Locking Rear Axle It canbe dangerous toget out of your vehicle if the shiftlever is not fully in PARK (P) with the parking brake firmly set. Your vehiclecan roll. Don't leave your vehicle whenthe engine is running unless you have to. If' you've left the engine running, thevehicle can move suddenly. You or others could be injured. To be sure your vehicle won't move, even when you're on fairly level ground, always set your parkingbrake and move the shiftlever to PARK (P). Follow the proper steps to be sure your vehicle won't move. See "Shifting Into PARK (P)" i n the Index. If you're pulling a trailer, see "Towing a Trailer" in the Index. 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. 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. 2-24
