Driving N (Neutral) With the gearshift lever in the N (Neutral) position, the vehicle can be started and is free to roll. Hold the brake pedal down while in this position. P R N D D 1 (Overdrive) The (Overdrive) position is the P R N D D 1 normal driving position for an automatic overdrive transaxle. When in the (Overdrive) position, the transaxle works the same way as when in D (Drive). However, when your vehicle cruises at a constant speed for any length of time, the transaxle shifts into a fourth gear (Overdrive) and allows the torque converter to lock-up. Overdrive will increase your fuel economy when you travel at cruising speeds. Overdrive may not be appropriate for certain terrains. If the transaxle shifts back and forth between third and fourth gears while you are driving on hilly roads, or if your vehicle requires additional power for climbing hills, shift into D (Drive). 126
