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.
●If the engine coolant temperature gauge is in the red zone (H), the engine may be
overheating. In this case, immediately stop the vehicle in a safe place, and check the
engine after it has cooled completely. (P. 5 9 7 )

Odometer and trip meter display
Odometer:
Displays the total distance the vehicle has been driven
Tr i p m e t e r :
Displays the distance the vehicle has been driven since the meter was last reset. Trip
meters “A” and “B” can be used to record and display different distances indepen-
dently.
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 guid eline 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 limit 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 dis-
plays for SPORT S mode and
SPORT S+ mode can be changed on
the settings display of the multi-infor-
mation display.

The engine speed reaches or
exceeds 3600 rpm, an afterimage
of the tachometer will be displayed
at the highest engine speed for
approximately 1 second.
■Odometer/Trip meter
Switches between odometer and
trip meter displays. When the trip
meter is displayed, pressing and
holding the button will reset the trip
meter.

■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, th e 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 speedometer will no t pulsate even though the
driver’s door is opened and closed:
• Within 60 seconds after the analog meter pulsation completes
• Within 60 seconds of turn ing the engine switch off
■Va r i a b l e r e d z o n e
■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 vehicle can accelerate without the acceler-
ator pedal being depressed, the eco driving 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.
Instrument panel light control

2
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 sufficiently warm up the
engine.

■Instrument panel brightness adjustment
The instrument panel brig htness levels when the tail ligh ts are on and off can be adjusted
individually. However, when the surroundings ar e bright (daytime, etc.), turning on the tail
lights will not change the instru ment panel brightness. At this time, any adjustments made
to the instrument panel bright ness levels will be applied to both settings at once.
■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 change d 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 pe rformed, a pop-up display will
be temporarily displayed on the multi-information display.
●Some pop-up displays can be set on/off. ( P. 1 1 9 )
■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. 1 1 0 )

■Suspension of the settings display
In the following situations, operation of the settings display will be temporarily sus-
pended.
●When a warning message appears on the multi-information display
●When the vehicle begins to move
■Tire pressure
●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 infla-
tion pressure after inflation pressure has been adjusted.
●“---” may be displayed if the tire information cannot be determined due to unfavorable
radio wave conditions.
●Tire inflation pressure changes with temperat ure. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.
■When disconnecting and reconnecting battery terminals
The drive information data will be reset.
■Liquid crystal display

■Caution for use while driving
●When operating the multi-information display while driving, pay extra attention to the
safety of the area around the vehicle.
●Do not look continuously at the multi-info rmation display while driving as you may fail
to see pedestrians, objects on the road, etc. ahead of the vehicle.
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal information
display. At extremely low temperatures, th e 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 cau se the driver to downshift again, causing
rapid and excessive engine braking and po ssibly an accident resulting in death or
injury.
■Cautions during setting up the display
As the engine needs to be running during sett ing up the display, ensure that the vehicle
is parked in a place with adequate ventila tion. In a closed area such as a garage,
exhaust gases including harmful carbon mo noxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.
NOTICE
■While setting up the display
To prevent battery discharge, ensure that th e engine is running while setting up the dis-
play features.
