■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 hybrid 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. 217)
• 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. 94)
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. 110)
●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. 94) 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.

●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.

■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 19 mph (30 km/h).
●In addition to the vehicle driving status, the Eco score also evaluates the air
conditioning system usage condition (P. 243). The score displayed when
the hybrid system stops is the total result of the driving status after the
<004b005c00450055004c004700030056005c00560057004800500003005600570044005500570056000300440051004700030057004b004800030044004c005500030046005200510047004c0057004c00520051004c0051004a0003005800560044004a00

■“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.
■Predictive Efficient Drive (Predictive Deceleration Support)
(vehicles with 11.6-inch display)
When a predictive deceleration support point registered in the navigation sys-
tem is approached, the system turns off the Eco accelerator guide and
informs the driver of releasing the accelerator pedal early.
For details about Predictive Efficient Drive (Predictive Deceleration Support),
refer to “NAVIGATION SYSTEM OWNER’S MANUAL”.

◆“Fuel Consumption Record”
When the unit is set to “MPH”
The transitions of the average fuel consumption after the hybrid
system starts can be checked in units of 1 mile (1.6 km) or 5 miles
(8 km) of driving.
When the unit is set to “km/h”
The transitions of the average fuel consumption after the hybrid
system starts can be checked in units of 1 km (0.6 mile) or 5 km
(3.1 miles) of driving.
■How to read the screen
The “ 1 miles” display is shown as an example. However, the
basic method for how to read the screen is the same for each fuel
consumption history screen.

When the unit is set to “MPH”:
When the recorded unit is
exceeded (every 1 mile [1.6 km]
or 5 miles [8 km] the currently
displayed history moves

est record is deleted.
When the unit is set to “km/h”:
When the recorded unit is exceeded (every 1 km [0.6 mile] or 5 km [3.1
miles]) the currently displayed history moves towards the left side and
the oldest record is deleted.
