Your vehicle has an underbody mounted tire hoist assembly that has a secondary latch system. It is designed to stop the compact spare tire from suddenly falling off your vehicle if the cable holding the spare tire is damaged. For the secondary latch to work, the tire must be stowed with the valve stem pointing down. See Storing a Flat or Spare Tire and Tools for instructions on storing the spare tire correctly.

Caution: Before beginning this procedure read all the instructions. Failure to read and follow the instructions could damage the hoist assembly and you and others could get hurt. Read and follow the instructions listed next.

Caution: Someone standing too close during the procedure could be injured by the jack. If the spare tire does not slide off the jack completely, make sure no one is behind you or on either side of you as you pull the jack out from under the spare.

To release the spare tire from the secondary latch:

  1. If the cable is not visible, start this procedure at Step 3.

Have the hoist assembly inspected as soon as you can. You will not be able to store a spare tire using the hoist assembly until it has been repaired or replaced.
