Where is the %$#@!! odometer trip reset switch?
The instructions are in your owner’s manual. If you don’t have an owner’s manual, you may want to consider purchasing one. It’s chock full of handy information about your car. For the benefit of the owner’s manual impaired, on the late-model cars “The trip odometer in the lower part of the speedometer can be turned back to zero by pressing the reset-button, located in the left section of the center dashboard vent. The ignition must be on.” It looks like a half-sized vent air direction slider. On the early cars, odometer is mechanical, and the trip reset button is right near the trip odometer.
