Secondary Latch System
This 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. See
“Storing a Flat or Spare Tire and
Tools”underTire Changing on
page 10‑64.
{WARNING
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:
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, first 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 under “Removing the
Spare Tire and Tools” underTire
Changing on page 10‑64.
5. If the spare does not lower, turn the wrench counterclockwise
until approximately 15 cm (6 in)
of cable is exposed.
6. Stand the wheel blocks on their shortest ends, with the backs
facing each other.

12. Lower the jack by turningthe wheel wrench
counterclockwise. Keep
lowering the jack until the
spare tire slides off the jack or
is hanging by the cable.
{WARNING
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
under the spare.
13. Disconnect the jack handle from the jack and carefully
remove the jack. Use one hand
to push against the spare while
firmly pulling the jack out from
under the spare tire with the
other hand. If the spare tire is hanging from
the cable, insert the hoist end
of extension, and wheel
wrench into the hoist shaft hole
in the bumper and turn the
wheel wrench counterclockwise
to lower the spare the rest of
the way.
14. Turn the wheel wrench in the hoist shaft hole in the bumper
clockwise to raise the cable
back up if the cable is hanging
under the vehicle.
Have the hoist assembly inspected
as soon as you can. You will not be
able to store a spare or flat tire
using the hoist assembly until it has
been inspected and/or replaced.
To continue changing the flat tire,
see “Removing the Flat Tire and
Installing the Spare Tire” underTire
Changing on page 10‑64.
Full-Size Spare Tire
The full-size spare tire that came
with the vehicle was fully inflated
when new, however, it can lose air over time. Check the inflation
pressure regularly. See
Tire
Pressure on page 10‑49 and
Vehicle Load Limits on page 9‑16
for information regarding proper tire
inflation and loading the vehicle.
For instructions on how to remove,
install, or store a spare tire, see Tire
Changing on page 10‑64.
After installing the spare tire on the
vehicle, stop as soon as possible
and check that the spare is correctly
inflated. The spare tire is made
to perform well at speeds up to
112 km/h (70 mph) at the
recommended inflation pressure,
so you can finish your trip.
Have the damaged or flat road tire
repaired or replaced and installed
back onto the vehicle as soon as
possible so the spare tire will be
available in case it is needed again.
Do not mix tires and wheels of
different sizes, because they will not
fit. Keep the spare tire and its wheel
together.

Jump Starting
For more information about the
vehicle battery, seeBattery on
page 10‑27.
If the vehicle's battery (or batteries)
has run down, you may want to use
another vehicle and some jumper
cables to start your vehicle. Be sure
to use the following steps to do it
safely.
{WARNING
Batteries can hurt you. They can
be dangerous because:
.They contain acid that can
burn you.
.They contain gas that can
explode or ignite.
.They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you. Notice:
Ignoring these steps
could result in costly damage to
the vehicle that would not be
covered by the warranty.
Trying to start the vehicle by
pushing or pulling it will not
work, and it could damage the
vehicle.
1. Check the other vehicle. It must
have a 12-volt battery with a
negative ground system.
Notice: Only use a vehicle that
has a 12-volt system with a
negative ground for jump
starting. If the other vehicle does
not have a 12-volt system with a
negative ground, both vehicles
can be damaged. 2. Get the vehicles close enough
so the jumper cables can reach,
but be sure the vehicles are
not touching each other. If they
are, it could cause a ground
connection you do not want.
You would not be able to start
your vehicle, and the bad
grounding could damage the
electrical systems.
To avoid the possibility of the
vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put the automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking brake.
If either vehicle has
four-wheel-drive, be sure the
transfer case is in a drive gear,
not in Neutral.

{WARNING
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing and tools away from any
underhood electric fan.
{WARNING
Using an open flame near a
battery can cause battery gas to
explode. People have been hurt
doing this, and some have been
blinded. Use a flashlight if you
need more light.(Continued)
WARNING (Continued)
Be sure the battery has enough
water. You do not need to add
water to the battery installed in
your new vehicle. But if a battery
has filler caps, be sure the right
amount of fluid is there. If it is low,
add water to take care of that
first. If you do not, explosive gas
could be present.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.
{WARNING
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.
5. Check that the jumper cables do not have loose or missing
insulation. If they do, you could
get a shock. The vehicles could
be damaged too.
Before you connect the cables,
here are some basic things you
should know. Positive (+) will go
to positive (+) or to a remote
positive (+) terminal if the vehicle
has one. Negative (−) will go to a
heavy, unpainted metal engine
part or to a remote negative (−)
terminal if the vehicle has one.
