When stopping the hybrid system
From the time the hybrid system is started until it is turned off, the driving time, distance traveled, average fuel consumption, and Eco score result are displayed on the multi-information display approximately every 30 seconds.

• Driving time since the hybrid system started
• Distance traveled since the hybrid system started
• Average fuel consumption after the hybrid system started
• Eco score result and advice
• Score display for each Eco score item

Warning lights and indicators
The warning lights and indicators inform the driver of the status of the vehicle’s various systems. For the purpose of explanation, the following illustration displays all indicators and warning lights illuminated.

Main display

The main display shows basic information, such as the vehicle speed and remaining fuel amount. Also, the displayed information can be switched according to user preference.

Display contents (vehicles without RSA [Road Sign Assist])

1. Speedometer: Displays the vehicle’s speed
2. Fuel gauge: Displays the quantity of fuel remaining in the tank
3. Outside temperature: Displays the outside temperature within the range of -40°F (-40°C) to 122°F (50°C). The temperature display flashes for approximately 10 seconds when the outside temperature drops to approximately 37°F (3°C) or less, and then stops flashing.
4. Mileage display (odometer/trip meters/driving range): The possible driving range estimated from the mileage and current remaining fuel amount can be displayed.
5. Average fuel consumption display: The average fuel consumption that is linked with the contents of the mileage display can be displayed.
6. Sub-screen: When the split screen is selected for the main display, information such as the Hybrid System Indicator and current fuel consumption can be displayed.

Energy monitor
The energy monitor can be used to check the vehicle drive status, hybrid system operation status and energy regeneration status.
When energy is flowing, an arrow appears and a bright point of light moves to show the direction of the flow of energy. When energy is not flowing, the bright point of light is not displayed.

1. Gasoline engine
2. Electric motor (traction motor)
3. Hybrid battery (traction battery)
4. Tire
5. The bright point of light shows the flow of energy

Hybrid battery (traction battery) status

1. The display changes in 8 levels according to the remaining charge amount of the hybrid battery (traction battery).
   1. The hybrid battery (traction battery) status is also displayed on the following screen, but the contents of the display are the same.
   2. Sub-screen of the main display
   3. Hybrid System Indicator
   4. Head-up display (if equipped)
2. The charge amount of the hybrid battery (traction battery) is automatically controlled by the hybrid system. For this reason, even if electricity is recovered via regenerative braking, or electricity is generated via the gasoline engine, the displayed hybrid battery (traction battery) charge amount may not reach the highest level (level 8). However, this does not indicate a malfunction.

Remaining charge amount warning of hybrid battery (traction battery)

1. 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 continuously.
2. 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.

Hybrid System Indicator
The display changes according to accelerator pedal operation and displays the current driving status and energy regeneration status. The Hybrid System Indicator can be displayed on the sub-screen of the main display and the head-up display (if equipped)
