System Operation - Exterior, Power

All functions of the power mirror feature are integrated into one switch module. The left and right side selection button selects which side is active and a directional pad is used for directional control. Neutral is achieved by placing the selection button in the center position.

When the exterior mirror directional pad switch is pressed left, right, up or down with the LH or RH exterior mirror selected, the switch then supplies voltage and ground to the appropriate exterior mirror motor. The switch controls the glass movements by reversing polarity of the voltage and ground circuits being supplied to each motor.

System Operation - Exterior, Heated

On vehicles equipped with rear window defrost, the heated exterior mirror glass operates when the rear defrost system is activated.

The heated mirrors are heated for a period of 10 minutes when the engine is running and the defrost system is activated.

The LH and RH heated exterior mirror glass voltage is supplied by the rear window defrost relay through BJB .

If equipped, the rear window defrost can also be commanded on and off by touching the rear window defrost button located on the touchscreen interface (FDIM ). For additional information on voice or touchscreen commanded features, refer to the Owner's Literature.

System Operation- Interior Manual-Dimming

The manual interior rear view mirror can be adjusted from a day position to a night position to reduce unwanted glare caused by headlamps from behind the vehicle. Adjusting the interior mirror is accomplished by using the day/night tab, located on the bottom of the interior mirror. Pulling the tab rearward, towards the driver, adjusts the mirror to the night position. Pushing the tap forward, away from the driver, adjusts the mirror to the day position.

System Operation- Interior Auto-Dimming

The interior auto-dimming mirror uses 2 integral photoelectric sensors to determine the exterior lighting conditions. When the forward facing sensor detects daytime conditions, the rearward facing sensor is inactive and the mirror glass stays in a high reflectance mode. When the forward facing sensor detects nighttime conditions, the rearward facing sensor is active. During nighttime conditions, the mirror stays in a high reflectance mode until bright lights (glare) are detected by the rearward facing sensor. When bright lights (glare) are detected by the rearward facing sensor, the mirror glass is electronically darkened in proportion to the brightness of the glare detected from the rear of the vehicle. To provide increased visibility when backing up, the interior rear view mirror automatically returns to a high reflectance mode whenever the transmission is in reverse, regardless of exterior lighting conditions.

Component Description

Exterior Mirror Control Switch

The exterior mirror control switch is a momentary contact switch that allows the driver to adjust the selected exterior mirror glass up, down, left or right. The exterior mirror selection switch is integral to the exterior mirror control switch and allows the driver to determine which exterior mirror will be adjusted.

Exterior, Power Rear View Mirrors

Each exterior mirror has 2 bi-directional motors that are used to control the up, down, left and right movement of the exterior mirror glass.

If equipped with heated mirrors, the heated exterior mirrors use heating elements that are integral to the exterior mirror glass.

The exterior mirrors may be equipped with turn signals. For more information regarding the turn signals,

The exterior mirrors may include puddle lamps. For additional information on the mirror-mounted puddle lamps,

The exterior mirrors use a jumper harness between the vehicle wiring harness and the exterior mirror motors and the heated mirror glass. The exterior mirror jumper harness is integral to the exterior mirror. Before replacing an exterior mirror or motor, inspect the jumper harness for opens, shorted circuits or damaged and pushed-out pins. If a concern with the exterior mirror jumper harness exists, attempt to repair the jumper harness.

Interior Rear View Mirror - Manual-Dimming

The manual dimming interior rear view mirror has a lever at the back of the mirror that must be pulled forward or pushed rearward by the driver to activate the manual dimming function. Manual dimming is completely controlled by the driver.

Interior Rear View Mirror - Auto-Dimming

The auto-dimming rear view mirror has 2 photoelectric sensors, one on the front of the mirror (facing the windshield) and one on the rear of the mirror (at the top of the mirror glass). Based on inputs from these sensors, the mirror internally calculates and adjusts the reflectance level of the interior rear view mirror glass to eliminate unwanted glare. The reflectance level of the mirror glass is variable and depends on the amount of rear glare detected in relation to ambient light conditions in front of the interior mirror.
