Charging Override/Interruption
Pop-Up
The Charging Override/Interruption
pop-up will appear if any of the
following conditions occur:
.The charging settings have been
modified via OnStar through the
website or the Mobile App. For
example, the Departure Time
Tables, the Rate Tables, or the
Charge Mode were updated
using the customer website
(available in select regions).
.There was an unintended loss of
AC power during the plug-in
charge event. For example,
there was a power outage or the
charge cord was unplugged from
the wall.
.The charge process was
interrupted by the utility
company via OnStar as
authorized by the vehicle owner
(available in select regions).

Sport Mode provides more
responsive acceleration than
Normal Mode but can reduce
efficiency.
Use Mountain Mode prior to
climbing long, steep grades in
mountainous areas. Be sure to
engage Mountain Mode before
starting to climb. Mountain Mode
reduces electric range and power
but may be needed to maintain
speeds above 96 km/h (60 mph)
when climbing grades of 5% or
greater.
Use Hold Mode on a trip where all
or most of the electric charge will be
depleted. Use Hold Mode mainly
during highway or high speed
driving to maximize both EV miles
and fuel efficiency.
Use L (Low) in heavy stop-and-go
traffic or when traveling downhill.
L (Low) requires less brake pedal
application and provides a
controlled, efficient way to slow the
vehicle down.Climate Setting
Using the heat and air conditioning
systems decreases the energy
available for electric driving.
Optimal energy efficiency is
achieved with the heat, air
conditioning, and fan turned off.
Less energy is used at low fan
speeds. When using the fan:
.Fan Only is the most energy
efficient climate setting as long
as
0is not selected.
.ECO is for moderate air
conditioning and heater
operation and is the next most
energy efficient setting as long
as
0is not selected.
.Comfort provides the most
comfort but is the least energy
efficient.
Use the auto heated seat feature
instead of climate settings. Heating
the seat uses less energy than
heating the vehicle interior. Use remote start to heat or cool the
interior when the vehicle is plugged
in to maximize the electric range by
utilizing electricity from the electrical
outlet.
Engine Assisted Heating operation,
if equipped, can be personalized.
In hot weather, avoid parking in
direct sunlight or use sunshades
inside the vehicle.
Turn off the front and rear window
defog/defrost when they are no
longer needed.
Avoid driving with the windows open
at highway speeds.
See
Vehicle Personalization on
page 5-50.Vehicle Charging/Maintenance
Charging
Keep the vehicle plugged in, even
when fully charged, to keep the
battery temperature ready for the
next drive. This is important when
outside temperatures are extremely
hot or cold.

electric drive unit to be locked in
P (Park) until the propulsion system
has warmed sufficiently.
The shift lock is always functional
except in the case of an uncharged
or low charged 12-volt battery (less
than 9 volts).
If the vehicle has an uncharged
12-volt battery or a 12-volt battery
with low voltage, try charging or
jump starting the 12-volt battery.
SeeBattery on page 10-23 orJump
Starting on page 10-69.
If the console shift lever cannot be
moved out of P (Park):
1. Apply and maintain the regular brakes.
2. Turn the vehicle on using the POWER
Obutton. See Power
Button on page 9-16.
3. Let up on the shift lever and make sure the shift lever is
pushed all the way into P (Park).
4. Press the shift lever button. 5. Move the shift lever into the
desired gear.
If you still cannot move the shift
lever from P (Park), see your dealer
or a professional towing service.
Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.
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.

If LDW is on,@is green if LDW is
available to warn of a lane
departure. If the vehicle crosses a
detected lane marking without using
the turn signal in that direction,
@
changes to amber and flashes.
Additionally, there will be three
beeps on the right or left, depending
on the lane departure direction.
When the System Does Not
Seem To Work Properly
The system may not detect lanes as
well when there are:
.Close vehicles ahead.
.Sudden lighting changes, such
as when driving through tunnels.
.Banked roads. If the LDW system is not functioning
properly when lane markings are
clearly visible, cleaning the
windshield may help.
LDW alerts may occur due to tar
marks, shadows, cracks in the road,
temporary or construction lane
markings, or other road
imperfections. This is normal system
operation; the vehicle does not need
service. Turn LDW off if these
conditions continue.
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 5-28.
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
Start Charge
1. Make sure the vehicle is parkedand turned off.
2. Push the rearward edge of the charge port door in and release
to open the door.
In cold weather conditions, ice
may form around the charge port
door. Remove ice from the area
before attempting to open or
close the charge port door.
3. Open the rear hatch, lift the loadsupport floor covering, and
remove the charge cord. It is
near the tire sealant and
compressor kit. Pull up on the
charge cord handle. The vehicle
plug is stored as shown. 4. Plug the charge cord into the
electrical outlet. See Electrical
Requirements for Battery
Charging on page 9-52. Verify
the charge cord status. See
Charge Cord on page 9-51 and
the charge cord user guide.
Select the appropriate charge
level using the Select Charge
Level Preference screen on the
center stack. See “Charge Level
Selection” underProgrammable
Charging on page 5-28.
