* Trip odometer: This is usually a button on the instrument cluster, often involving holding it down or pressing it repeatedly. Consult your owner's manual for the exact procedure.
* Check Engine Light (CEL): You can't reset a CEL simply by pressing a button. The light indicates a problem detected by the onboard diagnostic system (OBDII). You need to address the underlying issue, and *then* the light might reset itself after a certain number of driving cycles, or you might need to use an OBDII scanner to clear the code.
* Radio presets: The radio itself likely has buttons to clear presets.
* Other computer systems: Various computer modules in the vehicle might have their own reset procedures, but these typically aren't accessible via a simple button. They often require special tools or procedures.
To find the specific reset procedure you need, consult your 2002 Dodge Dakota owner's manual. It's the best resource for information specific to your vehicle.
