Tow Ball Arm Guidelines
- Replacement keys are available. We recommend that you record the key number on the lock cylinder.
- Keep the system clean. Periodically lubricate bearings, sliding surfaces and locking balls with resin-free grease or oil. Lubricate the lock with graphite.
- Remove the trailer wiring plug from the trailer wiring connection socket when not in use. Failure to do so may result in corrosion of the trailer wiring connection socket. Clean the trailer wiring connection socket regularly and make sure the socket cover is fully closed.
- If you use a high pressure water jet to clean your vehicle, disconnect the trailer wiring plug. Do not aim the water jet directly at the trailer wiring connection socket. We recommend that you detach the tow ball arm before washing your vehicle.
