■The meters and display illuminate when
The engine switch is in IGNITION 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 th e 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 ligh ts 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 ei ther the brightest or darkest setting, the
automatic adjustment will not be performed.
■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 acceleration exceeds Zone of Eco driving,
ECO lamp turns off. [P. 90] However, when Eco drive mode is selected, while
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.
■Customization
Settings (e.g. on/off operatio n of ECO lamp) can be changed.
(Customizable features: P. 7 9 3 )
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. 76 1 )

■Tire inflation pressure (if equipped)
●It may take a few minutes to display the tire inflation pressure after the engine
switch is turned to IGNITION 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 th e 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. (Custo mizable features: P. 7 9 3 )
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 dr iver’s shifting and the new gear number
appearing on the display. This lag could ca use 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 engine needs to be running 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 battery discharge, ensure that the engine is running while setting up the
display features.

interfere with safe driving. Incorrect adjustment of the image’s position or bright-
ness may obstruct the driver’s view and lead to an accident, resulting in death or
serious injury.
