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 beoverheating. In this case, immediately stop the vehicle in a safe place, and check theengine after it has cooled completely. ( P. 659)

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°C (-40°F) to 50°C
(122°F). Low outside temperature indicator comes on when the ambient temperature
is 3°C (37°F) or lower.

Odometer and trip meter display
Odometer:
Displays the total distance the vehicle has been driven
Trip meter:
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 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 guid eline to show the eco-friendliness of your
driving.

■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 speedometer will not pulsate even though the
driver’s door is opened and closed:
• Within 60 seconds after the analog 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 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

To help protect the engine, the engine speed is
controlled by starting the red zone of the tachometer at different engine speeds rangingfrom 3700 r/min to 7300 r/min 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 brightness levels when th e tail lights 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 in strument panel brightness.
■Dimming the analog speedometer lighting
The analog speedometer lighting will be dimme d 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 20 km/h [12 mph])
• 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 any authorized Lexus de aler or repairer, or another duly qualified
and equipped professional.
■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. 148)
■Liquid crystal display
Small spots or light spots may appear on th e 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. 139)
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, 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. 659)
• The engine coolant temperature gauge indicator ( ) is in the red zone and flash- ing.
• The engine oil temperature gauge indicator ( ) is in the red zone and flashing.

2564-2. Driving procedures
RC200t_RC F_EE(OM24728E)
To enter M mode, shift the shift lever to M. Gears can then be selected by oper-
ating the shift lever or paddle shift switches, allowing you to drive in the gear of
your choosing.
Upshifting
Downshifting
The gear changes once every time the shift lever or paddle shift switch is oper-ated.
The selected gear, from M1 to M8, will be fixed and displayed in the meter.
When in the M position, the gear will not change unless the shift lever or pad-
dle shift switches are operated.
However, even when in the M position, the gears will be automatically
changed in the following situation:
●When vehicle speed drops (downshift only).
●When a gear change is necessary to protect the engine or automatic trans-
mission when the engine coolant temperature or automatic transmission
fluid temperature is low, or other reasons.
In the following situations, the gear will not shift even if the shift lever or paddle
shift switches are operated.
●“1st Gear not available due to slippery road surface” is displayed on the
multi-information display.
●The vehicle speed is low (upshift only).

4-6. Driving tips
●Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine coolant
• Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the rear tires.*
Ensure that all tires are the specified size and brand, and that chains match the size of the tires.
*: Tire chains cannot be mounted on vehicles with front and rear tires of differing
sizes.
●Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine coolant
• Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires.
Ensure that all tires are the specified size and the same brand.
●Tire chains can only be installed on the rear tires. However, tire chains cannot
be installed on 275/35ZR19 rear tires.
Before installing tire chains, change all four tires and wheels to those of the
specified size for use with tire chains (front tires: 235/40ZR19, rear tires:
235/40ZR19, wheels: 19 x 8 1/2 J 45 inset). Use the specified type of tire
chains and install them on the rear tires only.

●Engine missing, stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (However, water dripping from the air conditioning sys-
tem after use is normal.)
●Change in exhaust sound (This may indicate a dangerous carbon monoxide leak. Drive with the windows open and have the exhaust system checked immediately.)
●Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
●Vehicle pulls to one side when driven straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches the floor,vehicle pulls to one side when braking
●Engine coolant temperature continually higher than normal ( P. 118, 124)
If you notice any of these clues, take your vehicle to any authorized Lexus dealer or repairer, or another duly qualified and equipp ed professional as soon as possible. Your vehicle may need adjustment or repair.
WARNING
■If your vehicle is not properly maintained
Improper maintenance could result in serious damage to the vehicle and possible death or serious injury.
