Power Steering Fluid (CONT.)
What to Add:
Refer to the Maintenance Schedule to determine what kind of fluid to use. See
the
Index under Fluids & Lubricants.
When adding power steering fluid
or making a complete fluid change,
always use the proper fluid. Failure
to use the proper fluid can cause
leaks and damage hoses and seals.

Windshield Washer Fluid
To Add:
Open the cap labeled WASHER
FLUID ONLY. Add washer fluid until
the bottle is full.
When using concentrated washer
fluid, follow the manufacturer’s
instructions for adding water.
Don’t mix water with ready-to-
l15e washer fluid. Water can
use the solution
to freeze and
. .tmage your washer fluid tank
and other parts of the washer
system.
Also, water doesn’t clean
s well as washer fluid.
Fill your washer fluid tank on14
?4 full when it’s very cold. Thir
allows for expansion, which
could damage the
tank if it is
completely
full
Don’t use radiator antifreeze
your windshield washer.
It can
damage your washer system an(
paint.

Brake Master Cylinder (CONT.)
When your brake fluid falls to a low
level, your brake warning light will
come
on. See the Index under Brake
System Warning Light.
What to Add: When you do need brake
fluid, use only DOT-3 brake fluid-such
as Delco Supreme
ll@ (GM Part No.
1052535). Use new brake fluid from a
sealed container only.
122
DOT-5 silicone brake fluid can
damage your vehicle. Don’t use it.
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 ‘.nt, so
be careful not to spill brae fluid
on your vehicle.
Replacing Brake System parfs
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
Chevrolet 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

Loading Your Vehicle (CONI:)
the GVWR (Gross Vehicle Weight
Rating). The GVWR includes the
weight of the vehicle, all occupants, fuel
and cargo. Never exceed the GVWR for
your vehicle, or the Gross Axle Weight
Rating (GAWR) for either the front or
rear axle.
And,
if you do have a heavy load, you
should spread
it out. Don’t carry more
than
132 lbs. (60 kg) in your trunk or
rear area.
128
Do not load your vehicle any
L b heavier than the GVWR or the
maximum front and rear GAWRs.
If
you do, parts on your vehicle
can break, or
it can change the way
your vehicle handles. These could
cause you to lose control. Also,
overloading can shorten the life of
your vehicle. Your
warranty does not cover part
or components that fail beca
: ol
overloading.
If you put things inside your vehicle-
like suitcases, tools, packages, or
anything else-they
will go as fast as the
vehicle goes. If you have to stop or turn
quickly, or
if there is a crash, they’ll
keep going.

lnflation-lire Pressure
The Tire-Loading Information label
which is
on the rear edge of the driver’s
door shows the correct inflation
pressures for your tires, when they’re
cold. “Cold” means your vehicle has
been sitting for at least three hours or
driven no more than a mile. Don’t
let anyone tell you that
underinflation
or overinflation is
all right. It’s
not. If your tires don’t
have enough
you can get:
Too much flexing
Too much heat
Tire overloading
Bad weLA
Bad handling
Bad fuel economy. ition)
If your tires have too much air
(overinflation), you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road
hazards.
When to Check:
Check your tires once a month or more.
Don’t forget your compact spare tire. It
should be at
60 psi (420 kpa).
How to Check:
Use a good quality pocket-type gage to
check tire pressure. Simply looking at
the tires will not tell you the pressure,
especially if
you have radial tires-
which may look properly inflated even if
they’re underinflated.
If your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.

Downloaded from www.Manualslib.com manuals search engine Tire hspection and Rotation I
Use this rotation pattern.
After the tires have been rotated, adjust
the front and rear inflation pressure as
shown on the Tire-Loading Information
label. Make certain that all wheel nuts
are properly tightened. See the Index
under Wheel Nut Torque.
To make your tires last longer, have
them inspected and rotated at the
mileages recommended in the
Maintenance Schedule. See the
Index
under Scheduled Maintenance Services.
u I I’ -
Rust or dirt on a wheel, or on
; parts to which it is
fastened, can make the wheel nuts
become loose after a time. The
wheel could come off and cause an
accident. When you change a
wheel, remove any rust or dirt
from
places where the wheel
attaches to the vehicle. In an
emergency, you can use a cloth or
a paper towel to do this; but be
sure to use a scraper or wire brush
later, if you need to, to get all the
rust or dirt
off. (See the Index
under Changing a Flat Tire.)
When lt’s Time for New Tires
One way to tell when it’s time for new
tires
is to check the treadwear
indicators, which will appear when your
tires have
only 2/32 inch (1.6 mm) or
less of tread remaining.
You need a new tire if

