USING 4-WHEEL DRIVE (4WD) (if so equipped) WARNING ● For 4WD equipped vehicles, do not attempt to raise 2 wheels off the ground and shift the transmission to any drive or reverse position with the engine running. Doing so may result in drivetrain damage or unexpected vehicle movement which could result in serious vehicle damage or personal injury. ● Do not attempt to test a 4WD equipped vehicle on a 2-wheel dynamometer, or similar equipment even if the other 2 wheels are raised off the ground. Make sure you inform test facility personnel that your vehicle is equipped with 4WD before it is placed on a dynamometer. Using the wrong test equipment may result in drivetrain damage or unexpected vehicle movement which could result in serious vehicle damage or personal injury.
