{Warning
Using the wrong replacement wheels,
wheel bolts, or wheel nuts can be
dangerous. It could affect the braking and
handling of the vehicle. Tires can lose air,
and cause loss of control, causing a crash.
Always use the correct wheel, wheel
bolts, and wheel nuts for replacement.
Caution
The wrong wheel can also cause
problems with bearing life, brake cooling,
speedometer or odometer calibration,
headlamp aim, bumper height, vehicle
ground clearance, and tire or tire chain
clearance to the body and chassis.
Used Replacement Wheels
{Warning
Replacing a wheel with a used one is
dangerous. How it has been used or how
far it has been driven may be unknown.
It could fail suddenly and cause a crash.
When replacing wheels, use a new GM
original equipment wheel.
Tire Chains
{Warning
Tire chains or other traction devices used
on a vehicle without the proper amount
of clearance can cause damage to the
brakes, suspension, or other vehicle parts.
Use tire chains or traction devices only if
the equipment manufacturer recommends
them for the vehicle tire size combination
and road conditions. Follow the
equipment manfacturer’s instructions. The
area damaged by the tire chains could
cause you to lose control of the vehicle
and you or others may be injured in a
crash. To help avoid damage to the
vehicle, drive slowly, readjust, or remove
the device if it is contacting the vehicle.
Do not spin the vehicle's tires.
Caution
Use tire chains only where legal and only
when necessary. Use chains that are the
proper size for the tires. Install them on
the tires of the rear axle. Do not use
chains on the tires of the front axle.
(Continued)
Caution (Continued)
Tighten them as tightly as possible with
the ends securely fastened. Drive slowly
and follow the chain manufacturer's
instructions. If the chains contact the
vehicle, stop and retighten them. If the
contact continues, slow down until it
stops. Driving too fast or spinning the
wheels with chains on will damage the
vehicle.
For Cutaway models with LT245/75R16 or
LT225/75R16 size single or dual rear tires, use
Low Profile Z-Chain or SAE Class S cables.
For Cargo or Passenger models with
LT225/75R16 or LT245/75R16 size tires, use
Low Profile Z-Chain cables. SAE Class S chains
are not recommended.
If the vehicle has dual rear tires, do not use
individual tire chains. Use tire chains that fit
across both dual tires.
If a Tire Goes Flat
It is unusual for a tire to blow out while
driving, especially if the tires are maintained
properly. See Tires0204. If air goes out of
a tire, it is much more likely to leak out

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.
8. Connect the other end of thenegative (−) cable to the negative (−)
terminal location on the vehicle with the
dead battery. On your van, use the
unpainted radio antenna bracket as a
remote negative (−) terminal.
Caution
The vehicle uses the unpainted radio
antenna bracket as a remote negative (-)
terminal. Move the antenna coaxial cable
out of the way before clamping the
negative jumper cable to the fixed
antenna bracket. Avoid touching the
negative cable clamp to the air
conditioning line. Failure to do either of

these could damage the vehicle. The
repairs would not be covered by the
vehicle warranty.
9. Now start the vehicle with the good battery and run the engine for a while.
10. 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.
After starting the disabled vehicle and
removing the jumper cables, allow it to idle
for several minutes.

.Use only approved cleaning solutions for
aluminum, chrome, or stainless steel.
Some cleaners are highly acidic or contain
alkaline substances and can damage the
moldings.
.Always dilute a concentrated cleaner
according to the manufacturer’s
instructions.
.Do not use cleaners that are not intended
for automotive use.
.Use a nonabrasive wax on the vehicle
after washing to protect and extend the
molding finish.
Cleaning Exterior Lamps/Lenses,
Emblems, Decals, and Stripes
Use only lukewarm or cold water, a soft
cloth, and a car washing soap to clean
exterior lamps, lenses, emblems, decals, and
stripes. Follow instructions under "Washing
the Vehicle" previously in this section.
Lamp covers are made of plastic, and some
have a UV protective coating. Do not clean
or wipe them while they are dry.
Do not use any of the following on lamp
covers:
.Abrasive or caustic agents.
.Washer fluids and other cleaning agents
in higher concentrations than suggested
by the manufacturer.
.Solvents, alcohols, fuels, or other harsh
cleaners.

.Aftermarket appearance caps or covers
while the lamps are illuminated, due to
excessive heat generated.
Caution
Failure to clean lamps properly can cause
damage to the lamp cover that would
not be covered by the vehicle warranty.
Caution
Using wax on low gloss black finish
stripes can increase the gloss level and
create a non-uniform finish. Clean low
gloss stripes with soap and water only.
Air Intakes
Clear debris from the air intakes, between
the hood and windshield when washing the
vehicle.
Windshield and Wiper Blades
Clean the outside of the windshield with
glass cleaner.
Clean rubber blades using a lint-free cloth or
paper towel soaked with windshield washer
fluid or a mild detergent. Wash the
windshield thoroughly when cleaning the
blades. Bugs, road grime, sap, and a buildup
of vehicle wash/wax treatments may cause
wiper streaking.
