ARRANGEMENT OF COMBINATION METER

USA.

Except USA

Combination Meter

The combination meter controls the following items according to the signals received from each unit via CAN communication and the signals from switches and sensors.

Measuring instruments
- Speedometer
- Tachometer
- Engine coolant temperature gauge
- Fuel gauge
Indicator lamps
Warning lamps
Meter illumination control
Meter effect function
Information display

CLOCK SPECIFICATIONS

Operating voltage	(V)	11 - 16
Accuracy	(sec./day)	Approx. ± 6

NOTE:

The time is displayed on the information display. When a time lag of more than the above described accuracy occurs, the combination meter battery power supply voltage may be low. In this case, check 12 V battery for malfunction causing low power supply voltage. Models with the navigation system are free of time lag resulted from low power supply voltage because of the synchronization with GPS signals.

Master Speaker

The master speaker is installed in the top center of the instrument panel assembly.
The master speaker sounds with the signal from the combination meter.

Steering Switch

The steering switches are located on the steering wheel.
Transmits the steering switch signal to the combination meter.

No.	Switch name	Operation	Description
1.	RIGHT switch	Press	Switches the screen shown on the information display.
2.	LEFT/BACK switch	Press	Switches the screen shown on the information display. Switches the screen shown on the information display to the previous screen.
3.	OK switch	Press	Switches the screen shown on the information display.
	Scroll dial	Up	Moves up the item selected on the information display. Increases the set value displayed on the settings screen of the information display.
	Scroll dial	Down	Moves down the item selected on the information display. Decreases the set value displayed on the settings screen of the information display.
4.	Control switch	Press	Switches the screen shown on the information display to the short cut menu screen.

Illumination Control Switch

The illumination control switch is located on the instrument lower panel LH.
Transmits the following signals to the combination meter:
- Illumination control switch signal (+)
- Illumination control switch signal (−)

No.	Switch name	Operation	Description
1.	Illumination control switch (−)	Press	The brightness of the combination meter and information display can be adjusted.

Fuel Level Sensor Unit And Fuel Pump (Fuel Level Sensor)

Fuel level sensor unit and fuel pump (fuel level sensor) is located in the fuel tank.
Transmits the fuel level sensor signal to the combination meter.

Ambient Sensor

The ambient sensor is attached to the active grille shutter.
Ambient sensor measures ambient air temperature.
Ambient sensor transmits the ambient sensor signal to the combination meter.
Ambient sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
