Your vehicle has several settings for clearing your
windows. The air conditioner compressor will run to
help remove moisture from the air.
To defrost the windshield quickly, press the arrows on
the
TEMP SET switch to set a comfortable temperature.
Press DEFROST and the fan will go to high speed. After
the windows are clear, you can lower the speed using the
downward arrow or
AUTO FAN.
With the automatic system, to warm passengers while
keeping the windshield clear? press the arrows on the
TEMP SET switch to set a comfortable temperature. Press
HEATER and DEFROST at the same time and, if you
don’t like the automatic setting, press the
arrows on the fan
speed switch.
To defrost the side windows quickly, press the arrows on
the
TEMP SET switch to set a comfortable temperature.
Then press DEFROST and,
if you don’t like the automatic
setting, press the arrows on the fan speed switch.
System Problems
If the light above an air control button flashes when you
turn on the ignition, your system may have an electrical
problem. The flashing will continue for one minute, then
stop.
The flashing light could also mean the refrigerant level
is too low in your system. The light will continue to
flash, even if refrigerant is added, until the system is
reset. Have your system checked and serviced if needed.
To reset your system:
1. Turn your ignition key to OFF or LOCK.
2. Remove the courtesy lamps and radio fuses from the
main fuse panel and wait one minute. See “Fuses and
Circuit Breakers” in the Index.
3. Put the fuses back in and start your vehicle.
The light shouldn’t come on and your system should be
working properly. If you still have a problem, see your
dealer.

Your Corvette's flow-through ventilation system
supplies outside air into the vehicle when it is moving.
Outside air will also enter the vehicle when the heater or
the air conditioning fan is running.
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, adjust the
fan to the highest speed 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.
Audio Systems
Your Delco@ audio system has been designed to operate
easily and give years
of listening pleasure. But you will
get the most enjoyment out of it
if you acquaint yourself
with
it first. Find out what your Delco system can do
and how to operate all its controls, to be sure you're
getting the most out of the advanced engineering that
went into it.
Setting the Clock
Press SET. Within five seconds, press and hold TUNE
until the correct hour appears. Press and hold TUNE
A
until the correct minute appears.
Noise Reduction
Your audio system has automatic Dolby@ B Noise
Reduction.

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 headlights. 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.

I
If’ your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would
not be
covered by your warranty.
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.
Stop after high speed driving.
0 Idle for long periods in traffic.
If you get the overheat warning with no sign
of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
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 (a)
or DRIVE (D) for automatic transmissions.
If you
no longer have the overheat warning, you can drive.
Just to be safe, drive slower for about ten 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.

isn’t, you may have a leak in the radiator hoses, heater
hoses, radiator, water pump or somewhere else in the
cooling system.
NOTICE:
Engine damage from running your engine

If there seems to be no leak, with the engine on check to

If the engine

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the ,coo,lant level
isn’t at or above the COLD mark, add
a 50MI mixture
of clean water (preferably distilled) and a proper
antifreeze at the coolant recovery tank. (%e “Engine
Coolant” in the Index for more information about the
proper coolant mix.)

engine, radiator, heater core and other parts. Use
the recommended coolant.
When the coolant in the coolant recovery tank is at or

If the overheat warning continues, there's one more
thing you can try.
You can add the proper coolant mix
directly to the coolant high fill reservoir, but be sure the
cooling system
is cool before you do it.

your vehicle.
Substitute Oil (LTl Only): When adding oil to

Engine Oil Additives
Don’t add anything to your oil. Your Chevrolet dealer is
ready to advise if you think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
0 Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop and
go traffic).
Most trips are through dusty areas.
If any one of these is true for your vehicle, you need to
change your oil and filter every 3,000 miles
(5 000 km)
or 3 months -- whichever comes first. (See “Engine Oil
Life Monitor” in the Index.)
If none of them is true, change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
comes first. (See “Engine Oil Life Monitor” in the
Index.)
Engine Coolant Heater
An engine coolant heater can be a big help if you have
to
park outside in very cold weather, 0” F (- 1 8 O C) or
colder. If your vehicle has this feature, see “Engine
Coolant Heater” in the Index.

If you use an improper coolant mix, your engine
could overheat and be badly damaged. The

Too much water in the mix can freeze

Adding Coolant
To Check Coolant
When your engine is cold, check the dipstick on the cap
of the coolant recovery tank. The coolant level should
be at COLD, or a little higher. When your engine is
warm, the level on the dipstick should be up to the HOT,
or a little higher. Your
Corvette also has
a high fill reservoir located at the
right rear of the engine compartment.
If the recovery tank
is very low or empty, also add
coolant to the
high fill reservoir. To add coolant at the
high fill reservoir, see “Engine Overheating” in the
Index.
