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 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 5-82
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 below.
To release the spare tire from the secondary latch, do

Spare Tire
Your vehicle, when new, had a fully inated spare tire.
A spare tire may lose air over time, so check its
ination pressure regularly. SeeInation - Tire Pressure
on page 5-58andLoading Your Vehicle on page 4-31
for information regarding proper tire ination and loading
your vehicle. For instructions on how to remove,
install or store a spare tire, seeRemoving the Flat Tire
and Installing the Spare Tire on page 5-73and
Storing a Flat or Spare Tire and Tools on page 5-82.
5-83

After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inated. Have the damaged or at road
tire repaired or replaced as soon as you can and
installed back onto your vehicle. This way, a spare tire
will be available in case you need it again.
Your vehicle may have a different size spare tire than
the road tires — those originally installed on your
vehicle. This spare tire was developed for use on your
vehicle, so it’s all right to drive on it.
If your vehicle has a spare tire that does not match your
vehicle’s original road tires and wheels in size and
type, do not include the spare in the tire rotation.
Appearance Care
Cleaning products can be hazardous. Some are toxic.
Other cleaning products can burst into ames if a match
is struck near them or if they get on a hot part of the
vehicle. Some are dangerous if their fumes are inhaled
in an enclosed space. When anything from a container
is used to clean the vehicle, be sure to follow the
manufacturer’s warnings and instructions. Always open
the doors or windows of the vehicle when cleaning
the inside.Never use these to clean the vehicle:
Gasoline
Benzene
Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
Lacquer Thinner
Nail Polish Remover
They can all be hazardous — some more than
others — and they can all damage the vehicle, too.
Do not use any of these products unless this manual
says you can. In many uses, these will damage the
vehicle:
Alcohol
Laundry Soap
Bleach
Reducing Agents
