THIRD (3): This position is also used for normal driving, however, it offers more power and lower fuel economy than AUTOMATIC OVERDRIVE Here are some times you might choose THIRD (3) instead of AUTOMATIC OVERDRIVE (@ ): (a). 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 lever is put in FIRST (I), the transaxle won't shift into FIRST (1) until the vehicle is going slowly enough. Notice: If your front wheels won't turn, don't try to drive. This might happen if you were stuck in very deep sand or mud orwere up against a solid object. You could damage your transaxle. Also, if you stop when going uphill, don't hold your vehicle there with only the acceleratorpedal. This could overheat and damage the transaxle. Use your brakes to hold your vehiclein position on a hill. When driving on hilly, winding roads, when towing a trailer, so there is less shifting between gears, or when going down a steep hill. SECOND (2): This position gives you more power but lower fuel economy than AUTOMATIC OVERDRIVE or THIRD (3). 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. (0 2-28
