Rear Position
Rear Alternative Position (DieselVehicles) 4. Position the jack under the
vehicle, as shown.
The front position jacking point is
on the frame. The rear position
jacking point is on the rear axle.
If the exhaust system interferes
with the jack location in the rear
axle, such as in Diesel vehicles,
place the jack (1) on the rear
axle between the axle housing
and the shock absorber bracket
in order to avoid any
interference with the exhaust
pipe (2).
{Warning
Getting under a vehicle when it is
jacked up is dangerous. If the
vehicle slips off the jack you could
be badly injured or killed. Never
get under a vehicle when it is
supported only by a jack.
{Warning
Raising the vehicle with the jack
improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack lift
head into the proper location
before raising the vehicle.
5. Turn the wheel wrench clockwise to raise the vehicle.
Raise the vehicle far enough off
the ground so there is enough
room for the spare tire to fit.

6. Remove all the wheel nuts.
7. Take the flat tire off of themounting surface.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
(Continued)
Warning (Continued)
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
8. Remove any rust or dirt from thewheel bolts, mounting surfaces,
and spare wheel.
{Warning
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.
9. Put the wheel nuts back on withthe rounded end of the nuts
toward the wheel. Tighten each
wheel nut by hand until the
wheel is held against the hub.

10. Turn the jack handlecounterclockwise to lower the
vehicle. Lower the jack
completely.
{Warning
Wheel nuts that are not tight can
work loose. If all the nuts on a
wheel come off, the wheel can
come off the vehicle, causing a
crash. All wheel nuts must be
properly tightened. Follow the
rules in this section to be sure
they are.
{Warning
If wheel studs are damaged, they
can break. If all the studs on a
wheel broke, the wheel could
come off and cause a crash.
If any stud is damaged because
of a loose-running wheel, it could
be that all of the studs are
(Continued)
Warning (Continued)
damaged. To be sure, replace all
studs on the wheel. If the stud
holes in a wheel have become
larger, the wheel could collapse in
operation. Replace any wheel if
its stud holes have become larger
or distorted in any way. Inspect
hubs and hub‐piloted wheels for
damage. Because of loose
running wheels, piloting pad
damage may occur and require
replacement of the entire hub, for
proper centering of the wheels.
When replacing studs, hubs,
wheel nuts or wheels, be sure to
use GM original equipment parts.
{Warning
Wheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or(Continued)
Warning (Continued)
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. SeeCapacities and
Specifications on page 12-2 for
original equipment wheel nut
torque specifications.
{Caution
Improperly tightened wheel nuts
can lead to brake pulsation and
rotor damage. To avoid expensive
brake repairs, evenly tighten the
wheel nuts in the proper
sequence and to the proper
torque specification.

wheel wrench clockwise and in
a crisscross sequence, as
shown. 12. Put the wheel cover or the
center cap and plastic wheel
nut caps back on. Remove any
wheel blocks.
Have a technician check the
wheel nut tightness of all
wheels with a torque wrench
after the first 160 km (100 mi)
and then 1 600 km (1,000 mi)
after that. Repeat this service
whenever a tire is removed or
serviced. See Capacities and
Specifications on page 12-2 for
more information.
Storing a Flat or Spare Tire
and Tools
{Warning
Storing a jack, a tire, or other
equipment in the passenger
compartment of the vehicle could
cause injury. In a sudden stop or
collision, loose equipment could
strike someone. Store all these in
the proper place. 1. Put the tire on the ground at the
rear of the vehicle with the valve
stem pointed down.
2. Pull the retaining bar through the
center of the wheel, making sure
it is properly attached.
3. Pull the wheel toward the rear of the vehicle, keeping the cable
tight.
4. Open the passenger side rear door.
5. Insert the chisel end of the hoist handle, on an angle, through the
hole in the rear floor panel
above the bumper.

6. Turn the wheel wrenchclockwise to fully raise the tire
against the underside of the
vehicle. Continue turning the
wheel wrench until the tire is
secure and the cable is tight.
Two clicks should occur. The
spare tire hoist cannot be
overtightened.7. Make sure the tire is storedsecurely. Push, pull (1), and then
try to turn (2) the tire. If the tire
moves, use the wheel wrench to
tighten the cable.
Two clicks mean the tire is up all
the way.
8. Return the jacking equipment to the proper location. Secure the
items and replace the jack cover.
Full-Size Spare Tire
If this vehicle came with a full-size
spare tire, it was fully inflated when
new, however, it can lose air over
time. Check the inflation pressure
regularly. See Tire Pressure on
page 10-51 andVehicle Load Limits
on page 9-9. For instructions on
how to remove, install, or store a
spare tire, see Tire Changing on
page 10-66.
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 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
Jump Starting - North
America
For more information about the
vehicle battery, seeBattery - North
America on page 10-25.
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
WARNING: Battery posts,
terminals, and related
accessories contain lead and lead
compounds, chemicals known to
the State of California to cause
cancer and birth defects or other
reproductive harm. Batteries also
contain other chemicals known to
the State of California to cause
(Continued)
Warning (Continued)
cancer.WASH HANDS AFTER
HANDLING. SeeCalifornia
Proposition 65 Warning on
page 10-2.
{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.
{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
(Continued)
Caution (Continued)
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 outlet. 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 of the other
vehicle.
On your van, use the unpainted
radio antenna bracket as a
remote negative (−) terminal.
{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.
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 donot 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
an unpainted metal part or to a
remote negative (−) terminal if
the vehicle has one. On your
van, use the unpainted radio
antenna bracket as a remote
negative (−) terminal.
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. 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. 7. 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. On your van, use the
unpainted radio antenna bracket
as a remote negative (−)
terminal.
