Trip/Fuel Menu Items
3 (Trip/Fuel): Press this button to scroll through the
following menu items:
Odometer
Press the trip/fuel button until ODOMETER displays.
This display shows the distance the vehicle has
been driven in either miles (mi) or kilometers (km).
Trip A and Trip B
Press the trip/fuel button until TRIP A or TRIP B
displays. This display shows the current distance
traveled in either miles (mi) or kilometers (km) since the
last reset for each trip odometer. Both trip odometers
can be used at the same time.
Each trip odometer can be reset to zero separately by
pressing the set/reset button while the desired trip
odometer is displayed.
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 four seconds. The trip
odometer will display the number of miles (mi) or
kilometers (km) 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 miles (8 km)
before it is started again, and then the retro-active reset
feature is activated, the display will show 5 miles (8 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 (mi) or
kilometers (km) that were driven during the last
ignition cycle.
