Helps stabilize the vehicle and trailer when the trailer severely sways.

1. Trailer stability assist is not a function that prevents the vehicle and trailer from swaying. Avoid high speeds, abrupt steering, improper trailer load, and sudden braking to keep the trailer from swaying. When swaying too severely, the system becomes ineffective, and you may lose control of your vehicle, causing the trailer to roll over or get damaged.

   How trailer stability assist works 

2. Trailer towing sway is caused by crosswinds, improper tongue load, and/or excessive speed.

When the vehicle and trailer become unstable while driving, trailer stability assist determines the cause. If the trailer oscillation is detected as the cause, and the swaying increases, the system applies the brakes or controls engine output to reduce vehicle speed.

Both the vehicle and trailer brake lights come on automatically if you brake to reduce vehicle speed.

The VSA® system indicator blinks during the trailer stability assist operation.
