1. Go to Advanced Settings > Custom Buttons.
2. Follow the on-screen instructions to assign your desired key combinations.

1. Navigate to Advanced Settings > Learning Mode > Enter Learning Mode to add a new phone.
2. Reset the Bluetooth password via Change Password for added security.

Q: What is Maintenance Mode?
A: Maintenance Mode temporarily disables phone detection, useful for car washes or servicing:

1. Enable it under Advanced Settings > Switching Mode > Maintenance Mode.
2. The vehicle can then lock/unlock and start without phone detection.

Q: Can the emergency key inside the device be used for starting?
A: No. The physical emergency key is restricted for security and cannot be used directly, even if removed.
