(a) This system has the following functions: electrical remote control mirror function, power retract mirror function, mirror heater function and automatic glare-resistant EC mirror function.
FUNCTION OF MAIN COMPONENT
| Component | Function | |
|---|---|---|
| Outer rear view mirror assembly | Vertical mirror motor | Receives signals from the outer mirror switch assembly and adjusts the mirror surface position vertically. |
| Horizontal mirror motor | Receives signals from the outer mirror switch assembly and adjusts the mirror surface position horizontally. | |
| Mirror heater | When the mirror heater switch (rear window defogger switch) on the air conditioning control assembly is operated, the air conditioning amplifier assembly detects the switch operation via LIN communication. The air conditioning amplifier assembly operates the semiconductor power integration ECU and mirror heaters in accordance with the switch operation. | |
| EC mirror cell | Varies the reflection rate of the mirror through function of EC elements. | |

| Function | Outline |
|---|---|
| Electrical remote control mirror function | When the outer mirror switch assembly is operated, this function moves the mirror surface vertically or horizontally to enable the driver to attain an optimal mirror angle. Turning the mirror select switch to the R position operates the right side mirror, and turning the mirror select switch to the L position operates the left side mirror. |
| Mirror heater function | Turns on the mirror heaters when the rear window defogger is turned on. The rear window defogger and mirror heaters automatically turn off 15 minutes after the rear window defogger and mirror heaters were activated. |
