9-40 Driving and Operating Engine Drag Control (EDC) EDC improves vehicle stability by sensing if there is a difference in speed between the free rolling front wheels and the rear drive wheels that often occurs when the driver takes their foot off the accelerator pedal on slippery surfaces (snow, ice, etc.). When this is detected, EDC sends more torque to the rear wheels to make sure all four wheels are spinning at similar speeds, making the vehicle more stable. If there is a problem detected with StabiliTrak, a SERVICE STABILITRAK message displays on the DIC and the StabiliTrak/TCS warning light on the instrument panel cluster comes on. When this message and warning light display, the system is not operational. Driving should be adjusted accordingly. See Ride Control System Messages on page 5‑39 and Traction Control System (TCS)/StabiliTrak® Light on page 5‑22 for more information. StabiliTrak comes on automatically whenever the vehicle is started. The system should be left on to help assist with directional control of the vehicle. If StabiliTrak needs to be turned off, press and hold the TCS/ StabiliTrak button until the Traction Control Off light and the StabiliTrak Off light come on in the instrument panel cluster. If the system has been turned off, press and release the TCS/StabiliTrak button to turn the system back on.
