Remove wheel trim; pull trim cap off light-alloy wheels (using puller in vehicle tool kit)
and loosen (but do not remove) the wheel lug nuts. Jack the vehicle up, and place the
car on four stable jack stands or use a professional vehicle lift. We recommend having
two people available for certain steps of the installation.
