Towing a Trailer
Trailer Brake Controller Limitations
WARNING: It is your responsibility to understand
your towing needs, proper towing procedures,
trailer brakes (such as their use and limitations),
and the risks and limitations of towing. Do not tow
with Cybertruck if you do not have towing
knowledge and experience; doing so may result in
damage, injury or death. Damage as a result of
improper towing is not covered by the warranty.
Keep in mind the following brake controller limitations:
• Properly maintain and use trailer brakes as intended
to prevent damage.
• The trailer brake controller and auxiliary output is 12V.
• Abusive or extensively long manual activations of the
trailer brake controller may cause overheating with
some trailer brake loads.
• Maximum power draw - The onboard trailer controller
is designed to support most trailer power
applications. The power allocations are:
Standard trailer brakes
(when braking power is
derived from brake output,
e.g. non-EOH Electric Drum
brakes)
Electric over Hydraulic trailer
brakes (braking power is
derived from auxiliary power
output, e.g. EOH, Hydraulic
disk brakes, see Electric Over
Hydraulic (EOH) Brakes on
page 108)
Cybertruck switches to the standard brakes if a 3A
or higher load on the trailer brake connections is
detected.

Electric Over Hydraulic (EOH)
Brakes
Cybertruck supports standard electric brakes and
Electric over Hydraulic (EOH) brakes. If using EOH
brakes, Tesla recommends connecting a battery in
parallel with the auxiliary power output to the EOH unit.
The auxiliary output is capable of supplying up to 30
Amps when supporting an EOH trailer brake unit. You
are responsible for understanding the power needs of
your EOH trailer brake unit. Using an EOH trailer brake
controller that draws more than 30 Amps may result in a
loss of power to the trailer brakes while braking.
The usage of only an EOH unit with the auxilary power
port is supported for maximum braking availability. A
battery in parallel is recommended. The battery must be
in good health and is expected to already be present in
most states per DOT regulations.
