While performing these checks, inspect the tires for any visible damage such as punctures or bulges, as these can compromise safety and performance. If the warning light remains on despite your efforts, it is essential to seek professional assistance to diagnose any underlying issues with the TPMS, as neglecting these symptoms could lead to unsafe driving conditions or further damage to your vehicle.
