It mayalso be necessary to turn off the system whendriving in extreme off-road conditions where highwheel spin is required. See If Your Vehicle isStuck in Sand, Mud, Ice, or Snow on page 364.Traction Control OperationThe traction control system is part of theStabiliTrak® system. Traction control limits wheelspin by reducing engine power to the wheels(engine speed management) and by applyingbrakes to each individual wheel (brake-tractioncontrol) as necessary.The traction control system is enabledautomatically when you start your vehicle, andit will activate and display the StabiliTrak® light ifit senses that any of the wheels are spinningor beginning to lose traction while driving.327
