Trailer Mode
Trailer Mode must always be active when
towing a trailer. When you connect a trailer's
electrical connection, Model X automatically
engages Trailer Mode. When you disconnect
the trailer's electrical connection, Trailer Mode
disengages. To engage or exit Trailer Mode
manually, touch Controls > Driving > Trailer
Mode on the touchscreen. One of the
following indicators display on the instrument
panel:
Trailer Mode is active.
Model X detects a connection for
trailer lights but Trailer Mode is
disabled. It is likely that a carrying
accessory has been connected.
Model X 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, turn Trailer Mode off and on
again.
Note: In situations where Model X detects a
heavy load, it assumes that a trailer is
connected and automatically engages Trailer
Mode. A message displays on the instrument
panel informing you that Trailer Mode has
been engaged. When Trailer Mode is entered
automatically due to detection of a heavy
load, you can change the Trailer Mode setting
only by stopping Model X and engaging Park
or engaging Neutral and manually applying
the parking brake using the touchscreen
(Controls > Driving > E-Brake & Power Off >
Parking Brake).
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,
these features operate differently:
• Traffic-Aware Cruise Control increases the
following distance from the car in front of
you.
• The air suspension system will not make
speed-based adjustments from
STANDARD to LOW.
Driving
Towing and Accessories
• The air suspension system does not
automatically raise ride height based on
saved locations.
• Side collision warnings are active but
automatic steering interventions are
disabled.
• The braking force provided by Automatic
Emergency Braking (see
Avoidance Assist
significantly limited.
Warning: Do not rely on Model X 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.
Warning: Do not use the suspension
setting to appropriately match the height
of the hitch with the height of the trailer.
Trailer Brakes
When towing a loaded trailer that weighs
more than 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.
