Passenger Sensing
System
The passenger sensing system,
if equipped, turns off the front
outboard passenger frontal airbag
under certain conditions. No other
airbag is affected by the passenger
sensing system.
If the vehicle has one of the
indicators pictured in the following
illustrations, then the vehicle has a
passenger sensing system for the
right front passenger position unless
there is an airbag off switch located
in the glove box.
If there is an airbag off switch, the
vehicle does not have a passenger
sensing system. SeeAirbag On-Off
Switch on page 3‑28 for more
information.
The passenger airbag status
indicator will be visible on the
overhead console when the vehicle
is started.
