■When operation of each function stops
● The Hybrid System Indicator stops operating in the following situations.
• The “READY” indicator is not illuminated.
• The shift position is not D or B.
● The Eco score and “ECO Accelerator Guidance” stop operating in the fol-
lowing situations.
• The Hybrid System Indicator is not operating.
• Dynamic radar cruise control with full-speed range is being used.
■ Display of the remaining hybr id battery (traction battery)
● The current amount of the remaining hybrid battery (traction battery) is dis-
played in the Hybrid System Indicator or the sub-screen on the main display.
(→P. 202)
• The remaining battery for EV driving in EV mode is displayed in green, and the remaining battery used in HV mode is displayed in blue.
• The amount of the remaining battery displayed decrease as the vehicle is
driven and increase when the hybrid battery (traction battery) is charged,
electrical energy is regenerated using the regenerative braking (→P. 86)
or electricity is generated by the gasoline engine.
• If the remaining battery is not displayed in green, HV mode is automati- cally selected and EV mode cannot be used. To enable EV driving,
charge the hybrid battery (traction battery). ( →P. 102)
● The amount of the hybrid battery (traction battery) in HV mode is automati-
cally controlled by the hybrid system. The amount of remaining hybrid battery
(traction battery) in HV mode may not reach the top line
* even if electrical
energy is regenerated using the regenerative braking ( →P. 86) or electricity
is generated by the gasoline engine. However, this does not indicate a mal-
function. Also, even if the display of the remaining hybrid battery (traction
battery) exceeds the top line, the display is shown in blue until the vehicle
returns to EV mode.
*: The position of the boundary line between EV mode and HV mode on the
display of the remaining hybrid battery (traction battery).
● Depending on the charging situation, when the display of the remaining
hybrid battery (traction battery) is shown during charging, charging contin-
ues even after the display of the remaining hybrid battery (traction battery)
shows a fully charged state. However, this does not indicate a malfunction.
Please wait until charging is finished. The hybrid battery (traction battery)
is fully charged
The hybrid battery (traction battery)
for EV mode is not remaining

4-1. Key information
■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
● If the battery becomes low, an alarm will sound in the cabin and a message
will be displayed on the multi-information display when the hybrid system
stops.
● As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. ( →P. 627)
• The smart key system or the wireless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
You can replace the battery by yourself ( →P. 627). However, as there is a
danger that the electronic key may be damaged, it is recommended that
replacement is carried out by your Toyota dealer.
● To avoid serious deterioration, do not leave the electronic key within 3 ft.
(1 m) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Table lamps
• Induction cookers
