Allocating Radio Frequency Remote Control Key To Memory Buttons
After storing the seat and mirror settings there is a 10 second period where the radio frequency remote control key can be allocated to the appropriate memory button.
The number of the radio frequency remote control key will be transferred from the comfort system central control module via the CAN-bus to the memory control module.
- Pull the radio frequency remote control key out of the ignition lock.
- Press the open button of the radio frequency remote control key and hold it depressed for at least 1 second until an acoustic signal confirms the allocation.
The settings are stored under the selected memory button.
NOTE:
- If the remote control key was previously allocated to a different memory button, the old allocation will be erased.
- If the radio frequency remote control key is allocated to a memory button to which another key is already allocated, the old allocation will also in this case be erased.
- The allocation of a radio frequency remote control key to a memory button will be retained even when new seat and mirror settings are stored on this button.
- When the vehicle battery is disconnected all allocations for radio frequency remote control keys to the memory buttons will be erased.
- For future versions of the control module this data will be retained even when the battery is disconnected.
