Driving and Operating
4. Unlatch the DC charging dust cover and
push it to the side.
5. Plug in the DC charge cord into the
vehicle charge port. Make sure that the
DC vehicle plug is fully connected to the
DC charge port. If it is not properly
connected, the vehicle may not be
charged. Check the Driver Information
Center (DIC) to make sure the vehicle
plug is connected properly.
6. Follow the steps listed on the charging
station to start charging.
7. When charging is active, the DC vehicle
plug is locked to the DC charge port and
cannot be disconnected.

Indicator (CSI) illuminates on the
headlamps (if enabled), charge port light
turns on, and an audible chirp occurs.
See Charging Status Feedback 0 260.
Caution
Do not attempt to disconnect the DC
vehicle plug while charging is active. This
action may damage the vehicle or
charging station hardware.
To Stop DC Charging
Automatic
When the vehicle no longer needs power
from the charging station, it stops charging
and the DC vehicle plug unlocks from the DC
charge port.
Energy can still be consumed from the
charging station when the vehicle displays
and indicators show that the battery is fully
charged. This is to ensure the battery is in
optimal temperature operating range to
maximize vehicle range. See Charging 0 108.
To End DC Charging
1. Wait until the charging process has fully
stopped, the DC vehicle plug is unlocked,
and the charging status indicator is solid
green or off. To stop charging at any
time during the charge process, see To
Stop AC or DC Charging later on in this
section.
If the vehicle plug does not unlock from
the vehicle charge port after a charge,
contact Roadside Assistance. See
Roadside Assistance Program 0 374.
