Ifa Tire Goes Flat
It’s unusual for a tire to “blow OU~,)
while you’re driving, especially if you
maintain your tires properly. If air goes
out of a tire, it’s much more likely to
leak out slowly. But
if you should ever
have a “blowout,” here are a few tips
about what to expect and what to do:
If a front tire fails, the flat tire will
create a drag that pulls the vehicle
toward that side. Take your foot
off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, then gently brake to a stop
well out of the traffic lane.
A rear blowout, particularly on a curve,
acts much like a
skid and may require
the same correction you’d use in a
skid.
In any rear blowout, remove your foot
from the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It may
be very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If your tire goes flat, the next section
shows how
to use your jacking
equipment to change a
flat tire safely.

Gasolines for Cleaner Air
Your use of gasoline with detergent
additives will help prevent deposits
from forming in your engine and fuel
system. That helps keep your engine in
tune and your emission control system
working properly. It’s good for your
vehicle, and you’ll be doing your
part
for cleaner air.
Many gasolines are now blended with
materials called oxygenates. General
Motors recommends that you use
gasolines with these blending materials,
such as MTBE and ethanol. By doing
so, you can help clean the air, especially
in those parts of the country that have
high carbon monoxide levels. In
addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolines are specially designed
to reduce vehicle emissions. General
Motors recommends that you use
reformulated gasoline.
By doing so, you
can help clean the air, especially in
those
parts of the country that have
high ozone levels.
You should ask your service station
operators
if their gasolines contain
detergents and oxygenates, and if they
have been reformulated to reduce
vehicle emissions.
I
Fuels in Foreign Countries
If you plan on driving in another
country outside the
U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use
even one tankful, your emission
controls won’t work well or at all. With
continuous use, spark plugs can get
fouled, the exhaust system
can corrode,
and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor
will be damaged.
All of that means
costly repairs that wouldn’t be covered
by your warranty.

Automatic Transaxle Fluid (CONT.)
How to Add Transaxle Fluid:
Refer to the Maintenance Schedule to
determine what kind of transaxle fluid
to use. See the
Index under Fluids G
Lubricants. If the fluid level is low, add
only enough of the proper fluid
to bring
the level into the cross-hatched area on
the dipstick.
It doesn’t take much fluid, generally less
than a pint
(0.5 L). Don’t overfill.

We recommend you use only fluid
labeled DEXRON@-IIE, because fluids
with that label are made especially for
your automatic
transaxle. Damage
caused by fluid other than DEXRON@-IIE
is not covered by your new vehicle
warranty.
After adding fluid, recheck the fluid
level
as described under How to Check.
When the correct fluid level is obtained’
push the dipstick back in
all the way.

Downloaded from www.Manualslib.com manuals search engine 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.
Tire Inspection and Rotation
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.
Use this rotation pattern.
Mer 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.
I
Rust or dirt on a wheel, or on
the 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.)

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.)
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
Treadwear
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.

Downloaded from www.Manualslib.com manuals search engine Service & Appearance Care
Temperature-A, B, C (CONT.)
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.

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 ycur 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
I
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
I
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 to have the right wheels,
wheel bolts, and wheel nuts for your
Chevrolet model.
