WARNING:
Towing increases your
stopping distance, even when the
trailer is equipped with its own
braking system. When towing,
increase your following distance and
avoid situations that could potentially
cause heavy braking. Failure to do so
can result in a collision.
WARNING:
Observe all regulations
and legal requirements in your
regional and national jurisdictions that
apply specifically to trailer towing and
brake requirements. Many regions
require a breakaway switch, located
on the tongue of the trailer, to activate
the trailer brakes in the event that the
trailer separates from the vehicle.
Failure to comply with regulations can
compromise your safety.
WARNING:
Follow the instructions
provided by the trailer brake
manufacturer to ensure that trailer
brakes are properly installed, adjusted,
and maintained. Tesla is not
responsible for damages caused by
incorrect installation of trailer braking
systems.
WARNING:
Never attempt to connect
trailer brakes directly to the vehicle
braking system. Doing so can cause
damage to the vehicle and the trailer,
and can cause the braking system to
malfunction, resulting in serious injury
or death.
