Storing the Spare Tire

Caution: The underbody-mounted spare tire needs to be stored with the valve stem pointing down. If the spare tire is stored with the valve stem pointing upwards, the secondary latch will not work properly and the spare tire could loosen and suddenly fall from the vehicle. If this happened when the vehicle was being driven, the tire might contact a person or another vehicle, causing injury and damage to itself. Be sure the underbody-mounted spare tire is stored with the valve stem pointing down.

Caution: Storing a jack, a tire, or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.

To store the spare tire:

  1. Lay the compact spare tire near the rear of the vehicle with the valve stem down.
  2. Reinstall the plastic spare tire heat shield on the compact spare tire.
  3. Slide the cable retainer through the center of the wheel and start to raise the compact spare tire.
  4. Make sure the retainer is fully seated across the underside of the wheel.

  5. When the compact spare tire is almost in the stored position, turn the tire so the valve is toward the rear of the vehicle.
  6. This position helps when checking the air pressure in the compact spare tire.

  7. Raise the tire fully against the underside of the vehicle. Continue turning the lug wrench until you feel more than two clicks. This indicates that the compact spare tire is secure and the cable is tight. The spare tire hoist cannot be overtightened.

  9. Make sure the tire is stored securely. Push, pull (A), and then try to turn (B) the tire. If the tire moves, use the lug wrench to tighten the cable.

Storing the Flat Tire

Notice: Storing the full-size flat tire in the underbody hoist system can expose it to heat from the exhaust system. This can damage the tire and underbody hoist system. Do not store the full-size flat tire in the underbody hoist system.

  1. Remove the cable package from the jack storage area.
  2. Remove the small center cap by tapping the back of the cap with the extension of the shaft, if the vehicle has aluminum wheels.
  3. Put the flat tire in the rear storage area with the valve stem pointing toward the rear of the vehicle.

  4. Object Number: 1812200  Size: B3
  5. Hook one end of the cable onto the outside portion of the liftgate hinge opposite (B).
  6. Pull the cable (A) through the center of the wheel (D), then the door striker (E), and the spare tire heat shield (C).

  7. Object Number: 812750  Size: A2
  8. Hook the other end of the cable onto the outer portion of the liftgate hinge (B).
  9. Pull on the cable to make sure it is secure.
  10. The metal tube should be centered at the striker.

  11. Object Number: 812751  Size: A2
  12. Push the tube toward the front of the vehicle.
  13. Close the liftgate and latch it properly.

Storing the Tools


Object Number: 1707031  Size: B3
  1. Tool Bag

  2. Wing Bolt

  3. Jack

Put back all tools as they were stored in the jack storage compartment and put the compartment cover back on.

  1. Attach the tool bag to the jack.
  2. Make sure that the bottom of the jack is facing toward you.
  3. Turn the jack (C) on its side and place it down on the holding bracket.
  4. Reinstall the wing bolt (B) by turning it clockwise.
  5. To replace the cover, line up the tabs on the bottom of the cover with the slots in the cover opening. Push the cover in place, insuring that the upper front and rear tabs are in the opening and push the cover closed. The center latch should be fully engaged. This secures the cover in place.

Store the center cap or the plastic bolt-on wheel covers until a full size tire is put back on the vehicle. When you replace the compact spare with a full-size tire, reinstall the bolt-on wheel covers or the center cap. Hand-tighten them over the wheel nuts, using the lug wrench.
