3. Turn the jack (3) on its side andplace down on the holding
bracket.
4. Reinstall the wing bolt (2) by turning clockwise.
5. To replace the cover, line up the tab at the front of the cover with
the notch in the cover opening.
Push the cover in place and
make sure that the rear clips are
in the slots and push the cover
closed.
Store the center cap or the plastic
bolt-on wheel covers until a full size
tire is put back on the vehicle. When
you replace the compact spare with
a full-size tire, reinstall the bolt-on
wheel covers or the center cap.
Hand-tighten them over the wheel
nuts, using the wrench.Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a
crash and you or others could be
injured. Use only one compact
spare tire at a time.
If this vehicle has a compact spare
tire, it was fully inflated when new;
however, it can lose air over time.
Check the inflation pressure
regularly. It should be 420 kPa
(60 psi).
Stop as soon as possible and check
that the spare tire is correctly
inflated after being installed on the
vehicle. The compact spare tire is
designed for temporary use only. The vehicle will perform differently
with the spare tire installed and it is
recommended that the vehicle
speed be limited to 80 km/h
(50 mph). To conserve the tread of
the spare tire, have the standard tire
repaired or replaced as soon as
convenient and return the spare tire
to the storage area.
When using a compact spare tire,
the ABS and Traction Control
systems may engage until the spare
tire is recognized by the vehicle,
especially on slippery roads. Adjust
driving to reduce possible
wheel slip.
Performance of the All-Wheel
Drive (AWD) system will be
automatically reduced to protect the
system when using the compact
spare. To restore the AWD and
prevent excessive wear on the
clutch in the AWD, replace the
compact spare tire with a full-size
tire as soon as possible.

{Caution
When the compact spare is
installed, do not take the vehicle
through an automatic car wash
with guide rails. The compact
spare can get caught on the rails
which can damage the tire, wheel,
and other parts of the vehicle.
Do not use the compact spare on
other vehicles.
Do not mix the compact spare tire or
wheel with other wheels or tires.
They will not fit. Keep the spare tire
and its wheel together.
{Caution
Tire chains will not fit the compact
spare. Using them can damage
the vehicle and the chains. Do not
use tire chains on the compact
spare.
Jump Starting
For more information about the
vehicle battery, see Battery on
page 10-22.
If the vehicle 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.
{Caution
Ignoring these steps could result
in costly damage to the vehicle
that would not be covered by the
vehicle 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.
{Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.

2. 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 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 an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking brake.
If one of the vehicles is a
four-wheel-drive vehicle, be sure
the transfer case is not in
Neutral.{Caution
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.
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 positive (+) and negative (−)
terminal locations on the other
vehicle. Your vehicle has a remote positive (+) and a remote
negative (−) jump starting
terminal. See
Engine
Compartment Overview on
page 10-5 for 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.

Warning (Continued)
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.
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 blacknegative (−) 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 thenegative (−) cable to the remote
negative (−) terminal of the dead
battery.
Your vehicle has a remote
negative (−) terminal for this
purpose.
10. Now start the vehicle with the good battery and run the
engine for a while.
11. Try to start the vehicle that had the dead battery. If it will not
start after a few tries, it
probably needs service.{Caution
If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct order,
making sure that the cables do
not touch each other or other
metal.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.

Towing the Vehicle
{Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty. Do not lash
or hook to the chassis
components—including the front
and rear subframes, suspension
control arms, and links —during
towing and recovery of a disabled
vehicle, or when securing the
vehicle. Use the proper nylon
strap harnesses around the tires
to secure the vehicle.
Have the vehicle towed on a flatbed
car carrier or a wheel lift tow truck.
If a wheel lift tow truck is used, the
drive wheels cannot contact the
road while the vehicle is being
towed. A wheel dolly must be used
to lift all drive wheels off the ground. Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
To tow the vehicle behind another
vehicle for recreational purposes,
such as behind a motor home, see
“Recreational Vehicle Towing”
following.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle
–such as behind 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:
.The towing capacity of the
towing vehicle. Be sure to read
the tow vehicle manufacturer's
recommendations.
.How far the vehicle will be
towed. Some vehicles have
restrictions on how far and how
long they can be towed.
.The proper towing equipment.
See your dealer or trailering
professional for additional advice
and equipment
recommendations.
.If the vehicle is ready to be
towed. Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.

Dinghy Towing
If the vehicle is front-wheel-drive, it
can be dinghy towed from the front.
These vehicles may also be towed
by putting the front wheels on a
dolly. See“Dolly Towing” later in this
section.
If the vehicle is all-wheel-drive, it
can be dinghy towed from the front.
These vehicles can also be towed
by placing them on a platform trailer
with all four wheels off of the
ground. These vehicles cannot be
towed using a dolly. For vehicles being dinghy towed,
the vehicle should be run at the
beginning of each day and at each
RV fuel stop for about five minutes.
This will ensure proper lubrication of
transmission components. Reinstall
the fuse to start the vehicle.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle to be towed,
shift the transmission to
P (Park), and turn the ignition to
LOCK/OFF.
2. Secure the vehicle to the towing vehicle.
3. Set the parking brake.
4. Turn the ignition to ACC/ ACCESSORY.
5. Shift the transmission to N (Neutral). 6. To prevent the battery from
draining while the vehicle is
being towed, remove the 15 amp
ECM fuse and the 15 amp
Onstar fuse. These are in the
battery compartment behind the
passenger seat on the floor.
Also, remove the 50 amp BATT1
fuse from the underhood fuse
block and store all fuses in a
safe location. See Engine
Compartment Fuse Block on
page 10-28.
7. Release the parking brake.
{Caution
If the vehicle is towed without
performing each of the steps
listed under “Dinghy Towing,” the
automatic transmission could be
damaged. Be sure to follow all
steps of the dinghy towing
procedure prior to and after
towing the vehicle.

different tire sizes on the front of
the vehicle can cause severe
damage to the transmission.
Dolly Towing (All-Wheel-Drive
Vehicles)
All-wheel-drive vehicles must not be
towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on a platform trailer with all four wheels
off of the ground or dinghy towed
from the front.
