Switches between odometer, trip meter
and maintenance required information
displays. When the trip meter is dis-
played, pressing and holding the button
will reset the trip meter.
The brightness of the instrument panel lights can be adjusted.

■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.
■Limitation of brightness adjustment
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.

■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 changing the starting position of
the tachometer’s red zone depending on the
engine coolant temperature within a range from
3700 rpm to 7300 rpm.
Before driving under extremely high load condi-
tions, make sure to su fficiently warm up the
engine.

■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.
■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 screen 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 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.
Some pop-up displays can be set on/off. ( P. 545)
■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.
(Customizable features: P. 542)
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.

GS350_GS F_OM_OM30J07U_(U)3-1. Key information
■Panic mode
■When required to leave the vehicle’s key with a parking attendant
Turn the trunk opener main switch off, lock the glove box and armrest door as circum-
stances demand. (
P. 151, 341, 351)
Remove the mechanical key for your own use and provide the attendant with the elec-
tronic key only.
■If you lose your mechanical keys
New genuine mechanical keys can be made by your Lexus dealer using the other
mechanical key and the key number stamped on your key number plate. Keep the plate
in a safe place such as your wallet, not in the vehicle.
■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any but-
tons on the electronic key while inside the airc raft cabin. If you are carrying an electronic
key in your bag etc., ensure that the buttons are not likely to be pressed accidentally.
Pressing a button may cause the electronic key to emit radio waves that could interfere
with the operation of the aircraft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year and a
half.)
●If the battery becomes low, an alarm will sound in the cabin when the engine stops.
(  P. 471)
●As the electronic key always receives ra dio waves, the battery will become depleted
even if the electronic key is not used. The following symptoms indicate that the elec-
tronic key battery may be depleted. Replace the battery when necessary. ( P. 411)
• The smart access system with push-button start or the wireless remote control does
not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of the
following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
•Table lamps
• Induction cookers
When is pressed for longer than about
one second, an alarm will sound intermittently
and the vehicle lights will flash to deter any per-
son from trying to break into or damage your
vehicle.
To stop the alarm, press any button on the elec-
tronic key.
