Shift into neutral and set the parking
brake.
(Automatic transaxle)
Shift the selector lever to the P
position and set the parking brake.

information such as after first
purchasing your vehicle or the
information is deleted when the battery
cables are disconnected, the actual
distance-to empty/range may differ from
the amount indicated.
Average fuel economy mode
This mode displays the average fuel
economy by calculating the total fuel
