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 toSecuring a Child Restraint in the Right Front
Seat Position on page 2-60.5. 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. SeeHead Restraints
on page 2-8.
6. Restart the vehicle.
If the on indicator is still lit, secure the child in
the child restraint in a rear seat position in
the vehicle and check with your dealer/retailer.
If no rear seat is available, do not install a child
restraint in this vehicle and check with your
dealer/retailer.

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 the
system to detect that person and enable the right front
passenger frontal 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.
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
2-78

system to turn the airbag off for some adult size
occupants. If this happens, let the belt go back all the
way and start again.
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. SeeAdding Equipment to Your Airbag-Equipped
Vehicle on page 2-80for more information about
modifications that can affect how the system operates.
{WARNING:
Stowing of 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 Your 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/retailer and the
service manual have information about servicing the
vehicle and the airbag system. To purchase a service
manual, seeService Publications Ordering Information
on page 8-15.
{WARNING:
For up to 10 seconds after the ignition 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 Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change the vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, front sensors, or airbag wiring
can affect the operation of the airbag system.
In addition, the vehicle may have 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 passenger airbag(s) or prevent the passenger
sensing system from properly turning off the
passenger airbag(s). SeePassenger Sensing
System on page 2-73.

Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out whether
this will affect my airbag system?
A:If you have questions, call Customer Assistance.
The phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual. See
Customer Satisfaction Procedure on page 8-2.
In addition, your dealer/retailer and the service manual

Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicles
with an engine coolant heater should be plugged
in at least four hours before starting. An internal
thermostat in the plug-end of the cord may exist
which will prevent engine coolant heater operation at
temperatures above 0° F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the engine compartment
behind the underhood fuse block on the driver side
of the vehicle.
3. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
You could be seriously injured. Plug the cord
into a properly grounded three-prong 110-volt
AC outlet. If the cord will not reach, use a
heavy-duty three-prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord to prevent damage.
The length of time the heater should remain plugged in
depends on several factors. Ask a dealer/retailer in
the area where you will be parking the vehicle for the
best advice on this.

{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 engine 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.
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 miles)
or 24 months, whichever occurs rst. Any repairs
would not be covered by the vehicle warranty.
Always use DEX-COOL
®(silicate-free) coolant
in the vehicle.
Engine Coolant
The cooling system in the vehicle is filled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for five years or 150,000 miles
(240 000 km), whichever occurs first.
The following explains the cooling system and how
to check and add coolant when it is low. If there
is a problem with engine overheating, seeEngine
Overheating on page 6-35.
6-29

What to Use
{WARNING:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper coolant
mixture will. The vehicle’s coolant warning system
is set for the proper coolant mixture. With plain
water or the wrong mixture, the engine could get
too hot but you would not get the overheat
warning. The engine could catch fire and you or
others could be burned. Use a 50/50 mixture of
clean, drinkable water and DEX-COOL
®coolant.
Use a 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant. If using this mixture, nothing
else needs to be added. This mixture:
•Gives freezing protection down to−34°F (−37°C),
outside temperature.
•Gives boiling protection up to 265°F (129°C),
engine temperature.
•Protects against rust and corrosion.
•Will not damage aluminum parts.
•Helps keep the proper engine temperature.
Notice:If an improper coolant mixture is used,
the engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and other
parts.
Notice:If extra inhibitors and/or additives are used
in the vehicle’s cooling system, the vehicle could
be damaged. Use only the proper mixture of
the engine coolant listed in this manual for the
cooling system. SeeRecommended Fluids and
Lubricants on page 7-10for more information.
