The Service StabiliTrak system is crucial for keeping your GMC Yukon safe on the road. It helps you maintain control during skids or slides. Below, you’ll find more about the system’s essentials, how it works with traction control, and GMC’s dedication to safety.
Basics of StabiliTrak and ESC
StabiliTrak is GM’s proprietary Electronic Stability Control (ESC) system. It is designed to prevent skidding and loss of control. When the system detects you may be losing control, it adjusts power and brakes to individual wheels.
Unlike basic traction control, StabiliTrak uses sensors to monitor steering wheel position and vehicle direction. Its goal is to match these two as closely as possible. If there’s a mismatch, it kicks in automatically.
The system cooperates with the Anti-lock Braking System (ABS) to ensure a smooth application of brakes on individual wheels. This is essential to maintaining control during any driving condition. Overall, StabiliTrak adds a layer of safety, giving you confidence behind the wheel.
How Traction Control Complements StabiliTrak
Traction Control, or TCS, works in tandem with StabiliTrak. While StabiliTrak focuses on car direction and stability, TCS is about preventing wheel spin. It ensures the wheel that gets power can grip the road.
Traction control engages when sensors detect the wheels are losing traction. It might reduce engine power or apply brakes to help regain traction. This function is especially important when you encounter slippery roads or loose surfaces.
Together, StabiliTrak and Traction Control create a robust system that protects you in various situations. This combination better ensures safe driving, even when conditions become challenging.
