NOTICE:
Spinning your wheels can destroy
parts of your vehicle as well as the
tires. If you spin the wheels too fast
while shifting your transmission
back and forth, you can destroy your
transmission.

Rocking your vehicle to get it out:
First, turn your steering wheel left and
ight. That will clear the area around your
front wheels. You should
turn your ASR
system
off. (See “ASR System” in the
[ndex.) Then shift back and forth between
“R’ (Reverse) and a forward gear (or with
9 manual transmission, between First or
Second gear and Reverse), spinning the
wheels as little as possible. Release the
accelerator pedal while you shift, and
press lightly on the accelerator pedal
when the transmission is in gear. If that
doesn’t get you out after a few tries, you
may need to be towed out.
If you do need
to be towed out, see “Towing Your
Vehicle” in the Index.

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:

Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262°F

temperature.

should.

Downloaded from www.Manualslib.com manuals search engine Brake Master Cylinder
Your brake master cylinder is here. It is
filled with DOT-3 brake fluid.
There are only two reasons why the brake
fluid level in your master cylinder might
go down. The first is that the brake fluid
goes down to an acceptable level during
normal brake lining wear. When new
linings are put in, the fluid level goes
back up. The other reason is that fluid is
leaking out of the brake system.
If it is,
you should have your brake system fixed,
since a leak means that sooner or later
your brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your
brake fluid. Adding brake fluid won’t
correct a leak. If you add fluid when your
linings are worn, then you’ll have too
much fluid when you get new brake
linings. You should add (or remove)
brake fluid, as necessary, only when work
is done on the brake hydraulic system. When your brake fluid falls to a
low level, your brake warning light,
“SERVICE ABS” light and “SERVICE
ASR” light will come on. Also, the
anti-lock brake and Acceleration Slip
Regulation systems are disabled. See
“Brake System Warning Light” in the
Index.
What to Add:
When you do need brake fluid, use only
DOT-3 brake fluid
- such as Delco-
Supreme
1 l@ (GM Part No. 1052535).
Use new brake fluid from a sealed
container only, and always clean the brak
fluid reservoir cap before removing it.

NOTICE:
Don’t let someone put in the
wrong kind of fluid. For example,
just a few drops of mineral-based
oil, such as engine oil, in your
brake system can damage brake
system parts
so badly that they’ll
have to be replaced.
Brake fluid can damage paint,
so
be careful not to spill brake fluid
on your vehicle. If you
do, wash it
off immediately. See “Appearance
Care” in the Index.
Brake Wear
Your Corvette has four-wheel disc brakes.
Disc brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads are
worn and new pads are needed. The
sound may come and go or be heard all
the time your vehicle is moving (except
when you are pushing
on the brake pedal
firmly).
I NOTICE:
I
Continuing to drive with worn-out
brake pads could result in costly brake repair.
Some driving conditions or climates may
cause a brake squeal when the brakes are
first applied or lightly applied. This does not mean something is wrong with your
brakes. Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does
not return to normal height, or if there is
a rapid increase in pedal travel. This
could be a sign of brake trouble.
Brake Adjustment
As you make brake stops, your disc
brakes automatically adjust for wear.
Replacing Brake System Parts
The braking system on a modern vehicle
is complex. Its many parts have to be of
top quality and work well together
if the
vehicle is to have really good braking.
Vehicles we design and test have
top-quality GM brake parts in them, as
your Corvette does when it is new. When
you replace parts of your braking system
- for example, when your brake linings
wear down and you have to have new
ones put in
- be sure you get new
genuine GM replacement parts. If you
don’t, your brakes may no longer work
properly. For example,
if someone puts
in brake linings that are wrong for your
vehicle, the balance between your front
and rear brakes can change, for the worse. The braking performance you’ve come to
expect can change in many other ways
if
someone puts in the wrong replacement
brake parts.

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.
