especially with the windows
closed in warm or hot weather.
They can be overcome by the
extreme heat and suffer
permanent injuries or even death
from heat stroke.
The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when either rear
window is down and the front
windows are up. To reduce the
sound, open either a front window
or the sunroof, if equipped.

Heated and Ventilated
Front Seats
{Warning
If you cannot feel temperature
change or pain to the skin, the
seat heater may cause burns. 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.

3-10 Seats and Restraints
Heated and Ventilated Seat
Buttons Shown, Heated Seat Buttons Similar
If equipped, the buttons are part of
the climate control system on the
center stack. To operate, the ignition
and the climate control system must
be on. If the climate control system
is off, press the
Obutton to turn

seat. The air is not cooled.
Press the button once for the
highest setting. With each press of
the button, the seat will change to
the next lower setting, and then to
the off setting. The lights near the
heated or ventilated seat symbol on
the display indicate three for the
highest setting and one for the
lowest.
If the heated seats are on high, the
level may automatically lower after
approximately 30 minutes.
The passenger seat may take
longer to heat up.
Remote Start Auto Heated and
Ventilated Seats
During a remote start, the heated or
ventilated seats, if equipped, can be
turned on automatically. When it is
cold outside, the heated seats turn
on, and when it is hot outside the ventilated seats turn on. The heated
or ventilated seats are canceled
when the ignition is turned on. Press
the button to use the heated or
ventilated seats after the vehicle is
started.
The heated or ventilated seat
indicator lights on the button do not
turn on during a remote start.
The heated seat temperature
performance of an unoccupied seat
may be reduced. This is normal.
The heated or ventilated seats will
not turn on during a remote start
unless they are enabled in the
vehicle personalization menu. See

Seats and Restraints 3-29
If the On Indicator Is Lit for a
Child Restraint
The passenger sensing system is
designed to turn off the front
outboard passenger frontal airbag if
the system determines that an infant
is present in 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 fromthe 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 3-49 orSecuring
Child Restraints (Front
Passenger Seat) on page 3-51. 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 airbag for a
child in a child restraint depending
upon the child's size. It is better to
secure the child restraint in a
rear seat.
If the Off Indicator Is Lit for an
Adult-Sized Occupant
If a person of adult-size is sitting in
the front outboard passenger seat,
but the off indicator is lit, it could be
because that person is not sitting
properly in the seat. Use the
following steps to allow the system
to detect that person and enable the
front outboard passenger frontal
airbag:
1. Turn the vehicle off.

3-30 Seats and Restraints
2. Remove any additional materialfrom the seat, such as blankets,
cushions, seat covers, seat
heaters, seat massagers, a
laptop, or other electronic
devices.
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.
{Warning
If the front outboard passenger
airbag is turned off for an
adult-sized occupant, the airbag
will not be able to inflate and help
protect that person in a crash,
resulting in an increased risk of
(Continued)
Warning (Continued)
serious injury or even death. An
adult-sized occupant should not
ride in the front outboard
passenger seat, if the passenger
airbag off 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. See
Adding Equipment to
the Airbag-Equipped Vehicle on
page 3-31 for more information
about modifications that can affect
how the system operates.
A wet seat can affect the
performance of the passenger
sensing system. Here is how:.The passenger sensing system
may turn off the passenger
frontal airbag when liquid is
soaked into the seat. If this
happens, the off indicator will be
lit, and the airbag readiness light
on the instrument cluster will
also be lit.
.Liquid pooled on the seat that
has not soaked in may make it
more likely that the passenger
sensing system will turn on the
passenger frontal airbag while a
child restraint or child occupant
