Tesla Model Y Owners & Service Manuals

Tesla Model Y: Trailer Mode

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:

  • Traffic-Aware Cruise Control increases the following distance from the car in front of you.
  • Side collision warnings are active but automatic steering interventions are disabled.
  • The braking force provided by Automatic Emergency Braking (see Collision Avoidance Assist) is significantly limited. Therefore, stopping distance may increase.

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.

     Adjusting Second Row Seat Backs

    Model Y provides seating for up to three passengers in the second row. The seat back is split 60/40 so adjusting the left seat back moves the seat backs for both the left and center seating positions, whereas adjusting the right seat back moves only the rightmost seat back.

     Limitations and Inaccuracies

    Lane Assist features cannot always detect lane markings and you may experience unnecessary or invalid warnings in these situations: Visibility is poor and lane markings are not clearly visible (due to heavy rain, snow, fog, etc.). The exact detection zone of the ultrasonic sensors varies d
