Toyota Sienna 2010-2024 Owners Manual: SRS airbags

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.

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.

WARNING

SRS airbag precautions

Observe the following precautions regarding the SRS airbags.

Failure to do so may cause death or serious injury.

  • The driver and all passengers in the vehicle must wear their seat belts properly.
  • he SRS airbags are supplemental devices to be used with the seat belts.
  • The SRS driver airbag deploys with considerable force, and can cause death or serious injury especially if the driver is very close to the airbag.

    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:

  • Move your seat to the rear as far as you can while still reaching the pedals comfortably.
  • Slightly recline the back of the seat.

    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.

  • If your steering wheel is adjustable, tilt it downward. This points the airbag toward your chest instead of your head and neck.

    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 Sienna. SRS airbag precautions


  • If the seat belt extender has been connected to the front seat belt buckles but the seat belt extender has not also been fastened to the latch plate of the seat belt, the SRS front airbags will judge that the driver and front passenger are wearing the seat belt even though the seat belt has not been connected. In this case, the SRS front airbags may not activate correctly in a collision, resulting in death or serious injury in the event of a collision. Be sure to wear the seat belt with the seat belt extender.
  • The SRS front passenger airbag also deploys with considerable force, and can cause death or serious injury especially if the front passenger is very close to the airbag. The front passenger seat should be as far from the airbag as possible with the seatback adjusted, so the front passenger sits upright.
  • Improperly seated and/or restrained infants and children can be killed or seriously injured by a deploying airbag. An infant or child who is too small to use a seat belt should be properly secured using a child restraint system.

    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.

SRS airbag precautions

  • Do not sit on the edge of the seat or lean against the dashboard.

  • Do not allow a child to stand in front of the SRS front passenger airbag unit or sit on the knees of a front passenger.
  • Do not allow the front seat occupants to hold items on their knees.

  • Do not lean against the door, the roof side rail or the front, side and rear pillars.

  • Do not allow anyone to kneel on the passenger seat toward the door or put their head or hands outside the vehicle

SRS airbag precautions

  • Do not attach anything to or lean anything against areas such as the dashboard, steering wheel pad and lower portion of the instrument panel.

    These items can become projectiles when the SRS driver, front passenger and driver’s knee airbags deploy.

  • Do not attach anything to areas such as a door, windshield glass, side door glass, front or rear pillar, roof side rail and assist grip.

Toyota Sienna. SRS airbag precautions


  • Vehicles without a smart key system: Do not attach any heavy, sharp or hard objects such as keys and accessories to the key. The objects may restrict the SRS knee airbag inflation or be thrust into the driver’s seat area by the force of the deploying airbag, thus causing a danger.

SRS airbag precautions

  • Do not hang coat hangers or other hard objects on the coat hooks. All of these items could become projectiles and may cause death or serious injury, should the SRS curtain shield airbags deploy.
  • If a vinyl cover is put on the area where the SRS knee airbag will deploy, be sure to remove it.
  • Do not use seat accessories which cover the parts where the SRS side airbags and SRS seat cushion airbag inflate as they may interfere with inflation of the SRS airbags. Such accessories may prevent the side airbags and seat cushion airbag from activating correctly, disable the system or cause the side airbags and seat cushion airbag to inflate accidentally, resulting in death or serious injury.
  • Do not strike or apply significant levels of force to the area of the SRS airbag components.

    Doing so can cause the SRS airbags to malfunction.

  • Do not touch any of the component parts immediately after the SRS airbags have deployed (inflated) as they may be hot.
  • If breathing becomes difficult after the SRS airbags have deployed, open a door or window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off any residue as soon as possible to prevent skin irritation.
  • If the areas where the SRS airbags are stored, such as the steering wheel pad and front and rear pillar garnishes, are damaged or cracked, have them replaced by your Toyota dealer.
  • Do not place anything, such as a cushion, on the front passenger’s seat.

    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

  • Do not dispose of your vehicle or perform any of the following modifications without consulting your Toyota dealer.

    The SRS airbags may malfunction or deploy (inflate) accidentally, causing death or serious injury.

  • Installation, removal, disassembly and repair of the SRS airbags
  • Repairs, modifications, removal or replacement of the steering wheel, instrument panel, dashboard, seats or seat upholstery, front, side and rear pillars or roof side rails
  • Repairs or modifications of the front fender, front bumper, or side of the occupant compartment
  • Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows, winches or roof luggage carrier
  • Modifications to the vehicle’s suspension system
  • Installation of electronic devices such as mobile two-way radios and CD players
  • Modifications to your vehicle for a person with a physical disability

If the SRS airbags deploy (inflate)

SRS airbag deployment conditions (SRS front airbags)

However, this threshold velocity will be considerably higher in the following situations:

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 and 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.

Types of collisions that may not deploy the SRS airbag (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.

Toyota Sienna. Types of collisions that may not deploy the SRS airbags


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 collision or low-speed frontal collision.

Toyota Sienna. Types of collisions that may not deploy the SRS airbags


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.
