Trunk Lid Position Setting: The trunk lid may be programmed to open to a specific height, such as halfway. This feature can be adjusted through the vehicle's settings or by using the trunk button.
Load-Assist Function: Some Mercedes CL 500 models feature a load-assist function that allows the trunk lid to open halfway and then stop, making it easier to load and unload items without fully opening the trunk. This function can be activated by pressing the trunk button twice.
Obstruction or Blockage: If the trunk lid encounters an obstruction or blockage while opening, it may automatically stop at the halfway point to prevent damage. Check for any obstacles or items blocking the trunk's opening path and remove them before attempting to open the trunk again.
Malfunctioning Trunk Lid Components: Issues with the trunk lid struts (gas springs), hinges, or control modules could lead to the trunk opening only halfway. These components are responsible for raising, holding, and lowering the trunk lid, so any mechanical or electrical malfunctions can affect their function.
Electrical Issues: Faulty wiring, loose connections, or problems with the trunk release switch can also cause the trunk lid to behave abnormally. Check the wiring harness and other electrical components associated with the trunk operation to identify any issues.
If the trunk lid of your Mercedes CL 500 continues to open halfway without an apparent reason or persists after removing obstructions or troubleshooting the settings, it's recommended to consult a professional mechanic or an authorized Mercedes-Benz service center for further diagnosis and repair.
