Mirrors: Description and Operation

REAR VIEW MIRRORS

The rear view mirror components consist of:
- the interior mirror.
- the auto dimming mirror (optional).
- the exterior power folding mirror (optional).
- the exterior mirror.
- the exterior mirror control switch.
- the memory set switch.

The interior mirror:
- is windshield mounted.
- is a manual hand-set day/night or an optional auto dimming interior mirror.

The auto dimming interior mirror has two features:
- automatic dimming
- normal view state automatic lock-in when the vehicle is placed in R (reverse)

The automatic dimming feature darkens the interior mirror whenever the front ambient light sensor detects low outside light and glare reaches the light sensor (photo cell), which is located inside the interior mirror. The auto dimming interior mirror starts to return to the normal view once the glare goes away.

The exterior mirrors:
- are controlled by power controls on the LH front door trim panel.
- are of a foldaway design.
- may contain turn signal indicators.
- may be heated when the heated back window glass is activated.
- may have a programmable recall memory option.
- may have a reverse drive feature.

Driver Seat Module
The power driver seat and power exterior mirrors are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option.

The DSM system consists of the following components:
- driver seat module (DSM)
- driver memory seat switch
- memory mirror switch
- memory set switch
- front vertical seat motor
- rear vertical seat motor
- driver horizontal seat motor
- LH heated memory mirror
- RH heated memory mirror

The DSM incorporates multiple functions into one module and offers diagnostics to easily locate and repair concerns affecting the subsystems that it controls.

Power Exterior Mirror Operation
The power exterior mirrors are controlled by the DSM and are operational all the time, whether the ignition switch is on or off. Using the power exterior mirror switch, the driver can adjust the driver and passenger exterior mirrors four ways.

Up/Down Motion
The power exterior mirrors can be moved up and down under motor control by actuating the power mirrors UP/DOWN switch. The DSM will power the driver or passenger mirror up/down motor until the switch is released or until the travel limit is reached.

Left/Right Motion
The power exterior mirrors can be moved left and right under motor control by actuating the power mirrors LEFT/RIGHT switch. The DSM will power the driver or passenger mirror left/right motor until the switch is released or until the travel limit is reached.

Mirror Selection - Driver/Passenger
The driver can select the driver or passenger mirror to be adjusted by setting the mirror select switch to the appropriate position.

Turn Signal Mirror
The exterior mirror may be equipped with a mirror-mounted turn signal assembly. For Diagnosis and Testing, refer to Lighting and Horns.

Power Folding Mirrors
The power folding exterior mirrors are controlled by the power folding mirror switch. The power folding mirror switch has power at all times.

Memory Power Exterior Rear View Mirror Operation
The memory power exterior mirrors feature allows the driver to program personalized mirror positions that can be recalled using the memory switches or remote transmitter. There are three memory settings possible. The power driver seat positions are also stored, and recalled with the memory exterior mirrors positions.

Reverse Drive Rear View Mirror
The reverse drive rear view mirror function:
- tilts the exterior rear view mirror downward to improve the visibility in the rear bumper area.
- is operated by the driver seat module (DSM).
- is turned ON and OFF through the message center.

When the reverse drive rear view mirror function is enabled:
- The driver exterior rear view mirror tilts down three degrees and the passenger exterior rear view mirror tilts down five and a half degrees when the ignition switch is in RUN and REVERSE is selected.

The exterior rear view mirror will return to the original setting when the transmission is shifted out of reverse.
- Pressing the exterior rear view mirror control will cancel the reverse tilt or automatic mirror position return if it is operating.
- If the transmission is shifted out of REVERSE and then back into REVERSE within 10 seconds, the driver seat module will delay reverse tilt operation for 5 seconds.
