Charging
Important Information about
Electric Vehicle Charging
.Charging an electric vehicle
can stress a building’s
electrical system more than
a typical household
appliance.
.Charge cord limits can vary
from vehicle to vehicle, and
increased charging rates can
stress a building’s electrical
system.
.Before plugging into any
electrical outlet, have a
qualified electrician inspect
and verify the electrical
system (electrical outlet,
wiring, junctions, andprotection 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 charging 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.
.Do not use an electrical
outlet that is not properly
grounded.
.Do not use an electrical
outlet that is on a circuit
with other electrical loads.

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

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 Cord Unplugged
Alert :
When on and your
vehicle is locked, your vehicle
will honk the horn and flash
the lights if charge cord
becomes unplugged.
Charge Power Loss Alert :
When on, your vehicle will
honk the horn and flash the
lights if Charging power is
cut off.
DC Fast Charge Battery
Conditioning
If equipped, 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 take longer
to reach the optimal
temperature. While en route to a DC fast
charge station using Google
Maps, DC Fast Charge
Conditioning happens
automatically.
Cabin Pre-Conditioning
Temperature
Allows for the preferred cabin
temperature to be set. During
a planned charging session at
the vehicle's Home Charge
Location, the vehicle cabin is
warmed or cooled to this
temperature if 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
planned charging sessions.
It does so whether the vehicle
is set to Charge Later,
or observing a scheduled
charge. This allows for
charging at a lower cost by
prioritizing charging during the

REDUCED
ACCELERATION DRIVE
WITH CARE
This message displays when
the vehicle's propulsion power
is reduced. A reduction in
propulsion power can affect
the vehicle's ability to
accelerate. If this message is
on, but there is no observed
reduction in performance,
proceed to your destination.
Under certain conditions, the
performance may be reduced
the next time the vehicle is
driven. The vehicle may be
driven while this message is
on, but maximum acceleration
and speed may be reduced.
Anytime this message stayson, or displays repeatedly, the
vehicle should be taken to
your dealer for service as
soon as possible.
This message can be displayed
when the high voltage battery
charge level is low. The vehicle
is limiting power to maximize
range.
Under certain operating
conditions propulsion will be
disabled. Try restarting after
the vehicle has been off for
two minutes.
PROPULSION POWER
REDUCED DUE TO
TEMPERATURE
This message displays when
the vehicle is on, the battery
temperature is low, and when
the vehicle’s performance is
limited. The duration of the
limited vehicle performance
depends, in part, on the high
