Remove the cover to access and
replace when not in use.
Certain accessory plugs may
not be compatible with the
accessory power outlet and
could overload vehicle or adapter
fuses. If a problem is experienced,
see your dealer.
When adding electrical equipment,
be sure to follow the installation
instructions included with the
equipment. SeeAdd-On Electrical
Equipment on page 9‑63.
Notice: Hanging heavy
equipment from the power
outlet can cause damage not
covered by the vehicle warranty.
The power outlets are designed
for accessory power plugs only,
such as cell phone charge cords.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. This indicates that
an override of the charge settings
by the owner via OnStar has
occurred.

5-16 Instruments and Controls
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 7‑18 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 9‑25.
Fuel Gauge
This indicator displays the fuel
level. When this indicator is in the
foreground, the vehicle is operating
in Extended Range Mode.
The number next to the indicator
displays an estimate of how far
the vehicle can be driven while
in this mode.
SeeExtended Range Mode on
page 9‑25.

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,
have the vehicle serviced right
away. SeeAirbag Readiness
Light on page 5‑19 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 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 9‑18
for more information.

.The vehicle will not pass
this inspection if the OBD II
(On-Board Diagnostic) 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.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.
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.

Information Displays
Center Stack Display
The center stack screen displays
Charging, Power Flow, and Energy
Information. See the information that
follows.
The Climate Control, Infotainment,

display information in this screen.
For more information on these
systems, see:
.Automatic Climate Control
System on page 8‑1.

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.To view the Power Flow, Charging,

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

operating condition. The screens
show the energy flow between the
engine, electric drive unit, and high

Delayed Departure Time:The
vehicle estimates the charging start
time considering the programmed departure time for the current day
of the week. Charging begins at the
start time and is complete by the
departure time only if sufficient time
is allowed after the charge cord is
plugged in. The vehicle uses an
internal clock for programmable
charging, not the clock in the
center stack.
Delayed Rate and Departure
Time:
The vehicle estimates the
charging start time based on the
utility rate schedule, utility rate
preference, and the programmed
departure time for the current day of
the week. The vehicle will charge
during the least expensive rate
periods to achieve a full battery
charge by the departure time.
Electrical rate information from the
utility company for the charging
location is required for this mode.
