1-26 In Brief
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.
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.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. Maintenance
Always keep the tires properly
inflated and the vehicle properly
aligned.
The weight of excess cargo in the
vehicle affects efficiency and range.
Avoid carrying more than is needed.
If fuel is not regularly used, consider
keeping the fuel tank only one‐third
full. Excess fuel weight impacts
efficiency and range.
Use premium fuel.
Avoid unnecessary use of electrical
accessories. Power used for
functions other than propelling the
vehicle will reduce EV range.
Using a rooftop carrier will reduce
efficiency due to additional weight
and drag.

{WARNING
If you cannot feel temperature
change or pain to the skin, the
seat heater may cause burns
even at low temperatures.
To reduce the risk of burns,
people with such a condition
should use care when using
the seat heater, especially for
long periods of time. Do not
place anything on the seat that
insulates against heat, such
as a blanket, cushion, cover,
or similar item. This may cause
the seat heater to overheat.
An overheated seat heater may
cause a burn or may damage
the seat.
If available, the controls are on the

Seats and Restraints 3-35
For some children, including
children in child restraints,
and for very small adults, the
passenger sensing system may
or may not turn off the right front
passenger frontal airbag and
passenger knee airbag, depending
upon the person’s seating posture
and body build. Everyone in the
vehicle who has outgrown child
restraints should wear a safety
belt properly —whether or not
there is an airbag for that person.
{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. See Airbag Readiness
Light on page 5‑19 for more
information, including important
safety information.
If the On Indicator is Lit for a
Child Restraint
If a child restraint has been installed
and the on indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
4. Reinstall the child restraint following the directions
provided by the child restraint
manufacturer and refer to
Securing Child Restraints
(Rear Seat) on page 3‑57 or
Securing Child Restraints (Front
Passenger Seat) on page 3‑60. 5. If, after reinstalling the child
restraint and restarting the
vehicle, the on indicator is
still lit, turn the vehicle off.
Then slightly recline the vehicle
seatback and adjust the seat
cushion, if adjustable, to make
sure that the vehicle seatback
is not pushing the child restraint
into the seat cushion.
Also make sure the child
restraint is not trapped under
the vehicle head restraint.
If this happens, adjust the head
restraint. See Head Restraints
on page 3‑2.
6. Restart the vehicle.
The passenger sensing system
may or may not turn off the
airbags for a child in a child
restraint depending upon the
child's seating posture and body
build. It is better to secure a
child restraint in a rear seat.

3-36 Seats and Restraints
If the Off Indicator is Lit for an
Adult-Size Occupant
If a person of adult size is sitting
in the right front passenger seat,
but the off indicator is lit, it could be
because that person is not sitting
properly in the seat. If this happens,
use the following steps to allow thesystem to detect that person and
enable the right front passenger
frontal airbag and passenger
knee airbag:
1. Turn the vehicle off.
2. Remove any additional material
from the seat, such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat, centered on the seat
cushion, with legs comfortably
extended.
5. Restart the vehicle and have the person remain in this position for
two to three minutes after the on
indicator is lit.
Additional Factors Affecting
System Operation
Safety belts help keep the
passenger in position on the
seat during vehicle maneuvers
and braking, which helps the
passenger sensing system maintain
the passenger airbag status.
See “Safety Belts” and“Child
Restraints” in the Index for
additional information about the
importance of proper restraint use.
A thick layer of additional material,
such as a blanket or cushion,
or aftermarket equipment such
as seat covers, seat heaters,
and seat massagers can affect
how well the passenger sensing
system operates. We recommend
that you not use seat covers or
other aftermarket equipment
except when approved by GM
for your specific vehicle.

