The passenger sensing systemturns off the front outboardpassenger frontal airbag undercertain conditions. No other airbagis affected by the passengersensing system.
The passenger sensing systemworks with sensors that are part ofthe front outboard passenger seatand safety belt. The sensors aredesigned to detect the presence ofaproperlyseatedoccupantanddetermine if the front outboardpassenger frontal airbag should beallowed to inflate or not.
According to accident statistics,children are safer when properlysecured in a rear seat in the correctchild restraint for their weightand size.
Whenever possible, children aged12 and under should be secured inarearseatingposition.
Never put a rear-facing child seat inthe front. This is because the risk tothe rear-facing child is so great,if the airbag deploys.
{Warning
Achildinarear-facingchild
restraint can be seriously injured
or killed if the passenger frontal
airbag inflates. This is because
the back of the rear-facing child
restraint would be very close to
the inflating airbag. A child in a
forward-facing child restraint can
be seriously injured or killed if the
passenger frontal airbag inflates
and the passenger seat is in a
forward position.
Even if the passenger sensing
system has turned off the
passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag is turned off.
Never put a rear-facing child
restraint in the front seat, even if
the airbag is off. If securing a
forward-facing child restraint in

the front outboard passenger
seat, always move the seat as far
back as it will go. It is better to
secure child restraints in the rear
seat. Consider using another
vehicle to transport the child
when a rear seat is not available.
If the vehicle does not have a rearseat that will accommodate arear-facing child restraint, arear-facing child restraint should notbe installed in the vehicle, even ifthe airbag is off.
The passenger sensing system isdesigned to turn off the frontoutboard passenger frontal airbag if:
.The front outboard passengerseat is unoccupied.
.The system determines an infantis present in a child restraint.
.Afrontoutboardpassengertakes his/her weight off of theseat for a period of time.

{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 thevehicle's frame, bumper system,height, front end, or side sheetmetal, may keep the airbag systemfrom working properly. Theoperation of the airbag system canalso be affected by changing anyparts of the front seats, safety belts,the airbag sensing and diagnosticmodule, steering wheel, instrumentpanel, any of the airbag modules,
ceiling headliner or pillar garnishtrim, overhead console, frontsensors, side impact sensors,or airbag wiring.
Yo u r d e a l e r a n d t h e s e r v i c e m a n u a lhave information about the locationof the airbag sensors, sensing anddiagnostic module, and airbagwiring.
In addition, the vehicle may have apassenger sensing system for thefront outboard passenger position,which includes sensors that are partof the passenger seat. Thepassenger sensing system may notoperate properly if the original seattrim is replaced with non-GMcovers, upholstery, or trim; or withGM covers, upholstery, or trimdesigned for a different vehicle. Anyobject, such as an aftermarket seatheater or a comfort-enhancing pador device, installed under or on topof the seat fabric, could alsointerfere with the operation of thepassenger sensing system. Thiscould either prevent properdeployment of the passengerairbag(s) or prevent the passengersensing system from properly
turning off the passenger airbag(s).SeePassenger SensingSystem082.
If the vehicle has rollover roof-railairbags, seeDifferent Size Tiresand Wheels0416for additionalimportant information.
If a snow plow is added to thevehicle, the airbags should still workproperly. The airbag systems weredesigned to work properly under awide range of conditions, includingsnow plowing with vehicles thathave the optional snow plow preppackage (RPO VYU). Do notchange or defeat the snow plow's“tripping mechanism.”If you do, itcan damage the snow plow and thevehicle, and may cause an airbagdeployment.
If you have to modify your vehiclebecause you have a disability andyou have questions about whetherthe modifications will affect thevehicle's airbag system, or if youhave questions about whether theairbag system will be affected if thevehicle is modified for any other

7. Before placing a child in thechild restraint, make sure it issecurely held in place. Tocheck, grasp the child restraintat the safety belt path andattempt to move it side to sideand back and forth. When thechild restraint is properlyinstalled, there should be nomore than 2.5 cm (1 in) ofmovement.
To r e m o v e t h e c h i l d r e s t r a i n t ,unbuckle the vehicle safety belt andlet it return to the stowed position.If the top tether is attached to a toptether anchor, disconnect it.
For outboard rear seating positions,if the child restraint cannot beinstalled properly with the headrestin place, the headrest may be
removed. See your dealer forassistance with removal, and storethe removed headrest in a secureplace. When the child restraint isremoved, reinstall the headrestbefore the seating position is used.For reinstallation instructions, see“Headrest Removal andReinstallation”underLower Anchorsand Tethers for Children (LATCHSystem)096.

Voltmeter Gauge
When the ignition is on, this gaugeindicates the battery voltage.
When the engine is running, thisgauge shows the condition of thecharging system. The gauge cantransition from a higher to lower or alower to higher reading. This isnormal. If the vehicle is operatingoutside the normal operating range,the charging system light comes on.SeeCharging System Light0138for more information. The voltmetergauge may also read lower when infuel economy mode. This is normal.
Readings outside the normaloperating range can also occurwhen a large number of electricalaccessories are operating in thevehicle and the engine is left idlingfor an extended period. Thiscondition is normal since thecharging system is not able toprovide full power at engine idle. Asengine speeds are increased, thiscondition should correct itself ashigher engine speeds allow thecharging system to create maximumpower.
The vehicle can only be driven for ashort time with the readings outsidethe normal operating range. If thevehicle must be driven, turn off allaccessories, such as the radio andair conditioner.
Readings outside the normaloperating range indicate a possibleproblem in the electrical system.Have the vehicle serviced as soonas possible.
