    3. Multi-information Display

      Tech Tips


      • The multi-information display is located in the upper center of the combination meter.

      • The display shows a message or animation for each of the functions described in the table below.

      Item Detail
      Cruise information display Outside temperature

      Seven types of information (outside temperature, average fuel consumption, average fuel consumption after refueling, average vehicle speed, possible running distance, instant fuel consumption, and A/T shift position) can be displayed.

      The display can be switched by using the DISP switch.
      Average fuel consumption
      Average fuel consumption after refueling
      Average vehicle speed
      Possible running distance
      Instant fuel consumption
      A/T shift position
      Warning display Door warning Interrupts the multi-information display immediately when a warning occurs.
      Each system warning
      Satellite switch

      In the satellite switch mode, 4 functions (Sonar*2, Intrusion Sensor*3, DRL, PCS brake*4) can be displayed.

      The function can be changed using the satellite switch (RH switch, ON/OFF switch, LH switch).
      Dynamic Radar Cruise Display*1 Displays the operating condition of the dynamic radar cruise control.
      ODO/TRIP display This display switches between odometer, trip meter A, and trip meter B in accordance with the operation of the TRIP meter reset knob.
      Parking Assist-sensor Display*2 Displays the location of an obstacle and the approximate distance between the vehicle and the obstacle and displays malfunction warning messages about sensor freezing or presence of dirt on the sensors.

      • *1: w/ Dynamic Radar Cruise Control System

      • *2: w/ Lexus Parking Assist-sensor System

      • *3: w/ Intrusion Sensor

      • *4: w/ Pre-crash Safety System

  3. ENGINE OIL TEMPERATURE GAUGE

    A015ZGSE01

    1. The meter CPU uses the engine oil temperature sensor to determine the temperature of the engine oil. The resistance of the engine oil temperature sensor will vary between approximately 30 kΩ or higher with the engine oil temperature is 0°C (32°F), and approximately 0.3 kΩ with the engine oil temperature is 155°C (311°F). Voltage measured at this point will vary as the engine temperature is changed.

      The engine oil temperature gauge displays the engine oil temperature using seven bars. The meter CPU calculates the engine oil temperature based on signals from the engine oil temperature sensor via the direct line. When the engine oil temperature becomes 140°C (284°F) or higher, all the bars blink and the warning message is displayed in the multi-information display.

      Tech Tips


      • If the circuit is open, the left bar blinks.

      • If the circuit is shorted, all bars blink and engine oil temperature warning light comes on.

  4. SATELLITE SWITCH


    1. A0162R6

      By using the satellite switch (RH switch, ON/OFF switch, LH switch), 4 different switch functions can be displayed and changed (Intrusion sensor*1, Sonar*2, DRL, PCS brake*3).


      • *1: w/ Intrusion Sensor

      • *2: w/ Lexus Parking Assist-sensor System

      • *3: w/ Pre-crash Safety System

      Tech Tips


      • When the engine switch on (IG) while driving at 3 mph (5 km/h) or less, the switch except for Lexus parking assist-sensor system*2 can be displayed as shown in the illustration below.

      • The switch functions displayed are changed in the order shown in the illustration using the satellite switch (RH switch, LH switch). The function can be set using the ON/OFF switch.

      • The display automatically returns to the previous display 6 seconds after the satellite switch is operated. It will return to the previous display immediately if the DISP switch is operated.
