Honda HR-V: Description
AUTOMATIC DIMMING MIRRORS SYSTEM DESCRIPTION - CONTROL/FUNCTION
When the automatic dimming off button is turned ON, the control unit receives signals from each sensor. Based on the difference between the two lux levels (the light outside the vehicle and the light from the headlights of the other vehicle, etc.) the control unit controls the electro-chromic gel to reduce glare.
AUTOMATIC DIMMING MIRRORS SYSTEM DESCRIPTION - OVERVIEW
The automatic dimming inside mirror has a front-facing lux level sensor, rear-facing lux level sensors, and control unit. This dimming function is canceled when the shift lever is in R position, or when the automatic dimming off button is turned OFF.

Manual Function
The power mirror defogger is controlled by the rear window defogger/power mirror defogger switch.
Defogger Timer Function
The power mirror defogger system has a timer control function that is controlled by the climate control unit.
The timer control is operated by turning the vehicle to the ON mode, then turning on the rear window defogger switch. The timer operating time varies according to ambient temperature. If the rear window defogger/power mirror defogger switch is turned on when the timer is active, it toggles between ON and OFF every time the switch is pressed.

Auto Power Mirror Defogger Function
When the climate control unit receives a signal that the outside air temperature is 41ºF (5ºC) or below from the outside air temperature sensor, the climate control unit automatically turns on the left and right power mirror defoggers within 10 seconds after the vehicle is in the ON mode. The power mirror defogger output automatically stops in 10 minutes as a result of its timer. If the rear window defogger/power mirror defogger switch is pressed during the power mirror defogger output, the climate control unit stops the auto operation function immediately.
POWER MIRRORS SYSTEM DESCRIPTION - OVERVIEW
Some models come equipped with the remote controlled door mirrors and mirror defogger control.
