wheel could come off and cause an
accident. When you change a wheel,
remove any rust or dirt from the places
where the wheel attaches to the vehicle. In

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. SeeStoring a Flat
or Spare Tire and Tools on page 492.
{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.To release the spare tire from the secondary latch,
do the following:
1. Check under the
vehicle to see if the
cable end is
visible. If the cable
is not visible
proceed to Step 6.
2. If it is visible, rst try to tighten the cable by
turning the wheel wrench clockwise until you
hear two clicks or feel it skip twice. You
cannot overtighten the cable.
3. Loosen the cable by turning the wrench
counterclockwise three or four turns.
4. Repeat this procedure at least two times.
If the spare tire lowers to the ground,
continue with Step 5 ofRemoving the Spare
Tire and Tools on page 478.

edge of the jack (A)
on the wheel
blocks (B),
