■Speed indicator (F SPORT models)
When the vehicle reaches a set
speed, indicators will be displayed
on both sides of the displayed speed
unit.
• The indicators will be displayed in
yellow (correspondi ng to a speed set
by a user) or red (fixed at 100 mph
[160 km/h])
*.
• The desired vehicle speed at which
the speed indicator will begin to be
displayed can be set in of the
multi-information display. ( P. 111)
• The default setting of the indicator is off. This setting can be changed in of the
multi-information display. ( P. 111)
*: Always observe the legal speed limi t when driving on public roads.
■Rev indicator (F SPORT models)
When the engine speed reaches a
set speed, a ring-shaped indicator
will be displayed on the tachometer.
The desired engine speed at which
the Rev indicator will begin to be dis-
played can be set on of the multi-
information display. (
P. 111)
■Rev peak (F SPORT models)

■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)

Displays warning me ssages in case of a malfunction ( P. 460)
Fuel gauge
Engine coolant temperature gauge
Displays the engine coolant temperature. If the engine coolant temperature gauge
indicator ( ) enters the red zone, a buzzer will sound and the indicator will turn red
and start flashing. Also, a warning message will be displayed.
Engine oil temperature gauge
Displays the engine oil temperature. If the engine oil temperature gauge indicator
( ) enters the red zone, the indicator will turn red and start flashing.
Outside temperature
Displays the outside temperature within the range of -40°F (-40°C) to 122°F
(50°C). Low outside temperature indicator comes on when the ambient temperature
is 37°F (3°C) or lower.
Tachometer
Displays the engine speed in revolutions per minute

Odometer and trip meter display
Odometer:
Displays the total distance the vehicle has been driven
Trip meter:
Displays the distance the vehi cle has been driven since the meter was last reset. Trip
meters “A” and “B” can be used to record and display different distances inde-
pendently.
Eco driving meter
Displays the vehicle acceleration. The more rapidly the vehicle is accelerated, the
lower the number of blue segments displayed, indicating that your driving is less eco-
friendly. This meter is designed as a guideline to show the eco-friendliness of your
driving.

■Speed indicator
When the vehicle reaches the set
speed, the speed unit display will
turn yellow.
The indicators will be displayed in
yellow (corresponding to a speed set
by a user) or red (fixed at 100 mph
[160 km/h])
*.
This setting can be enabled on the
multi-information display.
*: Always observe the legal speed limi t when driving on public roads.
■Rev indicator (SPORT S mode/SPORT S+ mode)
When the shift lever is in M, an indi-
cator on the tachometer will be dis-
played in 3 steps. When the 3rd
level indicator is displayed, the indi-
cator will flash and a buzzer will
sound to notify you of shift-up timing.
The indicator may be displayed when
downshifting, depending on the
engine speed.
*: These illustrations show the default
meter display for SPORT S mode
and SPORT S+ mode. The meter
displays for SPORT S mode and
SPORT S+ mode can be changed on

■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.

■Dimming the analog speedometer lighting
The analog speedometer lighting will be dimm ed when the ambient light is bright, such
as during the daytime, and SPORT S or SPORT S+ mode is selected.
■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 sy stem 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.
●Some pop-up displays can be set on/off. ( P. 129)
■Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is characteristic
of liquid crystal displays, and there is no problem continuing to use the display.
■Customization
The meter display can be customized on the multi-information display. (P. 129)
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator of the tachometer enter the red zone, as it represents the
engine speed range which exceeds the maximum safe engine speed.
●In the following situations, th e engine may be overheating. In this case, immediately
stop the vehicle in a safe place, and check the engine after it has cooled completely.
