SECOND (2): This position gives you more power but lower fuel economy. You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads, but then you would also want to use your brakes off and on. If you manually select SECOND (2), the transmission will drive in second gear. You may use this feature for reducing torque to the rear wheels when you are trying to start your vehicle from a stop on slippery road surfaces. FIRST (1): This position gives you even more power (but lower fuel economy) than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the shift selector lever is put in FIRST (1), the transmission will not shift into first gear until the vehicle is going slow enough. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place. Tow/Haul Mode Your vehicle is equipped with a tow/haul button. The button is located on the end of the column shift lever. You can use this feature to assist when towing or hauling a heavy load. To select the tow/haul mode, press in the button. The TOW/HAUL light on the instrument panel cluster will come on. To go back to normal operation, press the button again. The indicator light on the instrument panel cluster will go out. See Tow/Haul Mode Light on page 3-37 for more information. 2-22
