Welcome Hilux Surf

I have a similar experience having purchased a 94 Surf Limited Turbo Diesel - immaculate - but as they are not imported into South Africa coming by a workshop / owners manaul is a problem for me. It would be great if such a document was available electronically!

As far as the red (orange on mine) and green lights I think that the green indicates that the turbo is running while the orange acts as an ignition light. They both come on with the ignition switch and then turn off when it runs.

Good luck.
