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. You will shift down to the next gear and have more power. Downshifting the transmission in slippery road conditions could result in skidding, see "Skidding" under Loss of Control on page 298. 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 THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often. THIRD (3): This position is also used for normal driving. It reduces vehicle speed more than DRIVE (D) without using your brakes. You might choose THIRD (3) instead of DRIVE (D) when driving on hilly, winding roads, when towing a trailer, so there is less shifting between gears and when going down a steep hill. To shift to the THIRD (3) position, you must first press the large button on the shift handle. While the button is pressed, move the shifter in the THIRD (3) position. SECOND (2): This position reduces vehicle speed even more than THIRD (3) without using your brakes. 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. 116
