Programmable Charging
(PLUG-IN Only)
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 you plug in to 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 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.

remaining distance the vehicle can be
driven combining the electric range
and fuel range.
Average Fuel Economy (Base
