You can raise the vehicle until the front wheels are off the ground. Key on the engine OFF, and turn the steering wheel from stop to stop 12 times. Vehicles equipped with hydro-boost systems or longer-length power steering hoses may require turns up to 15 to 20 stop to stops. Then you can verify the power steering fluid level per operating specification, start the engine, rotate the steering wheel from left to right, check for signs of cavitation or fluid aeration (pump noise/whining), verify the fluid level, and repeat the bleed procedure, if necessary.
