THIRD ( ) This position is also used for normal 3: driving, however, it offers more power and lower fuel economy than AUTOMATICOVERDRIVE (D). Here are some times you might choose THIRD (3) instead of AUTOMATIC OVERDRIVE (D): 0 When driving on hilly, winding roads. When going down a steep hill. 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 th'eselector lever is put in FIRST (1)'the transaxle won't shift into firstgear until the vehicle is going slowly enough. 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. NOTICE: If your front wheels can'trotate, don't try to drive. This might happen if you were stuck in very deepsand ormud or were up against a solid object. You could damage your transaxle. Also, if you stop when going uphill, don't hold your vehicle there with onlythe accelerator pedal. This could overheat and damage the transaxle. Use your brakes or shift into PARK (P) to hold your vehicle in position on hill. a NOTICE: Don't drive in SECOND (2) for more than 25 miles (41 km), or at speeds over55 mph (88 k d ) , or you can damage your transaxle. Use AUTOMATIC OVERDRIVE or (D) THIRD (3) as much as possible. Don't shift into SECOND (2) unless you are going slowerthan 65 mph (105 km/h), or you candamage your engine. 2-23
