Lexus NX: 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.

■ Location of the SRS airbags

Lexus NX. For safe use

SRS front airbags

  1. SRS driver airbag/front passenger airbag
    Can help protect the head and chest of the driver and front passenger from impact with interior components
  2. SRS knee airbag
    Can help provide driver protection
  3. SRS seat cushion airbag
    Can help restrain the front passenger

SRS side and curtain shield airbags

  1. SRS side airbags
    Can help protect the torso of the front seat occupants
  2. SRS curtain shield airbags
    • Can help protect primarily the head of occupants in the outer seats
    • Can help prevent the occupants from being thrown from the vehicle in the event of vehicle rollover

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)

■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

■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 low-speed 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.
