NOTE: It is the driver's responsibility to ensure that all
electrical connections are working and all trailer lights
are operating before and during towing. You must
perform manual checks.
NOTE: Loss of trailer lights when towing may be the
result of a fault in the trailer wiring or excessive power
consumption by the lights connected to the trailer
output(s). When this occurs, a red Trailer Mode icon
appears on the touchscreen. Fix any issues with the
wiring and/or reduce the number of lights connected to
the trailer output(s), then toggle Trailer Mode off and on
again.
CAUTION: Always ensure that the trailer electrical
cable does not contact or drag on the ground and
there is enough slack in the cable to allow for
turns.
WARNING: Use only the electrical connections
designed by Tesla. Do not attempt to directly
splice or attempt to connect a trailer's electrical
wiring using any other method. Doing so can
damage the vehicle's electrical system and cause
malfunctions.

Impact on Range
Towing a trailer increases vehicle weight and drag. As a
result, driving range can decrease significantly. Although
Trip Planner (if available in your market region) attempts
to adjust estimates based on Trailer Mode, actual energy
consumption may vary. Plan trip length and charging
destinations accordingly.
