10-68 Vehicle Care If needed, finish loosening them with your fingers. The plastic nut caps will not come off. 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 If a Tire Goes Flat on page 10‑65. 2. Turn the wheel wrench counterclockwise once on each wheel nut to loosen it. Do not remove them yet. 3. For all wheel types, find the jacking location using the diagram above and the corresponding jacking notches located on the bottom side of the plastic molding. The notches in the plastic molding are marked with a triangle shape to help you find them. The front location is about 17.7 cm (7.0 in) from the rear edge of the front wheel well. The rear location is about 11.4 cm (4.5 in) from the front edge of the rear wheel well.
