62 SEATS AND RESTRAINTS
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 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 (With the Seat Belt in the
Rear Seat) 079 or
Securing Child Restraints (With the
Seat Belt in the Front Seat) 081.
Make sure the seat belt retractor is
locked by pulling the shoulder belt
all the way out of the retractor
when installing the child restraint,
even if the child restraint is
equipped with a seat belt lock off.
When the retractor lock is set, the
belt can be tightened but not
pulled out of the retractor. 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 037.
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. Never
put a rear-facing child restraint in the
front seat, even if the ON indicator is
not lit.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 or that the child
restraint locking feature is engaged.
Use the following steps to allow the
system to detect that person and
enable the front outboard passenger
frontal airbag and knee airbag: 1. Turn the vehicle off.

2. Remove any additional materialfrom 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. If the shoulder portion of the belt is pulled out all the way, the child
restraint locking feature will be
engaged. This may unintentionally
cause the passenger sensing system
to turn the airbag off for some
adult-sized occupants. If this
happens, unbuckle the belt, let the
belt go back all the way, and then
buckle the belt again without
pulling the belt out all the way.
6. 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
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
Seat 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 “Seat 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 064 for
more information about modifications
that can affect how the system
operates.
The ON indicator may be lit if an
object, such as a briefcase, handbag,
grocery bag, laptop, or other electronic
device, is put on an unoccupied seat.
If this is not desired, remove the
object from the seat.{Warning
Stowing articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.

Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle should
be serviced. There are parts of the
airbag system in several places around
the vehicle. Your dealer and the
service manual have information
about servicing the vehicle and the
airbag system. To purchase a service
manual, seePublication Ordering
Information 0393.
{Warning
For up to 10 seconds after the
vehicle is turned off and the 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,
including improperly repairing or
replacing, any parts of the following:
.Airbag system, including airbag
modules, front or side impact
sensors, sensing and diagnostic
module, or airbag wiring
.Front seats, including stitching,
seams or zippers
.Seat belts
.Steering wheel, instrument panel,
overhead console, ceiling trim,
or pillar garnish trim
.Inner door seals, including speakers
Your dealer and the service manual
have information about the location of
the airbag modules and sensors, sensing and diagnostic module, and
airbag wiring along with the proper
replacement procedures.
In addition, the vehicle has a
passenger sensing system for the front
outboard 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
passenger airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). See
Passenger Sensing
System 060.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires and
Wheels 0335 for additional important
information.

222 DRIVING AND OPERATING
Auto Stop Disable Switch
The automatic engine Stop/Start
feature can be disabled and enabled
by pressing
h. Auto Stop/Start is
enabled each time you start the
vehicle.
When the
hindicator is illuminated,
the system is enabled.
Winter Cover
If equipped, the winter cover can be
used to enhance heater performance
in extremely cold conditions below
−0 °C (32 °F). The winter cover installs
over the grille and restricts airflow to
the engine compartment.
Usage Guidelines
The winter cover should only be used
while operating the vehicle in
extremely cold temperatures or in
heavy snow for extended periods. In
these temperatures, the vehicle does
not need a large amount of air to
properly cool the engine. When more
airf low is required to cool the vehicle,
the winter cover should not be used.
The following usage guidelines will
allow adequate airf low for proper
radiator and air cooler performance:
.Do not use the winter cover if
towing a trailer. The vehicle may
overheat if the radiator is covered
while towing.
.Do not modify the cover. The winter
cover does not cover some sections
of the front of the vehicle to provide
enough airflow.
.Keep the underside of the winter
cover as clean as possible. Remove
monthly or as necessary and clean
away dust and debris.
.Do not use the winter cover above
−0 °C (32 °F). Use only a mild soap to clean. Do not
use harsh soap, strong detergents,
or vinyl protectant/sealant type
products as they may damage the
special finish. Allow the winter cover
to dry completely before reinstalling.
Installation Instructions
When first trying to fit the cover, it
may appear to be undersized but will
stretch during installation to ensure a
tight fit. The initial installation of the
cover is best performed when the
winter cover is warm.
1. Center grille cover and make sure
that it is positioned correctly.

2. Push plastic hooks back to engagegrille slats. It is recommended to
start with the lower hooks at the
center of the grille.
3. Repeat for all hooks to fully engage cover to grille.
For vehicles equipped with a front
license plate bracket, only the outer
clips will be engaged on the upper
row. Ensure the top center portion
of the cover is positioned securely
behind the license plate bracket.
4. Make sure all clips remain engaged during installation. Cover should be
stretched to a tight fit when
properly installed.
Engine Heater
The engine heater, if available, can
help in cold weather conditions at or
below −18 °C (0 °F) for easier starting
and better fuel economy during
engine warm-up. Plug in the engine
heater at least four hours before
starting the vehicle. An internal
thermostat in the plug end of the cord
will prevent engine heater operation
at temperatures above −18 °C (0 °F).
{Warning
Do not plug in the engine block
heater while the vehicle is parked in
a garage or under a carport.
Property damage or personal injury
may result. Always park the vehicle
in a clear open area away from
buildings or structures.
To Use the Engine Heater

{Warning
Improper use of the heater cord or
an extension cord can damage the
cord and may result in overheating
and fire.
.Plug the cord into a three-prong
electrical utility receptacle that is
protected by a ground fault
detection function. An
ungrounded outlet could cause
an electric shock.
.Use a weatherproof, heavy-duty,
15 amp-rated extension cord if
needed. Failure to use the
recommended extension cord in
good operating condition,
or using a damaged heater or
extension cord, could make it
overheat and cause a fire,
property damage, electric shock,
and injury.
.Do not operate the vehicle with
the heater cord permanently
attached to the vehicle. Possible
heater cord and thermostat
damage could occur.(Continued)
Warning (Continued)
.While in use, do not let the
heater cord touch vehicle parts
or sharp edges. Never close the
hood on the heater cord.
.Before starting the vehicle,
unplug the cord, reattach the
cover to the plug, and securely
fasten the cord. Keep the cord
away from any moving parts.
4. Before starting the engine, be sure to unplug and store the cord as it
was before to keep it away from
moving engine parts. If you do not
it could be damaged.
The length of time the heater should
remain plugged in depends on several
factors. Ask a dealer in the area where
you will be parking the vehicle for the
best advice on this.
