OEM Indicator Schedules or ALLDATA Mileage Schedules

GM Indicator Based Schedules
GM recommends using an "Indicator Based" maintenance schedule for this vehicle.

ALLDATA Mileage Based Schedules
ALLDATA understands that not all customers prefer to follow indicator based maintenance schedules, so we have included mileage based maintenance schedules.

The mileage based schedules supplied in ALLDATA are estimated to resemble the GM indicator based maintenance schedules as closely as possible.

ALLDATA maintenance schedules are for reference only. They are not intended to replace the GM maintenance schedules.
