■The meters and display illuminate when
The power switch is in ON mode.
■Instrument panel brightness adjustment
The instrument panel brightness levels when the tail lights are on and off can be
adjusted individually. However, when the surroundings are bright (daytime, etc.),
turning on the tail lights will not change the instrument panel brightness. At this time,
any adjustments made to the instrument panel brightness levels will be applied to
both settings at once.
■Limitation of brightness adjustment
The brightness of the instrument panel lights is automatically adjusted based on the
light sensor detecting how bright the surroundings are. However, if the instrument
panel brightness has been manually set to either the brightest or darkest setting, the
automatic adjustment will not be performed.
■Hybrid System Indicator
●Hybrid System Indicator is displayed when the driving mode is other than the sport
mode.
●By keeping the indicator needle within Eco area, more Eco-friendly driving can be
achieved.
●Charge area indicates regeneration* status. Regenerated energy will be used to
charge the battery.
*: When used in this manual, “regeneration” refers to the conversion of energy cre-
ated by the movement of the vehicle into electrical energy. Charge area
Shows regenerative charging.
Hybrid Eco area
Shows that gasoline engine power is not
being used very often.
The gasoline engine will automatically stop
and restart under various conditions.
Eco area
Shows that the vehicle is being driven in an
Eco-friendly manner.
Po w e r a r e a
Shows that an Eco-friendly driving range is
being exceeded (during full power driving
etc.)

■ECO lamp and SPORT lamp
●When sport mode is selected, SPORT lamp (red) will illuminate.
●When all of the following conditions are satisfied and Eco-friendly driving, ECO
lamp (blue) will illuminate. (ECO lamp will become brighter the more Eco-friendly
driving you perform. Also, while the vehicle is stopped or the acceleration exceeds
Zone of Eco driving, ECO lamp turns off. (→P. 92) However, when Eco drive
mode is selected, while the vehicle is stopped or the acceleration exceeds Zone of
Eco driving, ECO lamp does not turn off.):
• Driving with the shift lever in D
• Paddle shift switch is not operated.
• Either normal mode or Eco drive mode is selected.
• The vehicle speed is approximately 80 mph (130 km/h) or below.
■Tachometer
Hybrid System Indicator switches to the tachometer when driving mode is in sport
mode.
■Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help improve
fuel efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may differ even when vehi-
cle operation and driving conditions are the same.
■Customization
Settings (e.g. on/off operation of ECO lamp) can be changed.
(Customizable features →P. 807)
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indi-
cates the maximum engine speed.
●The engine may be overheating if the engine coolant temperature gauge is in the
red zone (H). In this case, immediately stop the vehicle in a safe place, and check
the engine after it has cooled completely. ( →P. 7 74 )

■System check display
After turning the power switch to ON mode, “SYSTEM CHECK” is displayed while
system operation is checked.
■Outside temperature display
In the following situations, the correct outside temperature may not be displayed, or
the display may take longer than normal to change.
●When stopped, or driving at low speeds (less than 12 mph [20 km/h])
●When the outside temperature has changed suddenly (at the entrance/exit of a
garage, tunnel, etc.)
■Setting display automatic cancelation
In the following situations, setting display in which the settings can be changed
through the “DISP” button will automatically be turned off.
●When a warning message appears while the setting display is displayed
●When the vehicle begins to move while the setting display is displayed
■Tire inflation pressure (if equipped)
●It may take a few minutes to display the tire inflation pressure after the power switch
is turned to ON mode. It may also take a few minutes to display the tire inflation
pressure after inflation pressure has been adjusted.
●“---” may be displayed if the tire information cannot be determined due to unfavor-
able radio wave conditions.
●Tire inflation pressure changes with temperature. The displayed values may also be
different from the values measured using a tire pressure gauge.
■Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is character-
istic of liquid crystal displays, and there is no problem continuing to use the display.
■Customization
Setting of available languages can be changed. (Customizable features →P. 807)

CAUTION
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion display. At extremely low temperatures, the information display monitor may
respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear number
appearing on the display. This lag could cause the driver to downshift again, caus-
ing rapid and excessive engine braking and possibly an accident resulting in death
or injury.
■Cautions during setting up the display
As the hybrid system needs to be operating during setting up the display, ensure
that the vehicle is parked in a place with adequate ventilation. In a closed area such
as a garage, exhaust gases including harmful carbon monoxide (CO) may collect
and enter the vehicle. This may lead to death or a serious health hazard.
NOTICE
■During setting up the display
To prevent 12-volt battery discharge, ensure that the hybrid system is operating
while setting up the display features.
