It can be dangerous to drive with the hatch open
because carbon monoxide (CO) gas can come into
your vehicle. You can’t see or smell CO.
It can
cause unconsciousness and even death.
If you must drive with the hatch open or if
electrical wiring or other cable connections must
pass through the seal between the body and the
hatch:
Make sure all windows are shut.
0 Thrn the fan on your heating or cooling
system to its highest speed with the setting
on bi-level or vent. That will force outside
air into your vehicle. See “Comfort
Controls” in the Index.
If you have air outlets on or under the
instrument panel, open them all the
way.
See “Engine Exhaust” in the Index.
NOTICE:
If you put things in the hatchback area, be sure
they won’t break the glass when you close it.
Never slam the hatch down. You could break the
glass or damage the defogger grid.
When you close the hatch, make sure you pull
down from the center, not the sides.
If you pull
the hatch down from the side too often, the
weatherstrip can be damaged.

Automatic transmission
fluid temperature will
be displayed if you press
the GAUGES button on
the trip monitor until
AUTO appears.
The number that appears next to the fuel gauge is the
automatic transmission fluid temperature. If
LO appears,
the temperature is below 32°F (0°C). It’s
normal for the transmission fluid temperature to
vary, depending on the type
of driving you do and
weather conditions. If you drive on long grades on a hot
day, the transmission fluid temperature will be higher
than normal driving on a cold day. If you
drive your
Corvette at high speeds with a lot of stop-and-go or fast
accelerations, your transmission fluid temperature may
also be higher.
If the transmission fluid exceeds
280” F (1 38 “C), the
CHECK GAUGES light will come on and HI AUTO
will be displayed next to the transmission fluid
temperature when you toggle through the GAUGES
button. You should move the shift lever to DRIVE
(D)
and continue driving at a slower, constant speed.
Monitor the transmission fluid temperature and allow it
to cool to 180°F (82°C) to 200°F (93°C). Then, you
should check the transmission fluid level for a low fill or
overfill condition and bring your Corvette in for service
as soon as possible if the oil is too low or overfilled.
(See “Automatic Transmission Fluid” in the Index.)
Also, check the engine coolant temperature. If it’s too
hot, see “Cooling System” in the Index.

warmer air and to the left for cooler air.
Air Control Buttons
OFF: The system is off.
e RECIRCULATE: Provides maximum cooling
or quick cool-down on very hot days. This setting
recirculates most of the air inside your vehicle.
If it is
used for long periods of time, the air may become dry.
This setting directs air through the upper air vents.
It will not work when the outside temperature is
below freezing.

days. This setting cools outside air and directs it through
the instrument panel vents.
The air conditioning compressor operates in NORMAL
A/C, as well as RECIRCULATE, BI-LEVEL and
DEFROST. It only works when the outside temperature
is above freezing. When the air conditioning compressor
is on, you may sometimes notice slight changes in
your vehicle's engine speed and power. This
is normal
because the system is designed to cycle the compressor
on and
off to keep the desired cooling and help
fuel economy.
+,d BI-LEVEL: This setting cools or heats outside air
and directs it through the instrument panel vents and the
floor ducts.
de
do
do /I VENT: Air flows through the instrument panel
vents. The air conditioning compressor does not run in
VENT mode.
wg HEATER: This setting directs most of the air
through the floor ducts and some of the air through the
defroster vents. The air conditioning compressor does
not run in HEATER mode.
DEFROST: This setting directs most of the
air through the windshield defroster and side window
defogger vents and some of the air through the
floor ducts.
Heating
The heater works best if you keep your windows closed
while using it.
Press HEATER and
FAN UP, then slide the temperature
control lever to a comfortable setting.
If your vehicle has an engine coolant heater and you
use it in cold weather,
0°F (- 18 "C) or lower, your
heating system can provide heat more quickly because
the engine coolant is already warmed. See "Engine
Coolant Heater" in the Index.

You may want to use BI-LEVEL on cool, but sunny
days. This setting directs outside air through the
instrument panel vents and the floor ducts.
Press BI-LEVEL and FAN UP, then slide the
temperature control lever to a comfortable setting.
Ventilation
For mild outside temperatures, when little heating or
cooling is needed, you can still direct outside air through
your vehicle.
Press VENT and FAN UP, then slide the temperature
control lever to a comfortable setting.
Defogging and Defrosting
Your vehicle has several settings for clearing your
windows. The air conditioning compressor will run to
help remove moisture from the air.
To defrost the windshield quickly, press DEFROST and
FAN UP, then slide the temperature control lever all the
way
to the right or to the FULL HOT position. To
defrost the side windows quickly, press BI-LEVEL
and FAN UP. Then slide the temperature control lever
all the way
to the right. Direct airflow through the air
conditioning outlets closest to the side windows.
Cooling
The air conditioner works best if you keep your
windows closed. On very hot days, open the windows
just long enough for the hot air to escape.
Press RECIRCULATE and FAN UP. Then slide the
temperature control lever to a comfortable setting.
Direct airflow through the air conditioning outlets
closest to the side windows.
After cool-down, adjust the air control buttons to
another setting. The compressor works in all settings
except VENT and HEATER and at all temperatures
above freezing.
When the air conditioning compressor is on, you may
notice slight changes in your vehicle’s engine speed and
power. This is normal because the system is designed to
cycle the compressor
on and off to keep the desired
temperature and help fuel economy.

planning to visit there, here are some tips that can make
your trips safer and more enjoyable.

0 Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transmission. These parts can work hard on
mountain roads.
Know how to
go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Shift
to a lower gear when you go
down a steep or long hill.
I
If you don’t shift down, your brakes could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a hill.
You could crash. Shift down to let your engine
assist your brakes on a steep downhill slope.
’ A CAUTION:
I
Coasting downhill in NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do all the work of slowing down. They could get
so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a
hill.
You could crash. Always have your engine running
and your vehicle
in gear when you go downhill.
Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transmission, and you can climb the
hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don’t swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.

special problems. Examples are long grades, passing or
no-passing zones, a falling rocks area or windmg
roads. Be
alert to these and take appropriate action.

Downloaded from www.Manualslib.com manuals search engine When it is cool, remove the coolant recovery tank cap
and look at the dipstick.
The coolant level should be at or above
COLD. 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.
.h CAUTION:
*
8’
Heater and radiator hoses, and other engine
parts, can be very
hot. Don’t touch them. If you
do, you can be bul‘ned.
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:
I
Engine damage from running your engine
without coolant isn’t covered by your warranty.
I
If there seems to be no leak, with the engine on, 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.
