| Maintenance required (*5) | An oil maintenance required indication will display to remind the driver to change the engine oil depending on the vehicle driving distance. |
| ILLUMINATION CONTROL |
- HINT:
- If the engine switch is turned on (IG), the illumination control operates as follows. However, all illuminations other than the tachometer needle turn off while cranking the engine.
The speedometer and tachometer needles illuminate starting from the base of the needles and moving to their tips.
These needles move to their maximum position and return to zero.
The fuel gauge and water temperature gauge light up, then the warning lights, indicator lights, multi-information display, and meter panel illumination come on.
| MULTI-INFORMATION DISPLAY |
*1: for Automatic Transmission
*2: with Clearance Sonar System
*3: with Intrusion Sensor
*4: with Intelligent AFS
*5: for 2AD-FHV
*6: with Dynamic Radar Cruise Control System
| Mode | Outline |
| Cruise Information | In the cruise information mode, seven types of information (Outside Temperature, Driving Range, Average Fuel Consumption, Average Fuel Consumption After Refueling, Current Fuel Consumption, Average Speed, and Sequential Gear Position (*1)) can be displayed. The display can be switched by using the DISP switch. |
| Warning | The warning mode display will interrupt the multi-information display immediately when a warning occurs. |
| Multi-switch | In the multi-switch mode, 6 switches (Clearance sonar ON/OFF (*2), Intrusion sensor ON/OFF (*3), AFS ON/OFF (*4), Priming ON/OFF (*5), SPEED indicator ON/OFF, TACH indicator ON/OFF) can be displayed. The switches can be changed using the satellite switch (RH switch, ON/OFF switch, LH switch). |

| INTEGRATION CONTROL & PANEL ASSEMBLY (without NAVIGATION SYSTEM)/MULTI-DISPLAY (with NAVIGATION SYSTEM) |
*1: without Navigation System
*2: with Navigation System
- HINT:
The integration control & panel assembly (*1) consists of two parts (passenger information display and heater control panel). These areas display the contents given in the table below.
The multi-display (*2) consists of four parts (navigation display, passenger information display, clock display, and heater control panel). These areas display the contents given in the table below.
| Item | Detail |
| Passenger information display | Displays the condition of the front passenger seat belt ON/OFF and the front passenger seat airbag ON/OFF. |
| Heater control panel | Displays the condition of the heater control panel. |

| MULTI-INFORMATION DISPLAY FLOW-CHART |
| DIAGNOSIS SYSTEM |
The combination meter assembly indicates the diagnosis mode by blinking the warning light or by blinking the warning message in the multi-information display.
- HINT:
The multi-information display shows "DIAG" when the engine switch is on (IG) .
Diagnosis information can be displayed on the multi-information display after connecting a jumper wire between terminals TC (J21-13) and CG (J21-4) of the DLC3 connector.
| SATELLITE SWITCH |
By using the satellite switch (RH switch, ON/OFF switch, LH switch), 6 different switch functions can be displayed and changed (SPEED indicator, TACH indicator, Intrusion sensor (*1), Clearance sonar (*2), AFS (*3), Priming (*4)).
While driving at 3 mph (5 km/h) or less, the switch except for clearance sonar (SPEED indicator, TACH indicator, Intrusion sensor (*1), AFS (*3), Priming (*4)) can be displayed.
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.
*1: with Intrusion Sensor
*2: with Clearance Sonar System
*3: with Intelligent AFS
*4: for 2AD-FHV
SPEED and TACH indicator
The SPEED indicator and TACH indicator come on when the vehicle speed or engine speed reaches the speed set using the satellite switch. The setting ranges of these indicators are shown in the table that follows.
Vehicle speed or engine speed can be set using the satellite switch.
These indicators consist of yellow and red dots that are arranged to form indicator rings.
When the set vehicle speed or engine speed is reached while driving, the red and yellow dots will turn on at the same time to cause amber light to illuminate the indicator ring.
However, if the vehicle or engine speed is set to the maximum speed of the indicator setting range, and the speed reaches this set speed, only red light will illuminate the indicator ring.
- HINT:
| Destination | Setting Range | Initial Setting | |
| LHD | 50 to 200 (km/h) | 130 (km/h) | |
| RHD | Cypriot and Irish | 50 to 160 (km/h) | 120 (km/h) |
| Others | 30 to 100 (mph) | 75 (mph) | |
| Engine | Setting Range | Initial Setting |
