Warnings and Safety Instructions | 5
8. During the calibration step of the Tow‑Pro®Liberty, braking of the trailer may be inconsistent. REDARC
recommends calibrating the Tow‑Pro®Liberty without a trailer attached. A normal drive of a few miles
will do for this purpose. If calibrating with a trailer attached, then the recommended dial setting for the
Tow‑Pro®Liberty is 4 or less.
NOTICE
1. Ensure that a correct grounding point is used. Vehicles often have ungrounded metal reinforcements
under the dash and these points are not suitable grounds. Bad grounding of the unit will result in poor or
no operation.
2. The Tow‑Pro®Liberty does not act as a trailer lights voltage converter. If the trailer brake lights operate
on a different voltage, damage to the vehicle; trailer and/or Tow‑Pro®Liberty and associated wiring may
result. This may also result in reduced (or total loss of) trailer braking.
3. When installing the Tow‑Pro®Liberty Remote Control to a thin panel, washers are recommended to
reinforce the structure of the panel.
4. Do NOT exceed Tow Vehicle and Trailer weights and specifications. Failure to abide by the towing
regulations, including maximum loads, may result in a fine, or in case of an accident, refusal of the
insurance claim, and the possibility of further legal action.
If the tow vehicle or trailer’s maximum load is exceeded, police and transport authorities have the power
to order the combination off the road until the issue is corrected. This may necessitate leaving the trailer
on the side of the road while a vehicle with suitable towing capacity is sourced or the trailer load is
reduced. Please contact your local authorities for further information.
5. If no trailer is connected, Active Calibration may occur as normal without any indication from the LED. The
LED will already be Blue when the trailer is connected. Essentially, whether a trailer is connected or not,
just drive normally and Active Calibration will ensure the Tow‑Pro®Liberty learns the correct direction of
travel.
6. The State of California regulations require that the manual override function illuminates the trailer brake
lights. Once the Tow‑Pro®Liberty is installed it should be tested with your vehicle to confirm the wiring
configuration to make sure the brake lights are illuminated when the override button is pressed.
