Trailer Sway Message
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The message center provides the trailer sway message to inform the driver that the current traction control event is due to trailer sway. If the ABS module determines that the trainer is causing the vehicle to sway, the traction control/stability assist indicator is turned on along with the TRAILER SWAY REDUCE SPEED message in the message center.
