inflation pressure OLDSMOBILE BRAVADA 1998 Owners Manual

Loading Your Vehicle
The Certificationnire label is found on the driver’s door
edge, above the door latch. The label shows the size of
your original tires and the inflation pressures needed to
obtain the gross weight capacity of your vehicle. This is
called the Gross Vehicle Weight Rating (GVWR). The
GVWR includes the weight
of the vehicle, all occupants,
fuel, cargo and trailer tongue weight,
if pulling a trailer. The
Certificatioflire label also tells you the maximum
weights for the front and rear axles, called Gross Axle
Weight Rating (GAWR).
To find out the actual loads on
your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your retailer can help
you with this. Be sure to spread out your load equally on
both sides of the centerline.
Never exceed the GVWR
for your vehicle, or the
GAWR for either the front
or rear axle.
If you do have a heavy load, you should spread it out.
Similar appearing vehicles may have different GVWR’s
and payloads. Please note your vehicle’s
CertificationITire label or consult your retailer for
additional details.

A CAUTION: A --
Make sure the tire and carrier are secure.
Driving with the tire or carrier unlatched could
injure pedestrians or damage the vehicle.
Compact Spare Tire (If Equipped)
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 Wa).
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.

Inflation -- Tire Pressure
The CertificatiodTire label, which is on the driver’s
door edge, above the door latch, 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 (I .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
0 Too much heat
Tire overloading
0 Bad wear
0 Bad handling
0 Bad fuel economy.
NOTICE: (Continued)
I NOTICE: (Continued) I
If your tires have too much air (overinflation),
you can get the following:
0 Unusual wear
Bad handling
0 Rough ride
0 Needless damage from road hazards.
When to Check
Check your tires once a month or more. Also, check the
tire pressure
of the spare tire.
If you have a compact spare tire, it should be at
60 psi (420 kPa).
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 I3 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
lrniform 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.
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
CertificatiodTire 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.)

Part D.
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 1,evel 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 cosrect 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
