Q: What indicates that the AdvanceTrac® with Roll Stability Control™ is active?

While you shouldn’t notice much when the AdvanceTrac® with Roll Stability Control™ activates, you may feel some sensations depending on what the system is doing and what the driving conditions are. Here’s what you should know:

During Self-Check

The traction control and stability system on your car will conduct a self-check when you first start the engine. It’s normal to hear a grinding or rumbling noise, as well as feel a slight movement in the brake pedal.

Active

When the traction and stability control system activates because of driving conditions, you may notice a number of different things, including the following:

• Vehicle slows down a little
• The TCS light on the dash may flash
• The brake pedal may vibrate
• The brake pedal may move on its own if you’re not pressing on it and serious driving conditions exist
• You may hear air from under the gauge cluster (this is normal)
• You may feel additional stiffness in the brake pedal
