Kia Sportage: Electro Chromic Inside Rear View Mirror / Description and operation
The ECM (Electro Chromatic inside rear view Mirror) is one that automatically
dims to protect the driver’s eyes when it senses light reflecting from the car
behind. The sensor in the mirror detects the brightness and if the headlight
from the car behind is reflected on the mirror, the chemical layer inside the
mirror reacts to glare and adjusts the reflectivity from 10 to 70%. When switching
to the reverse gear, the mirror becomes bright regardless of the surrounding.
The ECM receives voltage, ground and reverse gear signals, and uses two sensors
to measure the intensity of glaring.
1. |
The forward facing sensor determines whether the surrounding space is
dark enough to activate the function.
|
2. |
The rearward facing sensor detects the glare on the mirror. If the glare
is detected, the sensor transmits the signal for the mirror to dim
|
3. |
The ECM is darkened to the level as determined by the rearward looking
sensor. When the glaring is no longer detected, the mirror stops functioning.

Automatic-dimming Function |
To protect your vision during nighttime driving, your mirror will automatically
dim upon detecting glare from the vehicles traveling behind you. The auto-dimming
function can be controlled by the Dimming ON/OFF Button :
1. |
Pressing and holding the Feature Control button for more than 3 but
less than 6 seconds turns the auto-dimming function OFF which is indicated
by the green Status Indicator LED turning off.
|
2. |
Pressing and holding the Feature Control button again for more than
3 but less than 6 seconds turns the auto-dimming function ON which is
indicated by the green Status Indicator LED turning on.
The mirror defaults to the "ON" position each time the vehicle
is started.
