Note
- There is currently no child lock-out feature planned for the Rear A/C Display Control Head -E265- (introduction not yet finalized). If the child safety system for the Rear A/C Display Control Head -E265- is offered in the future and is active in the vehicle, the setting of the rear A/C system and the seat heating cannot be changed by the Rear A/C Display Control Head -E265- (when a button or knob is operated, three lines appear in both displays). The settings can then only be modified via the Front A/C Display Control Head -E87- and the MMI Terminal. Refer to the Operating Instructions.
- On a vehicle with a "Mid" or "Mix" A/C system the Rear A/C Display Control Head -E265- exchanges information via the LIN bus with the Front A/C Display Control Head -E87-. Refer to Vehicle Diagnostic Tester in the "Guided Fault Finding" function and refer to → Wiring diagrams, Troubleshooting & Component locations.
- On a vehicle with a "High" A/C system the Rear A/C Display Control Head -E265- exchanges information via the data bus with the Front A/C Display Control Head -E87-. Refer to Vehicle Diagnostic Tester in the "Guided Fault Finding" function and refer to → Wiring diagrams, Troubleshooting & Component locations.
- When replacing the Rear A/C Display Control Head -E265-, ensure correct allocation with respect to the Front A/C Display Control Head -E87-. If the allocation is incorrect, various functions of the rear A/C system, for example, may not be able to be displayed and selected. Refer to the Parts Catalog.
- Certain A/C system functions can be switched on and off via the MMI (Multi Media Interface) in the "A/C system" function under the "Car"/"Vehicle" menu. The A/C system control can also be influenced via the presets in the MMI (Multi Media Interface) under the "A/C system" function in the "Car"/"Vehicle" menu. Therefore, check the preset in the MMI first in the case there is a problem with these components. Refer to Infotainment/MMI Operating Instructions.
