Vehicle Care 1. Open the hoist shaft access cover on the bumper to access the spare tire lock (J). 2. To remove the spare tire lock, insert the ignition key, turn it clockwise and pull it straight out. 10-69 If the spare tire does not lower to the ground, the secondary latch is engaged causing the tire not to lower. See Secondary Latch System on page 10‑77 for more information. 4. Insert the open end of the extension (F) through the hole in the rear bumper (G) (hoist shaft access hole). Be sure the hoist end (F) of the extension connects to the hoist shaft. The ribbed square end of the extension is used to lower the spare tire. Do not use the chiseled end of the wheel wrench. 5. Turn the wheel wrench counterclockwise to lower the spare tire to the ground. Continue to turn the wheel wrench until the spare tire can be pulled out from under the vehicle. 6. Use the wheel wrench hook to pull the hoist cable closer to assist in reaching the spare tire. 3. Assemble the two jack handle extensions (I) and wheel wrench (H), as shown.
