.Long Flashing Green –Vehicle is plugged
in. Battery is not fully charged. Battery
charging is delayed.
.Solid Green –Vehicle is plugged in.
Battery is fully charged.
.Solid Yellow –Vehicle is plugged in. It is
normal for the CSI to turn yellow for a
few seconds after plugging in a
compatible charge cord. The CSI may stay
solid yellow longer depending on the
vehicle and if there is a total utility
interruption. See Utility Interruption of
Charging 0194. This may also indicate
that the charging system has detected a
fault and will not charge the battery. See
“Charge Cord Status Indicators” under
Charge Cord 0189. If the vehicle is plugged in and vehicle
power is on, the CSI will flash or will be
solid green, depending on the charge level.
If the vehicle is plugged in and the CSI is
off, a total utility interruption or a charging
fault has been detected. See
Utility
Interruption of Charging 0194 or“Charge
Cord Status Indicators” underCharge Cord
0 189.

Important Information about Portable Electric
Vehicle Charging
.Charging an electric vehicle can stress a
building’s electrical system more than a
typical household appliance.
.Before plugging into any electrical outlet,
have a qualified electrician inspect and
verify the electrical system (electrical
outlet, wiring, junctions, and protection
devices) for heavy-duty service at a
12 amp continuous load.
.Electrical outlets may wear out with
normal usage or may be damaged over
time, making them unsuitable for electric
vehicle charging.
.Check the electrical outlet/plug while
charging and discontinue use if the
electrical outlet/plug is hot, then have the
electrical outlet serviced by a qualified
electrician.
.When outdoors, plug into an electrical
outlet that is weatherproof while in use.
.Mount the charge cord to reduce strain
on the electrical outlet/plug.
.Do not place the charge cord in a position
where it is expected to be submerged in
water.
{Danger
Improper use of portable electric vehicle
charge cords may cause a fire, electrical
shock, or burns, and may result in
damage to property, serious injury,
or death.
.Do not use extension cords,
multi-outlet power strips, splitters,
grounding adaptors, surge protectors,
or similar devices.
.Do not use an electrical outlet that is
worn or damaged, or will not hold the
plug firmly in place.

FCC Information
SeeRadio Frequency Statement 0271.
Utility Interruption of Charging
This vehicle will respond to requests through
the utility company to limit or completely
block electrical power grid usage. This
feature is inactive during DC charging.
A utility interruption of charging will
lengthen the vehicle charge time.
When electrical grid power is completely
blocked, the vehicle will delay charging until
the utility interruption has expired. The
vehicle should be left plugged in so that the
vehicle can automatically begin charging. Changing the charge mode to Immediate or
performing a delayed charging override will
not disable a utility interruption. Unplugging
and plugging the car back in will also not
disable a utility interruption.
A pop-up will appear in the infotainment
display while starting the vehicle following
any utility interruption. See
“Charging
Interrupted or Overridden Pop-Up” under
Programmable Charging 090.
A message will display on the instrument
cluster indicating that a utility interruption
has occurred.
