CAUTION: (Continued)
Be sure the batteries have enough water. You don’t need to add
water to the Delco Freedoms bittery 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
i you. If you accidentally get it in your eyes or on your skin, flush
~ the place with water and get medical help immediately.

they do, you could get a shock. The vehicles could be damaged, too.
Before you connect the cables, here are some things
you should know.
Positive

may have a
leak in the radiator hoses, heater hoses, radiator, water pump
or somewhere else
in the cooling system.
I
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 electric engine fans are
running.
If the engine is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

How to Add Coolant to the Coolant Surge Tank
If you haven’t found a problem yet, but the coolant level isn’t at or above
“FULL COLD,” add a 50/50 mixture of clean water (preferably distilled)
and a proper antifreeze at
the coolant recovery tank. (See “Engine
Coolant”
in the Index for more information about the proper coolant
mix.)
A CAUTION
Adding only plain water to your cooling system can De
dangerous. Plain water, or some other liquid like alcohol, can
boil before the proper coolant mix will.
Your vehicle’s coolant
warning system is set
for the proper coolant mix. With plain
water
or the wrong mix, your engine could get too hot but you
wouldn’t get the overheat warning. Your engine could catch fire
and you or others could be burned. Use a
50/50 mix of clean
water and
a proper antifreeze.

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.
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
repaired or replaced where you want. Of course, it’s best to replace your
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.

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

" 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).