Buying New Tires
To find out what kind and size of tires
you need, look at the Tire-Loading
Information label.
The tires installed on your vehicle when
it was new had a Tire Performance
Criteria Specification (TPC Spec)
number on each tire’s sidewall. When
you get new tires, get ones with that
same
TPC Spec number. That way, your
vehicle will continue to have tires that are designed to give proper endurance,
handling, speed rating, traction, ride
and other things during normal service
on your vehicle. If your tires have an all- season tread design, the TPC number
will be followed by a
“MS” (for mud
and snow).
If you ever replace your tires with those
not having a TPC Spec number, make
sure they are the same size, load range,
speed rating and construction type (bias,
bias-belted or radial) as your original
tires.
Mixing tires could cau’se you
d to lose control while driving.
If you mix tires of different sizes
or types (radial and bias-belted
tires), the vehicle
may not handle
properly,
and you could have a
crash. Be sure to use the same size
and type tires on all wheels. It’s all
right to drive with your compact
spare, though. It was developed for
limited use on your vehicle.

Unijiorpn Tire Quality
Grading
The following information relates to the
system developed by the United States
National Highway Traffic Safety
Administration which grades tires by
treadwear, traction and temperature
performance. (This applies only to vehicles sold in the United States.)
232

Downloaded from www.Manualslib.com manuals search engine Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one and a half
(1%) times as well
on the government course as a tire
graded
100. The relative performance of
tires depends upon the actual conditions
of their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
Traction-A, B, C
The traction grades, from highest to
lowest are:
A, B, and C. They represent
the tire’s ability
to stop on wet pavement
as measured under controlled conditions
on specified government test surfaces of
asphalt and concrete.
A tire marked C
may have poor traction performance.
Warning: The traction grade assigned
to this tire
is based on braking (straight-
ahead) traction tests and does
not
include cornering (turning) traction.
Temperature-A, B, C
The temperature grades are A (the
highest),
B, and C, representing the
tire’s resistance to the generation of heat
and its ability to dissipate heat when
tested under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive
temperature can lead
to sudden tire
failure. The grade
C corresponds to a
level of performance which all
passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent
higher levels of performance
on the
laboratory test wheel than the minimum
required
by law.
233

Downloaded from www.Manualslib.com manuals search engine Service & Appearance Care
Temperature-A, 8, C ~NTJ
Warning: The temperature grade for
this tire is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation,
or
excessive loading, either separately or in
combination, can cause heat buildup
and possible tire failure.
Those grades are molded on the
sidewalls of passenger car tires.
While
the tires available as standard or
optional equipment on General Motors
vehicles may vary
with respect to these
grades, all such tires meet General
Motors performance standards and have
been approved for use on General Motors vehicles.
All passenger type
(P Metric) tires must conform to Federal
safety requirements in addition to these
grades.
234
Wheel Alignment and
Tire Balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you
will not need to have
your wheels aligned again. However,
if
you notice unusual tire wear or your
vehicle pulling one way or the other, the
alignment may need to be reset. If you
notice your vehicle vibrating when
driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked
or badly rusted. If wheel nuts keep
coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced. If
the wheel leaks air out, replace
it
(except some aluminum wheels, which
can sometimes be repaired). See your
Chevrolet dealer if any of these
conditions exist.
Your dealer
will know the kind of wheel
you need. Each new wheel should have
the same load carrying capacity,
diameter, width, offset, and be mounted
the same way as the one
it replaces.
If you need to replace any of your
wheels, wheel bolts, or wheel nuts,
replace them only
with new GM
original equipment parts. This way, you
will be sure you have the right wheel,
wheel bolts, and wheel nuts for your
Chevrolet model.
