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.

Electrical System
High Voltage Devices and
Wiring
{WARNING
Exposure to high voltage
can cause shock, burns, and
even death. The high voltage
components in the vehicle can
only be serviced by technicians
with special training.
High voltage components are
identified by labels. Do not
remove, open, take apart,
or modify these components.
High voltage cable or wiring has
orange covering. Do not probe,
tamper with, cut, or modify high
voltage cable or wiring.
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed.
This greatly reduces the chance
of circuit overload and fire caused
by electrical problems.
Fuses and circuit breakers protect
the following in the vehicle:
.Headlamp Wiring
.Windshield Wiper Motor
.Power Windows and other
Power Accessories
Replace a bad fuse with a new one
of the identical size and rating.
