Passenger Sensing System - GMC HUMMER EV 2023 Owner's Manual

The vehicle has a feature that may
automatically unlock the doors, turn on the
interior lamps and hazard warning flashers
after the airbags inflate. The feature may
also activate, without airbag inflation, after
an event that exceeds a predetermined
threshold. After turning the vehicle off and
then on again, the doors can be locked, the
interior lamps can be turned off, and the
hazard warning flashers can be turned off
using the controls for those features. If any
of these systems are damaged in the crash
they may not operate as normal.
Warning
A crash severe enough to inflate the
airbags may have also damaged
important functions in the vehicle, such
as the brake and steering systems, etc.
Even if the vehicle appears to be drivable
after a moderate crash, there may be
concealed damage that could make it
difficult to safely operate the vehicle.
Use caution if attempting to restart the
vehicle after a crash has occurred.
Plug-in vehicles have a high voltage battery
and a standard 12-volt battery.
If an airbag inflates or the vehicle has been
in a crash, the sensing system may shut
down the high voltage system. When this
occurs, the high voltage battery is
disconnected and the vehicle will not start.
Before the vehicle can be operated again, it
must be serviced at your dealer.
In many crashes severe enough to inflate
the airbag, windshields are broken by
vehicle deformation. Additional windshield
breakage may also occur from the front
outboard passenger airbag.
Airbags are designed to inflate only once.
After an airbag inflates, you will need
some new parts for the airbag system.
If you do not get them, the airbag
system will not be there to help protect
you in another crash. A new system will
include airbag modules and possibly other
parts. The service manual for the vehicle
covers the need to replace other parts.
The vehicle has a crash sensing and
diagnostic module which records
information after a crash. See Vehicle
Data Recording and Privacy 0 375 and
Event Data Recorders 0 376.
Seats and Restraints
Let only qualified technicians work on the
airbag system. Improper service can mean
that an airbag system will not work
properly. See your dealer for service.
