TAP Shift Operation
WARNING: This page is about a different car, the 2005 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
The TAP Shift system allows the driver to manually shift gears by using the TAP Shift switches located on the shift lever. Pushing either TAP Shift switch will command an upshift and pulling either switch will command a downshift. The TAP Shift system is activated when the gear selector is placed in the manual (L) position and is deactivated in all other positions.
