1997 Oldsmobile Aurora change time

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.
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.
Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle 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:
0 In heavy city traffic where the outside temperature
regularly reaches
90 OF (32 O C) or higher.
In hilly or mountainous terrain.
0 When doing frequent trailer towing.
0 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.

Brake Ad-iustment
NOTICE:
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.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly torque wheel nuts in the
proper sequence to GM specifications.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection”
in Section 7 of this manual
under
Part C “Periodic Maintenance Inspections.”
Brake Pedal Travel
See your retailer 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. Every
time you apply the brakes, with or without the
vehicle moving, your brakes 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.
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 have 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.

After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the Tire-Loading
Information 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.) When
It’s Time for New Tires
r
L
I 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
1/16 inch (1.6 mrn) or
less of tread remaining.
You need a new tire if any
of the following statements
are true:
0
0
0
0
You can see the indicators at three or more places
around
the tire.
You can see cord or fabric showing through the
tire’s rubber.
The tread
or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
The tire has a bump, bulge or split.

Short TripKity Maintenance Schedule
The services shown in this schedule up to 100,000 miles
(166
000 krn) should be performed after 100,000 miles
(166
000 km) at the same intervals. The services shown
at 150,000 miles (240
000 km) should be performed at
the same interval after 150,000 miles (240
000 km).
See “Owner Checks and Services” and “Periodic
Maintenance Inspections” following.
Footnotes
-f The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to the
completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.
# Lubricate the suspension and steering linkage,
transaxle shift linkage, parking brake cable guides and
underbody contact points and linkage.
* 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 krn) or 12 months,
(whichever occurs first), 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. Remember to reset the Oil Life Monitor
when the oil has been changed. For more information, see “Engine Oil Life Monitor” in the Index.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection’’ under “Periodic
Maintenance Inspection” in Part
C of this schedule.
