Check Tire Pressure Light
CHECK
TIRE
PRESS
With the check tire pressure
system, after you've driven
10
to 20 miles (1 5 to 30 km)
the CHECK TIRE PRESS
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.
When
the CHECK TIRE
PRESS 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 light will stay on until you turn off the ignition or
press the CALIBRATE TIP9 PRESS button. See
"Check Tire Pressure Syst?
."
in the Index.
If the anti-lock brake system warning light comes on
with the CHECK
TIRE
PRESS light, the check tire
pressure system isn't working. See your Pontiac dealer
for service. (Also, see "Anti-Lock Brake System
Warning Light in the Index.)

SERVICE
ENIGINIE SOON
Your Pontiac is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to assure
that
emissions are at acceptable levels for the life of the
vehicle, helping to produce
a
cleaner environment. (In
Canada, OBD I1 is replaced by Enhanced Diagnostics.)
The SERVICE ENGINE SOON light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system before
any problem is apparent. This may prevent more serious
damage to your vehicle. This system is also designed to
assist your service technician in correctly diagnosing
any malfunction.
