Engine Light and Airbag light is on

I have a 1995 previa with s/c engine with 150000 miles. The engine light is always on and the light of airbag will turn on a few seconds when I start the engine. Does anyone know the reason? I can drive the car normally. Should I get it check? I did before but the engine light turn on a again just a few days later.

Thank you for answering...

if your engine light is on, it means that there is a code stored. you should buy a Haynes manual and follow the procedure to how check the code to find out what it is. 20 dls well spent. keep us posted. good luck.
