Automatic Transmission Fluid
Operating the engine with the air cleaner off can
cause you or others
to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine
backfires.
If it isn't there, and the engine
backfires, you could be burned. Don't drive with
it
off, and be careful working on the engine with
the air cleaner
off.
I NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which
will damage it. Always
have the air cleaner
in place when you're driving.
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid
and filter every 50.000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi. police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
See "Scheduled Maintenance Services"
in the Index.

Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in YOLK manual
transmission doesn't require changing.
How to Check
Because this operation can be a little dii'licult, you
may choose to have this done at your GM dealership
Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get
false reading.
NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a
fire. Be
~ sure to get an accurate reading if you check your
~ transmission fluid.

Brake Pedal Travel
See your dealer if the brake pedal does not return to
nor~nal height, or
if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
If your brake pedal goes down farther than normal. your
rear drum brakes may need adjustment. Adjust them
by
backing up and firmly app1yin.g the brakes a lew times.
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.
Your vehicle was designed and tested
with top-quality
GM brake parts. When
you replace parts of your braking system
-- for
example, when your brake linings wear down and you
haw to have new ones
put in -- be sure you get new
approved
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.
Battery
Every new vehicle has a Delco Freedom@ battery. You
never have to add water to one of these. When it’s time
for a new battery, we recomlnend a Delco Freedom
battery. Get one that has the replacement number shown
on the original battery‘s label.

If your vehicle has a compact spare tire, don’t include it
in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the
Certificatioflire label. Make certain that all wheel nuts
are properly tightened. See “Wheel Nut Torque’’ in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make 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
“Changing a Flat Tire” in the Index.)
