■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 the inst rument panel brightness. At th is time, any adjustments made
to the instrument panel brightness levels will be applied to both settings at once.
■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.)
●When “_ _”or “E” is displayed, the system may be malfunctioning.
Take your vehicle to your Lexus dealer.
■Pop-up display
●In some situations, such as when a switch operation is performed, a pop-up display will
be temporarily displayed on the multi-information display or the odometer/trip meter
screen (F SPORT models).
●Some pop-up displays can be set on/off. ( P. 111)
■Customization
The meter display can be customized on the multi-information display. (P. 111)
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indicates
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. 526)

■The meters and display illuminate when
The engine switch is in IGNITION ON mode.
■Welcome illumination of the analog speedometer
●When the driver’s door is opened, the analog speedometer will illuminate.
Then, when the driver’s door is closed, the analog speedometer will illuminate and go
off (pulsate) 3 times.
●In the following situations, the analog sp eedometer will not pulsate even though the
driver’s door is opened and closed:
• Within 60 seconds after the an alog meter pulsation completes
• Within 60 seconds of turning the engine switch off
■Variable red zone
■Eco driving meter
●The number of blue segments displayed on the eco driving meter decreases/increases
depending on the vehicle acceleration. Use this meter as a guideline when you wish to
drive in an eco-friendly manner that reduces fuel consumption.
However, on a downward grade where the ve hicle can accelerate without the acceler-
ator pedal being depressed, the eco driv ing meter may not display the eco-driving
state correctly.
●When the shift lever is moved to P, N or R, the segments will turn gray and the eco driv-
ing meter will not operate.
To help protect the engine, the engine speed is
controlled by starting the red zone of the
tachometer at different engine speeds ranging
from 3700 rpm to 7300 rpm depending on the
engine coolant temperature.
Before driving under extremely high load condi-
tions, make sure to su
fficiently warm up the
engine.
