2 (Second): This position reduces vehicle speed even more than 3 (Third) without using the brakes. You can use 2 (Second) on hills. It can help control vehicle speed as you go down steep mountain roads, but then you would also want to use the brakes off and on. Notice: Driving in 2 (Second) for more than 25 miles (40 km) or at speeds over 55 mph (90 km/h) may damage the transmission. Also, shifting into 2 (Second) at speeds above 65 mph (105 km/h) can cause damage. Drive in 3 (Third) or D (Drive) instead of 2 (Second). 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 going 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. Parking Brake The parking brake pedal is located to the left of the regular brake pedal, near the driver door. To set the parking brake, hold the regular brake pedal down, then push the parking brake pedal down. If the ignition is on, the brake system warning light on the instrument panel cluster should come on. If it does not, you need to have the vehicle serviced. A warning chime will sound if the parking brake is set, the ignition is on, and the vehicle speed is greater than 5 mph (8 km/h). The brake light will come on and stay on until the parking brake is released. See Brake System Warning Light on page 4 ‑ 32 for more information. 3-26
