There's no physical "reset" button for the tire pressure monitoring system (TPMS) on a Dodge Caliber. The system automatically resets itself after the tires are inflated to the correct pressure and the vehicle is driven for a short distance (usually around 10-20 miles). The light should then turn off.
If the light remains on even after properly inflating your tires and driving, there might be a problem with a sensor or the system itself. You should consult your owner's manual for more specific instructions or visit a tire shop or Dodge dealership for diagnosis and repair.
