Srs Airbag Deployment Conditions (Srs Front Airbags); Srs Airbag Deployment Conditions; Types Of Collisions That May Not Deploy The Srs Airbags - Lexus NX200 2017 Owner's Manual

SRS airbag deployment conditions (SRS front airbags)

■
The SRS front airbags will deploy in the event of an impact that exceeds the set thresh-
●
old level (the level of force corresponding to an approximately 20 - 30 km/h
[12 - 18 mph] frontal collision with a fixed wall that does not move or deform).
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 pretensioners will
●
activate.
The SRS seat cushion airbag on the front passenger seat will not operate if the occu-
●
pant is not wearing a seat belt.
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 1500 kg [3300 lb.] vehicle colliding with the vehicle
cabin from a direction perpendicular to the vehicle orientation at an approximate
speed of 20 - 30 km/h [12 - 18 mph]).
The SRS side and curtain shield airbags may also deploy in the event of a severe frontal
●
collision.
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 seri-
ous impact occurs to the underside of your vehicle. Some examples are shown in the
illustration.
Hitting a curb, edge of pavement or hard sur-
●
face
Falling into or jumping over a deep hole
●
Landing hard or falling
●
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
