How to Reset the Tire Pressure Indicator on a 2007 Chevy Impala

    Resetting the Tire Pressure Light

    • 1). Allow the vehicle to cool down for three hours, if recently driven, so the tires may cool.

    • 2). Unscrew the caps from the end of all four valve stems -- the rubber valve protruding from each rim. Set these caps in a secure area so that you do not lose them.

    • 3). Press the end of a tire pressure gauge firmly onto the end of the valve stem -- the brass part -- and read the pressure measurement on the gauge. Compare this reading to the correct tire pressure for the 2007 Impala, which is 30 psi on the front and rear. Any tire lower than the recommended pressure by more than 2 psi requires adjustment.

    • 4). Pull the Impala next to an air hose connected to a compressed air source with a tire inflation chuck attached to it. If you need to drive to a compressed air source, try to find an area no more than a mile away, as anything more than a mile can warm up your tires and increase the tire pressure.

    • 5). Press the tire inflation chuck onto the end of the valve stem firmly to start the flow of air into the tire. In order to estimate how long to add air to the tire, it is safe to assume that the tire pressure increases 1 psi per each 3 to 5 seconds you add air.

    • 6). Pull the tire inflation chuck from the valve stem once the estimated amount of inflation time has elapsed. Recheck and adjust the tire pressure by following Steps 2 and 4.

    • 7). Repeat Steps 3, 5 and 6 on the remaining tires that require air.

    • 8). Tighten the valve stem caps onto the valve stems.

    • 9). Drive the Impala and observe as the TPMS telltale light on the dashboard extinguishes nearly immediately.

    Matching Tire Positions

    • 1). Park the Impala near a compressed air source with an air hose and tire inflation chuck. Remove the valve stem caps off all four tires.

    • 2). Engage the parking brake and turn the Impala’s ignition to the “Run” position. Do not start the vehicle.

    • 3). Press and release the “Info” button on the driver’s information center until “Learn Tire Positions” appears on the DIC display. Press and release the “Set/Reset” button on the DIC and listen for the horn to beep twice, indicating the system is in lean mode -- “Tire Learning Active” displays on the DIC, as well.

    • 4). Press the metal button inside the top of the valve stem, on the left-front tire, with a small flat-head screwdriver to decrease tire pressure until you hear the horn chirp -- about 5 to 30 seconds. The chirp indicates the Impala has learned that tire’s position.

    • 5). Repeat Step 4 on the remaining three tires in the following order: right-front, right-rear and left-rear.

    • 6). Turn the ignition to the “Off” position and set the tire pressure on all four tires to 30 psi following Steps 3, 5 and 6 in the section titled “Resetting the Tire Pressure Light” on each tire.
