Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the propulsion
system is started to indicate they
are working.
Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Waiting to do repairs can be
costly and even dangerous.
Instrument Cluster
The instrument cluster displays a
preview of information that includes
electric range, charging, odometer,
and battery status. This happens
upon entry when the driver door is
opened, and following the welcome
animation, before starting the
vehicle.
A CHARGING OVERRIDE/
INTERRUPTION OCCURRED
message may display on the lower
left of the screen to indicate that a
charging override or interruption has
occurred due to one or more of the
following events:
.Override of the charge settings
by the owner using OnStar.
.Unintended interruption of AC
power at the vehicle's
charge port.
.Interruption of charging by the
utility company using OnStar as
authorized by the vehicle owner.
There are several screens that will
display depending on the current
charging status.

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.If there is a problem with the airbag
system, a Driver Information Center
(DIC) message may also come on.
See
Airbag System Messages on
page 5-48.
Passenger Airbag Status
Indicator
The vehicle has a passenger
sensing system. See Passenger
Sensing System on page 3-23 for
important safety information. The
passenger airbag status indicator is
in the overhead console.
United States
Canada
When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF, or the symbol
for on and off, for several seconds
as a system check. Then, after
several more seconds, the status
indicator will light either ON or OFF,
or the on or off symbol, to let you
know the status of the front
outboard passenger frontal airbag
and knee airbag.

If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the front
outboard passenger frontal airbag
and knee airbag are allowed to
inflate.
If the word OFF or the off symbol is
lit on the airbag status indicator, it
means that the passenger sensing
system has turned off the front
outboard passenger frontal airbag
and knee airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.
{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,(Continued)
Warning (Continued)
have the vehicle serviced right
away. SeeAirbag Readiness
Light on page 5-14 for more
information, including important
safety information.
Charging System Light
(12-Volt Battery)
The charging system light comes on
briefly when the vehicle is in ON/
RUN, as a check to show the light is
working.
If the light stays on, or comes on
while driving, there could be a
problem with the electrical charging system. Have it checked by your
dealer. Driving while this light is on
could drain the 12‐volt battery.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the vehicle. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping to
maintain a clean environment. The
malfunction indicator lamp comes
on when the vehicle is placed in
Service Only Mode, as a check to
show it is working. If it does not,
have the vehicle serviced by your
dealer. See
Power Button on
page 9-16 for more information.

.The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed by the
system. If this were to occur, the
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or
run down.
The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of driving. If this
has been done and the vehicle
still does not pass the inspection
for lack of OBD II system
readiness, your dealer can
prepare the vehicle for
inspection.Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.
MetricEnglish
This light comes on briefly when the
vehicle is turned on. If it does not
come on then, have it fixed so it will
be ready to warn if there is a
problem.
If the light comes on and stays on,
there is a base brake problem.
{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.
Electric Parking Brake
Light
This status light comes on when the
parking brake is applied. If the light
flashes and stays on after the

parking brake is released, or while
driving, there is a problem with the
electric parking brake system.
If the light does not come on,
or remains flashing, see your dealer.
SeeElectric Parking Brake on
page 9-31 for more information.
Service Electric Parking
Brake Light
The service electric parking brake
light should come on briefly when
the vehicle is in ON/RUN. If it does
not come on, have the vehicle
serviced by your dealer.
If this light stays on, there is a
problem with a system on the
vehicle that is causing the parking
brake system to work at a reduced level. The vehicle can still be driven,
but should be taken to a dealer as
soon as possible. See
Electric
Parking Brake on page 9-31. If a
message displays in the Driver
Information Center (DIC), see Brake
System Messages on page 5-43.
Antilock Brake System
(ABS) Warning Light
This light should come on briefly
when the vehicle is in ON/RUN. If it
does not come on, have the vehicle
serviced by your dealer. If the ABS warning light stays on
longer than a few seconds after the
vehicle is in ON/RUN, or comes on
and stays on while driving, try
resetting the system. To reset the
system:
1. While driving, pull over when it is
safe to do so.
2. Place the vehicle in P (Park).
3. Turn the vehicle off.
4. Restart the vehicle.
If the ABS warning light remains on
after resetting the system or comes
on again while driving, the vehicle
needs service. If the ABS warning
light is on, but the regular brake
system warning light is not on, the
antilock brakes are not working
properly, but the regular brakes are
still functioning. Have the vehicle
serviced right away. If both brake
lights are on, the vehicle does not
have antilock brakes, and there is a
problem with the regular brakes as
