{CAUTION
Over-inating a tire could cause
the tire to rupture and you or
others could be injured. Be sure
to read and follow the tire sealant
and compressor kit instructions
and inate the tire to its
recommended pressure. Do not
exceed the recommended
pressure.
{CAUTION
Storing the tire sealant and
compressor kit 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 the tire sealant and
compressor kit in its original
location.
If this vehicle has a tire sealant and
compressor kit, there may not be a
spare tire, tire changing equipment,
and on some vehicles there may not
be a place to store a tire.The tire sealant and compressor
can be used to temporarily seal
punctures up to
14inch (6 mm) in the
tread area of the tire. It can also be
used to inate an under inated tire.
If the tire has been separated from
the wheel, has damaged sidewalls,
or has a large puncture, the tire
is too severely damaged for the tire
sealant and compressor kit to be
effective. SeeRoadside Assistance
Program on page 7-6.
Read and follow all of the tire
sealant and compressor kit
instructions.

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 5-80
for 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

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.
