OIL TEMP OF
This gauge shows your
engine oil temperature. Oil
temperature may vary with
the type
of driving you do
and weather conditions.
If your gauge pointer moves close to or into the shaded
area and stays there, your oil temperature is too high.
Check the engine coolant temperature and engine oil
level.
If your engine is too hot, see “Engine
Overheating” in the Index. Your vehicle may need
service; see your dealer.
I,
For numeric gauge
measurements, press the GAUGES button on the trip
monitor until
OIL appears.
The number that appears next to the fuel gauge is the oil
temperature.
If LO appears, the temperature is below
32°F (OOC).

SECURITY
This light comes on to
remind you to
arm your
theft-deterrent system. If it
comes on and stays on when
your ignition is on, there
may be a problem with your
theft-deterrent system.
CHECK
GAUGES
This light will come on
briefly when you are
starting the engine.
If the
light comes on and stays on
while you are driving, check
your gauges to see if they
are in the warning areas.

System” in the Index.
System Problems Light
If SYS flashes on the display near your fuel gauge, there
may be a problem with your Corvette’s electrical
system. If the
SECURITY light flashes at the same time,
there is
a problem with your theft-deterrent system.
Have your vehicle checked by your dealer
if SYS keeps
appearing. This
light can come on for:
0 High Engine Oil Temperature or Low oil Pressure
High Coolant Temperature
High or Low Battery Voltage
0 Low Fuel Level
0 High Automatic Transmission Fluid Temperature

Downloaded from www.Manualslib.com manuals search engine Automatic Transmission Fluid Temperature Reading
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.

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.

and directs it through the instrument panel vents and the
floor ducts.

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.

The system will adjust to maintain the'temperature you
set. It will select the best fan speed and aifflow setting to
keep you comfortable with the least amount of noise.
Press the arrows on the TEMP SET switch to set a
comfortable temperature. Then press AUTO and the fan
speed will adjust automatically unless you press the
arrows on the AUTO switch.
Manual Heating
The heater works best if you keep your windows closed
while using it.
Press the arrows on the TEMP SET switch to set a

you don't like the automatic setting, press the arrows on
the fan speed switch. In AUTO FAN on cold days, the
fan will stay
off until the coolant warms up enough to
heat your vehicle.
If your vehicle has an engine coolant heater and you use
it in cold weather,

Manual Bi-Level
BI-LEVEL can heat or cool outside air and direct it in
two directions.
Press the arrows on the TEMP SET switch to set a
comfortable temperature. Press BI-LEVEL and, if you
don't like the automatic setting, press the arrows on the
fan speed switch.
Manual Ventilation
For mild outside temperatures, when little heating or
cooling
is needed, you can still direct outside air through
your vehicle.
Press the arrows on the TEMP SET switch to set a
comfortable temperature. For ventilation, the system
can't cool the vehicle below the outside temperature.
Press VENT and, if you don't like the automatic setting,
press the arrows on the fan speed switch.

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:

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.

Downloaded from www.Manualslib.com manuals search engine 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 COLD mark, add a 50/50 mixture
of
clean water (preferably distilled) and DEX-COOL“
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant” in the Index
for more information.)
-
A CAUTION:
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
DEX-COOL TM antifreeze.
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.

four minutes. By
this time, the coolant level inside the
coolant high fill reservoir will be lower. Add more of
the proper mix through the filler neck until the level
reaches the base of the filler neck.

9. Shut the engine off and replace the pressure cap. Be
sure the arrows on the cap line up like this.
10. Then fill the coolant recovery tank to the proper level.
For a complete drain, flush and refill, see your Chevrolet
dealer or
a Chevrolet Corvette Service Manual. To
purchase a service manual, see “Service and Owner
Publications’’ in
