0 @ (Overdrive) This position is fornormal driving. If you need more power for passing, and you're: - Going less than about 35 mph (56 ludh), push your accelerator pedal about halfway down. Going about 35 mph (56 km/h) or more, push the accelerator pedal all the way down. You'll shift down to the next gear and have more power. - @ should not be used when towing a trailer, carrying a heavy load, or driving on steep hills, Select"D" (Third Gear) when operating the vehicle under any of these conditions. 0 D (Third Gear)- This is like @, but you never go into Overdrive. You should use "D" (Third Gear) when towing a trailer, carrying a heavy load or driving on steep hills. 0 2 (Second Gear) -This position gives you more power but lower fuel economy. You can use "2" (Second Gear) 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 "2" (Second Gear), the transmission will drive in second gear. You may use this feature forreducing torque to the rear wheels when you are trying to start your vehicle from a stop on slippery road surfaces. 0 1 (First Gear)- This position gives you even more power (but lower fuel economy) than "2" (Second Gear). You can use it on very steep hills, or indeep snow or mud. If the selector lever is put in "1" (First Gear), the transmission won't shift into "I" (First Gear) until the vehicle is going slowly enough. NOTICE: If your rearwheels can't rotate, don't to drive. This might try happen if you were stuck invery deep sand or mud or were up against a solid object. You could damage your transmission or transfer case or both. Also, if you stop whengoing uphill, don't hold your vehicle there with only the acceleratorpedal. This could overheat and damage the transmission. Use your brakes or shift into Park to hold "P" your vehicle in position on a hill.
