2. Slide the wheel partially under
the vehicle and install the retainer
through the wheel center. If
equipped, you may have to remove
the wheel center cap prior to
pushing the retainer through the
center of the wheel. To remove the
center cap, press it off with the jack
tool from the inner side of the
wheel. Pull on the cable to align the
components at the end of the cable.
3. Assemble the jack handle and winch extension (as shown in
illustration), then insert the winch extension through the access hole
behind the third row seat and engage the winch.
4. Turn the jack handle clockwise until the tire is raised to its stowed
position underneath the vehicle. The wrench will become harder to turn
and the spare tire winch will ratchet or slip when the tire is raised to
maximum tightness. A clicking sound will be heard from the winch
indicating that the tire is properly stowed.
5. Disassemble the jack tool and winch extension and snap them back
into the tool tray.
6. Reinstall the jack bag properly around the jack and tool assembly tray,
making sure the strap is securely fastened.
7. Close the access hole with the rubber plug.
8. Reinstall the tray into the vehicle and secure it with the wing nut
(turn clockwise until tight).
TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
WARNING: When a wheel is installed, always remove any
corrosion, dirt or foreign materials present on the mounting
surfaces of the wheel or the surface of the wheel hub, brake drum or
brake disc that contacts the wheel. Make sure that any fasteners that
attach the rotor to the hub are secured so they do not interfere with
the mounting surfaces of the wheel. Installing wheels without correct
metal-to-metal contact at the wheel mounting surfaces can cause the
wheel nuts to loosen and the wheel to come off while the vehicle is in
motion, resulting in loss of control.
