AUTOMATIC OVERDRIVE (D): This position is for normal driving with the automatic transaxle. If you need more power for passing, and you are: Here are some times you might choose INTERMEDIATE (I) instead of AUTOMATIC OVERDRIVE (D): • Going less than about 35 mph (55 km/h), push your accelerator pedal about halfway down. • Going about 35 mph (55 km/h), push your accelerator all the way down. INTERMEDIATE (I): This position is also used for normal driving. However, it offers braking from the engine for slight downgrades where the vehicle would otherwise accelerate due to steepness of grade. If repetitive shifts occur between third and fourth gears on steep uphills, this position can be used to prevent repetitive shifting. Fuel economy will be lower than AUTOMATIC OVERDRIVE (D). • When driving on hilly, winding roads. • When towing a trailer, so there is less shifting between gears. LOW (L): This position gives you even more power but lower fuel economy than INTERMEDIATE (I). You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in LOW (L), the transaxle will not shift into LOW (L) 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. 2-24
