I A CAUTION:
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 battery has enough water. You don’t need to add
water to the Delco Freedom@ battery installed in every new
GM
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 don’t, explosive gas could be present.
Battery fluid contains acid that can burn you. Don’t 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.

5. Check that the jumper cables don’t 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 (+) and negative (-) will go to
negative
(-) or a metal engine part. Don’t connect (+) to (-) or you’ll
get a short that would damage the battery and maybe other parts, too.

may have a leak in the radiator hoses, heater hoses, radiator, water pump
or somewhere else
in the cooling system.
A CAUTION:
Heater and radiator hoses, and other engine parts, can be very
hot. Don’t touch them.
If you do, you can be burned.
Don’t run the engine if there
is a leak. If you run the engine, it
could lose all coolant. That could cause an engine fire, and you
could be burned. Get any leak fixed before you drive the vehicle.

If there seems to be no leak, check to see if the fan or if equipped electric --
engine fans are running. If the engine is overheating, both fans should be
running.
If they aren’t, your vehicle needs service.

COMPACT SPARE TIRE
Although the compact spare was fully inflated when your vehicle was
new, it can lose air after a time. Check the inflation pressure regularly. It
should be
60 psi (420 kPa). The compact spare is made to go up to 3,000 -
miles (5000 km), so you can finish your trip and have your full-size tire i* u
repaired or replaced where you want. Of course, it’s best to replace your I
spare with a full-size tire as soon as you can. Your spare will last longer
and be in good shape in case you need it again.
Your anti-lock brake system warning light may come on when
you are
driving with a compact spare. See “Anti-Lock Brake System Warning
Light” in the Index.
Don’t use your compact spare on some other vehicle.

detergents and oxygenates, and if they have been reformulated to reduce
vehicle emissions.
FUELS IN FOREIGN COUNTMES
If you plan on driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can
corrode, and your engine
oil can deteriorate quickly. Your vehicle’s
oxygen sensor
will be damaged. All of that means costly repairs that
wouldn’t be covered by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.
You can also write us at the following address for advice. Just tell
us
where you’re going and give your Vehicle Identification Number (VIN).
