1. Put the tools (D) in the toolbag (E) and place them in the
retaining bracket (C).
2. Tighten down the wing nut (C).
3. Assemble the wheel blocks (B) and jack (G) together with the
wing nut (A) and retaining
bolt (H).
4. Position the jack (G) in the mounting bracket (F). Position
the holes in the base of the
jack (G) onto the pin in the
mounting bracket (F).
5. Return them to their original location in the vehicle. For more
information, refer to “Removing
the Spare Tire and Tools” for
more information.Full-Size Spare Tire
Your vehicle, when new, had a
fully-inflated spare tire. A spare tire
may lose air over time, so check its
inflation pressure regularly. See Tire
Pressure on page 10‑62 and
Vehicle Load Limits on page 9‑17
for information regarding proper tire
inflation and loading your vehicle.
For instruction on how to remove,
install or store a spare tire, see
“Removing the Flat Tire and
Installing the Spare” and“Storing a
Flat or Spare Tire and Tools” under
Tire Changing on page 10‑80.
Notice: If the vehicle has
four-wheel drive and a different
size spare tire is installed, do not
drive in four-wheel drive until
the flat tire is repaired and/or
replaced. The vehicle could be
damaged and the repairs would
not be covered by the warranty.
Never use four-wheel drive when
a different size spare tire is
installed on the vehicle. Your vehicle may have a different
size spare tire than the road tires
originally installed on your vehicle.
This spare tire was developed for
use on your vehicle, so it is all right
to drive on it. If your vehicle has
four-wheel drive and the different
size spare tire is installed, keep the
vehicle in two-wheel drive.
After installing the spare tire on your
vehicle, you should stop as soon as
possible and make sure the spare
tire is correctly inflated. Have the
damaged or flat road tire repaired or
replaced as soon as you can and
installed back onto your vehicle.
This way, the spare tire will be
available in case you need it again.
Do not mix tires and wheels of
different sizes, because they will not
fit. Keep your spare tire and its
wheel together. 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.

Jump Starting
For more information about the
vehicle battery, seeBattery on
page 10‑31.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
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. If you have a vehicle with a diesel engine with two batteries,
you should know before you
begin that, especially in cold
weather, you may not be able to
get enough power from a single
battery in another vehicle to
start your diesel engine. If your
vehicle has more than one
battery, using the battery that is
closer to the starter will reduce
electrical resistance. This is
located on the passenger
side, in the rear of the engine
compartment.

3. Get the vehicles close enoughso the jumper cables can reach,
but be sure the vehicles are not
touching each other. If they are,
it could cause an unwanted
ground connection. 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 you have a four-wheel-drive
vehicle, be sure the transfer
case is in a drive gear, not in
Neutral. Notice:
If any accessories are left
on or plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible,
turn off or unplug all accessories
on either vehicle when jump
starting the vehicle.
4. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all the lamps that are not
needed. This will avoid sparks
and help save both batteries.
And it could save the radio!
5. Open the hood on the other vehicle and locate the
positive (+) and negative (−)
terminal locations on that
vehicle. The positive (+) terminal, is
located under a red plastic cover
at the positive battery post.
To uncover the positive (+)
terminal, open the red plastic
cover.
If your vehicle has a gasoline
engine, the remote negative (−)
terminal is a stud located on
the right front of the engine,
where the negative battery cable
attaches.

If your vehicle has a diesel
engine, the remote negative (−)
terminal is the negative (−) post
on the auxiliary battery on the
driver side of the engine
compartment.
For more information on the
location of the remote
positive (+) and remote
negative (−) terminals,
seeEngine Compartment
Overview on page 10‑6
{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.
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.
6. 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.

Vehicle Care 10-95
Do not connect positive (+) to
negative (−) or you will get a
short that would damage the
battery and maybe other parts
too. And do not connect the
negative (−) cable to the
negative (−) terminal on the
dead battery because this can
cause sparks.
5.3L Engine (4.3L, 4.8L, 6.0L, 6.2Land 6.6L Similar) 7. Connect the red positive (+)
cable to the positive (+) terminal
of the vehicle with the dead
battery.
8. Do not let the other end touch metal. Connect it to the
positive (+) terminal of the
good battery. Use a remote
positive (+) terminal if the
vehicle has one.
9. Now connect the black negative (−) cable to the
negative (−) terminal of the
good battery. Use a remote
negative (−) terminal if the
vehicle has one.
Do not let the other end touch
anything until the next step. 10. Connect the other end of the
negative (−) cable to a heavy,
unpainted metal engine part or
to the remote negative (−)
terminal, on the vehicle with
the dead battery.
11. Start the vehicle with the good battery and run the engine for
a while.
12. Try to start the vehicle that had the dead battery. If it will
not start after a few tries,
it probably needs service.

Towing
Towing the Vehicle
Notice:To avoid damage, the
disabled vehicle should be towed
with all four wheels off the
ground. Care must be taken with
vehicles that have low ground
clearance and/or special
equipment. Always flatbed on a
car carrier.
Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
See Roadside Assistance Program
(U.S. and Canada) on page 13‑7 or
Roadside Assistance Program
(Mexico) on page 13‑9.
To tow the vehicle behind another
vehicle for recreational purposes,
such as behind a motor home, see
“Recreational Vehicle Towing” in this
section.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle, such as a motor home.
The two most common types of
recreational vehicle towing are
known as dinghy towing and dolly
towing. Dinghy towing is towing the
vehicle with all four wheels on the
ground. Dolly towing is towing the
vehicle with two wheels on the
ground and two wheels up on a
device known as a dolly. Here are some important things to
consider before recreational vehicle
towing:.What is the towing capacity
of the towing vehicle?
Be sure to read the tow
vehicle manufacturer's
recommendations.
.What is the distance that will
be travelled? Some vehicles
have restrictions on how far and
how long they can tow.
.Is the proper towing equipment
going to be used? See your
dealer or trailering professional
for additional advice and
equipment recommendations.
.Is the vehicle ready to be
towed? Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.

Dinghy Towing
Two-Wheel-Drive Vehicles
Notice:If the vehicle is towed
with all four wheels on the
ground, the drivetrain
components could be damaged.
The repairs would not be covered
by the vehicle warranty. Do not
tow the vehicle with all four
wheels on the ground.
Two-wheel-drive vehicles
should not be towed with all
four wheels on the ground. Two-wheel-drive transmissions
have no provisions for internal
lubrication while being towed.
Four-Wheel-Drive Vehicles
Use the following procedure to
dinghy tow a four-wheel-drive
vehicle:
1. Position the vehicle being towed
behind the tow vehicle and shift
the transmission to P (Park).
2. Turn the engine off and firmly set the parking brake. 3. Securely attach the vehicle
being towed to the tow vehicle.
{WARNING
Shifting a four-wheel-drive
vehicle's transfer case into
N (Neutral) can cause the vehicle
to roll even if the transmission is
in P (Park). The driver or others
could be injured. Make sure the
parking brake is firmly set before
the transfer case is shifted to
N (Neutral).
4. Shift the transfer case to N (Neutral). See “Shifting into
Neutral” underFour-Wheel Drive
on page 9‑45 for the proper
procedure to select the Neutral
position for the vehicle.
5. Release the parking brake only after the vehicle being towed is
firmly attached to the towing
vehicle.
