My 91 350SDL was purchased without the owners manual. i've got a warning light coming on that i dont know what it is trying to tell me. it's to the left of the steering column, to the right of the outside temp readout, in between washer fluid indicator and the ABS indicator. looks like the sun with an exclamation point in the middle. dealer thinks it is a lamp out warning light. is he correct?

thanks
