Trailer Mode must always be active when towing a trailer. When you connect a trailer's electrical connection while the vehicle is in Park, Model Y automatically engages Trailer Mode. When you disconnect the trailer's electrical connection, Trailer Mode does not automatically disengage. To manually engage or disengage Trailer Mode, touch Controls > Pedals & Steering > Trailer Mode on the touchscreen. One of the following indicators displays:
Trailer Mode is active.
Model Y detects a connection for
trailer
lights but Trailer Mode is disabled. It is
likely that a carrying accessory has been
connected.
Model Y detects a faulty electrical
connection for the trailer lights. Some, or all, trailer lights may not be
functioning. Pull over as soon as safety permits and inspect the trailer lights
for faulty cabling or connections. If the issues are resolved and the red icon
still persists, disable and re-enable Trailer Mode once more.
Some Autopilot features (Autosteer, Summon, Lane Assist, etc.), as well as rear parking sensor functionality, may not be available when Trailer Mode is enabled. In addition, some features may operate differently. For example:
WARNING: Do not rely on Model Y to detect the trailer and automatically engage Trailer Mode. Always check that Trailer Mode is engaged before towing a trailer.
WARNING: Under no circumstances should you exit Trailer Mode when towing a trailer. Doing so can cause serious injury and/or death.
