To reset the trip distances, use the following procedures: 1. Press the trip odometer button again to access TRIP A. Press the trip odometer button again to access TRIP B. To reset the trip odometer(s) back to zero miles or to zero kilometers, access the trip that needs to be reset and press the set/reset button. 2. Press the trip odometer button again to advance to the next screen. The trip odometer has a feature called the retro-active reset. This can be used to set the trip odometer to the number of miles (kilometers) driven since the ignition was last turned on. This can be used if the trip odometer is not reset at the beginning of the trip. To use the retro-active reset feature, press and hold the set/reset button for at least three seconds. The trip odometer will display the number of miles or kilometers driven since the ignition was last turned on and the vehicle was moving. Once the vehicle begins moving, the trip odometer will accumulate mileage. For example, if the vehicle was driven 5.0 miles (8.0 km) before it is started again, and then the retro-active reset feature is activated, the display will show 5.0 miles (8.0 km). As the vehicle begins moving, the display will then increase to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc. If the retro-active reset feature is activated after the vehicle is started, but before it begins moving, the display will show the number of miles or kilometers that were driven during the last ignition cycle. 193
