CAUTION: If the air is not purged from the power steering system correctly, premature power steering pump failure can result. This condition can
occur on pre-delivery vehicles with evidence of aerated fluid or on vehicles that have had steering component repairs.

prior to any component repair for which power steering noise complaints are accompanied by evidence of aerated fluid.
