INTRODUCTION
Movement of the door mirrors is controlled from a switch pack located on the drivers door. The switch pack contains 2 non-latching mirror select buttons labelled 'L' and 'R' and a 4-way mirror movement switch. Door mirror movement commands are transmitted to the driver's door module over the LIN (local interconnect network) bus. The drivers door module transmits any mirror movement commands to the passenger door module over the medium speed CAN (controller area network) bus.
Movement of the door mirrors is carried out by the respective door module. The door modules provide supply and ground paths to the mirror motors and monitor mirror position via potentiometers located in the mirror housings.
An electrochromic interior mirror is mounted on the windshield and contains a forward and a rearward facing light sensor. The light sensors control the auto dimming feature of the interior mirror to reduce glare from the headlights of following vehicles.
When auto-dimming of the interior mirror is required, a supply is provided by the interior mirror to both door mirrors to initiate the door mirror auto-dimming sequence.
Some vehicles may be fitted with an interior mirror featuring an electronic compass with LED (light emitting diode) display. The compass is a self contained unit and does not interface with any other vehicle system or electronic control module. Details of how to set and calibrate the compass can be found in the 'Mirrors' section of the Owner's Handbook.
Up to 2009 Model Year (MY), some vehicles have door mirrors with an electric foldback feature. From 2009 MY, the mirror foldback feature is a standard fit in all markets. Where fitted, mirror foldback can be operated manually or automatically.
Manual operation of mirror foldback is initiated with the vehicle stationary or moving at 20 km/h (12 mph) or less, by pressing then releasing the L and R mirror select buttons at the same time. The first press of the mirror select buttons causes the two door mirrors to turn inwards to the folded position and stop. A further press of the mirror select buttons causes the door mirrors to turn outwards to the unfolded position and stop. If the mirror select buttons are pressed while the door mirrors are moving, they stop and reverse direction until they reach their original position. If one of the door mirrors has been manually folded, the two door mirrors can be re-synchronized by an inward and outward operating cycle.
Automatic mirror foldback is selected and deselected on the vehicle settings menu of the Touch Screen Display (TSD). Automatic operation is synchronized with the exterior locking and unlocking of the vehicle (it does not work with interior locking and drive away locking). If automatic operation is selected, the door mirrors fold when the vehicle is locked and unfold when unlocked. However, the door mirrors will not unfold automatically if they have been folded manually, even though automatic mode is selected on the TSD.

A thermal cut-out feature is incorporated to protect the mirror foldback motors. Thermal cut-out only occurs with the door mirrors in the unfolded position, and resets after 5 minutes.
