how do I reset the tachometer in a 2006 Chevy HHR?
Reset it? Are you asking how to reset the Trip odometer? The Tachometer measures the rpm of the engine. ex. idle speed is around 700rpm.
If it's the same as an '08 model, there's a button on the left side of the steering wheel that says "info". Keep pushing it until the trip odometer comes up. Then push the button with the funny looking arrow on it. That'll reset it. HTH. - Jim
