2008 Jeep Grand Cherokee Owner's Manual - Page 287

STARTING AND OPERATING 287 R (Reverse) Use this range only after the vehicle has come to a complete stop. N (Neutral) Shift into N (Neutral) when the vehicle is standing for prolonged periods with the engine running. The engine may be started in this range. Set the parking brake if you must leave the vehicle. NOTE: Towing the vehicle, coasting, or driving for any other reason with selector lever in N (Neutral) can result in severe transmission damage. Refer to "Recreational Towing" in Section 5 and "Towing a Disabled Vehicle" in Section 6 of this manual. D (Drive) Shift into D (Drive) only when the vehicle is at a complete stop and the brakes are firmly applied. The transmission automatically upshifts through fifth gear. The D (Drive) position provides optimum driving characteristics under all normal operating conditions. Electronic Range Select (ERS)Operation The Electronic Range Select (ERS) shift control allows you to move the shifter left (-) or right (+) when the shifter is in the D (Drive) position, allowing the selection of the desired top gear. For example, if the driver shifts the transmission into 3 (third gear), the transmission will never shift above third gear, but can shift down to 2 (second) or 1 (first), when needed. When in the D (Drive) position, the first tap to the left (-), will show the current gear. For example, if you are in D (Drive) and are in 3rd gear, when you tap the gear shift one time to the left (-), the display will show 3. Another tap to the left (-) will shift the transmission into 2nd gear. 5
