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 selector lever is put in FIRST (1) while the vehicle is moving forward, the transmission won't shift into first gear until the vehicle is going slowly enough. Shift Lock Release This vehicle is equipped with a shift lock release system. If your vehicle has a dead battery and you need to have your vehicle towed, there is a shift lock release lever that will allow you to move the shift lever out of PARK (P). To access the shift lock release lever, do the following: 1. Press on the sides of the boot around the shift lever to release the boot. 2. Lift up the boot on the shift lever and you will see an orange lever. 3. Press the orange lever down and move the shift lever out of PARK (P). 4. Snap the shift lever boot back in place. NOTICE: If your rear wheels can't rotate, don't try to drive. This might happen if you were stuck in very deep sand or mud or were up against a solid object. You could damage your transmission. Also, if you stop when going uphill, don't hold the vehicle there with only the accelerator pedal. This could overheat and damage the transmission. Use the brakes or shift into PARK (P) to hold the vehicle in position on a hill. 2-25
