This can typically be done by locating the TPMS reset button, holding it until the light blinks three times, and then starting the vehicle to allow the system to refresh. If the light continues to flash, it may indicate a problem with the TPMS sensors or their batteries, which would require further inspection. In such cases, consulting the owner's manual for specific tire pressure guidelines and troubleshooting tips is advisable. If the warning persists despite following these steps, it may be necessary to seek assistance from a certified Acura dealership to diagnose any underlying issues, ensuring your vehicle remains safe and performs optimally.

In some instances, the TPMS may need to be reset, a process that can typically be performed by following the specific instructions in your vehicle's manual.