Seats and Restraints 3-39
In addition, the vehicle has a
passenger sensing system
for the right front passenger
position, which includes sensors
that are part of the passenger
seat. The passenger sensing
system may not operate properly
if the original seat trim is
replaced with non-GM covers,
upholstery or trim, or with
GM covers, upholstery or
trim designed for a different
vehicle. Any object, such as
an aftermarket seat heater
or a comfort enhancing pad
or device, installed under or on
top of the seat fabric, could also
interfere with the operation of
the passenger sensing system.
This could either prevent proper
deployment of the passengerairbag(s) or prevent the
passenger sensing system
from properly turning off
the passenger airbag(s).

Climate Controls 8-5
Air Conditioning/Heat StatusIndicators
The air conditioning/heat status
displays when the air conditioning
or electric heat is being used.
The air conditioning and electric
heat could be on at the same time
when dehumidification is required
in ECO or Comfort modes.
In Fan Only mode, occasionally
the air conditioning and/or heating
status will be on if the Auto Defog
function is enabled and high
humidity is detected. See “Climate
and Air Quality” underVehicle
Personalization on page 5‑53,
for details on enabling or disabling
the Auto Defog function. The air conditioning may also run
if
0is selected, regardless of the
climate mode.
Automatic Operation
The system automatically controls
the fan speed, air delivery mode,
and recirculation to heat or cool the
vehicle to the selected temperature.
When the AUTO indicator light is

Auto Defog: The system will
monitor high humidity inside the
vehicle. When high humidity is
detected, the climate control system
may adjust to outside air supply and
turn on the air conditioner or the
heater. The fan speed may slightly
increase to help prevent fogging.
When high humidity is no longer
detected, the system will return
to its prior operation. To turn Auto

Driving and Operating 9-3
Drive Mode and PRNDL Selection
Use Normal Mode when possible.
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 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.
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.
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.

10-18 Vehicle Care
Cooling System (Engine)
When it is safe to lift the hood:
A. Engine Coolant Surge Tank andPressure Cap
B. Engine Cooling Fans (Out of View)
{WARNING
The electric cooling fans under
the hood can start up even when
the engine is not running and
can cause injury. Keep hands,
clothing, and tools away from
any underhood electric fan. If the coolant inside the coolant
surge tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on
a level surface.
The coolant level should be up to
the cold fill line. If it is not, there
might be a leak at the radiator
hoses, heater hoses, radiator,
water pump, or somewhere else
in the cooling system.
{WARNING
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the vehicle if there
is a leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
If there seems to be no leak,
with the engine on, check to
see if the electric engine cooling
fans are running. If the engine is
overheating, the fans should be
running. If it is not, the vehicle
needs service. Turn off the vehicle.
Notice:
Using coolant other than
DEX-COOL
®can cause premature
engine, heater core, or radiator
corrosion. In addition, the engine
coolant could require changing
sooner, at 50 000 km (30,000 mi)
or 24 months, whichever occurs
first. Any repairs would not
be covered by the vehicle
warranty. Always use DEX-COOL
(silicate-free) coolant in the
vehicle.

Vehicle Care 10-19
Cooling System
(High Voltage Battery)
During vehicle operation and
also during charging, the high
voltage battery cells in the
vehicle are kept within a normal
operating temperature range.
If the temperature rises above this
temperature, the battery cooling
system turns on the air conditioning
compressor and cools the coolant
until the correct temperature is
reached. If the temperature falls
below this temperature, a high
voltage heater, located in the
battery, heats the coolant until the
correct temperature is reached.
What to Use
The high voltage battery coolant
reservoir in the vehicle is filled
with a 50/50 mixture of DEX-COOL
engine coolant and deionized water.
If using this mixture, nothing else
needs to be added.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
The high voltage battery
coolant reservoir is located
on the passenger side of the
engine compartment. SeeEngine
Compartment Overview on
page 10‑10 for more information
on location.Check to see if coolant is visible
in the high voltage battery coolant
reservoir. If coolant is visible but the
coolant level is below the cold fill
line, there could be a leak in the
cooling system.
The high voltage battery coolant
should only be serviced by a
qualified technician.
