Electric Mode; Extended Range Mode - Chevrolet 2011 Volt Owner's Manual

Electric Mode

In Electric Mode, the vehicle does
not use fuel or produce tailpipe
emissions. During this primary
mode, the vehicle is powered
by electrical energy stored in the
high voltage battery. The vehicle
can operate in this mode until the
battery has reached a low charge.
There are some conditions when
the battery charge is high enough
to provide Electric Mode operation,
but the engine still runs. They are:
Cold ambient temperatures.
Hot or cold high voltage battery
temperatures.
The hood being open or not
completely closed and latched.
Certain high voltage battery fault
conditions.
Engine Maintenance Mode
or Fuel Maintenance Mode
being run.

Extended Range Mode

When the vehicle reaches the end
of its electric range, it switches
to Extended Range Mode (ERM).
In this secondary mode, electricity
is produced by the fuel powered
engine. This secondary source of
electric power extends the vehicle
range. Operation will continue
in ERM until the vehicle can be
plugged in to recharge the high
voltage battery and restore
Electric Mode.
The high voltage battery will
continue to provide some power
and work together with the engine
to provide peak performance when
it is required, such as driving up a
steep incline or for high acceleration
maneuvers. The battery will not be
charged nor will electric vehicle
range be restored by the engine.
I n f o r ma t i o n P r o v i d e d b y :
Driving and Operating
In either Electric Mode or Extended
Range Mode, when the hood is
open, the engine will run without
turning off if the vehicle is on.
The high voltage battery is neither
charged nor discharged when this
occurs.
In either Electric Mode or Extended
Range Mode, if there is a high
voltage battery fault, the engine
may run without turning off to
generate needed electricity.
The Malfunction Indicator Lamp
will turn on. See Malfunction
Indicator Lamp on page 5 21.
