2. Use the wheel wrench to loosen the plastic
wheel nut caps, if the vehicle has them, in a
counterclockwise direction.
If needed, finish loosening them by hand.
The nut caps will not come off of the wheel
cover.
3. Use the flat end of the wheel wrench and pry
along the edge of the cover until it comes off.
Pull off the wheel cover and set it aside.
The edge of the wheel cover could be sharp,
so do not try to remove the cover with your
bare hands. Do not drop the cap or lay it face
down, as it could become scratched or
damaged.
If the vehicle has aluminum wheels and wheel
center caps, the wheel nuts are hidden behind the
center cap. Remove the center cap by using
the flat end of the wheel wrench at the notch.
Do not drop the cap or lay it facedown, as it could
become scratched or damaged.

Once you have removed the wheel cover or
center cap, use the following procedure to remove
the flat tire and install the spare tire.

1. Place the wheel wrench securely over
the wheel nut. Turn the wheel wrench
counterclockwise to loosen all the wheel
nuts, but do no remove them yet.
2. Turn the jack handle clockwise to raise
the jack lift head.
