Driver knee airbag location
What is the driver knee airbag and how does it work?
The driver knee airbag is a part of the 4Front frontal collision protection system by IMMI -- the leading provider of advanced safety systems for fire
apparatus. During a frontal crash, the knee airbag is inflated. The inflated knee airbag provides a cushion for the driver’s knees during a frontal
impact.
DISCONNECT THE BATTERY
With battery disconnect in the OFF position,
disconnect and isolate the battery negative cable before
beginning knee airbag installation. Allow system capacitor to
discharge for two minutes before beginning installation. Failure
to disconnect the battery could result in accidental airbag
deployment and could cause serious injury or death.
