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 the vehicle's speed as it goes down steep mountain roads, but then you would also want to use the brakes off and on. Notice: Driving in SECOND (2) for more than 25 miles (40 km) or at speeds over 55 mph (90 km/h), can cause damage to your engine and/or transmission. Also, shifting into SECOND (2) at speeds above 65 mph (105 km/h) can cause damage. Drive in DRIVE (D) instead of SECOND (2). FIRST (1): This position reduces vehicle speed even more than SECOND (2) without using your brakes. It can be used on very steep hills, or in deep snow or mud. If the shift lever is moved to FIRST (1), 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 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. Performance Shifting with TAP-Shift® If the vehicle is equipped with a 5.3L V8 engine, it may have this feature. It allows you to change gears similar to a manual transmission. To fully use this feature, do the following: 1. The MANUAL (M) position can be selected while the vehicle is moving. The current transmission position will continue to be displayed on the Driver Information Center (DIC) and Head-Up Display (HUD), if equipped. 2. Move the shift lever to the MANUAL (M). 2-31
