SECOND (2): This position gives you more power but lower fuel economy than THIRD (3). You can use SECOND (2) on hills. It can help control your speed as you go down steep mountain roads. You would also then want to use your 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) may damage the transaxle. Also, shifting into SECOND (2) at speeds above 65 mph (105 km/h) can cause damage. Drive in THIRD (3) or AUTOMATIC OVERDRIVE (D) instead of SECOND (2). FIRST (1): This position gives you even more power, but lower fuel economy than SECOND (2). You can use it on very steep hills, or in deep snow or mud. If the shift lever is in 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. Parking Brake The parking brake is located to the left of the brake pedal, near the driver's door. To set the parking brake, hold the brake pedal down with your right foot. Push down the parking brake pedal with your left foot. To release the parking brake, hold the brake pedal down with your right foot and push the parking brake pedal with your left foot. When you lift your left foot, the parking brake pedal will follow it to the released position. 2-27
