     The fan  141  may be configured to rotate in response to the operation of the air conditioner so that the air having heat exchanged by the air conditioner is blown into the interior of the vehicle. 
     The engine  142 , as a power device of the vehicle, may be configured to generate a driving force of the vehicle. 
     The seat resistive wire  143  may be provided in the seat  111 , may be configured to perform on or off operation in response to a control command of the processor  150 , and may be configured to apply heat to the seat  111  in an on-operation. 
     The sound outputter  144  may be configured to output a sound in response to a control command of the processor  150 . 
     The sound outputter  144  may be provided in at least one of the interior or exterior of the vehicle.

     The processor  150  may be configured to control the display  135  or the cluster  113  to display the strength of the magnetic field generated in the vicinity of the center of the steering wheel  120  or the upper body of the driver, which is a strength transmitted to the resistive wire controller  123 . With such a configuration, the driver may identify the strength of the magnetic field reaching himself/herself in real time. The processor  150  may be configured to, upon determining that the strength of the magnetic field reaching the driver is greater than or equal to the reference strength, control the display  135  or the cluster  113  to display notification information about a danger.
