Features & Controls Forward Gears(CONT.) 1 (First Gear): This position gives you even more power (but lower fuel economy) than 2. You can use it on very steep hills, or in deep snow or mud. If the selector lever is put in 1, the transaxle won't shift into first gear until the vehicle is going slowly enough. If your front wheels can't rotate, don't try to drive. This might happen if you were stuck in very deep sand or mud 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 only the accelerator pedal. This could overheat and damage the transaxle. Use your brakes or shift into P (Park) to hold your vehicle in position on a hill. Performance Shifting(opTIoN) Press PERFORM SHIFT to allow the transaxle to shift at higher engine speeds, increasing acceleration performance. An indicator light on the switch will glow when performance shifting is in operation. Downshifts will occur at a lower percentage of accelerator application while you're in thePERFORM SHIFT mode. Press NORMAL SHIFT to have the transaxle shift at lower engine speeds, increasing fueleconomy. An indicator light on the switch will glow when normal shifting is in operation. 66
