TRAILER SWAY ASSIST

While pulling a trailer, certain road, weather, and/or trailer load conditions may cause swaying (oscillation) between the trailer and the towing vehicle. The 2016 TITAN XD can be equipped (depending on specific model and selected options) with Trailer Sway Assist, which operates as part of the Vehicle Dynamic Control (VDC).

NOTE:
  • VDC is standard on all 2016 TITAN XD vehicles. Trailer Sway Assist is available depending on specific model and selected options.
  • When towing a trailer, always follow the towing information in the vehicle Owner’s Manual and information supplied by the trailer manufacturer.
Trailer Sway Assist:
  1. Trailer Sway Assist is a function of the Vehicle Dynamic Control (VDC) system and is active when the VDC is turned ON.
  2. When trailer sway (oscillation) is detected, based on input signals to the ABS actuator and electric control unit, trailer stability is improved by brake force control on all four wheels and engine output control of the towing vehicle.
  3. When Trailer Sway Assist operates, the VDC warning light blinks. When vehicle control is regained, the VDC warning light will turn OFF.
  4. Sounds may be heard or slight vibrations may be felt through the brake pedal and operation noises may occur (similar to ABS functioning) when Trailer Sway Assist functions. This is normal.

To reduce and minimize trailer sway (oscillation), brake force (brake fluid pressure) is applied to the wheels as needed. Brake force is applied to individual wheels (1, 2, 3, or all 4) as conditions require to reduce and minimize trailer sway.

If Trailer Sway Assist activates, do the following:
  1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer as straight ahead as the road conditions allow. This combination will help stabilize the vehicle.
  2. When the trailer sway stops, gently apply the brakes and pull to the side of the road in a safe area.
  3. Try to rearrange the trailer load so it is balanced. Refer to the Owner’s Manual for trailer loading information.
