■Hybrid battery (traction battery) status
●The display changes in 8 levels according to the remaining charge amount
of the hybrid battery (traction battery).
●The hybrid battery (traction battery) status is also displayed on the following
screen, but the contents of the display are the same.
• Sub-screen of the main display (P. 125)
• Hybrid System Indicator (P. 132)
• Head-up display (if equipped) (P. 161)
●The charge amount of the hybrid battery (traction battery) is automatically
controlled by the hybrid system. For this reason, even if electricity is recov-
ered via the 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 mal-
function.
■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.Low

■Enabling/disabling of the head-up display
When the head-up display is turned off with the “HUD” switch, it is not dis-
played until the “HUD” switch is used to turn the head-up display on again.
(Operation of the head-up display is not linked with the power switch.)
■ Display brightness
● The brightness of the head-up display is automatically adjusted according to
the operation status of the headlights (on/off) and the brightness of the sur-
roundings.
● When the brightness of the head-up display is adjusted to a certain level or
higher, the display automatically dims when the vehicle is stopped. Once the
vehicle starts off and the vehicle speed reaches approximately 5 km/h
(3.1 mph) or more, the display automatically returns to its previous bright-
ness.
■ Vehicle speed display
In extremely cold environments, the display of the speedometer and the vehi-
cle speed of the head-up display may slightly differ.
■ Head-up display
The head-up display may seem dark and hard to see when viewed through
sunglasses, especially polarized sunglasses.
■ When the 12-volt battery is disconnected
The customize settings of the head-up display will be reset.
WARNING
■ Before using the head-up display
● Check that the position and brightness of the head-up display image does
not interfere with safe driving. Incorrect adjustment of the image’s position
or brightness may obstruct the driver’s view and lead to an accident,
resulting in death or serious injury.
● Do not continuously look at the head-up display while driving as you may
fail to see pedestrians, objects on the road, etc. ahead of the vehicle.
