Energy information display
Symptom Possible cause Possible solution
The instant value shown on the energy economy
information continues to show the maximum value. This is due to power stored by the cooperative
regenerative brake being used. Battery power is stored by the cooperative regenerative
brake while driving. While this occurs, the instant value
will be displayed as the maximum. The maximum value
will be displayed until the regenerated power is
consumed.
The driving range increase/decrease when the air
conditioner/heater is ON/OFF that is displayed in the
energy usage information screen is displayed as +0
mile (+0 km) or -0 mile (-0 km). The power used for the air conditioner/heater will
decrease in response to the power used by the traction
motor and the increase/decrease difference of the
driving range will be under ±1 mile (±1 km). Also, when
the Li-ion battery available charge is low, the increase/
decrease of the driving range will also become smaller. This is not a malfunction.
