2010 Jeep Grand Cherokee Owner Manual SRT8 - Page 247

246 STARTING AND OPERATING Operation By placing the shift lever in the DRIVE position, the shift lever can be moved from side to side. This allows the driver to engage the AutoStick௡ mode. Moving the shift lever to the right (+) or the left (-) will engage the AutoStick௡ mode. In normal driving mode (Boxed "D" displayed in the PRNDL), moving the shift lever to the right (+) will engage the AutoStick௡ mode putting the transmission in the currently engaged gear. Moving the shift lever to the Left (-) will engage the AutoStick௡ mode and downshift the transmission one gear. For example, if the transmission is in Drive mode (a boxed ЉDЉ is displayed in the cluster) and is operating in third gear, tapping the shift lever to the right (+) will engage AutoStick௡ mode (while remaining in third gear) and a boxed Љ3Љ will be displayed in the cluster. Tapping the shift lever to the left (-) would also engage AutoStick௡ mode, but would force a downshift to second gear, and display a boxed Љ2Љ in the cluster.Љ Once AutoStick௡ mode is engaged, a move to the right (+) or left (-) will trigger a upshift (+) or trigger a downshift (-). NOTE: In the AutoStick௡ mode, the transmission will shift up and down when left or right (D-/D+) is manually selected by the driver. The transmission will not allow a downshift if the downshift would result in an engine overspeed condition. The transmission will always allow a upshift from first to second gear, however 2nd - 3rd, 3rd - 4th, and 4th - 5th upshifts will not be allowed if the vehicle speed is too low to maintain operation in the selected gear. The transmission will automatically downshift as the vehicle slows to a stop (to prevent engine lugging) and will display the current gear. After a stop, the driver should manually upshift (D+) the transmission as the vehicle is accelerated.
