Press the trip odometer button to advance to the next menu. Trip Distances: This menu shows the distances that the vehicle has driven between specific points. The trip odometer will record the number of miles up to 9,999.9 miles or 9 999.9 km travelled for up to two trips. When 9,999.9 miles or 9 999.9 km is reached for either trip, the odometer for that trip will go back to zero. 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 kilometers, access the trip to reset and press the set/reset button. 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 or kilometers driven since the ignition was last turned on. This can be used if the trip odometer was 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 began moving. Once the vehicle has begun moving, the trip odometer will accumulate mileage. For example, if the vehicle was driven 5.0 miles (8.0 km) before the vehicle 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 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. Press the trip odometer button again to access the odometer. Set/Reset r (Set/Reset): Press this button to set or reset a menu item when using the trip odometer or options buttons. 3-50
