How do you clear "check

To reset the tire pressure system, do the following:

(NOTE!....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.)

1. With the engine off, turn the ignition to ON.
2. Press the MODE button until the DIC reads LOW
TIRE PRESSURE HOLD SET TO RESET.
3. Press and hold the SET button until you hear a
chime, and TIRE PRESSURE RESET is displayed.

You will hear three chimes, then the LOW TIRE
PRESSURE message will go off and the DIC will return
to TIRE PRESSURE NORMAL. If the LOW TIRE
PRESSURE message comes back on, the check tire
pressure system has not reset. Repeat the procedure.
The system completes the calibration process during
driving. The system learns the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 30 and 60 minutes of
driving to learn the tire pressures. The system normally
takes 10 to 20 minutes of driving in each speed range to
learn tire pressures. The speed ranges are 20 to 40 mph
(32 to 64 km/h), 40 to 60 mph (64 to 96 km/h), and above
60 mph (96 km/h). This time may be longer depending on
your individual driving habits. The learning process does
not need to be completed during a single trip. Once
learned, the system will remember the tire pressure until
the system is reset.

You need to put a scanner on the computer and read the codes, then repair the codes called for and using the scanner clear the codes and you will be ok. The button on the message center doesn't reset the computer it just clears the code from the screen.

After checking air pressure and adding air if needed, hold the RESET button in 10-20 seconds and it should clear the Check Tire Pressure light.

Hi, this car has a flat tire repair system and run-flat tires rather than a spare tire. The warning you are getting is the standard warning when low pressure is detected in one of the tires. Just check all the tires for proper pressure and if the warning continues, try to reset it using the menus.

One of the sensors in the tires is faulty, or the battery in the sensor is bad. Tire shop can take car of that for ya.

Sounds like you will need the transmitting unit replaced - it is located behind the stem inside the tire...

TIRE MON (Tire Inflation Monitor Reset)
This feature allows you to reset the tire pressure monitor after checking all tire pressures. To clear the LOW TIRE PRESSURE light from the instrument panel cluster and reset the low tire pressure monitor do the following:

1. Scroll, using the SEEK/PSCAN up or down arrows, until TIRE MON appears on the display.
2. Press the PREV or NEXT button to enter the submenu. RESET will be displayed.
3. Press the TUNE/DISP button to reset. A chime will be heard to verify the new setting and DONE will be displayed for one second.

The low tire pressure monitor is now reset.

Two things, first try another tire guage, second the sensor is bad. these can cost up to $80.00.
Replace the sensor or ignore the light and keep check on the tire pressure.

have you checked your pressures ?????

Must have codes for check engine light cleared with scan tool. Check all tire pressures and road test up to 35 mph. Tire message should clear if low tire was problem. If light for tires remains then possible radio frequency sensor problem. Sensor replacement may be necessary. Sensors have alkaline non-serviceable batteries. If battery is dead sensor will have to be replaced.
