2. Insert the hoist end (chiseled end) of the extension
tool through the hole in the rear bumper and into
the funnel-shaped guide. The chiseled end of
the extension is used to lower the spare tire.
3. Turn the wheel wrench (D) 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.
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” later in this
section.
4. When the tire has been
lowered, tilt the retainer
and slide it up the
cable so it can
be pulled up through
the wheel opening.
5. Put the spare tire near the flat tire.
