To view and change the Charge Settings,
touch Settings. Use the arrows to scroll
through the list, or hold and drag the list.
This screen allows preferences to be set with
regards to how the vehicle charges.
Touching any item will display options for
specifying their behavior.
The Settings screen displays:
Home Charge Location
With a Home Charge Location set, the
vehicle can determine whether it is plugged
in at home, and will charge according to any
existing schedules. The Home Charge
Location can be changed or deleted at this
screen.
The wireless service and GPS satellite
technologies must be available and
operating for features to function properly.
These systems may not operate if the
battery is disconnected, or if the vehicle has
been off for an extended period of time.
If GPS is unavailable, a message displays on
the infotainment screen. GPS functionality
may resume after the next time you drive
the vehicle.
Notifications
This section contains on/off preferences for
multiple notifications triggered during the
Charging session.
Charge Status Feedback : Provides an
audible notification through horn chirps that
accompany changes in the charging status.
Charge Power Loss Alert : When on, your
vehicle will chirp for an extended period of
time if charging power is cut off.
Headlight Charge Status Indicator : When
on, your vehicle s headlights will show the
charging status. As the battery charges,
more LED bars within the headlights will
turn on. The headlights will automatically
turn off when charging is complete.
DC Fast Charge Battery Conditioning
Adjusts the battery to the optimal
temperature for quicker DC Fast Charging.
This should be done before charging at a DC
Fast Charger.
Depending on the outside and battery
temperature, battery conditioning could be
as long as one hour.
Instruments and Controls
While en route using Google Maps, DC Fast
Charge Conditioning happens automatically
if a DC Fast Charge station has been added
to the route.
Cabin Pre-Conditioning Temperature
Allows for the preferred cabin temperature
to be set. During your next charging session,
the vehicle cabin is warmed or cooled to
this temperature if Pre-conditioning is set to
ON in either the Charge Later screen, or in
an active Schedule.
Preferred Charge Times
Allows preferred charge time windows to be
enabled for the Home Charge Location
during both weekday and weekend
scheduled or delayed charging sessions. This
allows for charging at a lower cost by
charging during the electrical provider s
off-peak period. The vehicle will use these
times to reach the desired Charge Level by
the scheduled time. If the vehicle cannot
reach the desired charge level within these
times, it will charge as needed outside of
this schedule.
