A maintenance time notification device includes a storing unit storing a threshold value of a usage time or a traveling distance for each of a plurality of vehicle parts; a measuring unit measuring the usage time and the traveling distance of a vehicle since the vehicle began to be used for each of the vehicle parts; a maintenance period determination unit determining a maintenance period of each of the vehicle parts by comparing the usage time and the traveling distance measured by the measuring unit, with the threshold value; and a reporting unit reporting to a passenger based on a determination result of the maintenance period determination unit.

A vehicle meter unit has a control unit and a controller area network (CAN) constituting a communications network. On-vehicle systems such as an engine control system, anti-lock braking system and electric power steering system are also provided with CANs and fault diagnostic functions for decentralized control. Faults in the systems are displayed in fault codes through the control unit on a liquid crystal display on which the indications of an odometer and trip recorder are displayed.

In a system for warning a failure to wear a seat belt to urge a vehicle operator to wear the seat belt, a sound emitter is activated when a vehicle speed is higher than a threshold level and the seat belt is not fastened. The sound emitter cyclically alternates between a sound emitting state and a silent state when activated, the silent state lasting for a period of at least three seconds each time. Because the silent state is interposed between sound emitting states and because the warning is not emitted when traveling for a short period of time at a low speed, for instance, in a parking garage or the like or when the vehicle is stationary, the annoyance to the vehicle operator is minimized while allowing the vehicle operator to be kept warned.
