Late model Toyota Tacoma pickup trucks are equipped with a tire pressure monitoring system (TPMS). This system is designed to alert drivers when the pressure in one or more tires falls below the recommended inflation pressure. If the system detects a problem, a warning light on the instrument panel with appear. Occasionally you will need to recalibrate this system in order to extinguish the warning light.
Step 1: Park the vehicle on level ground. Engage the parking brake. Turn off the engine.
Step 2: Check the pressure in all four tires to make sure they are inflated to the proper pressure. The proper tire pressure can be found in the vehicle’s owner’s manual and also on a sticker located on the driver’s side door frame.
