Secondary Latch System
This vehicle has an underbody
mounted tire hoist assembly that
has a secondary latch system. It is
designed to stop the compact spare
tire from suddenly falling off the
vehicle if the cable holding the spare
tire is damaged. For the secondary
latch to work, the tire must be stowed
with the valve stem pointing down.
SeeStoring a Flat or Spare Tire and
Tools on page 5-78for instructions
on storing the spare 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.To release the spare tire from the
secondary latch:
{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.
1. If the cable is not visible, start
this procedure at Step 3.2. Turn the lug wrench
counterclockwise until
approximately 6 inches
(15 cm) of cable is exposed.
3. Attach the lug wrench to the
jack and raise the jack at
least 10 turns.
4. Place the jack under the vehicle,
ahead of the rear bumper.
Position the center lift point of
the jack under the center of

Tire and Tools
Storing the Spare Tire
{CAUTION
The underbody-mounted spare
tire needs to be stored with the
valve stem pointing down. If the
spare tire is stored with the valve
stem pointing upwards, the
secondary latch will not work
properly and the spare tire could
loosen and suddenly fall from the
vehicle. If this happened when the
vehicle was being driven, the tire
might contact a person or another
vehicle, causing injury and
damage to itself. Be sure the
underbody-mounted spare tire
is stored with the valve stem
pointing down.
{CAUTION
Storing a jack, a tire, or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store all these in
the proper place.
To store the spare tire:
1. Lay the compact spare tire near
the rear of the vehicle with the
valve stem down.
2. Reinstall the plastic spare tire
heat shield on the compact
spare tire.3. Slide the cable retainer through
the center of the wheel and start
to raise the compact spare tire.
Make sure the retainer is fully
seated across the underside of
the wheel.
4. When the compact spare tire is
almost in the stored position,
turn the tire so the valve is
toward the rear of the vehicle.
This position helps when
checking the air pressure in
the compact spare tire.
5. Raise the tire fully against the
underside of the vehicle. Continue
turning the lug wrench until you
feel more than two clicks. This
indicates that the compact spare
tire is secure and the cable is
tight. The spare tire hoist cannot
be overtightened.
