Ventilation Tips
Keep the hood and front air inlet free of ice, snow or any
other obstruction (such as leaves). The heater and
defroster will work far better, reducing the chance of
fogging the inside
of your windows.
When you enter a vehicle in cold weather, move the fan
control lever toward the fan symbol for a few moments
before driving off. This helps clear the intake ducts of
snow and moisture, and reduces the chance
of fogging
the inside of your windows.
Keep the air path under the front seats clear of objects.
This helps air to circulate throughout your vehicle.
Defogging and Defrosting
Slide the air intake lever to CIRCULATE and the
airflow lever to DEFROST to direct air to the
windshield vents.
Then slide the temperature control
lever toward the right and the fan lever toward the fan
symbol. When the windshield
is clear, turn down the
fan speed.
Rear Window Defogger
The rear window defogger uses a warming grid
to
remove fog from the
rear window.
Press the switch to turn
on the defogger. An indicator
light will come on below the switch to remind you that
the defogger is on. Press the switch again to turn the
defogger
off. The rear window defogger will also turn
off
if you turn the ignition switch to ACC or LOCK, but
will turn
back on when the ignition is turned back on.
Do not attach anything like a temporary vehicle license
or
a decal across the defogger grid on the rear window.

Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on with your headlamps. Let the heater run for awhile.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But
do it as little as possible. Preserve the
fuel as long as you can.
To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.

If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute
or so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving --AUTOMATIC OVERDRIVE
0 or
DRIVE (D) for automatic transmissions.
Ii‘ you no longer have the overheat warning, you
can drive.
Just to be safe, drive slower for about
10 minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see
if
the warning stops. But then, if you still have the
warning,
turn off the engine and get everyone out of the
vehicle
until it cools down.
You may decide not to lift the hood but to get service
help right away.

The coolant level should be at or above FULL.
If it isn’t, you 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.
I NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine fan is running.
If the engine is
overheating, the fan should be running.
If it isn’t, your
vehicle needs service.

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at or above the
FULL mark, add a 50/50 mixture
of clean water (preferably distilled) and a proper coolant
at the coolant recovery tank. (See “Engine Coolant’’
in the Index for more information about the proper
coolant
mix.)
Adding only plain water to your cooling system
can be 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 coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mix.

What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half coolant that meets
GM
Specification 1825-M, which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825-M with a complete coolant flush
and refill. If you use this mixture, you don’t need to add
anything else.
Adding only plain water to your cooling system

I
NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by your
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
I NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
