2001 Oldsmobile Alero tire pressure

6-38 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.
ªColdº 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

Tire overloading

Bad wear

Bad handling

Bad fuel economy.
NOTICE: (Continued)
NOTICE: (Continued)
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 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.

6-39 Tire Pressure Monitor System (If Equipped)
The tire pressure monitor system can alert you to a large
change in the pressure of one tire. The system ªlearnsº the
pressure at each tire throughout the operating speed range
of your vehicle. The system normally takes between
45 and 90 minutes of driving to learn the tire pressures.
This time may be longer depending on your individual
driving habits. Learning need not be accumulated during
a single trip. Once learned, the system will remember the
tire pressures until the system is reset.
After the system has learned tire pressures with properly
inflated tires, the LOW TIRE PRESSURE light will come
on if the pressure in one tire becomes 12 psi (83 kPa) lower
than the other three tires. The tire pressure monitor system
won't alert you if the pressure in more than one tire is low,
if the system is not properly calibrated, or if the vehicle is
moving at less than 15 mph (25 km/h), faster than 75 mph
(120 km/h), on rough roads or during turns. The light may
also come on if you are driving on partially cleared
pavement or on gravel roads.
The tire pressure monitor system detects differences in tire
rotation speeds that are caused by changes in tire pressure.
The system can alert you about a low tire
-- but it doesn't
replace normal tire maintenance. See ªTiresº in the Index.If the anti
-lock brake system warning light comes on,
the tire pressure monitor system may not be working.
See your dealer for service. Also, see ªAnti
-Lock Brake
System Warning Lightº in the Index.
When the LOW TIRE PRESSURE light comes on, you
should stop as soon as you can and check all your tires for
damage. If a tire is flat, see ªIf a Tire Goes Flatº in the
Index. Also check the tire pressure in all four tires as soon
as you can. See ªInflation
- Tire Pressureº in the Index.
The light will come on and stay on, when the ignition is
ON, until the tire pressure condition is corrected and
you RESET the system. The light may come on and then
go out when driving on partially cleared pavement or on
gravel roads. Under these conditions, you do not need to
reset the tire pressure monitor.
Don't reset the tire pressure monitor system without first
correcting the cause of the problem and checking and
adjusting the pressure in all four tires. If you reset the
system when the tire pressures are incorrect, the system
will not work properly and may not alert you when a
tire is low.

6-40
Any time you adjust a tire's pressure, rotate your tires,
have one or more tires repaired or replaced, or when any
work is done on your vehicle where tires are removed
you'll need to reset (calibrate) the tire pressure monitor
system. You'll also need to reset the system whenever
you buy new tires and whenever the vehicle's battery
has been disconnected.
To reset (calibrate) the system:
1. Turn the ignition switch to ON (engine not running).
2. Press and release the RESET button located inside
of the driver's side instrument panel fuse block.
The CHANGE OIL light will begin to flash.
3. Press and release the RESET button again.
The CHANGE OIL light will go off, and the
LOW TIRE PRESSURE light will start flashing.
4. When the LOW TIRE PRESSURE light is flashing,
press and hold the RESET button until the
chime sounds.
If the LOW TIRE PRESSURE light doesn't go off,
repeat the procedure. If the LOW TIRE PRESSURE
light still remains on, see your dealer for service.
The system completes the calibration process
during driving.The system normally takes 15 to 20 minutes of driving in
each of three speed ranges to ªlearnº tire pressures. The
speed ranges are 15 to 40 mph (25 to 65 km/h), 40 to
65 mph (65 to 105 km/h) and above 65 mph (105 km/h).
When learning is complete, the system will alert you after
2
-8 minutes if a tire is 12 psi (83 kPa) different from the
other three tires. Detection thresholds may be higher and
detection times may be longer on rough roads, curves and
at high speeds. The system is not capable of detection at
speeds greater than 75 mph (120 km/h).
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 ªWhen It's Time for New Tiresº and
ªWheel Replacementº 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 ªScheduled
Maintenance Servicesº in the Index for scheduled
rotation intervals.

6-41
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. Reset the LOW TIRE PRESSURE
light. Make certain that all wheel nuts are properly
tightened. See ªWheel Nut Torqueº in the Index.
CAUTION:
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 ªOwner Checks and Servicesº and ªPeriodic
Maintenance Inspectionsº following.Footnotes

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.
@ Whenever the tires are rotated, the Tire Pressure
Monitor System (if your vehicle is so equipped) must
be reset.
+ A good time to check your brakes is during tire
rotation. See ªBrake System Inspectionº under
ªPeriodic Maintenance Inspectionsº in Part C of
this schedule.

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
perform these underhood checks at each fuel fill.
