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
This feature is available on some
models. 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 AC
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
The Charge Level Preference
settings are not directly related to
the Charge Level Button on the
charge cord. The vehicle will adhere
to the setting that minimizes the AC
current used to charge the vehicle.

Charge Rate Selection
From the Delayed Rate and
Departure Time Charge Mode
Status screen, press Edit.
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.

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 can
be disabled through vehicle
personalization. See
“Energy
Summary Exit Pop-up” under
Vehicle Personalization on
page 5‑56.
