Secondary Latch System

Your vehicle has an underbody-mounted tire hoist
assembly equipped with a secondary latch system. It is
designed to stop the spare tire from suddenly falling
off your vehicle. For the secondary latch to work,
the spare must be installed with the valve stem pointing
down. See Storing a Flat or Spare Tire and Tools on
page 5-88.
CAUTION:

Before beginning this procedure read all the
instructions. Failure to read and follow the
