Seats and Restraints 79
Rollover capable roof-rail airbagsare designed to help contain thehead and chest of occupants in theoutboard seating positions in thefirst and second rows. The rollovercapable roof-rail airbags aredesigned to help reduce the risk offull or partial ejection in rolloverevents, although no system canprevent all such ejections.
But airbags would not help in manytypes of collisions, primarilybecause the occupant's motion isnot toward those airbags. SeeWhenShould an Airbag Inflate?076.
Airbags should never be regardedas anything more than a supplementto safety belts.
What Will You See after
an Airbag Inflates?
For an eAssist vehicle, see theSilverado/Sierra eAssistsupplement.
After the frontal airbags andseat-mounted side impact airbagsinflate, they quickly deflate, soquickly that some people may not
even realize an airbag inflated.Roof-rail airbags may still be at leastpartially inflated for some time afterthey inflate. Some components ofthe airbag module may be hot forseveral minutes. For location of theairbags, seeWhere Are theAirbags?075.
The parts of the airbag that comeinto contact with you may be warm,but not too hot to touch. There maybe some smoke and dust comingfrom the vents in the deflatedairbags. Airbag inflation does notprevent the driver from seeing out ofthe windshield or being able to steerthe vehicle, nor does it preventpeople from leaving the vehicle.
{Warning
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.

it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that mayautomatically unlock the doors, turnon the interior lamps and hazardwarning flashers, and shut off thefuel system after the airbags inflate.The feature may also activate,without airbag inflation, after anevent that exceeds a predeterminedthreshold. You can lock the doors,and turn off the interior lamps, andturn off the hazard warning flashersby using the controls for thosefeatures.

the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough toinflate the airbag, windshields arebroken by vehicle deformation.Additional windshield breakage mayalso occur from the front outboardpassenger airbag.
.Airbags are designed to inflateonly once. After an airbaginflates, you will need some newparts for the airbag system.If you do not get them, the
airbag system will not be thereto help protect you in anothercrash. A new system will includeairbag modules and possiblyother parts. The service manualfor the vehicle covers the needto replace other parts.
.The vehicle has a crash sensingand diagnostic module whichrecords information after acrash. SeeVehicle DataRecording and Privacy0484andEvent DataRecorders0484.
.Let only qualified technicianswork on the airbag systems.Improper service can mean thatan airbag system will not workproperly. See your dealer forservice.
Airbag On-Off Switch
If the passenger side instrumentpanel endcap has the switchpictured in the following illustration,the vehicle has an airbag on-offswitch that you can use to manually
turn on or off the front outboardpassenger frontal airbag. SeeInstrument Panel06.
If the vehicle does not have anairbag on-off switch, it may have apassenger sensing system. SeePassenger Sensing System082.
This switch should only be turned tothe off position if the person in thefront outboard passenger position isamemberofapassengerriskgroupidentified by the nationalgovernment as follows:

132 Instruments and Controls
When the ignition is on, the fuelgauge indicates about how muchfuel is left in the tank.
There is an arrow near the fuelgauge pointing to the side of thevehicle the fuel door is on.
When the indicator nears empty, thelow fuel light comes on. There still isalittlefuelleft,butthevehicleshould be refueled soon.
Here are four things that someowners ask about. None of theseshow a problem with the fuel gauge:
.At the service station, the fuelpump shuts off before the gaugereads full.
.It takes a little more or less fuelto fill up than the gaugeindicated. For example, thegauge may have indicated thetank was half full, but it actuallytook a little more or less thanhalf the tank's capacity to fillthe tank.
.The gauge moves a little whileturning a corner or speeding up.
.The gauge takes a few secondsto stabilize after the ignition isturned on, and goes back toempty when the ignition isturned off.

Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
costly repairs not covered by the
vehicle warranty. This could also
affect the vehicle’sabilitytopass

If the light is flashing :Amalfunction has been detected thatcould damage the emission controlsystem and increase vehicleemissions. Diagnosis and servicemay be required.
To h e l p p r e v e n t d a m a g e , r e d u c evehicle speed and avoid hardaccelerations and uphill grades.
If towing a trailer, reduce theamount of cargo being hauled assoon as possible.
If the light continues to flash, find asafe place to park. Turn the vehicleoff and wait at least 10 secondsbefore restarting the engine. If thelight is still flashing, follow theprevious guidelines and see yourdealer for service as soon aspossible.
If the light is on steady :Amalfunction has been detected.Diagnosis and service may berequired.
Check the following:
.If fuel has been added to thevehicle using the capless funneladapter, make sure that it hasbeen removed. See“Filling theTa n k w i t h a P o r t a b l e G a s C a n”underFilling the Tank0313.The diagnostic system candetect if the adapter has beenleft installed in the vehicle,allowing fuel to evaporate intothe atmosphere. A few drivingtrips with the adapter removedmay turn off the light.
.Poor fuel quality can causeinefficient engine operation andpoor driveability, which may goaway once the engine is warmedup. If this occurs, change thefuel brand. It may require atleast one full tank of the properfuel to turn the light off. SeeFuel0311.
If the light remains on, see yourdealer.

Trailering is different than justdriving the vehicle by itself.Trailering means changes inhandling, acceleration, braking,durability, and fuel economy.Successful, safe trailering takescorrect equipment, and it has to beused properly.
The following information has manytime-tested, important trailering tipsand safety rules. Many of these are
important for your safety and that ofyour passengers. Read this sectioncarefully before pulling a trailer.
Weight of the Trailer
Safe trailering requires monitoringthe weight, speed, altitude, roadgrades, outside temperature, andhow frequently the vehicle is used topull a trailer. Take into considerationany special equipment on thevehicle, and the amount of tongueweight the vehicle can carry. See“Weight of the Trailer Tongue”laterin this section for more information.
Trailer weight rating (TWR) forpickup models is calculatedassuming the tow vehicle has thedriver, a front seat passenger, andall required trailering equipment.Weight of additional optionalequipment, passengers, and cargoin the tow vehicle must besubtracted from the trailer weightrating.
Ask your dealer for traileringinformation or advice.
For kingpin weight and trailertongue weight information, see“Weight of the Trailer Tongue”laterin this section.
Use the following chart to determinehow much the vehicle can weigh,based upon the vehicle model andoptions.
