Radiator light showing up on dashboard

1996 S420

Trying to open the hood and the glove box to get the manual

Hi .
When the radiator warning light comes on this is to warn you the coolant level is getting low.
When engine is cold check the coolant level and top off if needed.
If level is good then you will have a possible problem with a short in the circuit or the level sensor is bad and needs replacing.Need further assistance with this issue then please get back to me.
Even after accepting you can get back to me anytime without any extra cost.
