inflation pressure Oldsmobile Aurora 1998 Owner's Manuals

Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and
it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.

INFORMATION
Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label,
found on the rear edge
of the driver’s door, tells you the
proper size, speed rating and recommended inflation
pressure
for the tires on your vehicle. It also gives you
important information about the number of people that
can be in your vehicle and the total weight that you can
carry. This weight is called the Vehicle Capacity Weight
and includes the weight of all occupants, cargo, and all
nonfactory-installed options.

Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi
(420 kPa).
After installing the compact spare on your vehicle, you
should stop as
soon as possible and make sure your
spare tire is correctly inflated. The compact spare is
made to perform well at speeds up to
65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full-size tire
repaired or replaced where you want. Of course,
it’s best
to replace your spare with
a full-size tire as soon as you
can. Your spare will last longer and be in good shape in
case you need it again.
NOTICE:
When the compact spare is installed, don’t take
your vehicle through an automatic vehicle wash
with guide rails. The compact spare can get
caught on the rails. That can damage the tire and
wheel, and maybe other parts
of your vehicle.
Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire and its wheel together.
NOTICE:
~- ~~~~ ~~~ ~~ ~~~ ~~ ~~

Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t use tire chains on your
compact spare.

Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to be
cut, punctured or broken by
a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents.
If your
tread is badly worn, or
if your tires have
been damaged, replace them.
I
Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the
rear edge of the driver’s
door, shows the correct
inflation pressures for your tires when they’re cold.
“Cold”
means your vehicle has been sitting for at least
three hours
or driven no more than 1 mile (1.6 km).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation
is all right. It’s not. If your tires
don’t have enough
air (underinflation), you can
get the following:
Too much flexing
Too much heat
0 Tire overloading
Bad wear
0 Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.

!

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 Wa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or wheels.
See “When It’s Time for New Tires” and
“Wheel
Replacement” later in this section for more information.
The purpose
of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals. When
rotating your tires, always use the correct
rotation pattern shown here.
Don’t include the compact spare tire in your
tire rotation.
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.

Part B: Owner Checks and Services
Listed below are owner checks and services which
should be performed at the intervals specified to help
ensure the safety, dependability and emission control
performance of your vehicle.
Be sure any necessary repairs are completed at once.
Whenever any fluids or lubricants are added to your
vehicle, make sure they
are the proper ones, as shown
in
Part D.
At Each Fuel Fill
It is important for you or a service station attendant to
peq5orm these underhood checks at each
fuel fill.
Engine Oil Level Check
Check the engine oil level and add the proper oil
if necessary. See “Engine Oil” in the Index for
further details.
Engine Coolant Level Check
Check the engine coolant level and add DEX-COOL@
coolant mixture if necessary. See “Engine Coolant” in
the Index for further details.
Windshield Washer Fluid Level Check
Check the windshield washer fluid level in the
windshield washer tank and add the proper fluid if
necessary. See “Windshield Washer Fluid” in the
Index for further details.
At Least Once a Month
Tire Inflation Check
Make sure tires are inflated to the correct pressures.
See “Tires” in the Index for further details.
Cassette Deck Service
Clean cassette deck. Cleaning should be done every
50 hours of tape play. See “Audio Systems” in the
Index for further details.
Power Antenna Service
Clean power antenna mast. See “Audio Systems” in
the Index for further details.
