Do not attempt to directly splice the cables or connect the trailer’s cable by any other method, as this could damage the vehicle’s electrical system and cause fault.
Caution • Before and during towing, you need to manually check and ensure that all electrical connections are working properly and all trailer lights are working correctly. • Trailer light failure during towing may be the result of a blown fuse. If the fuse is blown, there will be no warning from your vehicle. Please contact the NIO Service Center. • Make sure that the trailer cable does not touch or drag on the ground during towing, and that the cable has enough slack to allow for turns. 109
