Toyota Corolla Tire Pressure Reset / Button
The Toyota Corolla tire pressure warning system must be initialized / reset in the following circumstances:
- When a tire has been changed.
- When the tire inflation pressure is changed.
When the tire pressure warning system is initialized / has been rest, the current tire inflation pressure is set as the benchmark pressure.
As you drive your vehicle, the tires heat up and the pressure inside increases. Ideally, tire pressures should be checked and corrected when the tires are cold. A cold tire is the same temperature as the surrounding outside (ambient) temperature. It takes approximately 3 hours for a tire to reach ambient temperature from the last time the vehicle was driven.
If it’s not possible to check / alter tire pressures when they are cold, it’s recommended to increase the pressure by an additional 4 psi (14 kPa) above the recommended cold pressure values for your Toyota Corolla.
Recommended tire pressures
The recommended tire pressures can be found on the placard located inside the driver’s door on the B-pillar. These tire pressures are based on Toyota factory fitted tires of a specific size and rating.
Toyota Corolla Tire Pressure Reset / Button
The following procedure explains how to reset the Toyota Corolla tire pressure monitoring system:
- Park the vehicle and switch off the engine. Initialization / reset cannot be performed while the vehicle is moving. On some versions of Corolla, ensure the ignition key is turned to the ACC or LOCK position.
- Adjust the tire inflation pressure to the recommended cold tire inflation pressure level found on the pressure placard.
- For versions of the Corolla without a smart key system, turn the ignition key to the ON position and for versions of the Corolla with a smart key system, press the engine start/stop button for IGNITION ON mode.
- On certain models of the Toyota Corolla, the tire pressure reset button is located directly on the dashboard. On other models, it’s located in the glove box. Locate the tire pressure reset button and press and hold until the tire pressure warning light flashes slowly 3 times.
- For versions of the Corolla without a smart key system:
- Wait for a few minutes with the engine switch in the ON position and then turn the engine switch to the ACC or LOCK position.
- For versions of the Corolla with a smart key system:
- Wait for a few minutes with the engine start/stop button in IGNITION ON mode and then turn the engine button to off.
- Your Toyota Corolla tire pressure monitoring system is now reset and the system will use these stored tire pressure values as a reference for loss of pressure warnings.
