When a vehicle is determined to be traveling on a rough road, wherein increased air consumption is expected by vehicle components, a warning threshold that triggers an alert regarding excessive air consumption is increased. A duty cycle for an on-board air compressor is also increased to a level just below the increased warning threshold. In this manner, the air compressor duty cycle can be increased to meet the increased air pressure demand caused by the rough road conditions without triggering false positive alerts or distracting the driver.
