Pontiac 2004 Bonneville, Owner'S Manual

Page: 345 / 446

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 does not replace normal tire
maintenance. See Tires on page 5-58.
When the CHECK TIRE PRESSURE message appears
on the Driver Information Center (DIC) or the systems
monitor 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 on page 5-79. Also
check the tire pressure in all four tires as soon as you
can. See Inflation - Tire Pressure on page 5-67.
Any time you adjust a tire’s pressure or have one or more
tires repaired or replaced, you will need to reset
(calibrate) the check tire pressure system. You will also
need to reset the system whenever you rotate the tires,
buy new tires and install or remove the compact spare.
Do not reset the check tire pressure 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 check tire pressure system will not work properly
and may not alert you when a tire is low or high.
To reset (calibrate) the system with a Driver Information
Center (DIC):
1. Turn the ignition switch to ON.
2. Using the MODE and SELECT buttons, change the
DIC to display TIRE PRESSURE.
3. Press and hold the RESET button for about five
seconds.
4. The display should change to read TIRE
PRESSURE RESET. If TIRE PRESSURE RESET
does not appear on the display after about five
seconds, see your dealer for service.
5. When you release the button after seeing the TIRE
PRESSURE RESET message, the display will
change to read TIRE PRESSURE NORMAL.
