Your owners manual should tell how. My wifes Silverado resets the change oil message by pushing the gas pedal 3x with the key on, but not running. Something similar for the tires. Auto Zone for free check engine light diagnostics.
That's why I remote mounted my factory radio in my trunk, to access the computer easily.
The fluid levels I would think would befaulty level sensors or corroded wiring, if the levels aren't low.
You should be able to reset all messages without your factory radio.
Security and delayed lighting, etc.are impossible to access without the radio, tho.
