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 if the cable holding
the spare tire is damaged. For the secondary
latch to work, the tire must be stored with the
valve stem pointing up. SeeStoring a Flat or
Spare Tire and Tools on page 488for instructions
on storing the spare or at tire correctly.{CAUTION:
Before beginning this procedure read all
the instructions. Failure to read and follow
the instructions could damage the hoist
assembly and you and others could get
hurt. Read and follow the instructions
listed next.
{CAUTION:
Someone standing too close during the
procedure could be injured by the jack.
If the spare tire does not slide off the jack
completely, make sure no one is behind
you or on either side of you as you pull
the jack out from the under spare.

vehicle to see if the
cable is visible.
If it is not visible,

turning the wheel wrench clockwise until
you hear two clicks or feel it skip twice.
You cannot overtighten the cable.

approximately 6 inches (15 cm) of cable
is exposed.

wheel wrench to the jack and place it under
the vehicle towards the front of the rear
bumper. Position the center lift point of the
