lights CHEVROLET CORVETTE 1994 4.G Owner's Manual

Downloaded from www.Manualslib.com manuals search engine Run your engine only as long as you
must. This saves fuel. When you run the
engine, make it go a little faster than just
idle. That is, push the accelerator slightly.
This uses less fuel for the heat that you
get and it keeps the battery charged. You
will need a well-charged battery to restart
the vehicle, and possibly for signaling
later on with your headlights. Let the
heater run for awhile.
Then, shut the engine
off and close the
window almost all the way to preserve the
heat. Start the engine again and repeat this
only when you feel really uncomfortable
from the cold. But do it as little as
possible. Preserve the fuel as long as you
can.
To help keep warm, you can get out
of the vehicle and do some fairly vigorous
exercises every half hour or
so until help
comes.
Towing a Trailer
Your Corvette is neither designed nor
intended to tow a trailer.

If your battery has run down, you may
want to use another vehicle and some
jumper cables to start your Corvette.
But please follow the steps below to
do it safely.
NOTICE:
Ignoring these steps could result
in costly damage to your vehicle
that wouldn’t be covered by your
warranty.
Trying to start your Corvette by
pushing or pulling it could damage
your vehicle,
even if you have a
manual transmission. And if you
have an automatic transmission, it
won’t start that way.
Ib Jump Start Your Corvette:
1. Check the other vehicle. It must have
a 12-volt battery with a- negative
ground system.
NOTICE:
If the other system isn’t a 12-volt
system with a negative ground, both
vehicles can be damaged.
2. Get the vehicles close enough so 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
Corvette, and the bad grounding could
damage the electrical systems.
3. Turn off the ignition on both vehicles.
Turn
off all lights that aren’t needed,
and radios. This will avoid sparks and
help save both batteries. And it could
save your radio!
I NOTICE:
I
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.

Remove the nut on the outboard side
of the unit. Then loosen the front and
inboard nuts. For the LT5 engine, loosen
the two inboard nuts. Move the ECM unit
to either side.
Fluid should be added if the fluid level
is at or below the “ADD” mark on the
reservoir. There are additional instructions
on the reservoir cap.
When returning the ECM to its proper
position, make sure the bolts are aligned
with the slots in the bracket. Then gently
push down on the unit. When replacing
the unit, be careful not to over-tighten the
nuts -just tighten them until they are
snug.

When to Check Lubricant
Refer to the Maintenance Schedule
to determine how often to check the
lubricant. See “Periodic Maintenance
Inspections” in the Index.
How to Check Lubricant
If the level is below the bottom of the
filler plug hole, you’ll need to add some
lubricant. Add enough lubricant to raise
the level to the bottom of the filler plug
hole.
What to Use:
To add lubricant when the level is low, use
Axle Lubricant (GM Part
No. 12345977)
or
SAE 8OW-90 GL-5 gear lubricant.
To completely refill after draining,
add 4 ounces (1 18 ml) of Limited-Slip
Differential Lubricant Additive (GM Part
No. 1052358). Then fill to the bottom of
the filler plug hole with Axle Lubricant
(GM Part
No. 12345977) or SAE 8OW-90
GL-5 gear lubricant.
Engine Coolant
The following explains your cooling
system and how to add coolant when
it
is low. If you have a problem with
engine overheating or
if you need to add
coolant to your high fill reservoir, see
“Engine Overheating” in the Index.
The proper coolant for your Corvette will:

0
0
0
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262°F
(128°C).
Protect against rust and corrosion.
Help keep the proper engine
temperature.
Let the warning lights work as they
should.

Downloaded from www.Manualslib.com manuals search engine Battery
Every new Corvette has a Delco
Freedom@ battery.
You never have to add
water to one of these. When it’s time for
a new battery, we recommend a Delco
Freedom@ battery. Get one that has the catalog number shown on the original
battery’s label. For battery replacement,
see your dealer or the Corvette Service
Manual.
To purchase a service manual,
see “Service Publications” in the Index.
Vehicle Storage
If you’re not going to drive your vehicle
for
25 days or more, take off the black,
negative
(-) cable from the battery. This
will help keep your battery from running
down. Contact your
dealer to learn how to
prepare your vehicle for longer storage
periods.
Bulb Replacement
For the proper type of replacement bulb,
see “Replacement Bulbs” in the Index.
Halogen Bulbs
Headlight
1. Open the hood.
2. The headlights need to be halfway
open. Turn the headlight switch on,
then quickly back to the parking lights
setting.
You may have to do this a few
times to get the half-open position.
You can also open the headlights
manually. See “Concealed
Headlights”
in the Index.

Downloaded from www.Manualslib.com manuals search engine Fuses and Circuit
Breakers
The wiring circuits in your vehicle are
protected from short circuits by a
combination of maxi-fuses, mini-fuses
and circuit breakers. This greatly reduces
the chance of fires caused by electrical
problems.
There are three fuse centers on your
vehicle. One
is in the right side of your
instrument panel. Turn the knob and pull
the door to access the fuses. The other
two fuse blocks are in the
engine compartment. One is part of the
Forward Lamp wiring harness
(A), and
the other is part of the ECM-Engine
wiring harness
(B).
Look at the silver-colored band inside
the fuse. If the band is broken or melted,
replace the fuse. Be sure you replace a
bad fuse with a new one of the correct
size.
If you ever have a problem on the road
and don’t have a spare fuse, you can
borrow one of the correct value. Just pick
some feature of your vehicle that you can
get along without
- like the radio or
cigarette lighter
- and use its fuse, if it
is the size you need. Replace it as soon
as you can.
Headlights
The headlight wiring is protected by a
circuit breaker
in the switch. An electrical
overload will cause the lights to go on and
off, or in some cases to remain
off. If this
happens, have your headlight wiring
checked right away.
Windshield Wipers
The windshield wiper motor is protected
by a circuit breaker and a fuse. If the
motor overheats due to heavy snow, etc.,
the wiper will stop until the motor cools.
If the overload is caused by some
electrical problem and not snow, etc.,
be sure to get
it fixed.
Power Windows and Other Power
Options
Circuit breakers protect the power
windows and other power accessories.
When the current load is too heavy,
the circuit breaker opens and closes,
protecting the circuit until the problem
is fixed or goes away.
