Additional Factors Affecting System
Operation
Safety belts help keep the passenger in position on theseat during vehicle maneuvers and braking, whichhelps the passenger sensing system maintain thepassenger airbag status. See “Safety Belts” and“Child Restraints” in the Index for additional informationabout the importance of proper restraint use.
A thick layer of additional material, such as a blanket orcushion, or aftermarket equipment such as seatcovers, seat heaters, and seat massagers can affecthow well the passenger sensing system operates.We recommend that you not use seat covers or otheraftermarket equipment except when approved by GM foryour specific vehicle. SeeAdding Equipment to YourAirbag-Equipped Vehicle on page 2-73for moreinformation about modifications that can affect how thesystem 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 placesaround the vehicle. Your dealer/retailer and theservice manual have information about servicing thevehicle and the airbag system. To purchase a servicemanual, seeService Publications Ordering Informationon page 8-17.
{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 changeabout the vehicle that could keep the airbagsfrom working properly?
A:Yes. If you add things that change your 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, overhead console, front
sensors, side impact sensors, or airbag wiring can
affect the operation of the airbag system.
In addition, your vehicle has a passenger sensing
system for the right front passenger’s position,
which includes sensors that are part of the
passenger’s 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 2-67.
If you have any questions about this, you should
contact Customer Assistance before you modify
your vehicle. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this manual.

Q:Because I have a disability, I have to getmy vehicle modified. How can I find out whetherthis 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 manualhave information about the location of the airbagsensors, sensing and diagnostic module andairbag wiring.

Engine Coolant Heater
The engine coolant heater can provide easier startingand better fuel economy during engine warm-up in coldweather conditions at or below 0°F (!18°C). Vehicleswith an engine coolant heater should be pluggedin at least four hours before starting.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver sideof the engine, behind the transmission dipstick/fluidfill location and next to the engine.
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 andstore the cord as it was before to keep it awayfrom moving engine parts and prevent damage.
The length of time the heater should remain plugged independs on several factors. Ask a dealer/retailer inthe area where you will be parking the vehicle for thebest advice on this.

{WARNING:
An electric engine cooling fan 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.
{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®cancause premature engine, heater core, or radiatorcorrosion. In addition, the engine coolant couldrequire changing sooner, at 50 000 km (30,000 miles)or 24 months, whichever occurs first. Any repairswould not be covered by the vehicle warranty.Always use DEX-COOL®(silicate-free) coolant inthe vehicle.
Engine Coolant
The cooling system in the vehicle is filled withDEX-COOL®engine coolant. This coolant is designedto 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 tocheck and add coolant when it is low. If there is aproblem with engine overheating, seeEngineOverheating on page 6-27.
6-23
Page 344 of 480

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 andDEX-COOL®coolant. If using this mixture, nothing elseneeds 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, theengine could overheat and be badly damaged.The repair cost would not be covered by the vehiclewarranty. Too much water in the mixture canfreeze and crack the engine, radiator, heater core,and other parts.
Notice:If extra inhibitors and/or additives are usedin the vehicle’s cooling system, the vehicle couldbe damaged. Use only the proper mixture ofthe engine coolant listed in this manual for thecooling system. SeeRecommended Fluids andLubricants on page 7-8for more information.

If No Steam Is Coming From The
Engine Compartment
If an engine overheat warning is displayed but no steamcan be seen or heard, the problem may not be tooserious. Sometimes the engine can get a little too hotwhen the vehicle:
•Climbs a long hill on a hot day.
•Stops after high-speed driving.
•Idles for long periods in traffic.
•Tows a trailer.
If the overheat warning is displayed with no sign ofsteam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature andto the highest fan speed. Open the windows asnecessary.
3. In heavy traffic, let the engine idle in N (Neutral) whilestopped. If it safe to do so, pull off the road, shift toP (Park) or N (Neutral) and let the engine idle.
If the temperature overheat gage is no longer in theoverheat zone or an overheat warning no longer displays,the vehicle can be driven. Continue to drive the vehicleslow for about 10 minutes. Keep a safe vehicle distancefrom the car in front of you. If the warning does not comeback on, continue to drive normally.
If the warning continues, pull over, stop, and park thevehicle right away.
If there is no sign of steam, idle the engine for threeminutes while parked. If the warning is still displayed, turnoff the engine until it cools down. Also, see!OverheatedEngine Protection Operating Mode!next in this section.
Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and themessage ENGINE OVERHEATED STOP ENGINE isdisplayed, an overheat protection mode which alternatesfiring groups of cylinders helps prevent engine damage.In this mode, you will notice a loss in power andengine performance. This operating mode allows yourvehicle to be driven to a safe place in an emergency.Driving extended miles (km) and/or towing a trailer in theoverheat protection mode should be avoided.
Notice:After driving in the overheated engineprotection operating mode, to avoid engine damage,allow the engine to cool before attempting anyrepair. The engine oil will be severely degraded.Repair the cause of coolant loss, change the oil andreset the oil life system. SeeEngine Oil onpage 6-13.
