    Object Number: 864542  Size: A3

    Rear Flat Tire: Place the jack under the curved rear axle pad. Make sure the jack head is positioned so that the rear axle pad is resting securely on the jack head.

    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.

  13. Turn the ratchet clockwise to raise the vehicle. Raise the vehicle far enough off the ground so there is enough room for the spare tire to clear the ground.

  14. Object Number: 864527  Size: A3

    Remove all the wheel nuts and take off the flat tire.

    Caution: Rust or dirt on a wheel or other parts to which it is fastened, can make the wheel nuts become loose and eventually the wheel could come off and cause a crash. Always remove all rust and dirt from wheels and other parts.

  20. Lower the vehicle by turning the ratchet counterclockwise, with the DOWN mark facing you. Then lower the jack completely.
  21. 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.
