How do you reset the tire pressure sensor on a Lexus?
To reset the tire pressure monitoring system (TPMS) on a Lexus, you typically inflate all tires to the recommended cold pressures and then either drive to trigger an automatic relearn or use a manual reset option found in the vehicle’s settings or a dedicated TPMS button. The exact method varies by model year and trim.
Understanding TPMS and when to reset
TPMS warns you when a tire is underinflated or overinflated. A reset is usually needed after inflating tires, rotating wheels, or replacing tires to ensure the system accurately tracks current pressures. Some Lexus models relearn automatically after you bring all tires to the correct pressures and drive for a short period, while others offer a manual reset option.
Automatic relearn by driving
How the automatic relearn works
Many modern Lexus models will relearn the new tire pressures without a dedicated button. After you’ve inflated all tires to the specified cold pressures, you can drive the car to allow the system to relearn the sensors. Here are the typical steps people follow.
- Inflate all tires to the recommended cold pressures listed on the door jamb sticker or in the owner's manual. Include the spare only if your model monitors it.
- Turn the ignition to the ON position without starting the engine (or start the car if required by your model). Ensure you follow your owner's manual for ignition specifics.
- Drive on a clear, level highway at a steady speed—roughly 50–60 mph (80–97 km/h)—for about 10–20 minutes to initiate the relearn process.
- Observe the TPMS light on the instrument cluster. If the system has relearned, the warning light should go out. If it stays illuminated, proceed with the manual reset alternative or seek service.
In many cases, the light will extinguish after a successful automatic relearn. If it does not, consider the manual reset method or a professional check for sensor or leak issues.
Manual reset or calibration via settings
Where to look for reset options
Some Lexus models provide a manual TPMS reset or calibration through the vehicle’s settings. The exact location can vary by year and trim, so consult the owner's manual for model-specific instructions. If your model supports it, the reset can be accomplished with a dedicated button or through the infotainment/vehicle settings menu.
General steps you may encounter are outlined below. The process may differ on your specific model, so use this as a guide and verify with the manual.
- Inflate all tires to the recommended cold pressures.
- With the ignition in ON and the engine off (or as specified by your model), locate the TPMS reset button. Common locations include a small recessed button under the dashboard near the steering column, on the center console, or inside the glove box. It may be labeled “RESET” or bear a TPMS symbol.
- Press and hold the button until the TPMS indicator on the dash blinks or a confirmation message appears.
- Release the button and drive for 10–20 minutes at a steady pace to complete the relearn.
Not all Lexus models include a visible reset button or a dedicated menu item. If you cannot locate a reset option, review the specific owner's manual for your year/model or contact a Lexus service center for guidance.
Troubleshooting: what to do if the warning light stays on
If the TPMS warning light remains on after attempting a reset, investigate potential causes such as underinflation, a damaged sensor, a weak sensor battery, or a slow leak. Consider the following steps:
- Recheck tire pressures with a reliable gauge and re-inflate to the recommended levels.
- Inspect tires for punctures, leaks, or damaged valve stems.
- Consider replacing TPMS sensor batteries in older vehicles or replacing faulty sensors if needed.
- Visit a tire shop or Lexus service center to reprogram or replace sensors and perform a proper relearn.
Persistent TPMS warnings usually warrant professional inspection to diagnose sensor faults or leaks.
Summary
Resetting a Lexus TPMS typically involves two pathways: automatic relearn by driving after bringing all tires to the correct pressures, or a manual reset/calibration via a button or Settings menu. Since procedures vary by model and year, consult your owner’s manual for model-specific steps. Regularly checking tire pressures and monitoring the TPMS indicator helps maintain safety and fuel efficiency.
