Airbag Readiness Light; Passenger Airbag Status Indicator - GMC Yukon 2023 Manual

When the vehicle is started, these lights
come on solid to remind rear passengers to
fasten their seat belt. Then each light may
stay on solid or flash, and a chime may
come on if the rear passenger remains
unbuckled, or becomes unbuckled, when the
vehicle is moving. An X indicates the seat
belt is not buckled. A check mark indicates
the seat belt is buckled.
If the all rear passenger seat belts are
buckled, neither the chime nor the lights
come on.
For information on the front seat belt
reminder lights, see "Driver Seat Belt
Reminder Light" and "Front Passenger Seat
Belt Reminder Light" listed previously.
The rear passenger seat belt reminder light
and chime may come on if an object is put
on the seat such as a briefcase, handbag,
grocery bag, laptop, or other electronic
device. To turn off the reminder light and/or
chime, remove the object from the seat or
buckle the seat belt.

Airbag Readiness Light

This light shows if there is an electrical
problem with the airbag system. It is
located in the instrument cluster. The
system check includes the airbag sensor(s),
the passenger sensing system, the
pretensioners, the airbag modules, the
wiring, and the crash sensing and diagnostic
module. For more information on the airbag
system, see Airbag System 0 34.
The airbag readiness light comes on for
several seconds when the vehicle is started.
If the light does not come on then, have it
fixed immediately.
Warning
If the airbag readiness light stays on
after the vehicle is started or comes on
while driving, it means the airbag system
might not be working properly. The
airbags in the vehicle might not inflate in
a crash, or they could even inflate
without a crash. To help avoid injury,
have the vehicle serviced right away.
Instruments and Controls
If there is a problem with the airbag
system, a Driver Information Center (DIC)
message may also come on.
