10-84 Vehicle Care
Secondary Latch System
This vehicle has an underbody
mounted tire hoist assembly that
has 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.
SeeTire Changing (H3T)
on
page 10‑66or Tire Changing (H3)on page 10‑75for instructions on
storing the spare tire correctly.
{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:
{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.
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 the
spare tire.

10-86 Vehicle Care
After installing the spare tire on your
vehicle, you should stop as soon as
possible and make sure the spare is
correctly inflated.
The spare tire does not have a Tire
Pressure Monitor System sensor.
You may get a low pressure warning
light. SeeTire Pressure Monitor
Operation
on page 10‑53. Have the
damaged or flat road tire repaired or
replaced as soon as you can.
Do not mix tires and wheels of
different sizes, because they will
not fit. Keep your spare tire and its
wheel together.
Jump Starting
If the vehicle's battery 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: If the other vehicle's
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle.
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.

Vehicle Care 10-87
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 an 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 not in Neutral.
Notice: If you leave the radio or
other accessories on during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories
when jump starting the vehicle. 3. 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 lamps that are not
needed. This will avoid sparks
and help save both batteries.
And it could save the radio!
4. Open the hoods and locate the batteries on both vehicles. You
will use the positive (+) battery
terminal and the remote
negative (−) jump starting
terminal to jump start your
vehicle. To access the
positive (+) battery terminal,
open the terminal cover. See
Engine Compartment Overview
on page 10‑6for more
information on the terminal
locations.
{WARNING
Using a match 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 batteries have
enough water. You do not need
to add water to the ACDelco
®
battery (or batteries) 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.

10-88 Vehicle Care
{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. 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.
6. Connect the red positive (+) cable to the positive (+) terminal
of the dead battery. Use a
remote positive (+) terminal if the
vehicle has one.
7. 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.
8. 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. The
other end of the negative (−)
cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part,
or to a remote negative (−)
terminal on the vehicle with the
dead battery.
9. Connect the other end of the negative (−) cable at least
18 inches (45 cm) away from
the dead battery, but not near
engine parts that move. The
electrical connection is just as
good there, and the chance of
sparks getting back to the
battery is much less.
Your vehicle has a remote
negative (−) terminal, marked
GND (Ground), for this purpose.

Vehicle Care 10-91
Use the following procedure to tow
the vehicle:
1. Put the transmission in P (Park)for an automatic transmission
or in 1 (First) for a manual
transmission.
2. Turn the engine off, but leave the ignition in ACC/
ACCESSORY.
3. Firmly set the parking brake.
4. Securely attach the vehicle being towed to the tow vehicle.
{WARNING
Shifting a full‐time four‐wheel‐
drive vehicle's transfer case into
N (Neutral) can cause the vehicle
to roll even if the automatic
transmission is in P (Park) or the
manual transmission is in any
gear. You or others could be
injured. Make sure the parking
brake is firmly set before the
transfer case is shifted to
N (Neutral). 5. Shift the transfer case to
N (Neutral). See Four-Wheel
Drive
on page 9‑46for the
proper procedure to select the
N (Neutral) position for the
vehicle.
6. Release the parking brake only after the vehicle being towed
is firmly attached to the tow
vehicle.
7. Make sure the ignition is in ACC/ACCESSORY.
When towing the vehicle for
extended periods of time, start the
vehicle as often as possible to
prevent battery drain. This should
only be done when the tow vehicle
is parked.
After towing, see “Shifting Out of
NEUTRAL” underFour-Wheel Drive
on page 9‑46.
Dolly Towing
Notice: Dolly towing the
vehicle will damage drivetrain
components. Do not dolly tow the
vehicle.
The vehicle cannot be dolly towed.
If the vehicle must be towed behind
another vehicle, use the dinghy
towing procedure explained
previously.

10-98 Vehicle Care
A paper towel can be used to blot
excess moisture from the fabric or
carpet after the cleaning process.
Leather
To remove dust, a soft cloth
dampened with water can be used.
If a more thorough cleaning is
necessary, a soft cloth dampened
with a mild soap solution can be
used. Allow the leather to dry
naturally. Do not use heat, steam,
or spot lifters or spot removers,
or shoe polish on leather. Many
commercial leather cleaners
and coatings that are sold to
preserve and protect leather
may permanently change the
appearance and feel of the leather
and are not recommended. Do
not use silicone or wax-based
products, or those containing
organic solvents to clean the
vehicle's interior because they can
alter the appearance by increasing
the gloss in a non-uniform manner.
Instrument Panel, Vinyl, and
Other Plastic Surfaces
To remove dust, a soft cloth
dampened with water can be used.
If a more thorough cleaning is
necessary, a clean soft cloth
dampened with a mild soap solution
can be used to gently remove dust
and dirt. Never use spot lifters or
removers on plastic surfaces.
Many commercial cleaners and
coatings that are sold to preserve
and protect soft plastic surfaces
may permanently change the
appearance and feel of the interior
and are not recommended. Do
not use silicone or wax-based
products, or those containing
organic solvents to clean the
vehicle's interior because they can
alter the appearance by increasing
the gloss in a non-uniform manner.Some commercial products may
increase gloss on the instrument
panel. The increase in gloss may
cause annoying reflections in the
windshield and even make it difficult
to see through the windshield under
certain conditions.
Care of Safety Belts
Keep belts clean and dry.
{WARNING
Do not bleach or dye safety belts.
It may severely weaken them. In
a crash, they might not be able
to provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.

Rotation of New Tires
To maintain ride, handling, and
performance of the vehicle, it is
important that the first rotation
service for new tires be performed
when they have 8 000 to 13 000 km
(5,000 to 8,000 miles). See Tire
Rotation on page 10‑57.
Scheduled
Maintenance
