
Opening the fuel tank cap
