What you might be referring to is resetting the trip odometer. There are usually two odometers:
* Total Odometer: This shows the total mileage the vehicle has accumulated since it was manufactured. This cannot be reset.
* Trip Odometer(s): These show the mileage driven since the last reset. Most Grand Caravans have at least one trip odometer, and some might have two.
To reset the trip odometer on a Dodge Grand Caravan, the method varies slightly depending on the model year. However, it typically involves pressing and holding a button on the instrument cluster, usually located near the speedometer or odometer display. Look for a small button labeled "TRIP" or something similar. You might need to hold it for a few seconds until the numbers reset to zero.
If you're unsure how to reset your specific Grand Caravan's trip odometer, consult your owner's manual. This is the best resource for accurate instructions tailored to your vehicle's year and model.
