Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The switch 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.The system has a red parking brake
status light and an amber parking
brake warning light. See
Electric
Parking Brake Light on page 5-22
and Service Electric Parking Brake
Light on page 5-22. There are also
parking brake-related Driver
Information Center (DIC) messages.
See Brake System Messages on
page 5-46. In case of insufficient
electrical power, the EPB cannot be
applied or released.
Before leaving the vehicle, check
the red parking brake status light to
ensure that the parking brake is
applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Pull the EPB switch momentarily. The red parking brake status light
will flash and then stay on once the
EPB is fully applied. If the red
parking brake status light flashes
continuously, then the EPB is only
partially applied or there is a
problem with the EPB. A DIC
message will display. Release the
EPB and try to apply it again. If the
light does not come on, or keeps
flashing, have the vehicle serviced.
Do not drive the vehicle if the red
parking brake status light is flashing.
See your dealer. See
Electric
Parking Brake Light on page 5-22.
If the amber parking brake warning
light is on, lift up on the EPB switch
and hold it up. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light is on,
see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is
held up. If the switch is held up until
the vehicle comes to a stop, the
EPB will remain applied.

9-32 Driving and Operating
The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is
normal, and is done to periodically
check the correct operation of the
EPB system.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
EPB Release
To release the EPB:
1. Place the vehicle in ON/RUN.
2. Apply and hold the brake pedal.
3. Push momentarily on the EPBswitch.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by
pushing down on the EPB switch
and holding it down. Continue to
hold the switch until the red parking
brake status light is off. If either light
stays on after release is attempted,
see your dealer.
{Caution
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 brake
warning 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.
Regenerative Braking
Regenerative braking takes some of
the energy from the moving vehicle
and turns it back into electrical
energy. This energy is then stored
back into the high voltage battery
system, contributing to increased
energy efficiency. The hydraulic disc brakes work with
the regenerative braking to ensure
effective braking, such as when a
high braking demand is requested.
The braking system is computer
controlled and blends the
regenerative braking with the
conventional hydraulic disc brakes
to meet any requirements for
deceleration. The controller
interprets the braking request and
uses regenerative braking,
conventional hydraulic braking, or a
combination of both as necessary.
Because the controller applies the
hydraulic brakes through its high
pressure accumulator, you may
occasionally hear the motor‐driven
pump when it recharges the system.
This is normal.
See
Warning Lights, Gauges, and
Indicators on page 5-8 andDriver
Information Center (DIC) on
page 5-43. In the event of a
controller problem, the brake pedal
may be harder to push and the
stopping distance may be longer.

Warning (Continued)
also not detect a lane on winding
or hilly roads, or in conditions that
can limit visibility such as fog,
rain, or snow, or if the headlamps
or windshield are not cleaned or
in proper condition. Keep the
windshield, headlamps, and
camera sensors clean and in
good repair.
LDW warnings may occur due to tar
marks, shadows, cracks in the road,
or other road imperfections. This is
normal system operation; the
vehicle does not need service.
Charging
Plug-In Charging
This section explains the process
for charging the vehicle's 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 a 120-volt AC electrical
outlet, it will take approximately
10 hours to charge the vehicle with
the 12 amp AC current setting or
16 hours using the default 8 amp
AC current setting. When using a
240-volt charging station, it will take
approximately four hours to charge
the vehicle. Charge times will vary
with outside temperature. There are three ways to program how the
vehicle is charged. See
Programmable Charging on
page 5-31.
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.

Charging Status
Feedback
The vehicle has a Charging Status
Indicator (CSI) at the center of the
instrument panel near the
windshield. When the vehicle is
plugged in and the vehicle power is
off, the CSI indicates the following:
.Solid Green –Vehicle is plugged
in. Battery is not fully charged.
Battery is charging.

.Long Flashing Green–Vehicle
is plugged in. Battery is not fully
charged. Battery charging is
delayed.
.Short Flashing Green –Vehicle
is plugged in. Battery is fully
charged.
.Solid Yellow –Vehicle is plugged
in. It is normal for the CSI to turn
yellow for a few seconds after
plugging in a compatible charge
cord. The solid yellow may be
extended depending on the
vehicle and if there is a total
utility interruption via OnStar. See
Utility Interruption of
Charging on page 9-54. This
may also indicate that the
charging system has detected a
fault and will not charge the
battery. See “Charge Cord
Status Indicators” in the charge
cord user guide.
The system may be thermally
conditioning the battery during any
of the states above, requiring
electrical energy to be transferred to
the vehicle. If the vehicle is plugged in and
vehicle power is on, the CSI will be
on solid green. The same is true
during a remote start if the vehicle is
plugged in.
If the vehicle is plugged in and the
CSI is off, a total utility interruption
using OnStar or a charging fault has
been detected. See
Utility
Interruption of Charging on
page 9-54 or“Charge Cord Status
Indicators” in the charge cord user
guide.

Charge Level Selection
Charge level selection can be made
using the Charge Level Preference
setting on the center stack. See
“Charge Level Selection”under
Programmable Charging on
page 5-31.
{Warning
Using a charge level that exceeds
the electrical circuit or electrical
outlet capacity may start a fire or
damage the electrical circuit. Use
the lowest charge level until a
qualified electrician inspects your
electrical circuit capacity. Use the
lowest charge level if the
electrical circuit or electrical outlet
capacity is not known.
Utility Interruption of
Charging
For participating customers using
AC charging, this vehicle will
respond to remote requests via OnStar to limit or completely block
electrical power grid usage for brief
time periods. A utility interruption of
charging may increase AC vehicle
charge times, but will not affect DC
charge times.
When electrical grid power is
completely blocked, the vehicle will
delay charging until the utility
interruption has expired. The vehicle
should be left plugged in so that,
when the utility interruption expires,
the vehicle can automatically begin
charging.
Changing the charge mode to
Immediate or performing a delayed
charging override will not disable a
utility interruption.
A pop-up will appear in the center
stack display during the key cycle
following any utility interruption. See
“Charging Override/Interruption
Pop-up”
underProgrammable
Charging on page 5-31. Text will be displayed on the
instrument cluster indicating that a
utility interruption has occurred. See
Instrument Cluster on page 5-9.
