FIRST (1): This position gives you even more power (but lowerfuel economy) than SECOND (2).You can use it on very steep hills, or in deep snow or mud. If the shift lever isput in FIRST (l),the transmission won't shift into first gear until the vehicle is going slowly enough. Limited-Slip Rear Axle (Option) If you have this feature, your rearaxle 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 other does, the the limited-slip feature will allowthe wheel with traction to move the vehicle. I NOTICE: If your rearwheels can'trotate, don'ttry to drive. This might happenif 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 your vehicle there withonly the accelerator pedal. This could overheat and damage thetransmission. Use your brakes orshift 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 yourright foot. Push down the parking brake pedal with your left foot. If the ignition is on, the brake system warning light will comeon. 2-21
