1. A system for indicating warning conditions associated with certain parameters related to the operation of a vehicle, said system comprising:

  • at least one sensor for sensing a certain parameter associated with the operation of the vehicle, said sensor sensing a plurality of levels of said parameter and responsively producing a plurality of sensor signals indicative of the different levels of said parameter;

    control means coupled to said at least one sensor for receiving signals therefrom, said control means being operable to receive signals from said at least one sensor indicative of the level of said sensed parameter being equal to a predetermined level; and

    display means for displaying a warning condition associated with the sensed parameter when the level of said sensed parameter is equal to said predetermined level, said display means being operable at a first illumination level during day-time operations and at a second illumination level during night-time operations, said first illumination level being greater than said second illumination level;

    said control means being operable to display a warning condition associated with the sensed parameter on said display means when said control means receives a signal from said at least one sensor indicative of the level of said sensed parameter being equal to said predetermined level;

    said control means being further operable to increase the illumination level of said display means when a warning condition is displayed thereon and when said display means is being operated at said second illumination level.
