PROBLEM TO BE SOLVED: To enable a user to properly maintain the tire inflation pressure according to the condition. SOLUTION: A main control part 107 displays an alarm sentence on a display device 6 via a GUI control part 108 when respective tire inflation pressures are below a first normal inflation pressure condition. When a highway is included in the guided path even though conforming to the first normal inflation pressure condition, this control part investigates if the respective tire inflation pressures conform to a second normal inflation pressure condition or not, and when they do not conform to the second normal inflation pressure, an alarm sentence is displayed. The second normal inflation pressure condition is for defining the normal tire inflation pressure condition more strictly than the first normal inflation pressure condition. COPYRIGHT: (C)2004,JPO |
