Trailer Brakes - Tesla X Owner's Manual

Towing a Trailer
• Smart Air Suspension does not make
automatic height adjustments based on
saved location-based settings.
• Side collision warnings are active but
automatic steering interventions are
disabled.
In addition, the braking force provided by
Automatic Emergency Braking (see
Avoidance Assist on page 95) is significantly
limited.
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 the
Park gear, or engaging the Neutral gear and
manually applying the parking brake using the
touchscreen (Controls > Driving > E-Brake &
Power Off > Parking Brake).
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 air suspension
setting to appropriately match the height
of the hitch with the height of the trailer.
You must choose a trailer hitch and trailer
that have the appropriate height for
suitable axle loading and trailer balance.
Warning: Do not use Trailer Mode when
attaching a bicycle carrier to the trailer
hitch (see Using a Bicycle Carrier
73).

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.
