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 totar marks, shadows, cracks inthe road, temporary or constructionlane markings, or other roadimperfections. This is normal systemoperation; the vehicle does not needservice. Turn LDW off if theseconditions continue.

GM recommends the use of TOPTIER®detergent gasoline tokeep the engine cleaner andreduce engine deposits. Seewww.toptiergas.com for a list ofTOP TIER detergent gasolinemarketers and applicable countries.
Do not use any fuel labeled E85 orFlexFuel. Do not use gasoline withethanol levels greater than 15% byvolume.
Premium unleaded gasolinemeeting ASTM specification D4814with a posted octane rating of 93 ishighly recommended for best

performance and fuel economy.Unleaded gasoline with an octanerated as low as 87 can be used.Using unleaded gasoline ratedbelow 93 octane, however, will leadto reduced acceleration and fueleconomy. If knocking occurs, use agasoline rated at 93 octane as soonas possible, otherwise, the enginecould be damaged. If heavyknocking is heard when usinggasoline with a 93 octane rating, theengine needs service.
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.

Caution (Continued)
.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.
