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.

• If the SRS airbags deploy (inflate) 
  • Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the extremely high-speed deployment (inflation) by hot gases.
  • A loud noise and white powder will be emitted.
  • Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as the front seats, parts of the front and rear pillars, and roof side rails, may be hot for several minutes. The airbag itself may also be hot.
  • The windshield may crack.
  • All of the doors will be unlocked. ( P.89)
  • Fuel supply to the engine will be stopped. ( P.294)
  • For Lexus Enform Safety Connect sub-scribers, if any of the following situations occur, the system is designed to send an emergency call to the response center, notifying them of the vehicle’s location (without needing to push the “SOS” but-ton) and an agent will attempt to speak with the occupants to ascertain the level of emergency and assistance required. If the occupants are unable to communicate, the agent automatically treats the call as an emergency and helps to dispatch the necessary emergency services.
    (P.52)
    An SRS airbag is deployed.
    A seat belt pre-tensioner is activated.
    The vehicle is involved in a sever rear-end collision.
• SRS airbag deployment conditions (SRS front airbags) 
  • SRS airbag deployment conditions (SRS front airbags)
    However, this threshold velocity will be considerably higher in the following situations:
    If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move or deform on impact
    If the vehicle is involved in an underride collision, such as a collision in which the front of the vehicle “underrides”, or goes under, the bed of a truck
  • Depending on the type of collision, it is possible that only the seat belt pretend-sinners 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.
• SRS airbag deployment conditions (SRS side and curtain shield airbags)
  • The SRS side and curtain shield airbags will deploy in the event of an impact that exceeds the set threshold level (the level of force corresponding to the impact force produced by an approximately 3300 lb. [1500 kg] vehicle colliding with the vehicle cabin from a direction perpendicular to the vehicle orientation at an approximate speed of 12 – 18 mph [20 – 30 km/h]).
  • Both SRS curtain shield airbags will deploy in the event of vehicle rollover.
  • All SRS side and curtain shield airbags will deploy in the event of a severe frontal collision.
• Conditions under which the SRS air-bags 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.
  • Hitting a curb, edge of pavement or hard surface
  • Falling into or jumping over a deep hole
  • Landing hard or falling
    The SRS curtain shield airbags may also deploy under the situations shown in the illustration.
  • The angle of vehicle tip-up is marginal.
  • The vehicle skids and hits a curb stone.
• 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.
  • Collision from the side
  • Collision from the rear
  • Vehicle rollover

Front passenger occupant classification system

Your vehicle is equipped with a front-passenger occupant classification system. This system detects the conditions of the front passenger seat and activates or deactivates the front passenger airbag and front passenger knee airbag.

System components

• A Driver’s and front passenger’s seat belt reminder light
• B SRS warning light
  For the U.S.A.
• C AIR BAG OFF” indicator light
• D AIR BAG ON” indicator light
  For Canada
• E AIR BAG OFF” indicator light
• F AIR BAG ON” indicator light

WARNING
Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant classification system.
Failure to do so may cause death or serious injury.

• Wear the seat belt properly.
• Make sure the front passenger’s seat belt plate has not been left inserted into the buckle before someone sits in the front passenger seat.
• Make sure the “AIR BAG OFF” indicator light is not illuminated when using the seat belt extender for the front passenger seat. If the “AIR BAG OFF” indicator light is illuminated, disconnect the extender tongue from the seat belt buckle, and reconnect the seat belt. Reconnect the seat belt extender after making sure the “AIR BAG ON” indicator light is illuminated. If you use the seat belt extender while the “AIR BAG OFF” indicator light is illumi-nated, the SRS airbags for the front passenger may not activate, which could cause death or serious injury in the event of a collision.
• Do not apply a heavy load to the front passenger seat or equipment (e.g. seatback pocket).
• Do not put weight on the front passenger seat by putting your hands or feet on the front passenger seat seatback from the rear passenger seat.
• Do not let a rear passenger lift the front passenger seat with their feet or press on the seatback with their legs.
• Do not put objects under the front passenger seat.
• Do not recline the front passenger seatback so far that it touches a rear seat. This may cause the “AIR BAG OFF” indicator light to be illuminated, which indicates that the SRS airbags for the front passenger will not activate in the event of a severe accident. If the seatback touches the rear seat, return the seatback to a position where it does not touch the rear seat. Keep the front passenger seatback as upright as possible when the vehicle is moving. Reclining the seatback excessively may lessen the effectiveness of the seat belt system.
• If an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illuminated. If the “AIR BAG OFF” indicator is illuminated, ask the passenger to sit up straight, well back in the seat, feet on the floor, and with the seat belt worn correctly. If the “AIR BAG OFF” indicator still remains illumi-nated, either ask the passenger to move to the rear seat, or if that is not possible, move the front passenger seat fully rearward.
• When it is unavoidable to install a forward-facing child restraint system on the front passenger seat, install the child restraint system on the front passenger seat in the proper order.
  ( P.41)
• Do not modify or remove the front seats.
• Do not kick the front passenger seat or subject it to severe impact. Otherwise, the SRS warning light may come on to indicate a malfunction of the front passenger occupant classification system. In this case, contact your Lexus dealer immediately.
• Child restraint systems installed on the rear seat should not contact the front seatbacks.
• Do not use a seat accessory, such as a cushion and seat cover, that covers the seat cushion surface.
• Do not modify or replace the upholstery of the front seat.
• Do not place anything between the console box and front passenger seat. Otherwise, the system may not detect the front passenger properly, leading to improper operation of the airbags.
• Adjust the front passenger seat so that the head restraint does not touch the ceiling. If the head restraint is left in contact with the ceiling, the system may not detect the front passenger properly, leading to improper operation of the airbags.

Riding with children
Observe the following precautions when children are in the vehicle. Use a child restraint system appropriate for the child, until the child becomes large enough to properly wear the vehicle’s seat belt.

• It is recommended that children sit in the rear seats to avoid accidental contact with the shift lever, wiper switch, etc.
• Use the window lock switch to avoid children operating the power window accidentally. (P.113)
• Do not let small children operate equipment that may catch or pinch body parts, such as the power window, hood, trunk, seats etc.
