Programmable Charging
Important Information About
Portable Electric Vehicle Charging
.Charging an electric vehicle can
stress a building’s electrical
system more than a typical
household appliance.
.Before you plug in to any
electrical outlet, have a qualified
electrician inspect and verify the
electrical system (electrical
outlet, wiring, junctions, and
protection devices) for
heavy-duty service at a 12 amp
continuous load.
.Electrical outlets may wear out
with normal usage or be
damaged over time, making
them unsuitable for electric
vehicle charging.
.Check the electrical outlet/plug
while charging and discontinue
use if the electrical outlet/plug is
hot, then have the electrical
outlet serviced by a qualified
electrician.

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.
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.
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 Level Selection
The Charge Level 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 Level Preference may
resolve the issue.
The Charge Level Preference
should be configured to match the
electrical current rating for the
electrical outlet that the charge cord
is connected to. The Charge Level
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 Level Preference
setting can be changed at any time
while the center stack display is
operable.

Select one of the following:
.Edit Electric Rate Schedule.
.Edit Departure Time Schedule.
See“Departure Time Entry.”
.Select Charge Rate Preference.
Charge Rate Preference Selection
From the Departure Time & Rate
Information screen, press Select
Charge Rate Preference.
Press one of the following options to
select the Charge Rate Preference:
.Charge during Peak, Mid-Peak,
and Off-Peak Rates: The vehicle
can charge during any rate
period to satisfy the next
planned departure time.
However, it will select when to
charge to minimize the total cost
of the charge.
.Charge during Mid-Peak and
Off-Peak Rates: The vehicle will
charge during Off-Peak and/or
Mid-Peak rate periods only and
will select when to charge to
minimize the total cost of the
charge.
.Charge during Off-Peak Rates:
The vehicle will only charge
during Off-Peak rate periods.
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.
For example, if the vehicle is
plugged in for only one hour prior to
the departure time, and the battery
is completely discharged, the
vehicle will not be fully charged by
the departure time regardless of the
rate selection.
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.

Energy Information
To view the Energy Usage, Energy
Efficiency, and Efficiency Tips, press
the
[button on the center stack
and then press the Energy Info
button at the top of the touch
screen.
Energy Usage
The Energy Usage screen displays
information for the total of all drive
cycles since the last time the high
voltage battery was fully charged.
This includes distance traveled in
Electric Mode, distance traveled in
Extended Range Mode, total
distance traveled, electric energy
used from the battery, total fuel used, and average fuel economy.
There are maximum limits to some
of the values that can be displayed.
When these values are replaced
with dashes, the value limits have
been reached. To reset these
values, the high voltage battery will
need to be fully recharged. The
circle graph also represents
the percentage of distance traveled
using Electric Mode versus
Extended Range Mode. The
Lifetime Fuel Economy is a total
over the life of the vehicle and can
only be reset by the dealer.
The Energy Usage information will
also appear automatically on power
off when Retained Accessory Power
is active. This automatic pop-up canbe disabled through vehicle
personalization. See
“Energy
Summary Exit Pop Up” under
Vehicle Personalization on
page 5-50.
Energy Efficiency
The Energy Efficiency screen is
accessed by pressing Energy
Efficiency on the Energy Usage
screen. This screen displays the
energy efficiency over the drive
cycle based on driving style and
climate settings. Driving in a more
efficient manner will result in a
higher percentage displayed for
driving style. Minimizing the use of
