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
will charge during any rate
period and 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. Electric Rate Plan Selection
Electric rates, or cost per unit,
may vary based on time, weekday/
weekend, and season. During the
day when the demand for electricity
is high, the rates are usually higher
and called Peak rates. At night
when the demand for electricity
is low, the rates are usually lower
and called Off-Peak rates. In some
areas, a Mid-Peak rate is offered.
Contact the utility company to obtain
the rate schedule for your area.
The summer and winter start dates
must be established to use a
summer/winter schedule.
From the Departure Time & Rate
Information screen, press Edit
Electric Rate Schedule.

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.
