If the On Indicator Is Lit for a
Child Restraint
If a child restraint has been installedand the on indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint fromthe vehicle.
3. Remove any additional itemsfrom the seat such as blankets,cushions, seat covers, seatheaters, or seat massagers.
4. Reinstall the child restraintfollowing the directionsprovided by the child restraintmanufacturer and refer toSecuring Child Restraints (Withthe Safety Belt in the RearSeat)091orSecuring ChildRestraints (With the Safety Beltin the Front Seat)096.
5. If, after reinstalling the childrestraint and restarting thevehicle, the on indicator is stilllit, turn the vehicle off. Thenslightly recline the vehicleseatback and adjust the seatcushion, if adjustable, to makesure that the vehicle seatbackis not pushing the childrestraint into the seat cushion.Also make sure the childrestraint is not trapped underthe vehicle head restraint.If this happens, adjust the headrestraint. SeeHeadRestraints045.
6. Restart the vehicle.
If the on indicator is still lit, securethe child in the child restraint in arear seat position in the vehicle, andcheck with your dealer.
If no rear seat is available, do notinstall a child restraint in this vehicleand check with your dealer.
If the Off Indicator Is Lit for an
Adult-Sized Occupant
If a person of adult-size is sitting inthe front outboard passenger seat,but the off indicator is lit, it could bebecause that person is not sittingproperly in the seat or that the childrestraint locking feature is engaged.Use the following steps to allow thesystem to detect that person andenable the front outboard passengerfrontal airbag:
1. Turn the vehicle off.

2. Remove any additional materialfrom the seat, such asblankets, cushions, seatcovers, seat heaters, or seatmassagers.
3. Place the seatback in the fullyupright position.
4. Have the person sit upright inthe seat, centered on the seatcushion, with legs comfortablyextended.
5. If the shoulder portion of thebelt is pulled out all the way,the child restraint lockingfeature will be engaged. Thismay unintentionally cause thepassenger sensing system toturn the airbag off for someadult-sized occupants. If thishappens, unbuckle the belt, letthe belt go back all the way,and then buckle the belt againwithout pulling the belt out allthe way.
6. Restart the vehicle and havethe person remain in thisposition for two tothree minutes after the onindicator 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
Safety belts help keep thepassenger in position on the seatduring vehicle maneuvers andbraking, which helps the passengersensing system maintain thepassenger airbag status. See“Safety Belts”and“Child Restraints”in the Index for additionalinformation about the importance ofproper restraint use.
Athicklayerofadditionalmaterial,such as a blanket or cushion,or aftermarket equipment such asseat covers, seat heaters, and seatmassagers can affect how well thepassenger sensing systemoperates. We recommend that younot use seat covers or otheraftermarket equipment except whenapproved by GM for your specificvehicle. SeeAdding Equipment tothe Airbag-Equipped Vehicle068for more information aboutmodifications that can affect howthe system operates.
The on indicator may be lit if anobject, such as a briefcase,handbag, grocery bag, laptop,or other electronic device, is put onan unoccupied seat. If this is notdesired remove the object fromthe seat.
{Warning

{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.
Caution
Using coolant other than
DEX-COOL®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner. Any repairs
would not be covered by the
vehicle warranty. Always use
DEX-COOL (silicate-free) coolant
in the vehicle.

Vehicle Care 297
Warning (Continued)
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning isdisplayed but no steam can be seenor heard, the problem may not betoo serious. Sometimes the enginecan get a little too hot when thevehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
If the overheat warning is displayedwith no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to thehighest temperature and to thehighest fan speed. Open thewindows as necessary.
3. When it is safe to do so, pull offthe road, shift to P (Park) orN(Neutral),andlettheengine idle.
If the engine coolant temperaturegauge is no longer in the overheatzone, the vehicle can be driven.Continue to drive the vehicle slowlyfor about 10 minutes. Keep a safedistance from the vehicle in front.If the warning does not come backon, continue to drive normally andhave the cooling system checkedfor proper fill and function.
If the warning continues, pull over,stop, and park the vehicleright away.
If there is no sign of steam, idle theengine for three minutes whileparked. If the warning is stilldisplayed, turn off the engine until itcools down.
Engine Fan
If the vehicle has a clutched enginecooling fan, when the clutch isengaged, the fan spins faster toprovide more air to cool the engine.In most everyday driving conditions,the fan is spinning slower and theclutch is not fully engaged. Thisimproves fuel economy and reducesfan noise. Under heavy vehicleloading, trailer towing, and/or highoutside temperatures, the fan speedincreases as the clutch more fullyengages, so an increase in fannoise may be heard. This is normaland should not be mistaken as thetransmission slipping or makingextra shifts. It is merely the coolingsystem functioning properly. The fanwill slow down when additionalcooling is not required and theclutch disengages.
This fan noise may also be heardwhen starting the engine. It will goaway as the fan clutch partiallydisengages.
If the vehicle has electric coolingfan(s), the fans may be heardspinning at low speed during most
