THIRD (3): This position is also used for normal driving, but it offers more power and lower fuel economy than AUTOMATIC OVERDRIVE (D). Here are some times you might choose THIRD (3) instead of AUTOMATIC OVERDRIVE (D): SECOND (2): This position gives the vehicle more power but lower fuel economy than THIRD (3). You can use SECOND (2) on hills. It can help control the speed going down steep mountain roads, but then you would also want to use the brakes off and on. FIRST (1): This position gives the vehicle 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 (1), the transaxle will not shift into first gear until the vehicle is going slowly enough. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transaxle. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes, or parking brake to hold the vehicle in place. • When driving on hilly, winding roads. • When towing a trailer, so there is less shifting between gears. • When going down a steep hill. • When driving in no-highway scenarios such as city streets. Notice: Driving in SECOND (2) for more than 25 miles (40 km) or at speeds over 55 mph (90 km/h) may damage the transaxle. Also, shifting into SECOND (2) at speeds above 65 mph (105 km/h) can cause damage. Drive in THIRD (3) or AUTOMATIC OVERDRIVE (D) instead of SECOND (2). 2-29
