Only a trained service technician with
the proper knowledge and tools
should inspect, test, or replace the
high voltage battery. See your dealer if
either the 12-volt battery or the high
voltage battery needs service.
Charging
This section explains the process for
charging the high voltage battery. Do
not allow the vehicle to remain in
temperature extremes for long periods
without being driven or plugged in.
It is recommended that the vehicle be
plugged in when temperatures are
below 0 °C (32 °F) and above 32 °C
(90 °F) to maximize high voltage
battery life.
When using the portable charge cord
included with the vehicle, it will take
approximately 20 hours to charge the
vehicle with the 8 amp AC current
setting or 12.5 hours using the
12 amp AC current setting. When
using a charging station capable of
16 amps or more, it will take
approximately 4.5 hours to charge the
vehicle. Charge times will vary with
outside temperature. There are three
ways to program how the vehicle is
charged. See
.
The charging system may run fans
and pumps that result in sounds from
the vehicle while it is turned off.
Additional unexpected clicking sounds
may be caused by the electrical
devices used while charging.
While the charge cord is plugged into
the vehicle, the vehicle cannot be
driven.
