* Check Engine Light: You can't simply reset this with a switch. The light illuminates because the onboard computer has detected a problem. You'll need to diagnose and fix the underlying issue. A code reader can help identify the problem. *Disconnecting the battery for a short time might clear the light, but the problem will likely return unless fixed.*
* Other warning lights: Similar to the check engine light, other warning lights (like the ABS or oil pressure light) indicate a problem that needs to be addressed, not just a switch reset.
* Power windows or locks: These systems sometimes have issues that might seem like they need a "reset," but usually, it's a fuse, a faulty switch, or a wiring problem. Checking fuses is the first step.
* Trip odometer: This often has a button on the instrument cluster itself, near the speedometer, to reset it.
