Mirrors: Description and Operation: Overview

Rear View Mirrors

Overview
The exterior mirrors incorporate the following:
- Blind spot monitoring indicator
- Auto dimming function
- Turn signal indicators
- Approach lamps
- Exterior temperature sensor
- Heated mirror function
- Reverse dipping function
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 labeled '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.
Both exterior door mirrors and the interior mirror feature an auto dimming function. The interior rear view mirror contains one forward and one reward 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.
Blind spot monitoring function alerts the driver to a vehicle located in the vehicle blind spot. A warning indicator is located in each exterior mirror towards the outer edge.
