Automatic Day/Night Mirror - Description






DESCRIPTION

An automatic dimming (day and night) inside rear view mirror is an available factory-installed option for this vehicle. Vehicles equipped with the automatic dimming inside rear view mirror are also available with an optional factory-installed automatic dimming outside rear view mirror for the driver side of the vehicle. In vehicles so equipped, this system will automatically change the reflectance of the inside and driver side outside rear view mirrors to protect the driver from the unwanted headlight glare of trailing vehicles while driving at night. Following are general descriptions of this optional equipment.

INSIDE





The automatic dimming inside rear view mirror (1) is able to automatically change its reflectance. The automatic dimming inside rear view mirror system is a completely self-contained unit that replaces the standard equipment manual prismatic inside rear view mirror. The two layers of conductive mirror glass with a thin layer of electrochromic material between them, the lighted mirror switch (3), two photocell light sensors (2), the mirror connector receptacle (4) and the electronic mirror control circuitry are all self-contained within the inside rear view mirror housing.

The automatic dimming mirror is secured to the same mounting button on the inside of the windshield glass and in the same manner that is used to mount the standard equipment manual prismatic mirrors. The mirror is connected to the vehicle electrical system through a dedicated take out and connector of the overhead wire harness. The automatic dimming inside rear view mirror receives battery current through a fused ignition switch output (run-start) circuit and a fuse in the Totally Integrated Power Module (TIPM), and will only operate when the ignition switch is in the ON or START positions.

The automatic dimming inside rear view mirror sensitivity cannot be repaired or adjusted. If any component of this unit is ineffective or damaged, the entire inside rear view mirror unit must be replaced. For service procedures, Interior Rearview Mirror - Removal and Interior Rearview Mirror - Installation.

OUTSIDE

The automatic dimming driver side outside rear view mirror is able to automatically change its reflectance. The automatic dimming outside rear view mirror replaces the standard equipment outside rear view mirror. The two layers of conductive mirror glass with a thin layer of electrochromic material between them is contained within the outside rear view mirror glass case. However, this mirror relies upon the photocells and mirror control circuitry of the automatic dimming inside rear view mirror to control its reflectance.

The automatic dimming outside rear view mirror is secured to the same mounting flag on the front door panel and in the same manner that is used to mount the standard equipment outside rear view mirrors. The mirror is connected to the vehicle electrical system through a dedicated take out and connector of the front door wire harness. The automatic dimming circuitry of the outside rear view mirror receives current through auto day/night mirror feed (+) and return (-) circuits from the inside rear view mirror, and will only operate when the ignition switch is in the ON or START positions.

The automatic dimming outside rear view mirror sensitivity cannot be repaired or adjusted. If any component of this unit is ineffective or damaged, the entire outside rear view mirror unit must be replaced. For service procedures, Outside Rearview Mirror - Removal and Outside Rearview Mirror - Installation.
