handle extension (B), jack handle (C), wheel wrench (D)

Your spare tire is stored underneath the rear of your

ratchet (E) to lower the spare tire from the vehicle.
To lower the spare tire from the vehicle, do the following:

2. Put the flat chisel end of the wheel wrench on an
angle through the hole between the body and the
