Tire Pressure Monitor Light
LOW
TI RE
The tire pressure monitor
system can alert you to
a
large change in the pressure
in
one tire. The system
won’t alert you before you
drive that a tire is low or
flat. Each time you start
your Buick, you must drive
10 to
20 miles (15 to 30 km)
before the system will
work properly.
After you’ve driven
10 to 20 miles (15 to 30 km), the
LOW TIRE light will come on if the pressure in one tire
becomes at least 10 psi
(69 kPa) higher or lower than the
other three tires. The tire pressure monitor system
detects differences in tire rotation speeds that are caused
by changes in tire pressure. It will not alert you
if the
pressure in more than one tire is low or high or
if the
system is not calibrated properly.
The system can alert
you about a low tire
-- but it doesn’t measure tire
pressure, and it doesn’t replace normal tire maintenance.
See “Tires’’
in the Index.
When the LOW TIRE light comes
on, 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” in the Index.)
Also, check the tire pressure in all four tires as soon
as
you can. (See “Inflation - Tire Pressure” in the Index.)
The
LOW TIRE light will
stay on until you turn off
the ignition or press the red
RESET button, which is
located inside your
instrument panel fuse block.
(It’s the first button in
the
top row of the fuse block.)
Don’t press the RESET button without first checking
and adjusting the pressure in all four tires.
If you press
the button when the tire pressure is incorrect,
the check
tire pressure system will not work properly
and may
not alert you when a tire is low.
Any time
you adjust the tire pressure, you’ll need to
calibrate the check tire pressure system.
You’ll also neea
to calibrate the system whenever you buy new tires,
have tires repaired or rotate your tires.

the indicator may come on before
3,000 miles (5 000 km). Never drive your vehicle more
