The brakes willautomatically release when theaccelerator pedal is applied withinthe two-second window. It will notactivate if the vehicle is in a drivegear and facing downhill, or if thevehicle is facing uphill and inR (Reverse).Ride Control SystemsTraction Control/Electronic StabilityControlSystem OperationThe vehicle has a Traction ControlSystem (TCS) and StabiliTrak ® , anelectronic stability control system.These systems help limit wheel slipand assist the driver in maintainingcontrol, especially on slippery roadconditions.TCS activates if it senses that anyof the drive wheels are spinning orbeginning to lose traction. When thishappens, TCS applies the brakes tothe spinning wheels and reducesengine power to limit wheel spin.StabiliTrak activates when thevehicle senses a difference betweenthe intended path and the directionthe vehicle is actually traveling.StabiliTrak selectively appliesbraking pressure to any one of thevehicle wheel brakes to assist thedriver in keeping the vehicle on theintended path. Trailer Sway Control(TSC) is also on automatically whenthe vehicle is started. See TrailerSway Control (TSC) on page 9-67.If cruise control is being used andtraction control or StabiliTrak beginsto limit wheel spin, cruise control willdisengage. Cruise control may beturned back on when roadconditions allow.Both systems come onautomatically when the vehicle isstarted and begins to move. Thesystems may be heard or felt whilethey are operating or whileperforming diagnostic checks. Thisis normal and does not mean thereis a problem with the vehicle.It is recommended to leave bothsystems on for normal drivingconditions, but it may be necessaryto turn TCS off if the vehicle getsstuck in sand, mud, ice, or snow.
