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 andLoading Information label. SeeVehicle Load Limits0178.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 MonitorSystem0257.
Fuel
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. SeeFuel0207.

Warning (Continued)
departing the lane on the side
where it has detected a lane
marking. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LDW in
bad weather conditions.
How the System Works
The LDW camera sensor is on thewindshield ahead of the rearviewmirror.
To t u r n L D W o n a n d o f f , p r e s s@on
the center console. The controlindicator will light when LDW is on.
When LDW is on,@is green if
LDW is available to warn of a lanedeparture. If the vehicle crosses adetected lane marking without using
the turn signal in that direction,@
changes to amber and flashes.Additionally, there will be threebeeps on the right or left, dependingon the lane departure direction.
When the System Does Not
Seem To Work Properly
The system may not detect lanes aswell when there are:
.Close vehicles ahead.
.Sudden lighting changes, suchas when driving through tunnels.
.Banked roads.
If the LDW system is not functioningproperly when lane markings areclearly visible, cleaning thewindshield may help.
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
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 a

posted 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.
.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 emissioncontrol system performance may beaffected. The malfunction indicatorlamp could turn on and the vehicle
may not pass a smog-check test.SeeMalfunction Indicator Lamp(Check Engine Light)011 2.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”inFuel0207.
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. SeeFuel0207.
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 only
