You can also use SECOND (2) for starting your vehicle from a stop on slippery road surfaces. 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 (1) until the vehicle is going slowly enough. Locking Rear Axle Your rear axle can give you additional traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when one of the rear wheels has no traction and the other does, the locking feature will allow the wheel with traction to move the vehicle. All-Wheel Drive Your engine's driving power is sent to all four wheels for extra traction. All-wheel drive is like four-wheel drive, but there is no lever or switch to engage or disengage the front axle. It is fully automatic and adjusts itself as needed for road conditions. NOTICE: If your rear wheelscan'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 yourtransmission. 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. 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. To release the parking brake, hold the regular brake pedal down. 2-18
