The main SRS airbag system and Pop Up Hood components are shown above.
The SRS airbag system and Pop Up Hood are controlled by the airbag sensor
assembly. 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.
When the Pop Up Hood is activated, a non-toxic gas is released due to a chemi-
cal reaction in the lifters, which causes the pistons to eject quickly and raise the
rear portion of the hood. (Pop Up Hood: →P. 5 6 )

IS300h_EE(OM53C61E)
When the sensors located at the back of the front bumper detect an impact with
a body, such as a pedestrian, which meets or exceeds the threshold level while
the vehicle is being driven within the operational speed range, the system
becomes operational and raises the rear portion of the hood.
Sensors
Hood
Lifters
Pop Up Hood
In the event of a frontal collision with a body, such as a pedestrian, the Pop Up
Hood system raises the rear portion of the hood to reduce the possibility of a
serious impact to the pedestrian’s head area by adding clearance to the
engine compartment.
