Locking Rear Axle If your vehicle has this feature, your locking 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, this feature will allow the wheel with traction to move the vehicle. Tilt Wheel The tilt steering wheel allows you to adjust the steering wheel before you drive. Horn To sound the horn, press the center pad on the steering wheel. You can also raise it to the highest level to give your legs more room when you enter and exit the vehicle. To tilt the wheel, hold the steering wheel and pull the lever. Move the steering wheel to a comfortable level, then release the lever to lock the wheel in place. 2-51
