Your vehicle is equipped with SMART AIR BAGS designed to US Motor Vehicle Safety Standards (FMVSS208). The airbag sensor assembly (ECU) regulates airbag deployment based on the information it receives from sensors, etc., shown above in the system component diagram. This information includes the severity of the impact and the occupancy of the vehicle by the passengers. The rapid deployment of the airbags is achieved by means of a chemical reaction in the pyrotechnic devices, which produces a harmless gas which helps to dampen the movement of the occupants.

WARNING

SRS airbag precautions

  • Observe the following precautions regarding the SRS airbags. Failure to follow these precautions could result in serious injury or even death.
  • The driver and all passengers in the vehicle must wear their seat belts correctly. SRS airbags are supplemental devices for use with seat belts.
  • The SRS driver’s airbag inflates with considerable force, which could cause serious injury or death if the driver is in close proximity to the airbag.
  • The US Federal Highway Traffic Safety Authority (NHTSA) advises:
  • The driver airbag hazard zone within the first 2 to 3 in. (50 to 75 mm) of deployment, position yourself 10 in. (250 mm) of your driver’s airbag guarantees you a sufficient safety margin.
  • This distance is to be measured between the center of the steering wheel and the sternum.
  • If you are seated less than 10 in. (250 mm), you can change your driving position in several ways:
  • Move your seat as far back as possible, so that you can still comfortably reach the pedals.
  • Tilt the seat back slightly. Although the vehicles have different designs, a large number of drivers can sit at a distance of 10 in. (250 mm), even with the driver’s seat fully forward, simply by tilting the seat back a little.
  • If you have difficulty seeing the road after reclining the back of your seat, use a firm, non-slip cushion to raise yourself up or raise the seat if your vehicle has this feature.
  •  If your steering wheel is adjustable, tilt it down.
  • This has the effect of directing the airbag towards your chest rather than your head and neck.
  • Adjust your seat according to the NHTSA recommendations above, while maintaining control of the pedals, steering wheel, and view of the dashboard controls
WARNING

SRS airbag precautions

  • If you attach a seat belt extender to the driver’s seat belt buckle without attaching it to the driver’s seat belt latch, the driver’s SRS frontal airbags determine that the driver has fastened the seat belt correctly. the seat belt is not fastened.
  • In this case, the driver’s SRS front airbags may not deploy properly in the event of a collision, which could result in serious injury or death.Toyota BZ4X 2023 For owners (4)
  • Be sure to wear the seat belt with the seat belt extender.
  • The SRS front passenger air bag also inflates with considerable force, which could cause serious injury or death if the front passenger is very close to the air bag.
  • The front passenger seat should be positioned as far away from the air bag as possible by adjusting the seatback so that the front passenger sits upright in the seat.
  • Infants and children who are not properly seated and/or restrained can be seriously injured or killed by an inflating air bag.
  • An infant or child too small to use a seat belt must be properly restrained in a child safety seat.
  • Toyota strongly recommends placing all infants and children in the rear seats of the vehicle and providing suitable restraint systems for them.
  • The rear seats are safer for infants and children than the front passenger seat.
  • Never install a rear-facing type child safety seat on the front passenger seat, even if the “AIR BAG OFF” indicator light is on.
  • In the event of an accident, the force generated by the rapid deployment of the front passenger airbag can seriously injure or even kill the child if the rear-facing child safety seat is installed on the front passenger seat.
WARNING

SRS airbag precautions

  • Do not sit on the edge of the seat or lean against the dashboard.Toyota BZ4X 2023 For owners (5)
  • Do not let a child stand in front of the SRS front passenger airbag or sit on the front passenger’s lap.
  • Do not allow front seat occupants to travel with an object on their lap.Toyota BZ4X 2023 For owners (6)
    • Do not lean against the door, roof side rail or front, side and rear pillars.Toyota BZ4X 2023 For owners (7)
  • Do not allow anyone to kneel on the passenger seats leaning against the door or extend their head or hands outside the vehicle.Toyota BZ4X 2023 For owners 8)

 

WARNING

SRS airbag precautions

  • Do not attach or place anything on places such as the dashboard, steering wheel trim and the lower part of the dashboard.Toyota BZ4X 2023 For owners (9)
  • These items can become projectiles when the SRS driver, front passenger, and knee airbags deploy.Toyota BZ4X 2023 For owners (10)

 

  • Do not attach anything to the doors, windshield, windows, front and rear pillars, roof side rail and grab handle.
  • Do not hang hangers or hard objects on the coat hooks. Any of these objects could become projectiles and cause serious injury or death if the SRS curtain airbags inflate.
WARNING

SRS airbag precautions

  • If a vinyl cover is placed over the area where the SRS knee airbag inflates, be sure to remove it.
  • Do not use any seat accessory that covers the deployment areas of the SRS side airbags, as they may interfere with the deployment of the SRS airbags. Such accessories could prevent the side airbags from working properly, disable the system or cause the side airbags to inflate accidentally, resulting in death or serious injury.
  • Avoid applying excessive pressure or impact to parts containing SRS airbag components or front doors. This could cause the SRS airbags to malfunction.
  • Do not touch any components immediately after the SRS airbags deploy (inflate) as they may be hot.
  • If you have difficulty breathing after the SRS airbags inflate, open a door or window to bring in fresh air, or get out of the vehicle if it is safe to do so. Wipe off any residue as soon as possible to avoid possible skin irritation.
  • If the parts containing the SRS airbags, such as the trim on the steering wheel and the front and rear pillars, are damaged or cracked, have them replaced by your Toyota dealer.
  • Do not place anything on the front passenger seat, such as a cushion. This has the effect of distributing the weight of the passenger over the entire surface of the seat, which prevents the sensor from correctly detecting the weight of the passenger. As a result, the front passenger’s SRS frontal airbags may not deploy in the event of a collision.
WARNING

Modification and disposal of SRS airbag system components

  • Do not scrap 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, removal and repair of SRS airbags
  • Repairs, modifications, removal or replacement of the steering wheel, dashboard, dashboard, seats or their upholstery, front, side and rear pillars, roof side rails, front door panels, front door trim or front door speakers
  • Modifications to the front door panel (for example, drilling a hole in the panel)
  • Repairs or modifications to the fender front, the front bumper or the sides of the passenger compartment
  • Installation of a grille guard (bull bar, kangaroo bar, etc.), snow plows, winches, or a luggage rack
  • Modifications to the vehicle’s suspension system
  • Installation of electronic devices such as mobile radio transmitters/receivers and CD players
  • Modifications to your vehicle for a person with a physical disability
