2000 Cadillac SLS

Need more specifics. What are the messages, and how are they determined to be incorrect?

For one, a faulty coolant level sensor, which is part of the reservoir, could be at fault for the check coolant message. Is the engine getting hot, how has it been determined it is not, by the gauge? When it shows traction engaged, is there any noise like ABS activation, or a feeling of torque reduction at the time. When do the seats adjust and readjust, during remote pressings or ignition key insertion? I don't think that these messages can be presumed false, They are relatively unrelated, and not too uncommon. Other than the seats adjusting and readjusting.

You can disconnect the coolant level sensor, it is on the bottom of the reservoir. If you no longer have a message, that is what is turning IT on. Is this coolant level message intermittent in nature, or always on? The traction message, if it is traction engaged(or active), may be inadvertent. The best thing to do would be to enter diagnostics by pressing info up, and on/off. After the segment check, it will display ALL, press on/off again, it will display ALL CODES, and press on/off again. Have a writing utensil, and a piece of paper and record all codes. If there are no codes relevant to your symptoms, I may not be of much help over the net. It would require more of a hands on approach to diagnosis.
