Driving range
Symptom Possible cause Possible solution
The driving range cannot be displayed. The power switch is in the "ACC" position. The driving range can be displayed when the power
switch is in the "ON" position or when the READY to
drive indicator light is on.
It cannot be displayed because the distance to empty is
too short. Charge the battery. Once the distance to empty
increased it will be displayed.
The driving range is displayed in an oval shape. As a result of the system correcting latitude and
longitude, it may not be displayed as a circle. This is not a malfunction.
The distance to empty that is displayed in the lower left
hand side of the driving range and the scale of the map
do not match. As the map is displayed in 2D, the distance to empty
may differ from the actual distance on the road. This is not a malfunction.
Drive using the numerical value on the lower left hand
side of the screen as a guide.
