Volkswagen ID.4: Hitching a trailer

Trailer socket

The Volkswagen ID.4 connects electrically to a trailer via a standardized 13-pin trailer socket. The pin configuration complies with DIN ISO 11446, ensuring compatibility with most modern trailers and towing equipment.

If your trailer is equipped with a 7-pin connector, you will need to use a suitable adapter to ensure proper functionality with the Volkswagen ID.4.

1. Lift the protective cap on the trailer socket and insert the trailer plug.

2. Turn the plug clockwise by approximately a quarter turn until it locks securely into place.

3. Release the socket cap to secure the connection.

4. Before driving, always verify that all trailer lights and electrical systems are functioning correctly.

If you are unsure about correctly connecting the electrical system of your trailer to the Volkswagen ID.4, consult an authorized Volkswagen dealer or service facility for assistance. Volkswagen strongly recommends professional installation and inspection.

Integrating into the anti-theft alarm system

The trailer can be integrated into the anti-theft alarm system of the Volkswagen ID.4 if the following conditions are met:

✓ The vehicle is equipped with a factory-installed anti-theft alarm system and original trailer hitch.

✓ The trailer is properly connected to the electrical system of the Volkswagen ID.4.

✓ Both the vehicle and trailer electrical systems are fully functional and undamaged.

✓ The vehicle has been locked using the key or keyless system and the alarm is activated.

When these conditions are fulfilled, disconnecting the trailer will trigger the alarm system.

Trailers equipped with LED tail lights may not be fully compatible with this feature due to their electrical characteristics.

In such cases, disconnecting the trailer may not activate the anti-theft alarm system.

WARNING

Incorrectly connected electrical systems in the Volkswagen ID.4 can lead to electrical faults, system malfunctions, and potentially serious accidents or fatal injuries.

• All work on the electrical system should be carried out only by qualified professionals or authorized Volkswagen service centers.
• Never connect the trailer wiring directly to the vehicle's lighting circuits or other power sources.

WARNING

Contact between the pins in the trailer socket can result in short circuits, electrical overload, or lighting failures, increasing the risk of accidents.

• Never allow the pins in the trailer socket to touch each other.
• Have damaged or bent pins repaired only by an authorized Volkswagen dealer or service facility.

NOTICE

If a trailer remains coupled to the Volkswagen ID.4 while supported by its jockey wheel or support stand, changes in load distribution or tire pressure may cause stress on the hitch system. This can result in damage to both the vehicle and the trailer.

• Do not leave the trailer attached to the Volkswagen ID.4 while it is resting on a support wheel or stand.

If the vehicle is switched off while the trailer remains electrically connected and its accessories are active, the 12 V battery of the Volkswagen ID.4 may discharge.

To protect the system, the Volkswagen ID.4 automatically disconnects the electrical connection if the 12 V battery charge level becomes too low.
