Downloaded from www.Manualslib.com manuals search engine Engine Power Switch (ZR-1)
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.

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.

Downloaded from www.Manualslib.com manuals search engine Be sure to reset the monitor when your oil is changed,
even if the CHANGE OIL light didn’t come on. If you
don’t reset the monitor, it won’t work correctly. Follow
these steps:
1. Turn the key to RUN, but don’t start the engine.
2. Press ENG MET on the Trip Monitor. Then, within
five seconds, press it again.
3. Witbin five seconds, press and hold GAUGES on the
Trip’Monitor. The CHANGE OIL light should flash.
4. Hold the GAUGES button until the CHANGE OIL
light stops flashing and goes out. This should take
about ten seconds.
When the light goes out, the monitor is reset. If the
monitor doesn’t reset, turn the ignition
off, then try
again.
Service Ride Control Light

CONTROL
If your vehicle is equipped
with Selective Ride Control,
this amber light should
come on for
a few seconds
when you start your vehicle.
If the light stays on or comes on while you’re driving,
there may be
a problem with your Selective Ride
Control system. You can still drive, but you should see
your dealer soon.
The Selective Ride Control system is designed to sense
vehicle speed in the first minute after the vehicle is
started. If the vehicle is not moved in that first minute,
the system records a fault. The SERVICE RIDE
CONTROL light comes on after three faults are
recorded. If the light comes on for this reason, move
your Corvette and the light should
go out.

only those oils that are identified as meeting GM
Standard
4718M and have the “Starburst” symbol on the
front of the oil container.
Your Corvette engine is filled at the factory with a
Mobil
1 @ synthetic oil, which meets all requirements for
your vehicle.
Substitute Oil (LTl Only): When adding oil to
maintain engine oil level, oil meeting GM Standard
GM47
18M may not be available. You can add substitute
oil designated
SAE 5W-30 with the “Starburst” symbol
or API Service SH at all temperatures. If temperatures
are above
0” F (- 18 O C), you may substitute SAE
1OW-30 with the “Starburst” symbol or API Service
SH
oil. This oil should not be used for an oil change.
Substitute Oil (LT5 Only): When adding oil to
maintain engine oil level,
if an oil meeting GM Standard
GM47
18M is not available, you can use oil designated
SAE 1OW-30 with the “Starburst” symbol or API
~ Service SH at all temperatures. This oil should not be
used for
an oil change.
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.

Downloaded from www.Manualslib.com manuals search engine What to Do with Used Oil
Did you know that used engine oil contains certain
elements that
may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or throw away
clothing or rags containing used engine oil. (See the
manufacturer’s warnings about the use and disposal of
oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose
of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it
by taking it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.
Air Cleaner
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See “Scheduled Maintenance Services” in the Index.

Then install the longer knobs into the outer holes.
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed. Refer to the
Maintenance Schedule to determine when to change
your fluid. See “Scheduled Maintenance Services” in the
Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Chevrolet dealer
Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading on the
dipstick.

I NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your
transmission fluid.

Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance or the
removal
of important components can significantly
affect the quality
of the air we breathe. Improper fluid
levels
or even the wrong tire inflation can increase the
level of emissions from your vehicle.
To help protect our
environment, and to help keep your vehicle in good
condition, please maintain your vehicle properly.
Have you purchased the GM Protection Plan ? The Plan

(166

Footnotes
3- The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to the
completion of vehicle useful life. We, however, urge that
all recommended maintenance services be performed at
the indicated intervals and the maintenance be recorded.
I
* Your vehicle has an Engine Oil Life Monitor. This
monitor will
show you when to change the oil -- usually
between
3,000 miles (5 000 km) and 7,500 miles
(12
500 km) since your last oil change. Under severe
conditions the indicator may come on before
3,000 miles
(5 000 km). Never drive your vehicle more than
7,500 miles (12 500 km) or 12 months without an oil
change.
The system won’t detect dust in the oil.
So if you
drive in a dusty area be sure to change your oil every
3,000 miles (5 000 km) or sooner if the CHANGE OIL
light comes on. Remember to reset the Oil Life Monitor
when the oil has been changed.
For more information,
see “Engine Oil Life Monitor” in the Index.
