If a Tire Goes Flat Changing a Flat Tire
It’s unusual for a tire to “blow out” while you’re driving, If a tire goes flat, avoid further tire and wheel damage
especially
if you maintain your tires properly. If air goes by driving slowly to a level place. Turn on your hazard
out of a tire, it’s much more likely to leak out slowly. warning fla\
shers.
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, and 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 a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely. Changing
a tire
can cause an injury. The vehicle
can slip
off the jack and roll over you or other
people. You and they could be badly injured.
Find
a level place to change your tire. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transaxle shift lever in
PARK (P), or shift a manual transaxle to
FIRST (1) or REVERSE (R).
3. lbrn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire
on the other side of the
vehicle,
at the opposite end.

Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
0 When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is 180°F to 200°F
(82°C to 93°C).
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F ( lO"C), you may have
to drive longer.
Checking the Fluid Level
Park your vehicle on a level place. Keep the

in
PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the shift
lever
in PARK (P).
Let the engine run at idle for three to five minutes.
Then, without shutting off the engine, follow
these steps:
1. The automatic transaxle dipstick handle is red.
Pull out the dipstick and wipe it with a clean rag or
paper towel.
2. Push it back in all the way, wait three seconds and
then pull it back out again.

3. Check both sides of the dipstick, and read the
lower level. The fluid level must be
in the
cross-hatched area.
4. If the fluid level is in the acceptable range, push the
dipstick back
in all the way.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use.
See “Recommended
Fluids and Lubricants” in the Index. 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.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring
it to the proper level.
It doesn’t
take much fluid, generally less than one
pint
(0.5 L). Don ’t overj?ZZ.

We recommend you use only fluid labeled
DEXRON@-111, because fluid with that label is
made especially for your automatic transaxle.

A CAUTION:
Mixing tires could cause you 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.
Using tires
of different sizes may also cause
damage to
your vehicle. 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 use
on your vehicle.

A CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim flanges could develop cracks after
many miles
of driving. A tire and/or wheel could
fail suddenly, causing
a crash. Use only radial-ply
tires
with the wheels on your vehicle.
Uniform 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.) The
grades are molded on the sidewalls
of most passenger
car tires. The Uniform
Tire Quality Grading system does
not apply to deep tread, winter-type snow tires,
space-saver or temporary use spare
tires, tires with
nominal rim diameters
of 10 to 12 inches (25 to 30 cm),
or to some limited-production tires.
While the tires available on General Motors passenger cars and light
trucks may vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.

Treadwear Temperature -- A, B, C
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
(1 112) 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, and 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. 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 faiIure.
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.
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.
