and Safety Information (GMNA-Localizing-U.S./Canada-16832556) - 2023 -
CRC - 9/28/22
68 Instruments and Controls
If the word ON, and the on symbol, are lit
on the passenger airbag status indicator, it
means that the front outboard passenger
frontal airbag is allowed to inflate.
If the word OFF, and the off symbol, are lit
on the passenger airbag status indicator, it
means that the passenger sensing system
has turned off the front outboard passenger
frontal airbag.
If, after several seconds, both status
indicator lights remain on, if there are no
lights at all, or if the airbag readiness light
is on, there may be a problem with the
lights or the passenger sensing system. See
your dealer for service right away.
{
Warning
If the airbag readiness light ever comes
on and stays on, it means that
something may be wrong with the airbag
system. To help avoid injury to yourself
or others, have the vehicle serviced right
away. See Airbag Readiness Light 0 67
for more information, including important
safety information.
Brake System Warning Light
Metric English
This light comes on briefly when the vehicle
is turned on to show that the light is
working. If it does not come on then, have
it fixed so it will be ready to warn you if
there is a problem.
If the light comes on and stays on, there is
a brake problem. Have the brake system
inspected right away. This light may come
on if the brake fluid is low. See your
owner's manual.
If the light comes on while driving, pull off
the road and stop carefully. The brake
system has electric brake boost. Vehicle
speed may be limited when the brake
system warning light comes on. The brake
pedal might be harder to push, or the brake
pedal may go closer to the floor. It could
take longer to stop. If the light is still on,
have the vehicle towed for service. See
Transporting a Disabled Vehicle 0 134.
{
Warning
The brake system might not be working
properly if the brake system warning
light is on. Driving with the brake system
warning light on can lead to a crash.
If the light is still on after the vehicle has
been pulled off the road and carefully
stopped, have the vehicle towed for
service.
Tire Pressure Light
If equipped with the Tire Pressure Monitor
System (TPMS), this light comes on briefly
when the vehicle is started. It provides
information about tire pressures and
the TPMS.
When the Light Is On Steady
This indicates that one or more of the tires
are significantly underinflated.
