open hood CHEVROLET CORVETTE 2001 5.G Owners Manual

2-27 To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is attached to the generator
bracket assembly, between the generator and the
windshield washer fluid tank.With the headlamps
closed, route the cord in the opening between the
headlamp door and the fender panel on the driver's
side of the vehicle. Do not pinch the cord when
closing the hood.
3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't reach, use a
heavy
-duty three-prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug and 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 outside temperature, the kind
of oil you have, and some other things. Instead of trying to
list everything here, we ask that you contact your dealer in
the area where you'll be parking your vehicle. The dealer
can give you the best advice for that particular area.

You can open the doors manually using the knob next to
the headlamp assembly. Turn the knob counterclockwise
until the doors are open. Turn the knob clockwise to
close the doors manually.
The headlamp doors should be open when driving in
icy or snowy conditions to prevent the doors from
freezing closed and when washing the vehicle to help
clean the headlamps.
NOTICE:
In order to avoid possible contact of the hood to
the headlamp doors, either take care in raising
the hood with the headlamps up, or turn off the
headlamps prior to opening the hood.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or high
to low, push the turn signal lever all the way forward.
When the high beams
are on, this light on the
instrument panel cluster
also will be on. To change
the headlamps from high to
low, pull the lever rearward.
Lamps on Reminder
If you turn the ignition off and leave the headlamps or
parking lamps on and open a door, you will hear a chime
reminding you to turn off the lamps.
Flash-to-Pass Feature
To use the flash-to-pass feature, momentarily pull the
turn signal lever toward you. The high
-beam indicator
will flash to indicate to the other driver that you intend
to pass. If the low
-beam headlamps are off and you have
the optional fog lamps on, the fog lamps will flash.

2-54
Reading Lamps
Your inside rearview mirror includes two reading lamps.
The lamps will go on when a door is opened. When the
doors are closed, each lamp can be turned on individually
by pressing the switch (each lamp has its own switch).
There is also an interior console flood lamp located
underneath the rearview mirror which comes on with the
headlamps or parking lamps.
Inadvertent Load Control
Your vehicle has a feature to help prevent you from
draining the battery in case the underhood lamp, vanity
mirror lamps, cargo lamps, reading lamps, console or
glove box lamps are accidentally left on. If you leave any
of these lamps on, they will automatically time out after
about 15 minutes. To reset it, all of the above lamps must
be turned off or the ignition key must be in ON.
Mirrors
Inside Day/Night Rearview Mirror
An inside rearview mirror is attached above the
windshield. The mirror pivots so that you can adjust it.
You can adjust the mirror for day or night driving. Pull
the tab for night driving to reduce glare. Push the tab
forward for daytime driving.

2. Get the vehicles close enough so that the jumper
cables can reach, but be sure the vehicles aren't
touching each other. If they are, it could cause a
ground connection you don't want. You wouldn't be
able to start your vehicle, and the bad grounding
could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory plug. Turn off all lamps that
aren't needed as well as radios. This will avoid
sparks and help save both batteries. In addition, it
could save your radio.
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (
-) terminals on each.
CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.

5-9 If Steam Is Coming From Your Engine
CAUTION:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool. See ªOverheated Engine
Protection Operating Modeº in the Index.

5-10
NOTICE:
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. See ªOverheated
Engine Protection Operating Modeº in the Index.
If No Steam Is Coming From Your Engine
If you get an engine 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:

Climb a long hill on a hot day.

Stop after high
-speed driving.

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. If your air conditioner is on, turn it off.
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 (
) or
THIRD (3) for automatic transmissions.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 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, idle the engine for
three minutes while you're parked. If you still have the
warning, turn off the engine and get everyone out of the
vehicle until it cools down. Also, see ªOverheated
Engine Protection Operating Modeº listed previously in
this section.
You may decide not to lift the hood but to get service
help right away.

6-4
Be sure the posted octane for premium is at least 91 (at
least 87 for regular). If the octane is less than 87, you
may get a heavy knocking noise when you drive. If it's
bad enough, it can damage your engine.
If you're using fuel rated at the recommended octane or
higher and you hear heavy knocking, your engine needs
service. But don't worry if you hear a little pinging
noise when you're accelerating or driving up a hill.
That's normal, and you don't have to buy a higher
octane fuel to get rid of pinging. It's the heavy, constant
knock that means you have a problem.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to operate on fuels that meet
California specifications. If such fuels are not available
in states adopting California emissions standards, your
vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator
lamp on your instrument panel may turn on and/or your
vehicle may fail a smog
-check test. See ªMalfunction
Indicator Lampº in the Index. If this occurs, return to
your authorized Chevrolet dealer for diagnosis to
determine the cause of failure. In the event it is
determined that the cause of the condition is the type of
fuels used, repairs may not be covered by your warranty.Some gasolines that are not reformulated for low
emissions may contain an octane
-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask your service station operator whether or not
the fuel contains MMT. General Motors does not
recommend the use of such gasolines. If fuels containing
MMT are used, spark plug life may be reduced and your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel may turn on. If this occurs, return to your
authorized Chevrolet dealer for service.
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add
anything to the fuel. In addition, gasolines containing
oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
contribute to clean air. General Motors recommends that
you use these gasolines, particularly if they comply with
the specifications described earlier.

Filling a Portable Fuel Container
CAUTION:
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from the
container can ignite the gasoline vapor. You can
be badly burned and your vehicle damaged if this
occurs. To help avoid injury to you and others:

Dispense gasoline only into
approved containers.

Do not fill a container while it is inside a
vehicle, in a vehicle's trunk, pickup bed or
on any surface other than the ground.

Bring the fill nozzle in contact with the
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.

Don't smoke while pumping gasoline.
Checking Things Under the Hood
CAUTION:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
CAUTION:
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop or spill
things that will burn onto a hot engine.

6-10 Hood Release
NOTICE:
In order to avoid possible contact of the hood to
the headlamp doors, either take care in raising
the hood with the headlamps up, or turn off the
headlamps prior to opening the hood.
To open the hood, first
pull the handle located
inside the vehicle below
the instrument panel on
the driver's side.
Then go to the side of the vehicle and pull up on the rear
edge of the hood, near the windshield.
Before closing the hood, be sure all the filler caps are
on properly. Then, just pull the hood down and close
it firmly.
