When using concentrated washer fluid, follow the
manufacturer’s instructions
for adding water.
Don’t mix water with
ready-to-use washer fluid.
Water can cause the solution to
freeze and damage your washer
fluid tank and other parts of the
washer system. Also, water
doesn’t clean as well as washer
fluid.
Fill your washer fluid tank only
314 full when it’s very cold.
This allows for expansion,
which could damage
the tank
if it is completely full.
Don’t use radiator antifreeze in
your windshield washer. It can
damage your washer system
and paint.
>wise Control
Vith Cruise Control, you can maintain a
peed of about 25 mph (40 km/h) or
nore without keeping your foot on the
ccelerator. This can really help on long
ips. Cruise Control does not work at
peeds below about
25 mph (40 kmh).
Vhen you apply your brakes or push the
lutch pedal, or if ASR is active, the
bise Control shuts off.
To Set Cruise Control
1. Turn the Cruise Control switch on.

What can you do about highway
hypnosis? First, be aware that
it can
happen.
Then here are some tips:
0 Make sure your vehicle is well
ventilated, with a comfortably cool
interior.
0 Keep your eyes moving. Scan the road
ahead and to the sides. Check your
rearview mirrors and your instruments
frequently.
0 If you get sleepy, pull off the road into
a rest, service, or parking area and
take a nap, get some exercise, or both.
For safety, treat drowsiness on
the
highway as an emergency.
Hill and Mountain
Roads
Driving on steep hills or mountains is
jifferent from driving in flat or rolling
terrain. If you drive regularly in steep
zountry, or if you’re planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape.
Check all fluid levels and also the
brakes, tires, cooling system and
transmission. These parts can work
hard on mountain roads.
Know how to go down hills. The most
important thing to know is this: let
your engine do some
of the slowing
down. Shift to a lower gear when you
go down a steep or long hill.
0 Know how to go uphill. You may
want to shift down to a lower gear.
The lower gears help cool your engine and transmission, and you can climb
the hill better.

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.

this GM Standard. You should
look for and use only an oil that
meets GM Standard GM4718M.
To determine the preferred
viscosity for your vehicle’s
engine (e.g.,
SAE 5W-30 or SAE
10W-30), see “Engine Oil” in
the Index.
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.

small cracks in individual ribs
without affecting performance.)
