M21/1 | Driver-side outside mirror |
M21/2 | Passenger-side outside mirror |
P88.70-2869-76
Location
The outside mirrors are installed externally at the front on the front doors.
Task
The outside mirrors allow for a view on the traffic at the side behind the vehicle and warn, depending on the equipment, of objects in the blind spot. The outside mirror housing has been designed so that the aerodynamic drag, wind noises and impairments of the field of vision due to fogging and contamination are minimized.
The electric motors and the components integrated in the mirror glass are actuated by the respective front door control unit.
Structure
The outside mirrors include the following components:
Outside mirror housings
Mirror glass
Mirror glass heater
The mirror glass heater consists of a conductor track on the rear of the mirror glass. When a voltage is applied, this conductor track heats up due to the electrical resistance. The mirror glass can thus be defrosted or a fogging up of the mirror glass can be counteracted.
Mirror glass dimming (vehicles with automatic anti-dazzle mirrors and only on the driver's side)
The dimming or darkening of the mirror glass is realized by an electrolyte gel layer between the reflector and glass cover. This layer contains electrolytes consisting of uniform crystals, similar to a LCD display. Depending on the applied voltage, these crystals align themselves in a specific angle and thus influence the light transmission.
Mirror glass mechanical components
Vertical inclination adjustment actuator motor
Vertical inclination adjustment potentiometer (vehicles with memory function)
Horizontal inclination adjustment actuator motor
Horizontal inclination adjustment potentiometer (vehicles with memory function)
Fold-back motor (vehicles with electric foldable outside mirrors)
Components of other functions can also be accommodated in the outside mirror housing and mirror glass. This includes:
Turn signal lamp
Blind Spot Assist warning display (vehicles with Blind Spot Assist)
The Blind Spot Assist warning display consists of a LED integrated in the mirror glass.
Ambient lamp (vehicles with mirror package)
Camera for 360° camera (vehicles with Parking Package and/or with 360° camera)
Telephone antenna (vehicles with car telephony)
GPS antenna (vehicles with navigation system)
