Automatic Transmission Drive (D3) - This position is similar to D4, except only the first three gears are selected. Use D3 to provide engine braking when going down a steep hill. D3 can also keep the transmission from cycling between third and fourth gears in stop-and-go driving. For faster acceleration when in D3 or D4, you can get the transmission to automatically downshift by pushing the accelerator pedal to the floor. The transmission will shift down one or two gears, depending on your speed. Second (2) - To shift to Second, press the release button on the side of the shift lever. This position locks the transmission in second gear. It does not downshift to first gear when you come to a stop. Second gives you more power when climbing, and increased engine braking when going down steep hills. Use second gear when starting out on a slippery surface or in deep snow. It will help reduce wheel spin. Whenever you move the shift lever to a lower gear, the transmission downshifts only if the engine's redline will not be exceeded in the lower gear. First (1) - To shift from Second to First, press the release button on the side of the shift lever. With the lever in this position, the transmission locks in First gear. By upshifting and downshifting through 1, 2, D3, and D4, you can operate this transmission much like a manual transmission without .a clutch pedal. Driving
