To rock your vehicle back and forth to get out of snow, ice, or sand without damaging the transmission, see If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 4-39. NEUTRAL (N): In this position, the engine does not connect with the wheels. To restart when you are already moving, use NEUTRAL (N) only. Also, use NEUTRAL (N) when your vehicle is being towed. DRIVE (D): This position is for normal driving. It provides the best fuel economy for your vehicle. If you need more power for passing, and you are: • Going less than about 35 mph (55 km/h), push the accelerator pedal about halfway down. • Going about 35 mph (55 km/h) or more, push the accelerator all the way down. By doing this, the vehicle shifts down to the next gear and has more power. DRIVE (D) can be used when towing a trailer, carrying a heavy load, driving on steep hills, or for off-road driving. You may want to shift the transmission to a lower gear selection if the transmission shifts too often. Downshifting the transmission in slippery road conditions could result in skidding, see Skidding under Loss of Control on page 4-12. MANUAL MODE (M): This position lets drivers select the range of gears appropriate for current driving conditions. If your vehicle has this feature, see Driver Shift Control (DSC) later in this section. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. The repair will not be covered by your warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place. 2-33 {CAUTION: Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal, your vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while your engine is running at high speed. Notice: Shifting out of PARK (P) or NEUTRAL (N) with the engine running at high speed may damage the transmission. The repairs would not be covered by your warranty. Be sure the engine is not running at high speed when shifting your vehicle.
