FIRST (1): This position reduces vehicle speed even more than SECOND (2) without using your brakes. You can use it on very steep hills, or in deep snow or mud. If the shift lever is put in FIRST (1) while the vehicle is moving forward, 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. Parking Brake The parking brake pedal is located to the left of the regular brake pedal, near the driver's door. Performance Shifting If your vehicle has this feature, it can detect a change in driving patterns. If you make an aggressive driving maneuver, the vehicle's transaxle automatically shifts to the lowest possible gear to maximize vehicle performance. The vehicle will automatically return to normal operation when you return to normal driving patterns. To set the parking brake, hold the regular brake pedal down with your right foot and push the parking brake pedal down with your left foot. 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 your vehicle serviced. 121
