Removing the Flat Tire and Installing the Spare Tire This vehicle may have aluminum wheels with exposed wheel nuts. Use the wheel wrench to loosen all the wheel nuts. Do not remove them yet. Or, this vehicle may have steel wheels with plastic covers. If needed, use the flat end of the wheel wrench and pry along the edge of the cover until it comes off. The edge of the wheel cover could be sharp, so do not try to remove it with your bare hands. Do not drop the cover or lay it face down, as it could become scratched or damaged. Store the wheel cover in the trunk until the flat tire is repaired or replaced. Once you have removed the wheel cover, use the following procedure to remove the flat tire and install the spare tire. 1. Do a safety check before proceeding. See Changing a Flat Tire on page 5-76 To remove the plastic covers and wheel nut caps, loosen the plastic nut caps with the wheel wrench in a counterclockwise direction. If needed, finish loosening them with your fingers. The plastic nut caps will not come off. 2. Turn the wheel wrench counterclockwise once on each wheel nut to loosen them. Do not remove them yet. 5-79
