Heated Exterior Mirror
The rear window defrost switch controls the operation of the heated exterior mirror glass. The heated exterior mirror glass only operates when the rear window defrost system is ON. The heated exterior mirror glass power is supplied by the rear window defrost relay through SJB fuse 9 (10A), which isolates the heated exterior mirror system from the rear window defrost system in the event of a concern.
Memory Exterior Mirror
The memory mirror function recalls the preferred positioning of the exterior mirror motors when the transmission is in the PARK or NEUTRAL position and the door mounted switches or the remote keyless entry (RKE) transmitter are activated.
Each exterior mirror motor is equipped with a potentiometer, which the driver door module (DDM) and driver seat module (DSM) use to monitor the position of the mirrors. The DDM constantly tracks LH mirror motor position. The DSM constantly tracks RH mirror motor position. When a mirror motor position is stored in memory by the operator, the module will retain this position in memory for future recall. The position of the mirror motors are stored within the DDM and DSM memory as long as the modules retain power. When a memory position is recalled by the operator, the DDM and DSM will power the exterior mirror motors simultaneously and monitor the potentiometer circuits. When the stored memory position is reached, the DDM and DSM will remove power from the exterior mirror motors. If the exterior mirror control switch is operated during a memory recall, the DDM and DSM will stop the memory recall and respond to the exterior mirror control switch command.
For information on the DDM, refer to MULTIFUNCTION ELECTRONIC MODULES article.
For information on the DSM and Memory Position Programming, refer to SEATING article.
Auto-Dimming Mirrors
The interior rear view and LH exterior mirror may be equipped with an auto-dimming feature. This feature automatically reduces the glare caused by headlamps reflecting in the mirror. The auto-dimming feature is disabled when the vehicle is in REVERSE. Power is supplied to the auto-dimming interior mirror when the ignition is in the RUN or ACC position.
The auto-dimming interior rear view mirror has 2 photoelectric sensors that detect forward and rearward light conditions, and based on those inputs, adjusts the reflectance level of the interior rear view mirror and LH exterior mirror to eliminate unwanted glare. The reflectance level of the mirror glass is variable and depends on the amount of rear glare in relation to ambient light conditions in front of the interior mirror.
When the forward sensor detects daytime conditions, the rearward sensor is inactive, and the mirror glass stays in a high reflectance mode. When the forward sensor detects nighttime conditions, the rearward sensor is active and detects glare from the headlights of vehicles approaching from the rear, or other glare producing light sources. To provide increased visibility when backing up, the interior rear view mirror glass and LH exterior mirror glass will automatically return to a high reflectance mode whenever the selector lever is placed in REVERSE.
If the forward or rearward sensors are blocked, the auto-dimming interior rear view mirror and LH exterior mirror might not work correctly.
Puddle Lamps
The exterior mirrors may be equipped with puddle lamps, which will illuminate when the interior lights are turned on by opening a door or by pressing the unlock button on the remote transmitter, if equipped. For information on the mirror-mounted puddle lamps, refer to EXTERIOR LIGHTING article.
