436 STARTING AND OPERATING WARNING! Do not coast in NEUTRAL and never turn off the ignition to coast down a hill. These are unsafe practices that limit your response to changing traffic or road conditions. You might lose control of the vehicle and have a collision. DRIVE This range should be used for most city and highway driving. It provides the smoothest upshifts and downshifts, and the best fuel economy. The transmission automatically upshifts through underdrive first and second gears, direct third gear and overdrive fourth and fifth gears. The DRIVE position provides optimum driving characteristics under all normal operating conditions. To access all six available gears, you must use the Electronic Range Select (ERS) feature (refer to "Electronic Range Select (ERS)" in this section). When frequent transmission shifting occurs (such as when operating the vehicle under heavy loading conditions, in hilly terrain, traveling into strong head winds, or while towing heavy trailers), use the Electronic Range Select (ERS) feature (refer to "Electronic Range Select (ERS)" in this section) to select a lower gear range. Under CAUTION! Towing the vehicle, coasting, or driving for any other reason with the transmission in NEUTRAL can result in severe transmission damage. Refer to "Recreational Towing" in "Starting And Operating" and "Towing A Disabled Vehicle" in "What To Do In Emergencies" for further information.
