In Brief 27
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.
. Use eco for moderate air
conditioning and heater
operation. This is the next most
energy efficient setting as long
as
0is not selected.
. MAX provides the most comfort
but is the least energy efficient.
Use the auto heated seat feature
and the heated steering wheel
instead of climate settings. Heating
the seat and steering wheel 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,
if equipped, can be personalized
while plugged in. See
“Engine
Assist Heat Plugged In” under
Vehicle Personalization 0141.
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.
For fuel recommendations, see
Fuel
0230.
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.

cool the interior when the vehicle is
plugged in to maximize the electric
range by utilizing electricity from the
electrical outlet. Normal operation of
the system will return after the
vehicle has been turned on.
/:This button is on the RKE
transmitter.
During remote start:
. The climate control system will
typically default to the last
climate setting. If the fan is off or
if eco and MAX are not selected,
the air conditioning or heat will
turn on as needed. See
Automatic Climate Control
System 0157.
. If equipped with heated seats,
and the vehicle personalization
setting is enabled, the remote
start auto heated seats may also
come on. See Heated Front
Seats 054, and Vehicle
Personalization 0141.
. If equipped the heated steering
wheel may also come on. See
Heated Steering Wheel 096. .
The rear window defogger will
turn on during colder outside
temperatures.
. Selecting
1during colder
outside temperatures before
shutting the vehicle off will help
windshield clearing.
. Shutting the vehicle off in eco
mode without
1selected will
minimize the impact to electric
range. Shutting the vehicle off in
other modes will maximize
heating or air conditioning.
. The engine may start to provide
energy for heating and cooling,
independent of the vehicle being
plugged in or completely
charged. Engine Assisted
Heating operation, if available,
can be personalized. See
“Engine Assist Heat Plugged In”
under Vehicle
Personalization 0141.
. Vehicle range may decrease if
the vehicle is not plugged into
an electrical outlet. If the vehicle
is plugged in, much of the
energy needed to support this feature will be provided from the
electrical outlet, not from the
high voltage battery.
Laws in some communities may
restrict the use of features that
remotely start the engine. For
example, some laws may require a
person using the remote start
feature to have the vehicle in view
when doing so. Check local
regulations for any requirements on
remote starting of vehicles.
The RKE transmitter range may be
less while the vehicle is running.
Other conditions can affect the
performance of the transmitter. See
Remote Keyless Entry (RKE)
System 030.

New parts and repairs may be
necessary even if the safety belt
system was not being used at the
time of the crash.
Have the safety belt pretensioners
checked if the vehicle has been in a
crash, or if the airbag readiness light
stays on after you start the vehicle
or while you are driving. SeeAirbag
Readiness Light 0108.Airbag System
The vehicle has the following
airbags:
.
A frontal airbag for the driver.
. A frontal airbag for the front
outboard passenger.
. A knee airbag for the driver.
. A knee airbag for the front
outboard passenger.
. A seat-mounted side impact
airbag for the driver.
. A seat-mounted side impact
airbag for the front outboard
passenger.
. Seat-mounted side impact
airbags for the second row
outboard passengers.
. A roof-rail airbag for the driver
and the passenger seated
directly behind the driver.
. A roof-rail airbag for the front
outboard passenger and the
passenger seated directly
behind the front outboard
passenger. All vehicle airbags have the word
AIRBAG on the trim or on a label
near the deployment opening.
For frontal airbags, the word
AIRBAG is on the center of the
steering wheel for the driver and on
the instrument panel for the front
outboard passenger.
For knee airbags, the word AIRBAG
is on the lower part of the
instrument panel.
For seat-mounted side impact
airbags, the word AIRBAG is on the
side of the seatback closest to
the door.
For roof-rail airbags, the word
AIRBAG is on the ceiling or trim.
Airbags are designed to supplement
the protection provided by safety
belts. Even though today's airbags
are also designed to help reduce
the risk of injury from the force of an
inflating bag, all airbags must inflate
very quickly to do their job.
Here are the most important things
to know about the airbag system:

{Warning
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into
that person causing severe injury
or even death. The path of an
inflating airbag must be kept (Continued)
Warning (Continued)
clear. Do not put anything
between an occupant and an
airbag, and do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering.
Do not use seat accessories that
block the inflation path of a
seat-mounted side impact airbag.
Never secure anything to the roof
of a vehicle with roof-rail airbags
by routing a rope or tie‐down
through any door or window
opening. If you do, the path of an
inflating roof-rail airbag will be
blocked.
When Should an Airbag
Inflate?
This vehicle is equipped with
airbags. SeeAirbag System 063.
Airbags are designed to inflate if the
impact exceeds the specific airbag
system’ s deployment threshold.
Deployment thresholds are used to

How Does an Airbag
Restrain?
In moderate to severe frontal or
near frontal collisions, even belted
occupants can contact the steering
wheel or the instrument panel. In
moderate to severe side collisions,
even belted occupants can contact
the inside of the vehicle.
Airbags supplement the protection
provided by safety belts by
distributing the force of the impact
more evenly over the
occupant's body.
Rollover capable roof-rail airbags
are designed to help contain the
head and chest of occupants in the
outboard seating positions in the
first and second rows. The rollover
capable roof-rail airbags are
designed to help reduce the risk of
full or partial ejection in rollover
events, although no system can
prevent all such ejections.But airbags would not help in many
types of collisions, primarily
because the occupant's motion is
not toward those airbags. See
When
Should an Airbag Inflate? 066.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See after
an Airbag Inflates?
After frontal, knee, and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag inflated.
Roof-rail airbags may still be at least
partially inflated for some time after
they inflate. Some components of
the airbag module may be hot for
several minutes. For location of the
airbags, see Where Are the
Airbags? 065.
The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deflated
airbags. Airbag inflation does not prevent the driver from seeing out of
the windshield or being able to steer
the vehicle, nor does it prevent
people from leaving the vehicle.
{Warning
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon as
it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps, turn on the
hazard warning flashers, and shut
off the fuel system after the airbags

vehicle and the airbag system. To
purchase a service manual, see
Service Publications Ordering
Information0350.
{Warning
For up to 10 seconds after the
vehicle is turned off and the 12‐
volt battery is disconnected, an
airbag can still inflate during
improper service. You can be
injured if you are close to an
airbag when it inflates. Avoid
yellow connectors. They are
probably part of the airbag
system. Be sure to follow proper
service procedures, and make
sure the person performing work
for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet
metal may keep the airbag system
from working properly. The operation of the airbag system
can also be affected by changing
any parts of the front seats, safety
belts, airbag sensing and diagnostic
module, steering wheel, instrument
panel, any of the airbag modules,
ceiling or pillar garnish trim,
overhead console, front sensors,
side impact sensors, rollover sensor
module, or airbag wiring.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
In addition, the vehicle has a
passenger sensing system that
includes sensors as part of the front
outboard 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 thepassenger sensing system. This
could either prevent proper
deployment of the passenger
airbag(s) or prevent the passenger
sensing system from properly
turning off the passenger airbag(s).
See
Passenger Sensing
System 069.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires
and Wheels 0287 for additional
important information.
If you have to modify your vehicle
because you have a disability and
you have questions about whether
the modifications will affect the
vehicle's airbag system, or if you
have questions about whether the
airbag system will be affected if the
vehicle is modified for any other
reason, call Customer Assistance.
