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

The brightness of the instrument panel lights 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 either the brightest or darkest setting, the automatic
adjustment will not be performed.

■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, a pop-up display will be temporarily displayed on the multi-informa-
tion display or the odometer/trip meter/maintenance required information screen.
Some pop-up displays can be set on/off. ( P. 543)
■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.
■Clock settings
■Customization
The meter display can be customized on the multi-information display.
(Customizable features: P. 542)
If the screen shown to the right is displayed
when trying to change the time display method
through ( P. 106) on the multi-infor-
mation display, the system may be malfunction-
ing.
Have the vehicle inspected by your Lexus
dealer.
WARNING
■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, 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, causing
rapid and excessive engine braking and possibly an accident resulting in death or
injury.
