To lessen the risk of
personal injury, do not put
any part of your body under the
vehicle while changing a tire. Do
not start the engine when your
vehicle is on the jack. The jack is
only meant for changing the tire.
Never use the front or rear
differential as a jacking point.
9. Remove the lug nuts with the lug wrench.
10. Replace the flat tire with the spare tire, making sure the valve stem
is facing outward. Reinstall the lug nuts until the wheel is snug against
the hub. Do not fully tighten the lug nuts until the wheel has been
lowered.
11. Lower the wheel by turning the jack handle counterclockwise.
