Passenger Sensing System
If your rearview mirror has one of the indicators pictured
in the following illustrations, your vehicle has a passenger
sensing system. The indicator will be visible when you
turn your ignition key to START or RUN. The words ON
and OFF or the symbol for on and off, will be visible on
the rearview mirror during the system check. When the
system check is complete, either the word ON or the word
OFF, or the symbol for on or the symbol for off will be
visible. See
Passenger Air Bag Status Indicator on
page 3-39. If your rearview mirror doesn't have either of
the indicators pictured, then your vehicle doesn't have the
passenger sensing system.The passenger sensing system will turn off the right
front passenger's frontal air bag under certain
conditions. The driver's air bag and the side air bags
are not part of the passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger's seat and safety belt.
The sensors are designed to detect the presence of a
properly-seated occupant and determine if the
passenger's frontal air bag should be enabled (may
in¯ate) or not. Passenger Air Bag Status Indicator ± United States
