1997 Oldsmobile Aurora torque

Torque Lock
If you are parking on a hill and you don’t shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. You may find it difficult to pull the shift
lever out of PARK (P). This is called “torque lock.”
To
prevent torque lock, set the parking brake and then shift
into PARK (P) properly before you leave the driver’s
seat. To find out how,
see “Shifting Into PARK (P)” in
the Index.
When you are ready
to drive, move the shift lever out of
PARK (P)
before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some
of the
pressure from the parking pawl in the transaxle,
so you
can pull the shift lever out
of PARK (P).
Shifting Out of PARK (P)
Your Aurora has a brake-transaxle shift interlock. You
have
to fully apply your regular brake before you can
shift from PARK (P) when the ignition is
in the RUN
position. See “Shifting the Automatic Transaxle” in
the Index.
If you cannot shift out of PARK (P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK (P) as you maintain brake application. Then
move the shift lever into the gear you wish. Press the
shift lever button before moving the shift lever.
If you ever hold the brake pedal down but still can’t
shift out
of PARK (P), try this:
1.
2.
3.
4.
5.
Turn the ignition key to OFF. Open and close the
driver’s door to turn off
the Retained Accessory
Power feature.
Apply and hold the brake until
the end of Step 4.
Shift to NEUTRAL (N).
Start the vehicle and then shift to the drive gear
you want.
Have the vehicle fixed as
soon as you can.

11. Using the wheel
wrench, tighten the
wheel nuts firmly in
a crisscross sequence
as shown.
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come
off. This could lead to an accident.
Be sure to use the correct wheel nuts.
If you have
to replace them, be sure to get new
GM original
equipment wheel nuts.
Stop somewhere
as soon as you can and have the
nuts tightened with
a torque wrench to 100 Ib-ft
(140 N-m).
NOTICE:
Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper torque specification.
12. Then replace the wheel cover. Be sure to position
the alignment pin
on the cover with the notch in the
wheel. Apply pressure around the edge
of the cap to
snap it in place.
Don’t try
to put the wheel cover on the compact
spare tire. It won’t
fit. Store the wheel cover in the
trunk until you have replaced the compact spare tire
with a regular tire.
I NOTICE:
Wheel covers won’t fit on your compact spare. If
you try to put a wheel cover on your compact
spare,
you could damage the cover or the spare.

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.
