METER / GAUGE SYSTEM DETAILS

Multi-information Display

1. Display Function Flow

   
   

   1. The multi-information display flow can be switched as shown in the flow chart below:

      

      No.	Transition Condition
      *1	Conditions are not met and all new messages have been displayed.
      *2	If the display conditions for 2 or more messages are met, relevant messages are alternately displayed for 2 seconds each.
      *3	If the engine switch is turned off during the "Opening" display, the "Opening" display will be shown from the beginning.
      *4	If the DISP switch is used to change from an advisory message to the cruise information display screen, repeatedly operating the DISP switch will cycle through the cruise information screens and then return the advisory message if the display conditions are still met.
      *5	If the DISP switch is not operated for more than 6 seconds with any of the caution or warning message display conditions still met, the relevant caution or warning messages are displayed.
      *6	Conditions for displaying new messages are met, or the vehicle speed is more than 8 km/h (5 mph).

2. Maintenance Required Reminder Function (Models for Australia)

   
   

   1. A maintenance required reminder message will appear to inform the driver of maintenance requirements.

   2. The combination meter assembly calculates the vehicle driving distance based on the signals from the skid control ECU.

   3. There are 2 types of warnings: one is displayed when the vehicle driving distance is 14500 km/h or more since the last time the system was reset, and the other is displayed when the driving distance is 15000 km/h or more.

   4. The maintenance required reminder message appears on the multi-information display as follows:

      14500 km/h or more	15000 km/h or more
      MAINTENANCE REQUIRED SOON appears for approximately 15 seconds	MAINTENANCE REQUIRED warning remains on

   5. After the required maintenance has been performed, the accumulated vehicle driving distance memorized in the combination meter assembly should be reset to zero using the ODO/TRIP switch.

      Tech Tips

      The accumulated vehicle driving distance memorized in the combination meter assembly can be reset using the following procedure.

      
      

      • Turn the engine switch on (IG), and make sure that the TRIP A is displayed on the multi-information display.

      • Turn the engine switch off. While pushing the ODO/TRIP switch, turn the engine switch on (IG).

      • With the engine switch on (IG), keep holding the ODO/TRIP switch (for at least 5 seconds) with the multi-information display counting down. Release the ODO/TRIP switch when the resetting procedure has completed.

      • As the resetting completes, the multi-information display will show complete message for 1 second or the odometer will display "000000" for 1 second.

3. Rear Seat Belt Warning (Models for Australia)

   
   

   1. The rear seatbelt warning function indicates the state of the rear seat belts using the telltale light assembly.

   2. The combination meter assembly sends a rear seat belt warning signal to the telltale light assembly based on the rear seat belt buckle switches and courtesy switches for the rear doors. When the signal is received, the telltale light assembly operates the lights. If a warning is necessary, the buzzer in the combination meter assembly will also sound.

   3. The flow of operations that results in a rear seat belt warning is as follows:

      

      Step	Condition Transition	Multi-information Display	Buzzer
      (a)	The engine switch is off.	Warning is not displayed.	No Sound
      (b)	A rear door is opened then closed.
      (c)	The engine switch is turned on (IG). A seat belt is fastened.	In this case, all seats will be displayed as being unfastened regardless of the number of occupants. If seat belts are then fastened, the display for the relevant seat will go off. The warning will be displayed for approximately 34 seconds and then go off.
      (d)	Any of the rear seat belts are unfastened.	Seats with an unfastened seat belt will be displayed regardless of the number of occupants.	If the vehicle speed exceeds 20 km/h (12 mph): Sounds for 30 seconds*1 Sounds for an additional 90 seconds*2
      (e)	When one of the following conditions is met, the buzzer will stop sounding. The seat belt is refastened. Vehicle speed is lower than approximately 2 km/h (1.2 mph) and either the parking brake is applied or the shift lever is in P.	Seats with an unfastened seat belt will be displayed regardless of the number of occupants. The warning message will be displayed for approximately 34 seconds and then go off.	Stops sounding

   
   

   • *1: Sound cycle is 1.2 seconds

   • *2: Sound cycle is 0.4 seconds

4. Cruise Information Mode Function

   
   

   • The cruise information is displayed in the following order each time the DISP switch of the steering pad switch assembly is pressed.

   *a	The item that is always displayed does not appear when the cruise information item is switched as shown above.	*b	The item selection screen is displayed.
   	DISP switch pressed briefly.		DISP switch pressed and held.

   
   

   • The cruise information mode items displayed are as follows:

   No.	Information	Outline
   (1)	Eco Driving Indicator Zone Display	Displays Eco driving state by the movement of the bar on Eco driving indicator zone display after the comparison of Eco driving range with the current acceleration. Displays a value that has been calculated by the ECM. When the engine switch is turned on (IG), the ECM calculates the Eco driving ratio based on the vehicle speed, accelerator pedal operation, shift position, engine speed, shift range and driving mode signals. This display is updated every 0.2 seconds.
   (2)	Ambient Temperature	Displays the ambient temperature.
   (3)	Current Fuel Consumption	Displays a value that has been calculated by the combination meter assembly. When the engine switch is turned on (IG), the combination meter assembly calculates this value based on the distance driven and the fuel consumption volume (fuel injection signal from the No. 1 injector). This display is updated every 0.5 seconds.
   (4)	Average Fuel Consumption After Refueling	Displays the value calculated by the combination meter assembly based on the distance driven since refueling and the fuel consumption volume (fuel injection signals from the No. 1 injector). The combination meter assembly determines the vehicle has been refueled through the signal from the fuel sender gauge. This display is updated every 10 seconds.
   (5)	Average Fuel Consumption	Displays a value that has been calculated by the combination meter assembly based on the distance driven and the fuel consumption volume (fuel injection signal from the ECM). This display is updated every 10 seconds.
   (6)	Average Speed	Displays the average vehicle speed calculated by the combination meter assembly based on the engine start signal and vehicle speed signal. This display is updated every 10 seconds.
   (7)	Cruising Range	Displays a value that has been calculated by the combination meter assembly. When the engine switch is turned on (IG), the combination meter assembly calculates the range based on continuously monitoring and storing information on fuel consumption data, and the residual fuel volume. This display is updated every 10 seconds.
   (8)	Elapsed Time	Displays the length of time since the engine was started.
   (9)	Tire Inflation Pressure	Displays the tire inflation pressure.
   (10)	Settings	Customizes the combination meter assembly language display, Eco Driving Indicator Light and instantaneous fuel consumption gauge deactivated or activated display states.
   (11)	Blank Screen	-

5. Customization Function

   
   

   • In the settings screen of cruise information mode, pressing and holding the DISP switch enters setting mode.

   • Press the DISP switch briefly to select the item to be customized. Press and hold the DISP switch to confirm the selection.
