presents a summary of the current vehicle
Range, Charge Level, and amount of Range
Gained during the charging session. For
information on beginning a charging session,
see Plug-In Charging 0 253.
For Level 1 chargers, you can also select the
appropriate Charge Cord Limit of either
8 amps or 12 amps. This determines how
much current can flow from an electrical
outlet to the vehicle battery. It also ensures
proper charge time estimates.
When the Charge Cord Limit is changed
from 8 amps to 12 amps on a 120V circuit a
notification is displayed.
If no Home Charge Location is set, the Level
1 Cord Limit will revert to 8 amps every
time the vehicle is shifted out of (P) Park.
Range and charge time estimates fluctuate
depending on a number of factors such as
Charge Cord Level/Limit, battery
temperature, and outside air temperature.

DC Fast Charging
The vehicle will immediately begin charging
when plugged into a DC fast charging
station. While DC Fast Charging, the vehicle
will bypass any schedule or departure time
selection. See Plug-In Charging 0 253.
The Station Power gauge displays the
station's ability to charge at the rate your
vehicle is capable of charging. If you see the
Station Power gauge at the bottom of the
peek-in screen when you are Fast Charging,
the station you are using is not providing as
much power as your vehicle is capable of
receiving. If you regularly see this gauge at
Instruments and Controls
a particular station, consider using another
Fast Charging station, or you can try calling
the station support line if one is displayed.
Reasons the Station Power gauge may
appear, include when:
The station is unable to provide the
amount of energy that your vehicle can
handle.
Multiple vehicles are charging at the
same time and may be affecting the
charge rate.
Power is being limited at the charger.
Schedule
The Energy app s Schedule feature allows a
custom charging plan to be set for each day
of the week. When the vehicle is plugged in
at the Home Charge Location, the Schedule
feature will automatically charge to the
desired Charge Level and pre-condition the
cabin by the time set in the Schedule. This
feature acts as a more customizable Charge
Later setting than the one on the Charging
screen.
