er than 7 °F (-14 °C) or the driver
turns off the heating or cooling sys-
tem the vehicle returns to its default
(EV) mode.
Maintaining Hybrid mode tocontinue heating or air condi-tioning (Plug-in hybrid vehicle)
This message is displayed when the
vehicle maintains the HEV mode to
allow heating or air conditioning. The
mode does not change when the
driver presses the [EV/HEV] button
to switch from the HEV mode to EV
mode while the heating and cooling
system is on and the coolant temper-
ature is below 7 °F (-14 °C).

■ HPCU (Hybrid Power Control Unit)*1
■ High Voltage Battery System*2
Never touch orange colored or
high voltage labeled compo-
nents, including wires, cables,
and connections. When the insu-
lators or covers are damaged or
removed, severe injury or death
from electrocution may occur.
WARNING
While replacing the fuses in the
engine compartment, never
touch the HPCU. The HPCU car-
ries high voltage. Touching the
HPCU may result in electrocu-
tion, serious injury, or death.
WARNING
In the hybrid system, the hybrid
battery uses high voltage to
operate the motor and other
components. This high voltage
hybrid battery system can be
very dangerous. Never touch the
hybrid system. When you touch
the hybrid battery system, seri-
ous injury or death may occur.
