Electric Vehicle
Operating Modes
System Operation
This vehicle is an Extended Range
Electric Vehicle (EREV). It uses an
electric propulsion system to drive
the vehicle at all times. Electricity
is the vehicle's primary source of
energy, while gasoline is the
secondary source.
The vehicle has two modes of
operation: Electric and Extended
Range. In both modes, the vehicle
is propelled by its electric drive unit.
It converts electrical energy into
mechanical energy to drive the
wheels. The vehicle's performance
remains the same in either mode.
See Driving for Better Energy
Efficiency on page 9‑2.

WARNING (Continued)
.There are holes or openings
in the vehicle body from
damage or aftermarket
modifications that are not
completely sealed.
If unusual fumes are detected or
if it is suspected that exhaust is
coming into the vehicle:
.Drive it only with the windows
completely down.
.Have the vehicle repaired
immediately.
Never park with the engine
running in Extended Range Mode
in an enclosed area such as a
garage or a building that has no
fresh air ventilation.
Running the Vehicle
While Parked
It is better not to park with the
propulsion system on. But if you
ever have to, here are some things
to know.
{WARNING
Leaving the engine running
in Extended Range Mode
in an enclosed area with poor
ventilation is dangerous. Engine
exhaust may enter the vehicle.
Engine exhaust contains Carbon
Monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even
death. Never run the engine
in an enclosed area that has no
fresh air ventilation. For more
information, see Engine Exhaust
on page 9‑30.
{WARNING
It can be dangerous to get out of
the vehicle if the electric drive unit
shift lever is not fully in P (Park)
with the parking brake firmly set.
The vehicle can roll. Do not leave
the vehicle with the propulsion
system on unless you have to.
If you have left the propulsion
system on, the vehicle can move
suddenly. You or others could be
injured. To be sure the vehicle
will not move, even when you are
on level ground, always set the
parking brake and move the shift
lever to P (Park).
Follow the proper steps to
be sure the vehicle will not move.

Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The
Yswitch is
on the center stack. The EPB can
always be activated, even if the
vehicle is off. To prevent draining
the 12‐volt battery, avoid repeated
cycles of the EPB system when
the vehicle is off.
In case of insufficient electrical
power, the EPB cannot be applied
or released.
Before leaving the vehicle, check
the Electric Parking Brake Light to
ensure the parking brake is applied.
EPB Apply
The EPB can be applied anytime
the vehicle is stopped. The EPB is
applied by momentarily lifting up on
the
Yswitch. Once fully applied,
the Electric Parking Brake Light will
be on. While the brake is being
applied, the Electric Parking Brake
Light will flash until full apply is
reached. If the light does not come
on, or remains flashing, have the
vehicle serviced. Do not drive the
vehicle if the Electric Parking Brake
Light is flashing. See your dealer.
If the EPB is applied while the
vehicle is in motion, a chime will
sound, and the DIC message
RELEASE PARKING BRAKE
will be displayed. The vehicle
will decelerate as long as the
switch is held in the up position. Releasing the
Yswitch during the
deceleration will release the parking
brake. If the
Yswitch is held in
the up position until the vehicle
comes to a stop, the EPB will
remain applied.
If the Electric Parking Brake Light
flashes continuously, the EPB is
only partially applied or released,
or there is a problem with the EPB.
The DIC message SERVICE
PARKING BRAKE will be displayed.
If this light flashes continuously,
release the EPB, and attempt to
apply it again. If this light continues
to flash, do not drive the vehicle.
See your dealer.
If the Service Electric Parking Brake
Light is on, the EPB has detected a
system problem and is operating
with reduced functionality.

To apply the EPB when this
light is on, lift up on the
Yswitch
and hold it in the up position.
Full application of the parking brake
by the EPB system may take a
longer period of time than normal
when this light is on. Continue to
hold the
Yswitch until the Electric
Parking Brake Light remains on.
If the Service Electric Parking
Brake Light is on, see your dealer.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
For maximum EPB force when
parking on a hill, pull the EPB
switch twice.
EPB Release
To release the EPB, place the
vehicle in ON/RUN, apply and hold
the brake pedal, and push down
momentarily on the
Yswitch.
If attempting to release the EPB
without the brake pedal applied,
a chime will sound, and the DIC
message STEP ON BRAKE TO
RELEASE PARK BRAKE will be
displayed. The EPB is released
when the Electric Parking Brake
Light is off.
If the Service Electric Parking
Brake Light is on, the EPB has
detected a system problem, and is
operating with reduced functionality.
To release the EPB when this light
is on, push down on the
Yswitch
and hold it in the down position.
EPB release may take a longer
period of time than normal when
this light is on. Continue to hold
the
Yswitch until the Electric
Parking Brake Light is off. If the
light is on, see your dealer. Notice:
Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
Electric Parking Brake Light is
off before driving.
Automatic EPB Release
The EPB will automatically release
if the vehicle is running, placed
into gear, and an attempt is
made to drive away. Avoid rapid
acceleration when the EPB is
applied, to preserve parking
brake lining life.
