Volkswagen ID.4: Hitching a trailer

Trailer socket

The towing vehicle and the trailer are connected electrically using a 13-pin trailer socket. The pin assignment conforms to DIN ISO 11446.

If the trailer has a 7-pin connector, a suitable adapter must be used.

1. Lift the socket cap and insert the plug.

2. Rotate the plug clockwise by a quarter of a rotation until it fully engages into the socket.

3. Release the cap to lock the plug in place.

4. Check that the entire lighting system is working properly before starting the journey.

If you are not sure how to connect the trailer with the towing vehicle's electrical system correctly, consult an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

Integrating into the anti-theft alarm system

The trailer is integrated into the anti-theft alarm system if the following requirements are met:

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

✓ If the trailer is connected to the electrical system in the towing vehicle.

✓ If the vehicle and trailer electrical systems are functioning correctly and are not damaged.

✓ If the vehicle was locked using the vehicle key and the anti-theft alarm system is active.

When the vehicle is locked, the alarm will be triggered if the electrical connection to the trailer is disconnected.

Trailers with LED taillights cannot be integrated into the anti-theft alarm system due to the technology involved.

When the vehicle is locked, the alarm will not be triggered if the electrical connection to the trailer with LED taillights is disconnected.

WARNING

Improperly or incorrectly connected electrical wires can electrify the trailer and lead to malfunctions in the entire vehicle electrical system as well as accidents and serious injuries or death.

• Have all work on the electrical system performed only by an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
• Never connect the electrical system on a trailer to the electrical connectors for the taillights or other power sources on the towing vehicle.

WARNING

Contact between the pins on the trailer socket can cause short circuits, overloading of he electrical system or malfunction of the lighting system, which can result in accidents and serious injuries or death.

• Never connect the pins in the trailer socket to one another.
• Have bent pins repaired only by an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

  Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

NOTICE

If a trailer hitched to the vehicle is resting on a supporting wheel or on the trailer support, the vehicle may lift and lower due to changes in the load or tire damage. This would put great stress on the trailer hitch and the trailer. This can cause damage to the vehicle and trailer.

• Note that a trailer that is resting on a supporting wheel or on the trailer support should not remain hitched to the vehicle.

If the engine is stopped and accessories on the trailer are on while there is an electrical connection through the trailer socket, then the 12 V vehicle battery will drain.

The electrical connection to the trailer will be automatically disconnected if the charge level of the 12 V vehicle battery becomes too low.
