IN BRIEF 29
{Danger
Improper use of portable electric
vehicle charge cords may cause a
fire, electrical shock, or burns, and
may result in damage to property,
serious injury, or death.. Do not use extension cords,
multi-outlet power strips,
splitters, grounding adaptors,
surge protectors, or similar
devices.
. Do not use an electrical outlet
that is worn or damaged,
or will not hold the plug
firmly in place.
. Do not use an electrical outlet
that is not properly grounded.
. Do not use an electrical outlet
that is on a circuit with other
electrical loads.
Charge Cord Status Indicators
See Charge Cord (PLUG-IN Only) 0279.
Charge Level Selection
Charge level selection can be made
using the Charge Limit Preference
screen on the infotainment display.
See “Charge Limit Selection ”under
Programmable Charging (PLUG-IN Only)
0 152.
{Warning
Using a charge level that exceeds
the electrical circuit or electrical
outlet capacity may start a fire or
damage the electrical circuit. Use
the lowest charge level until a
qualified electrician inspects the
electrical circuit capacity. Use the
lowest charge level if the electrical
circuit or electrical outlet capacity
is not known.
Regenerative Braking
Regenerative braking takes some of
the energy from the moving vehicle
and turns it back into electrical
energy. This energy is then stored in
the high voltage battery system, contributing to increased energy
efficiency. See
Regenerative Braking
(PLUG-IN Only) 0237.
Service
{Warning
Never try to do your own service on
high voltage components. You can
be injured and the vehicle can be
damaged if you try to do your own
service work. Service and repair of
these high voltage components
should only be performed by a
trained service technician with the
proper knowledge and tools. See
Doing Your Own Service Work 0298.

136 INSTRUMENTS AND CONTROLS
Here are four things that some owners
ask about. None of these show a
problem with the fuel gauge:
.At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel to
fill up than the gauge indicated.
For example, the gauge may have
indicated the tank was half full,
but it actually took a little more or
less than half the tank's capacity
to fill the tank.
. The gauge moves a little while
turning a corner or speeding up.
. The gauge takes a few seconds to
stabilize after the ignition is
turned on, and goes back to empty
when the ignition is turned off.Power Indicator Gauge
(PLUG-IN Only)
The power gauge shows the vehicle’s
total power consumption coming from
the engine and/or battery.
When the power indicator is green,
battery power is being regenerated.
The blue area indicates power
provided by the engine and/or battery.
The yellow area shows high power
usage. Operating the vehicle closer to
the zero power position both during
acceleration and braking will result in
higher efficiency.

154 INSTRUMENTS AND CONTROLS
Delay (Electric 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.
Also, if the selected electric rate
settings result in a very long charge
completion time, the vehicle will start
charging immediately upon plug-in.
For example, if the electric rate table
is set up with all “Peak”rates and the
rate preference is to charge during “Off-Peak”
rates only, then the vehicle
will start charging immediately upon
plug-in.
Charge Limit Selection
The Charge Limit Preference setting
allows the customer to select their
vehicle’s charge level so it matches the
capability of their charging location.
If the vehicle consistently stops
charging after plugging in, or if a
circuit breaker continues to trip,
reducing to a lower Charge Limit
Preference may resolve the issue.
The Charge Limit Preference should be
configured to match the electrical
current rating for the electrical outlet
that the charge cord is connected to.
The Charge Limit Preference
settings are: .
Maximum: Limits AC current to
12 amps
. Reduced: Limits AC current to
8 amps
Exact current levels may vary from
the values shown in this manual.
Check the vehicle for the current
available levels.
The Charge Limit Preference setting
can be changed at any time while the
infotainment display is operable.
For some vehicles, the Charge Limit
Preference must be updated prior to
the vehicle being charged and the
Charge Limit Preference will reset to a
default value when the vehicle is
shifted from P (Park).
{Warning
Using a charge level that exceeds
the electrical circuit or electrical
outlet capacity may start a fire or
damage the electrical circuit. Use
the lowest charge level until a
qualified electrician inspects the
electrical circuit capacity. Use the (Continued)

428 ONSTAR
Advisors are available in English,
Spanish, and French. Available
languages may vary by country.
Potential Issues
OnStar cannot perform Remote Door
Unlock or Stolen Vehicle Assistance
after the vehicle has been off
continuously for 10 days without an
ignition cycle. If the vehicle has not
been started for five days, OnStar can
contact Roadside Assistance or a
locksmith to help gain access to the
vehicle.
Global Positioning System (GPS)
.Obstruction of the GPS can occur
in a large city with tall buildings;
in parking garages; around
airports; in tunnels and
underpasses; or in an area with
very dense trees. If GPS signals are
not available, the OnStar system
should still operate to call OnStar.
However, OnStar could have
difficulty identifying the exact
location. .
In emergency situations, OnStar
can use the last stored GPS
location to send to emergency
responders.
A temporary loss of GPS can cause
loss of the ability to send a
Turn-by-Turn Navigation route. The
Advisor may give a verbal route or
may ask for a call back after the
vehicle is driven into an open area.
Cellular and GPS Antennas
Cellular reception is required for
OnStar to send remote signals to the
vehicle. Do not place items over or
near the antenna to prevent blocking
cellular and GPS signal reception.
Unable to Connect to OnStar
Message
If there is limited cellular coverage or
the cellular network has reached
maximum capacity, this message may
come on. Press
Qto try the call again
or try again after driving a few miles
into another cellular area.
Vehicle and Power Issues
OnStar services require a vehicle
electrical system, wireless service, and
GPS satellite technologies to be
available and operating for features to
function properly. These systems may
not operate if the battery is
discharged or disconnected.
Add-on Electrical Equipment
The OnStar system is integrated into
the electrical architecture of the
vehicle. Do not add any electrical
equipment. See Add-On Electrical
Equipment 0295. Added electrical
equipment may interfere with the
operation of the OnStar system and
cause it to not operate.
Vehicle Software Updates
OnStar or GM may remotely deliver
software updates or changes to the
vehicle without further notice or
consent. These updates or changes
may enhance or maintain safety,
security, or the operation of the
vehicle or the vehicle systems.
Software updates or changes may
affect or erase data or settings that
are stored in the vehicle, such as
