Toyota retailer or Toyota authorized repairer, or any reliable repairer imme-
diately if this occurs.

■Remaining charge amount warning of hybrid battery (traction battery)
●The buzzer sounds intermittently when the hybrid battery (traction battery)
remains without charging while the shift position is in N, or the remaining
charge amount drops below a certain level.
If the remaining charge amount drops further, the buzzer sounds continu-
ously.
●When a warning message is shown on the multi-information display and the
buzzer sounds, follow the instructions displayed on the screen to perform
troubleshooting.
■About the Eco score
●After starting off, Eco score display does not start until the vehicle speed
exceeds approximately 30 km/h (19 mph).
●In addition to the vehicle driving status, the Eco score also evaluates the air
conditioning system usage condition (P. 254). The score displayed when
the hybrid system stops is the total result of the driving status after the
hybrid system starts and the air conditioning usage condition.
■“EV Energy” and “EV Distance” display
The rate at which the “EV Energy” and “EV Distance” remaining amount
decreases depends on the driving conditions of the vehicle. Also, the “EV
Energy” and “EV Distance” remaining amount may decrease due to system
power consumption even though the vehicle is not being driven.
