IHC
Installation
What is the IHC and how does it work?
IHC stands for Inflatable Head Curtain. In the event of a side roll, the IHC
is deployed by the master roll sensor, at which time a gas generator inflates
the curtain airbag.
The IHC is designed to work in conjunction with a 3-point seat belt.
ALWAYS WEAR YOUR SEAT BELT.
