STARTING AND OPERATING 257 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. On vehicles equipped with 4.7L or 5.7L engines, use of ERS (or Tow/Haul mode) also enables a additional underdrive gear which is not normally used during through-gear accelerations. This additional grade improves vehicle performance and cooling capability when towing a trailer on certain grades. In ERS mode (on all transmissions), 1st through 3rd gear are underdrive gears and 4th gear is direct drive. ERS 5th gear (Overdrive) is the same as the normal 4th gear. WARNING! Do not downshift for additional engine braking on a slippery surface. The drive wheels could lose their grip and the vehicle could skid.

NOTE: To select the proper gear position for maximum deceleration (engine braking), move the shift lever to the left "D(-)" and hold it there. The transmission will shift to the range from which the vehicle can best be slowed down.
