Where is the TPMS reset button on the Acura MDX?
The MDX does not have a single universal, easily visible TPMS reset button across all model years. In most modern MDX editions, you reset the system through the vehicle’s on‑board settings or calibration menu, rather than pressing a dedicated button. Some older trims may have a hidden or dealer-accessible reset option, but the common approach is via the instrument cluster or a menu option after the tires are properly inflated.
How TPMS reset works in the MDX
To calibrate or reset the TPMS, you generally need to ensure each tire is inflated to the spec on the door placard and then use the on‑screen TPMS calibration option (if available) or drive the vehicle to allow the system to recalibrate automatically.
Follow these typical steps if your MDX relies on the on‑screen calibration rather than a physical reset button.
- Check all tire pressures and inflate to the recommended values on the driver‑side door placard.
- Turn the ignition to ON (engine off) or start the vehicle depending on your model’s requirements.
- Access the Driver Information Menu on the instrument cluster or center display and locate the TPMS Calibration or Tire Pressure Settings.
- Select TPMS Calibration and choose Reset or Calibrate, if your system presents that option.
- If no on‑screen option exists, drive the MDX at steady highway speeds (typically 30–50 mph) for about 10–20 minutes to allow automatic recalibration.
- Verify the TPMS light is extinguished after the calibration completes.
Following these steps should clear the TPMS light once tire pressures are correct and the system has recalibrated. If the light remains on after attempting calibration, there may be a faulty sensor or a tire pressure issue that requires service.
Model-year variations
Exact location and method can vary by MDX generation. The patterns below reflect typical approaches by era; always consult your specific year’s owner’s manual for precise instructions.
- Gen 1 MDX (2001–2006): There is no widely documented, universal physical TPMS reset button in most trims; calibration is usually done via the onboard settings or automatically after tires are inflated and the vehicle is driven.
- Gen 2 MDX (2007–2013): Similar to early generations, most trims rely on the TPMS calibration option in the vehicle’s settings rather than a visible reset button.
- Gen 3 MDX (2014–2020): Calibration is typically performed through the Driver Information System (Settings > Vehicle > TPMS Calibration) with no dedicated external reset switch.
- Gen 4 MDX (2022–present): TPMS calibration is managed in the vehicle’s information display/menu; there is generally no physical reset button, and proper tire pressures plus calibration are required.
What to do if the TPMS light stays on
- Double‑check and adjust tire pressures to the recommended values on the placard.
- Inspect for a damaged sensor or a tire leak that could prevent proper readings.
- If recalibration via the on‑screen menu or driving does not extinguish the light, seek service at an Acura dealer or tire shop to test the sensors.
Summary: Across MDX generations, the TPMS reset is typically not a conspicuous physical button. Most models rely on the on‑screen TPMS calibration feature or automatic recalibration after tires are inflated to spec and the vehicle is driven. Always refer to the owner’s manual for your exact year and trim for precise steps.
