Only attach appropriate electrical connectors, which are in good condition, to the trailer socket. Using inappropriate towing equipment may adversely affect the accuracy and performance of the vehicle's towing features.


Only use electrical equipment that requires a 12 volt supply from the vehicle.

When a trailer's electrical connection is made and the vehicle’s turn signals are used, the trailer warning indicator flashes in time with the turn signals. See TRAILER TURN SIGNALS (GREEN).

In the event that the vehicle's turn signals are used and the symbol does not flash, the trailer's connection should be checked. Take appropriate action to make sure that the trailer's turn signals are functioning correctly.

The information in the following table helps to confirm if a trailer or a lighting board is compatible for use with this vehicle. If these conditions are not met, the vehicle will not detect the electrical connection of a trailer or a lighting board.
