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 (dayti me, 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-info rmation 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)

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 spee dometer 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 th is 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.

The G-force values may not be zero even when the vehicle is parked, such as when it is
parked on an incline. ■
Suspension of the settings display ●
Some settings cannot be changed while driv ing. When changing settings, park the
vehicle in a safe place. ●
If a warning message is displa yed, operation of the settin gs display will be suspended.■
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 position 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.Eco Driving Indicator Light
During Eco-friendly acceleration (Eco driv-
ing), the Eco Driving Indicator Light will turn
on. When the acceleration exceeds the Zone
of Eco driving, or when the vehicle is stopped,
the light turns off.

parked on an incline. ●
The steering amount, accelerator pedal input, and brake fluid pressure displays are dis-
abled until the engine has warmed up (the variable red zone of the tachometer has
retracted to 7300 rpm).
After the engine has warmed up, these displays will be enabled. ●
Depending on the vehicle usage conditions, the brake fluid pressure display may not
reach its maximum reading even though the brake pedal is fully depressed. ●
