Replacing Airbag System
Parts after a Crash
{WARNING
A crash can damage the
airbag systems in the vehicle.
A damaged airbag system
may not work properly and may
not protect you and your
passenger(s) in a crash, resulting
in serious injury or even death. To
help make sure the airbag
systems are working properly
after a crash, have them
inspected and any necessary
replacements made as soon as
possible.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. The SERVICE VEHICLE
SOON message in the Driver
Information Center (DIC) will be
displayed. Before the vehicle can be
operated again, it must be serviced
at your dealer.
If an airbag inflates, you will need to
replace airbag system parts. See
your dealer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly. Have
the vehicle serviced right away. See
Airbag Readiness Light on
page 5‑17
for more information.
Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the
vehicle safety belts.

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 vehicle owner.
The following screens may appear,
depending on the status.
This screen indicates that the
charge cord is not connected. Plug
the charge cord in to charge the
vehicle.

Speedometer
The speedometer shows the vehicle
speed in both kilometers per hour
(km/h) and miles per hour (mph).
The DIC menu can be used to
change the units.
SeeDriver Information Center (DIC)
on page 5‑45.
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
Trip Odometer
The trip odometer is within the
Driver Information Center. See
Driver Information Center (DIC) on
page 5‑45 for more information.
Compass
The vehicle has a compass display
in the instrument cluster above the
speedometer. The compass
receives its heading and other
information from the Global
Positioning System (GPS) antenna
and vehicle speed information.
The compass system has automatic
calibration and zone adjustment
features.
Avoid covering the GPS antenna for
long periods of time with objects
that may interfere with the antenna's
ability to receive a satellite signal.
SeeMulti-Band Antenna on
page 7‑13 for the location of the
vehicle's antenna. The compass
system is designed to operate for a
certain number of miles or degrees
of turn before needing a signal from
the GPS satellites. The compass
system will automatically determine
when a GPS signal is restored and
provide a heading.
Battery Gauge (High
Voltage)
This indicator displays the high
voltage battery charge level.
When this indicator is displayed in
the foreground, the vehicle is
operating in Electric Mode. The
number next to the indicator
displays an estimate of how far the
vehicle can be driven while in
this mode.
See Electric Mode on page 9‑24.

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 fuel, ignition, and emission
control systems. It ensures that
emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.
This light 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 9‑18for more
information.
If the malfunction indicator lamp
comes on and stays on, while the
engine is in ON/RUN, this indicates
that there is an OBD II problem and
service is required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system assists
the dealer technician in correctly
diagnosing any malfunction.
Notice: If the vehicle is
continually driven with this light
on, the emission controls might
not work as well, the vehicle fuel
economy might not be as good,
and the engine might not run as
smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.

If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.
Emissions Inspection and
Maintenance Programs
Some state and local governments
have or might begin programs to
inspect the emission control
equipment on the vehicle. Failure to
pass this inspection could prevent
getting a vehicle registration.The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.
The vehicle may not pass
inspection if:
.The vehicle may not pass this
inspection if the malfunction
indicator lamp is on while the
vehicle is in ON/RUN, or if the
vehicle is placed in Service Only
Mode and the malfunction
indicator lamp does not come
on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.
.The vehicle may not pass this
inspection if the OBD II
(On-Board Diagnostics) system
determines that critical emission
control systems have not been
completely diagnosed by the
system. The vehicle would be
considered not ready for
inspection. This can happen if
the 12‐volt battery has recently
been replaced or if the 12‐volt
battery has run down. The
diagnostic system is designed to
evaluate critical emission control
systems during normal driving.
This can take several days of
routine 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.

The center stack controls only need
a light touch to operate and work
best with bare hands. The controls
will work with most gloves although
they may take longer to respond.
Use the finger pad rather than the
finger tip to minimize response time.
If the controls are not responding,
remove the gloves.

Power Flows
To view the Power Flow screens,
press the
[button on the center
stack and then press the Power
Flow button at the top of the touch
screen. The Power Flow screens
indicate the current system
operating condition. The screens
show the energy flow between the
