Pajero-io -GDi Indicator light

I have a 1998 Pajero IO. The GDi indicator light (GDi ECO) does not work. When starting the jeep, all the lights excluding the GDi ECO get illuminated. I have tried driving at diffent speeds, still it does not get illuminated.

Any one has this prob? and suggestions pls.

cheers,
