SECOND (2): This position gives the vehicle more power but lower fuel economy than THIRD (3). SECOND (2) can be used 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 transaxle. Also, shifting into SECOND (2) at speeds above 65 mph (105 km/h) can cause damage. Drive in AUTOMATIC OVERDRIVE (D) instead of SECOND (2). FIRST (1): This position gives the vehicle even more power but lower fuel economy than SECOND (2). It can be used on very steep hills, or in deep snow or mud. If the shift lever is moved to FIRST (1), the transaxle 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 transaxle. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes, or parking brake to hold the vehicle in place. Performance Shifting with TAP-Shift® If the vehicle is equipped with the 3800 V6 Supercharged engine or the 5.3L V8 engine, your vehicle may have this feature. It allows you to change gears similar to a manual transaxle. To fully use this feature, do the following: 1. The MANUAL (M) position can be selected while the vehicle is moving. The current transaxle 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). 2-28
