Trip Odometer
WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
Trip odometer readings are calculated by the IPC based on the odometer reading received through a class 2 message from the BCM. The trip odometer is shown when selected with the odometer trip reset stem. To reset the trip odometer, press and hold the trip reset stem for about two seconds, until the trip odometer shows zero.
