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 put in FIRST (1), the transmission won't shift into first gear until the vehicle is going slowly enough. Parking Brake To set the parking brake, hold the regular brake pedal down with your right foot. Push down the parking brake pedal with your left foot. If the ignition is on, the brake system warning light will come on. NOTICE: If your rear wheels can't rotate, don't try to drive. This might happen if you are stuck in very deep sand or mud or are up against a solid object. You could damage your transmission. Also, if you stop when going uphill, don't hold your vehicle there with only the accelerator pedal. This could overheat and damage the transmission. Use your brakes or shift into PARK (P) to hold your vehicle in position on a hill. To release the parking brake, hold the regular brake pedal down. Pull the handle, located just above the parking brake pedal, marked BRAKE RELEASE to release the parking brake. 2-27
