TSA (Trailer Stability Assist) Features
WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
While towing a trailer, factors, such as a lane change, inappropriate tongue weight, and crosswind, can cause trailer sway. This may also cause the vehicle to sway. The trailer stability assist helps stabilize the vehicle, using the same system as VSA (VSA modulator-control unit and sensors). With signals from each sensor, the trailer stability assist detects when trailer sway affects the vehicle, and then reduces vehicle speed while stabilizing the vehicle. The rear brake lights automatically turn on when the trailer stability assist activates.
