Under no circumstances should you
exit Trailer Mode when towing a trailer. Doing so
can cause serious injury and/or death.

Trailer Brakes
When towing a loaded trailer that weighs more than
1000 lbs (450 kg), Tesla recommends that the trailer be
equipped with its own brake system adequate for the
weight of the trailer. Ensure compliance with local
regulations. A brake controller must be purchased
separately, and the required 4-pin pigtail connector can
be ordered from Tesla Service.
Follow these steps to connect a brake controller:
1. Connect the wiring on the brake controller to the
appropriate locations on the 4-pin pigtail connector.
1 - Brake control output to trailer
2 - Ground
3 - Brake On Signal
4 - Low Voltage Power (20A)
2. Remove the cover located under the dashboard in
the driver's side foot well.
