Tire warning light won't go off - Tires are correct pressure

By operating the tire pressure warning system reset switch, tire pressure warning system ECU can be set to issue a warning at an inflation pressure that corresponds with the type of tires.
Operate the tire pressure warning system reset switch only after the inflation pressures of all 4 tires have been adjusted on the vehicle.
To initialize the system, press and hold the tire pressure warning system reset switch for 3 seconds or longer with the power switch turned IG-ON. When starting the initialization, the tire pressure warning light blinks 3 times at 0.5 Hz.
During the initialization, the tire pressure warning system valve & transmitter measures the inflation
pressure of the tires, and registers the signals that are transmitted into the ECU at a frequency of 1 per
minute. The initialization process is completed when the signals from the tires have been received.
Once the tire pressure warning system reset switch has been pressed, do not turn the Ignition switch OFF for a few minutes.

Hi, the tire pressure monitor detects any changes in the tire inflation pressure. Therefore, it must initialize and store it in its memory if the tires or wheels have been replaced, re-inflated or the tires have been rotated. You can re-initialize the system by following these steps:

1. Check and make sure that your tires are inflated to the correct pressure

2. Turn the ignition switch to the ON position. If the low tire pressure warning light comes on, push and hold the tire pressure warning reset switch (in the glove box) until the warning light turns off and then release the switch.

3. Now press and hold the tire pressure warning reset switch until the low tire pressure warning light blinks three times.

4. Initialization is *not* completed until driving at the vehicle speed of 19 mph or over for more than one hour. the tire pressure monitoring starts when initialization is completed.

TIRE PRESSURE MONITOR SYSTEM
The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. If your vehicle has this feature, sensors are mounted on each tire and wheel assembly, except the spare tire. The TPMS sensors monitor the air pressure in your vehicle's tires and transmit tire pressure readings to a receiver located in the vehicle.

The TPMS is designed to alert the driver, if a low tire pressure condition exists. This system also allows the driver to check tire pressure levels using the Driver Information Center (DIC).

When a low tire pressure condition is detected, the TPMS displays the "CHECK TIRE PRESSURE" warning message on the DIC, and at the same time illuminates the low tire pressure warning symbol.

You may notice, during cooler weather conditions, that the tire pressure monitor light, located on the instrument panel cluster, and the "CHECK TIRE PRESSURE" message will appear when the vehicle is first started and then turn off as you start to drive the vehicle. This could be an early indicator that the tire pressures are getting low and need to be inflated to the proper pressure.

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated.

Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

The "CHECK TIRE PRESSURE" warning message and low tire pressure light (telltale) will appear at each ignition cycle until the tires are inflated to the correct inflation pressure.

The Tire and Loading Information label (tire information placard) shows the size of your vehicle's original tires and the correct inflation pressure for your vehicle's tires when they are cold.

Your vehicle's TPMS can alert you about a low tire pressure condition but it does not replace normal tire maintenance.

NOTICE: Do not use a tire sealant if your vehicle has Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors.

RESETTING THE TPMS IDENTIFICATION CODES
Each TPMS sensor has a unique identification code. Any time you rotate your vehicle's tires or replace one or more of the TPMS sensors, the identification codes will need to be matched to the new tire/wheel position. Each tire/wheel position is matched to a sensor, by increasing or decreasing the tire's air pressure. The sensors are matched to the tire/wheel positions in the following order: LF TIRE (left front tire on the driver's side of the vehicle), RF TIRE (right front tire on the passengers side of the vehicle), RR TIRE (right rear tire on the passengers side of the vehicle), and LR TIRE (left rear tire on the driver's side of the vehicle).

You will have one minute to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer than one minute, to match the first tire and wheel, or more than five minutes to match all four tire and wheel positions the matching process stops and you will need to start over.

The TPMS sensor matching process is outlined below:

1. Set the parking brake.
2. Turn the ignition switch to "RUN" with the engine off.
3. Turn the headlamp switch from "OFF" to the parking lamps setting four times within three seconds. A double horn chirp will sound and the TPMS low tire warning light will begin to flash. The double horn chirp and flashing TPMS warning light indicate that the TPMS matching process has started. The TPMS warning light should continue flashing throughout the matching procedure. The "SERVICE TIRE MONITOR" message will be displayed on the Driver Information Center (DIC).
4. Start with the driver's side front tire.
5. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for 10 seconds, then stop and listen for a single horn chirp. The single horn chirp should sound within 15 seconds, confirming that the sensor identification code has been matched to this tire and wheel position. If you do not hear the confirming single horn chirp, you will need to start over with Step 1. To let air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage or a key.
6. Proceed to the passenger's side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger's side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver's side rear tire, and repeat the procedure in Step 5.
9. After hearing the confirming horn chirp for the left rear tire, check to see if the TPMS warning light is still flashing. If it is, turn the ignition switch to LOCK to exit the sensor matching process. If the TPMS warning light is not flashing, the five minute time limit has passed and you will need to start the process over beginning with Step 1.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label.
11. Put the valve caps back on the valve stems. The spare tire does not have a TPMS sensor. If you replace one of the road tires with the spare, the "CHECK TIRE PRESSURE" message will be displayed on the DIC screen. This message should go off once you re-install the road tire containing the TPMS sensor. The "SERVICE TIRE MONITOR" message is displayed when the TPMS is malfunctioning. One or more missing or inoperable TPMS sensors will cause the service tire monitor message to be displayed.

That symbol (tire tread) could mean a low tire pressure. The majority of vehicles today have the low tire pressure warning system, which indicates that one or more of the tires are below the minimum tire pressure. Have the tire pressure checked in each tire. As for turning the warning light off, some vehicles the light will go out after tires are inflated properly. Have them check the owner's manual for resetting warning light. Please inform me as to whether or not it was the tires...thanks.

That is the TPMS (tire pressure monitoring system) warning light. It is letting you know that one or more of the tires is low on tire pressure. The correct tire inflation for the vehicle is located on a sticker inside the drivers front door. Make sure all four tires are inflated to that pressure.

If there all low I would bet you live in a cold weather environment. It is normal for tire pressure to drop as temperatures drop.

If one tire is low than it is probably leaking and should be checked for a repair.

Once the tire pressures have been corrected the vehicle will need to be driven for approximately 10 minutes at sustained speeds of more than 15mph.

What may have happened is that one of the tire pressure sensors was damaged, or the system was not reset.
The tire presure sensors use radio frequency to tell the module the tires presure and location. Replacing tires can sometimes damage them. The sensor is part of the valve stem. Use the driver info buttons to go to the tire pressure / location info. If you see " -- ", then the system cannot read the tires. Tech JK
