I f there is a wheel cover, loosen the nut caps with the
wheel wrench. They won't come off. Then, using the
flat end of the wheel wrench, pry along the edge of the
wheel cover until it comes off. Be careful; the edge may
be sharp. Don't try to remove the cover with your bare
hands.
If your vehicle has wheel
nut caps, remove them
using the wheel wrench.
