Driving and Operating 9-79 Trailer Sway Control (TSC) Non-hybrid vehicles with StabiliTrak have a Trailer Sway Control (TSC) feature. If the vehicle is towing a trailer and the system detects that the trailer is swaying, the vehicle brakes are applied without the driver pressing the brake pedal. If the vehicle is equipped with the Integrated Trailer Brake Control (ITBC) system, StabiliTrak may also apply the trailer brakes. The TCS/ StabiliTrak warning light will flash on the instrument panel cluster to notify the driver to reduce speed. If the trailer continues to sway, StabiliTrak will reduce engine torque to help slow the vehicle. See StabiliTrak® System on page 9‑43 for more information. Adding non‐dealer accessories can affect the vehicle performance. See Accessories and Modifications on page 10‑3 for more information. Conversions and Add-Ons Add-On Electrical Equipment Notice: Some electrical equipment can damage the vehicle or cause components to not work and would not be covered by the warranty. Always check with your dealer before adding electrical equipment. Add-on equipment can drain the vehicle's 12-volt battery, even if the vehicle is not operating. The vehicle has an airbag system. Before attempting to add anything electrical to the vehicle, see Servicing the Airbag-Equipped Vehicle on page 3‑38 and Adding Equipment to the Airbag-Equipped Vehicle on page 3‑38. Adding a Snow Plow or Similar Equipment Before installing a snow plow on the vehicle, here are some things you need to know: Notice: If the vehicle does not have the snow plow prep package, adding a plow can damage the vehicle, and the repairs would not be covered by warranty. Unless the vehicle was built to carry a snow plow, do not add one to the vehicle. If the vehicle has the snow plow prep package, called RPO VYU, then the payload the vehicle can carry will be reduced when a snow plow is installed. The vehicle can be damaged if either the front or rear axle ratings or the Gross Vehicle Weight Rating (GVWR) are exceeded.
