Engine Oil Life System
The engine oil life system calculatesengine oil life based on vehicle useand, on most vehicles, displays aDriver Information Center (DIC)message when it is necessary tochange the engine oil and filter. Theoil life system should be reset to100% only following an oil change.
Resetting the Oil Life System
To r e s e t t h e e n g i n e o i l l i f e s y s t e m :
1. Display OIL LIFE REMAININGon the DIC. SeeDriverInformation Center (DIC) (BaseLevel)0126orDriverInformation Center (DIC)(Uplevel)0129.Ifthevehicledoes not have DIC buttons, thevehicle must be in P (Park) toaccess this display.
2. Press and holdVon the DIC,
or SET/CLR on the turn signallever if the vehicle does nothave DIC buttons, for severalseconds. The oil life willchange to 100%.
The oil life system can also be resetas follows:
1. Display OIL LIFE REMAININGon the DIC. SeeDriverInformation Center (DIC) (BaseLevel)0126orDriverInformation Center (DIC)(Uplevel)0129.
2. Fully press the acceleratorpedal slowly three times withinfive seconds. If the displayshows 100%, the system isreset.

Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation0326.
Check that all wheel nuts are
properly tightened. See“Wheel
Nut Torque”underCapacities
and Specifications0380.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
ascraperorwirebrushlaterto
remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
When It Is Time for New
Tires
Factors, such as maintenance,temperatures, driving speeds,vehicle loading, and road conditionsaffect the wear rate of the tires.
Treadwear indicators are one way totell when it is time for new tires.Treadwear indicators appear whenthe tires have only 1.6 mm (1/16 in)or less of tread remaining. Some
commercial truck tires may not havetreadwear indicators. SeeTireInspection0329andTire Rotation0329for additional information.
The rubber in tires ages over time.This also applies to the spare tire,if the vehicle has one, even if it isnever used. Multiple factorsincluding temperatures, loadingconditions, and inflation pressuremaintenance affect how fast agingtakes place. GM recommends thattires, including the spare ifequipped, be replaced after sixyears, regardless of tread wear. Thetire manufacture date is the last fourdigits of the DOT Tire IdentificationNumber (TIN) which is molded intoone side of the tire sidewall. Thefirst two digits represent the week(01-52) and the last two digits, theyear. For example, the third week ofthe year 2010 would have afour-digit DOT date of 0310.

Passenger Compartment Air
Filter
The passenger compartment airfilter removes dust, pollen, andother airborne irritants from outsideair that is pulled into the vehicle.The filter should be replaced as partof routine scheduled maintenance.Inspect the passenger compartmentair filter every 36 000 km(22,500 mi) or two years, whichevercomes first. Replace if necessary.More frequent replacement may beneeded if the vehicle is driven inareas with heavy traffic, areas withpoor air quality, or areas with highdust levels. Replacement may alsobe needed if there is a reduction inair flow, excessive window fogging,or odors.
