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.

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

  5. 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.
  6. The front location is about 7.0 inches (17.7 cm) from the rear edge of the front wheel well. The rear location is about 4.5 inches (11.4 cm) from the front edge of the rear wheel well.

  7. Put the compact spare tire near you.
  8. Caution: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack.

    Caution: Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle.

    Caution: Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. If a jack is provided with the vehicle, it is designed only for changing a flat tire. If it is used for anything else, you or others could be badly injured or killed if the vehicle slips off the jack. If a jack is provided with the vehicle, only use it for changing a flat tire.

  9. Raise the vehicle by turning the jack handle clockwise. Raise the vehicle far enough off the ground to install the compact spare tire.
  10. Remove all wheel nuts and the flat tire.
  11. Caution: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after time. The wheel could come off and cause an accident. When changing a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off. See Changing a Flat Tire .

  16. Lower the vehicle by turning the jack handle counterclockwise. Lower the jack completely.
  17. Caution: Incorrect or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to a crash. If you have to replace them, be sure to get new original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See Capacities and Specifications for wheel nut torque specification.

    Notice: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. See Capacities and Specifications for the wheel nut torque specification.
