2-22 Features and Controls 1 (First): This position reduces vehicle speed even more than 2 (Second) without using the brakes. You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in 1 (First) while the vehicle is moving forward, the transmission will not shift into first gear 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 transmission. The repair will not be covered by the vehicle warranty. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place. Manual Transmission Operation shift into 1 (First), put the shift lever in Neutral and let up on the clutch. Then press the clutch pedal back down and shift into 1 (First). 2 (Second): Press the clutch pedal as you let up on the accelerator pedal and shift into 2 (Second). Then, slowly let up on the clutch pedal as you press the accelerator pedal. 3 (Third), 4 (Fourth) and 5 (Fifth): Shift into 3 (Third), 4 (Fourth) and 5 (Fifth) the same way you do for 2 (Second). Slowly let up on the clutch pedal as you press the accelerator pedal. To stop, let up on the accelerator pedal and press the brake pedal. Just before the vehicle stops, press the clutch pedal and the brake pedal, and shift to Neutral. Neutral: Use this position when you start or idle the engine. This is the shift pattern. Vehicles with a manual transmission operate as described below: 1 (First): Press the clutch pedal and shift into 1 (First). Then slowly let up on the clutch pedal as you slowly press down on the accelerator pedal. You can shift into 1 (First) when you are going less than 20 mph (30 km/h). If you have come to a complete stop and it is hard to Hill Start Assist H3 and H3T vehicles have a Hill Start Assist feature, which may be useful when stopped on a grade.
