Tire Pressure Monitor
This vehicle may have a TirePressure Monitor System (TPMS).
The low tire pressure warning lightalerts to a significant loss inpressure of one of the vehicle'stires. If the warning light comes on,stop as soon as possible and inflatethe tires to the recommendedpressure shown on the Tire and
Loading Information label. SeeVehicle Load Limits0226.Thewarning light will remain on until thetire pressure is corrected.
The low tire pressure warning lightmay come on in cool weather whenthe vehicle is first started, and thenturn off as the vehicle is driven. Thismay be an early indicator that thetire pressures are getting low andthe tires need to be inflated to theproper pressure.
The TPMS does not replace normalmonthly tire maintenance. Maintainthe correct tire pressures.
SeeTire Pressure MonitorSystem0325.
Fuel (Gasoline)
Regular Fuel
Use only unleaded gasoline rated87 octane or higher in your vehicle.Do not use gasoline with an octanerating lower as it may result invehicle damage and lower fueleconomy. SeeFuel0266.
Fuel (Diesel)
For diesel vehicles, do not usegasoline. See“Fuel for DieselEngines”in the Duramax dieselsupplement.
E85 or FlexFuel
No E85 or FlexFuel
Gasoline-ethanol fuel blends greaterthan E15 (15% ethanol by volume),such as E85, cannot be used in thisvehicle.

266 Driving and Operating
LDW alerts may occur due to tarmarks, shadows, cracks in the road,temporary or construction lanemarkings, or other roadimperfections. This is normal systemoperation; the vehicle does not needservice. Turn LDW off if theseconditions continue.
Fuel
For diesel engine vehicles, see“Fuel for Diesel Engines”in theDuramax diesel supplement.
GM recommends the use of TOPTIER®detergent gasoline to keepthe engine cleaner and reduceengine deposits. Seewww.toptiergas.com for a list of TOPTIER detergent gasoline marketersand applicable countries.
Do not use any fuel labeled E85 orFlexFuel. Do not use gasoline withethanol levels greater than 15% byvolume.
Use regular unleaded gasolinemeeting ASTM specification D4814with a posted octane rating of 87 orhigher. Do not use gasoline with aposted octane rating of less than 87,as this may cause engine knock andwill lower fuel economy.
Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so
may damage the vehicle and void
its warranty:
.For vehicles which are notFlexFuel, fuel labeledgreater than 15% ethanol byvolume, such as mid-levelethanol blends (16–50%ethanol), E85, or FlexFuel.
.Fuel with any amount ofmethanol, methylal, andaniline. These fuels cancorrode metal fuel systemparts or damage plastic andrubber parts.

Caution (Continued)
.Fuel containing metals suchas methylcyclopentadienylmanganese tricarbonyl(MMT), which can damagethe emissions controlsystem and spark plugs.
.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 emission
control 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)011 8.Ifthisoccurs, 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”inFuel0266.
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. SeeFuel0266.
If TOP TIER detergent gasoline isnot available, one bottle of GM FuelSystem Treatment Cleaner added tothe fuel tank at every engine oil
