If you need to reset and turn off a tire pressure warning light, you'll usually need to manually press a TPMS (tire pressure monitoring system) reset button. In most cars, it can be found somewhere underneath the steering wheel and around the steering column. This button might show a symbol akin to tire treads on the ground, with a circle in the middle, and two arrows pointing at it from either side. Plus, this button might also show a large SET text to indicate its purpose - doing a hard reset on the TPMS sensor. It's wise to check the owner's manual to properly determine the exact location of the TPMS reset button, though. In some cars, this button might be located elsewhere, usually somewhere hidden and somewhat out of sight.
