CALIBRATION

The system normally takes 15 to 20 minutes of driving in each of three speed ranges to "learn" tire pressures. The speed ranges are: 15 to 40 mph, 40 to 65 mpg, and above 65 mph. When learning is complete, the system will alert you after 2-8 minutes if a tire is 12 psi different from the other three tires. Detection thresholds may be higher and detection times longer on rough roads, curves and high speeds. The system is not capable of detection at speeds greater than 75 mph.
