    CHECK ILLUMINATION CONTROLLED BY RHEOSTAT SWITCH


    1. Perform the following and check that the illumination controlled by the rheostat switch illuminates properly.


      1. If the vehicle is in a bright area, move it to a dark area.

        Tip:

        When the vehicle is in a bright area, the switch illumination may not turn on due to the auto dimmer function.
