  8. Position the jack lift head at the jack location nearest the flat tire. The front location is about 8 inches (20 cm) behind the front wheel opening. The rear location is about 4 inches (10 cm) in front of the rear wheel opening.
  9. Raise the jack head until it fits firmly in the vehicle's frame, where the notch is located, nearest the flat tire.
  10. Put the compact spare tire near the flat tire.
  11. 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.

  12. Turn the jack handle clockwise to raise the vehicle. Raise the vehicle far enough off the ground so there is enough room for the compact spare tire to fit under the vehicle.

  14. Remove all of the wheel nuts.
  15. 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 .

    Remove any rust or dirt from the wheel bolts, mounting surfaces, and spare wheel.

  16. Place the compact spare tire on the wheel-mounting surface.
  17. Caution: Never use oil or grease on bolts or nuts because the nuts might come loose. The vehicle's wheel could fall off, causing a crash.

  18. Reinstall the wheel nuts with the rounded end of the nuts toward the wheel. Tighten each nut clockwise by hand until the wheel is held against the hub.
  19. Lower the vehicle by turning the jack handle counterclockwise. Lower the jack completely.
  20. 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.
