If your vehicle has a wheel cover, remove it byusing the flat endof the wheel wrench. If your vehicle has this aluminum wheel, you may have plastic wheel nut caps. Use the wheel nut wrench to remove the wheel nut caps and to loosen the wheel nuts. Pry along the edge of the wheel cover until it comes off. Be careful, the rim edges may be sharp. Don't try to remove it with your bare hands. Note: When replacing any wheel cover, carefully line up the tire valve stem and the notch in the wheel cover. When reinstalling the decorativenut caps, tighten the caps snuglywith the wheel wrench, then continue one-eighth rotation for steel capsand one-quarter rotation for plastic caps.
