The LT5 engine in your
ZR-1 has two sets of
intake runners and fuel
injectors. The primary set
can be run alone for
normal engine power, or
both sets can be used for
full engine power.
Full power gives you extra power for highway touring
and off-road sports use and reserve power for passing.
With normal power, you’ll notice less engine and
exhaust noise. To
change the power setting, put your engine power key
into the switch. Turn the key to the setting
you want and
let go. The key will return to the center position.
Your ZR-1 is able to run at full power under the
following conditions:
0 The engine coolant and oil temperatures are greater
than
68°F (20°C) but less than 302°F (150°C).
System voltage is greater than ten volts.
The SERVICE ENGINE SOON light is not on.
You can switch the setting at engine speeds up to
4,000 rpm. When you select the FULL setting, a light
near the switch will come on.
It should go out when you
change back to the NORMAL setting. When you turn
the ignition off, the setting will go back to normal
power.

See your Warranty Book before using your Corvette for
racing
or other competitive driving.
NOTICE:
If you use your Corvette for racing or other
competitive driving, your engine may use more oil than
it would with normal use. Low oil levels
can damage the engine. Be sure to check the oil
level often during racing or other competitive
driving and keep the level at or near the upper
mark on the engine oil dipstick. You may need to
add oil. See “Engine Oil” in the Index.
J
Driving Through Deep Standing
Water
NOTICE:
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine’s air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody of your vehicle.
If you
can’t avoid deep puddles or standing water, drive
through them very slowly.

Downloaded from www.Manualslib.com manuals search engine I NOTICE:
After you’ve used the coolant heater, be sure to store the cord
as it was before to keep it away
from moving engine parts. If you don’t, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the weather, the kind
of oil
you have, and some other things. Instead
of trying to list
everything here, we ask that you contact your Chevrolet
dealer in the area where you’ll be parking your vehicle.
The dealer can give you the best advice for that
particular area.
Automatic Transmission
There are several different positions for your shift lever.
PARK (P): This locks your rear wheels. It’s the best
position
to use when you start your engine because your
vehicle can’t move easily.

Engine Soon Light)
SERVICE
0
SOON
I
A computer monitors
operation
of your fuel,
ignition and emission
control systems. This amber
light should come on when
the ignition is on, but the
engine is not running, as a
check to show you it is
working.
If it does not come
on at all, have it fixed right away. If
it stays on, or it comes on while you are driving, the
computer is indicating that you have
a problem. You
should take your vehicle in for service soon.
NOTICE:
If you keep driving your vehicle with this light on,
after
a while the emission controls won’t work as
well, your fuel economy won’t be as good and your
engine may not
run as smoothly. This could lead to
costly repairs not covered by your warranty.
Engine Oil Pressure Gauge
-1
OIL
PRESS
PSI
The engine oil pressure gauge shows the engine
oil pressure in psi (pounds per square inch) or
kPa (kilopascals) when the engine is running. Oil
pressure should be
20 to 80 psi (140 to 550 Ea). It
may vary with engine speed, outside temperature and oil
viscosity, but readings above the shaded area show the
normal operating range. Readings in the shaded area tell
you that the engine is low on oil, or that you might have
some other oil problem. See “Engine Oil” in the Index.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by your
warranty.
Engine Oil Temperature Gauge
LT1 LT5
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.

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).
System Problems
If SYS flashes on the display near your fuel gauge,
there may be a problem with your Corvette’s electrical
system. If the amber 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.
Gauge Markings
The analog gauges provide a quick visual reference to
the actual measurements of these gauges. However, you
must keep in mind that the gauges aren’t linear. This
means that the middle mark is not a temperature halfway
between the top and bottom temperatures on the gauge.
For your convenience, the following table gives the
exact reading for each mark.

Your fuel gauge shows about how much fuel is in your
tank. The bars light up when the ignition is on or, if the
ignition is off, when
you turn on your parking lamps.
When the display
is down to the last two bars,
RESERVE will appear next to the gauge.
Here
are three concerns some owners have had about the
fuel gauge. All these situations
are normal and do not
indicate that anything is wrong with the fuel gauge.
At the gas station, the fuel pump shuts off before the
gauge reads
FULL (F).

Downloaded from www.Manualslib.com manuals search engine 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 (138 “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 (see “Automatic Transmission Fluid”
in the Index). Also, check the engine coolant
temperature. If it’s too hot, see “Cooling System” in the
Index.
Check Gauges Light
This red 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.
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 oil temperature

This amber light should
come on while you are
starting your engine.
If the
light doesn’t come on, have
it repaired.
If the light
comes on while starting
your engine and stays on,
your engine oil level may be
too low. You may need to
add oil. See “Engine Oil” in
the Index.
Engine Oil Life Monitor
The amber CHANGE OIL
light comes on for a few
seconds when you turn the
ignition
on. It will come on
and stay on when it’s time
to change your oil.
The monitor uses oil temperature and engine revolutions
to decide when the oil is nearly worn out. The light is
only a reminder, though.
You should change your oil at
the intervals recommended in your Maintenance
Schedule, even if the
CHANGE OIL light hasn’t come
on.
