AUTO-DIMMING REARVIEW MIRROR/AUTO-DIMMING OUTER MIRROR
Purpose
-
The auto-dimming rearview mirror and the auto-dimming outer mirrors prevent the driver from being blinded by light from vehicles at the rear.
Function
-
The auto-dimming rearview mirror changes the reflection rate of the auto-dimming rearview mirror and the auto-dimming outer mirrors between 7% and 85% according to the level of the surrounding light and the glare level from vehicles at the rear.
NOTE:
-
The reflection rate of the auto-dimming rearview mirror is fixed at 50% or more when the selector lever (AT)/shift lever knob (MT) is shifted to the R position (AT/MT).
Glare level detection function
-
The auto-dimming rearview mirror detects the level of the surrounding light and glare from vehicles at the rear using the light sensor.
Home link function
-
A gate of a house or garage, or gate lamp can be operated remotely by operating the home link button built into the auto-dimming rearview mirror.
NOTE:
-
When two or more home link buttons are pressed simultaneously, the home link button with the smallest number is operated first.
-
-
The frequency (remote controller information) for operating each gate of the house or gate lamp can be stored to the three home link buttons built into the auto-dimming rearview mirror.
-
The stored information is not cleared even if the battery power is disconnected.
-
All the stored information can be cleared by pressing and holding home link buttons 1 and 3 simultaneously for 10 s or more.
NOTE:
-
If the learned information is cleared, the auto-dimming rearview mirror flashes the home link button indicator for approx. 10 s.

Operation
1. When the auto-dimming rearview mirror switch is turned on, the auto-dimming rearview mirror initiates the detection of the glare level.
2. The auto-dimming rearview mirror detects (1) the level of the surrounding light and glare level from vehicles at the rear using the light sensor.
3. The auto-dimming rearview mirror changes (2) the voltage input to the auto-dimming rearview mirror and the auto-dimming outer mirrors according to the level of the surrounding light and the glare level from vehicles at the rear.
4. The auto-dimming rearview mirror and the auto-dimming outer mirrors change the reflection rate between 7% and 85% according to the input voltage.
5. When the auto-dimming rearview mirror receives an R position signal from the electrical supply unit (ESU), the reflection rate of the auto-dimming rearview mirror and the auto-dimming outer mirrors are fixed (3) at 50% or more.
