Tire pressure monitoring system is referred to as TPMS. The TPMS reset button is often located below the steering wheel. Your car’s TPMS needs to be electronically reset after you replace the tires in order to erase the error message. Hold the TPMS reset button down until the tire pressure light blinks three times, then let go of the button to complete the process. Your car should be started, and the sensor will refresh after 20 minutes.

How can I make my low tire pressure warning light come on?
How to Clear the Tire Pressure Indicator
- Don’t start the car; just turn the key to “on.”
- While the car is off, disconnect the positive battery cable.
- All tires, including the spare, should be 3 PSI overinflated before being entirely deflated.
- Bring your car to our service department for qualified help.
Why won’t my tire pressure warning light turn on?
Try the following if your TPMS light is still on after you have inflated your tires to the recommended pressure: 10 minutes at a speed of 50 mph would be plenty. When you start the car again, the TPMS light ought to be off because this ought to reset the tire sensors.
Why, after filling the tires, is the tire pressure light still on?
If you’ve inflated your tires, but the air pressure warning light continues to flash, your tire pressure monitoring system is malfunctioning or you have a gradual leak. A bright TPMS warning light indicates a problem with a tire pressure sensor, assuming there isn’t a leak in your tire. One of them might be damaged, the lithium-ion battery might be dead, or the TPMS itself might have an internal problem. You’ll need to get your Tire Pressure Monitoring System repaired in any of these scenarios.
Quick Tip: Recheck the tire to ensure it is inflated to the correct air pressure if the TPMS warning light illuminates again after you have inflated it. Low tire pressure indicates an air leak, which requires repair or tire replacement.
Should the TPMS be reset after purchasing new tires?
After changing or rotating your tires, or after adding new sensors, you should always reset your TPMS. Even after you have inflated your tires, some sensor manufacturers advise restarting the device. By teaching the primary TPMS system to identify the sensors in their new locations, resetting the TPMS is frequently referred to as retraining the system. TPMS reset procedures vary from vehicle to vehicle and typically involve a specific sequence of ignition and pedal actions, a configuration change in your dashboard menu, or the use of a TPMS Reset Tool.
In what location is the TPMS sensor?
In the US, direct TPMS usage is more prevalent. The sensors are either housed in the tire pressure valve, which also serves as an antenna, or they are band-clamped to the wheel rim. These gadgets deliver the data to an on-board computer.
How is a service tire monitor cleared?
It must be stressful to assume your tire pressure is low all the time! Fortunately, there are quick fixes for service tire monitor systems.
Resetting the system is the simplest technique to repair the service tire monitor system in your car. When the sensors occasionally need extra assistance, there are two ways to reset the system.
Driving for at least 10 minutes at highway speeds is the first step towards resetting the system. When you start the car again or after your current drive, the light ought to go off.
You should reset the TPMS light if the approach described above doesn’t work. You can accomplish this by:
- without starting the engine, turning the ignition to the on position.
- Locate the TPMS button, then press and hold it until the alert flashes or goes away.
- driving around for a while, stopping, and then starting the car again.
The service tire monitor system should be maintained by a qualified technician if neither of the aforementioned approaches succeeds.

How soon does the tire pressure warning light turn on?
After a few kilometers of driving, the light may turn off if the tires are adequately inflated. After around 10 miles, if the light still remains on, it may be necessary to reset the TPMS as instructed in the owner’s handbook of the car.
When the tire pressure light is on, can I drive?
You should be able to find our store or an air pump if the light just came on and you need to get there. However, it is unsafe to keep driving while the light is on. This is why: When you drive your car with low tire pressure, you accelerate the premature and severe tire wear.
Can I drive for how long with the tire pressure light on?
Low tire pressure warnings shouldn’t be used while driving for extremely long or very far. If you must, take into account how the allowed distance fluctuates under the various circumstances listed below.
Offroad
If you must, don’t drive off-road with low tire pressure for more than 10 minutes or 10 miles. Low pressure while off-roading could leave you stranded in the woods.
On Snow/winter
In any case, when there is snow on the ground, tires suffer harder. Low tire pressure makes the situation worse because it is more difficult to gain traction and roll ahead. Under these circumstances, you should avoid driving with low tire pressure for more than 40 miles or for more than 30 minutes.
In Summer
Summer brings additional heat while also bringing an end to snowfall. Driving on low tire pressure in the summer requires going extremely slowly and limiting your driving time to no more than 30 minutes. Otherwise, you run the danger of overheating and blowing out a tire.
Does Lexus alert you to a low tire?
Your Lexus comes with a built-in tire pressure warning system that alerts you when one or more tires are under the manufacturer’s specified PSI. You can fill your car’s tires in this way to prevent future problems.
What occurs if TPMS sensors are not replaced?
Customers who ask you to turn off their TPMS light just and leave the underlying problem unattended can put you and your business at unnecessary risk. You are breaking the NHTSA’s “make inoperative provision” if you switch off the light without resolving the problem, which makes shops liable for deactivating the TPMS. It is your duty to let the customer know this and to decline service if they don’t want the problem handled properly.
It is strongly advised to replace all sensors at once if a single sensor has reached the end of its useful life. When one sensor fails, the others are likely to follow suit quickly, just like with headlights. The same holds true for replacing an impact sensor or damaged valve stem. Your consumers should be aware of this since it will assist you give their vehicle the finest care possible. They also find it convenient.
The TPMS sensors must always be reactivated and calibrated for drivers who change their tires as the seasons change. If you don’t do this, the car’s TPMS won’t function properly and could turn on the TPMS light.
How does the TPMS identify each tire?
The anti-lock brake system’s wheel speed sensors are often used by an indirect TPMS. On-board computer systems can employ these sensors to compare wheel revolution rates between individual wheels as well as to other vehicle operation data, such as speed.
The computer can determine the relative size of the tires on your car based on how quickly each wheel rotates. The computer determines that a tire is underinflated when a wheel starts spinning more quickly than normal and warns the driver accordingly.
Therefore, a device for monitoring tire pressure indirectly does not truly measure tire pressure. The same kind of measurement you may observe with a tire gauge is not being processed electronically. An indirect tire pressure monitor only counts the rotational speed of your tires and sends instructions to the computer to activate the indication light when something seems off with the rotation.
