Check Tire Pressure System - Buick 2003 LeSabre Owner's Manual

Check Tire Pressure System
If your vehicle has the check tire pressure system,
it can alert you to a large change in the pressure of one
tire. The system won't alert you before you drive that
a tire is low or flat. You must begin driving before
the system will work properly.
The CHECK TIRE PRESSURE message will appear
on the Driver Information Center (DIC) if pressure
difference (low pressure) is detected in one tire.
The check tire pressure system may not alert you if:
more than one tire is low,
0
the vehicle is moving faster than 65 mph (105 km/h),
the system is not yet calibrated,
0
the tire treadwear is uneven,
the compact spare tire is installed,

If the anti-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. Also, see
Anti-Lock Brake System Warning Light
on
page 3-39.
The check tire pressure 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 Tires on page 5-61.
When the CHECK TIRE PRESSURE message appears
on the Driver Information Center, you should stop as
soon as you can and check all your tires for damage.
If a tire is flat, see If a Tire Goes Flat on page 5-70.
Also check the tire pressure in all four tires as soon as
you can. See Inflation
-
Tire Pressure on page 5-62.
Any time you adjust a tire's pressure or have one or more
tires repaired or replaced, you'll need to reset (calibrate)
the check tire pressure system. You'll also need to reset
the system whenever you rotate the tires, buy new tires
and install or remove the compact spare.
