I am not sure what you mean by automatically... It will be applied to OpenGL in draw phase. When used with TexGenNode it will be applied globally for whole render stage nad used for all the scene. If used as TextureStateAttribute it will be applied by lazy state update when drawables using this attribute are drawn. Small warning: If you intend to use EYE_LINEAR TexGen as a texture state attribute it won't most probably work as you expect. Its due to unpredictability of glModelView matrix which will be current when TexGen gets applied by lazy state update. Basically TexGen as texture state attribute will work in predictable way with modes that use vertex coords (not require eye coords).
