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.

Driving and Operating 255
Traction is reduced on hard packedsnow and ice and it is easy to losecontrol. Reduce vehicle speed whendriving on hard packed snowand ice.
{Warning
Driving on frozen lakes, ponds,
or rivers can be dangerous. Ice
conditions vary greatly and the
vehicle could fall through the ice;
you and your passengers could
drown. Drive your vehicle on safe
surfaces only.
Driving in Water
{Warning
Driving through rushing water can
be dangerous. Deep water can
sweep your vehicle downstream
and you and your passengers
could drown. If it is only shallow
water, it can still wash away the
ground from under your tires.
(Continued)
Warning (Continued)
Traction could be lost, and the
vehicle could roll over. Do not
drive through rushing water.
Caution
Do not drive through standing
water if it is deep enough to cover
the wheel hubs, axles, or exhaust
pipe. Deep water can damage the
axle and other vehicle parts.
If the standing water is not too deep,drive slowly through it. At fasterspeeds, water splashes and thevehicle can stall. When goingthrough water, the brakes get wetand it may take longer to stop. See“Driving on Wet Roads”later in thissection.
After Off-Road Driving
Remove any brush or debris thathas collected on the underbody orchassis, or under the hood. Theseaccumulations can be a fire hazard.
After operation in mud or sand,have the brake linings cleaned andchecked. These substances cancause glazing and uneven braking.Check the body structure, steering,suspension, wheels, tires, andexhaust system for damage andcheck the fuel lines and coolingsystem for any leakage.
More frequent maintenance serviceis required. See theMaintenanceSchedule0452.
Driving on Wet Roads
Rain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep-standing or flowing water.

.Fuel with a posted octanerating of less than therecommended fuel. Usingthis fuel will lower fueleconomy and performance,and may decrease the life ofthe emissions catalyst.
California Fuel
Requirements
If the vehicle is certified to meetCalifornia Emissions Standards, it isdesigned to operate on fuels thatmeet California specifications. Seethe underhood emission controllabel. If this fuel is not available instates adopting California EmissionsStandards, the vehicle will operatesatisfactorily on fuels meetingfederal specifications, but emissioncontrol system performance may beaffected. The malfunction indicatorlamp could turn on and the vehiclemay not pass a smog-check test.SeeMalfunction Indicator Lamp(Check Engine Light)0138.Ifthis
occurs, return to your authorizeddealer for diagnosis. If it isdetermined that the condition iscaused by the type of fuel used,repairs may not be covered by thevehicle warranty.
Fuels in Foreign
Countries
The U.S., Canada, and Mexico postfuel octane ratings in anti-knockindex (AKI). For fuel not to use in aforeign country, see“ProhibitedFuels”inFuel0311.
Fuel Additives
To k e e p f u e l s y s t e m s c l e a n , T O PTIER Detergent Gasoline isrecommended. SeeFuel0311.
If TOP TIER Detergent Gasoline isnot available, one bottle of GM FuelSystem Treatment Cleaner added tothe fuel tank at every engine oilchange, can help. GM Fuel SystemTreatment Cleaner is the onlygasoline additive recommended byGeneral Motors. It is available atyour dealer.
If your vehicle is able to use E85 orFlexFuel, GM Fuel SystemTreatment Cleaner - FlexFuel is theonly recommended additive for use.Do not use any other additives withan E85 or FlexFuel vehicle. SeeE85 or FlexFuel0312.
E85 or FlexFuel
Vehicles with a yellow sticker on thefuel door can use either unleadedgasoline or fuel containing up to85% ethanol (E85). All othervehicles should use only theunleaded gasoline as described inFuel0311.
The use of E85 or FlexFuel isencouraged when the vehicle isdesigned to use it. E85 or FlexFuelis made from renewable sources.
To h e l p l o c a t e f u e l s t a t i o n s t h a tcarry E85 or FlexFuel, the U.S.Department of Energy has analternative fuels website. Seewww.afdc.energy.gov/afdc/locator/stations.

selection of Tow/Haul when thevehicle is unloaded. Such aselection when unloaded may resultin unpleasant engine andtransmission driving characteristicsand reduced fuel economy. Tow/Haul is recommended only whenpulling a heavy trailer or a large orheavy load.
Integrated Trailer Brake
Control System
The vehicle may have an IntegratedTrailer Brake Control (ITBC) systemfor use with electric trailer brakes ormost electric over hydraulic trailerbrakes.
This symbol is on the Trailer BrakeControl Panel on vehicles with anITBC system. The power output tothe trailer brakes is based on theamount of brake pressure beingapplied by the vehicle’sbrake
system, and on the type of trailerbrakes detected. This availablepower output to the trailer brakescan be adjusted to a wide range oftrailering situations.
The ITBC system is integrated withthe vehicle’sbrake,antilockbrake,and StabiliTrak systems. In traileringconditions that cause the vehicle’santilock brake or StabiliTraksystems to activate, power sent tothe trailer's brakes will beautomatically adjusted to minimizetrailer wheel lock-up. This does notimply that the trailer has StabiliTrak.
If the vehicle’sbrake,antilockbrake,or StabiliTrak systems are notfunctioning properly, the ITBCsystem may not be fully functionalor may not function at all. Make sureall of these systems are fullyoperational to ensure fullfunctionality of the ITBC system.
The ITBC system is poweredthrough the vehicle's electricalsystem. Turning the ignition off willalso turn off the ITBC system. TheITBC system is fully functional onlywhen the ignition is in ON/RUN.
{Warning
Connecting a trailer that has an
air brake system may result in
reduced or complete loss of trailer
braking. There may be an
increase in stopping distance or
trailer instability which could
result in personal injury or
damage to the vehicle, trailer,
or other property. Use the ITBC
system only with electric or
electric over hydraulic trailer
brakes.

406 Vehicle Care
Caution
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:
.Tire overloading and
overheating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can
result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.
The Tire and Loading
Information label on the vehicle
indicates the original equipment
tires and the correct cold tire
inflation pressures. The
recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity.
For additional information
regarding how much weight the
vehicle can carry, and an
example of the Tire and Loading
Information label, seeVehicle
Load Limits0259.Howthe
vehicle is loaded affects vehicle
handling and ride comfort. Never
load the vehicle with more
weight than it was designed to
carry.
When to Check
Check the tires once a month
or more.
Do not forget the spare tire,
if the vehicle has one. See
Full-Size Spare Tire0431for
additional information.
How to Check
Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven
for at least three hours or no
more than 1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
