Principle of Operation

Electronic Stability Control

WARNING   WARNING:  The system is designed to aid the driver. It is not intended to replace your attention and judgment. You are still responsible to drive with due care and attention.

 

The system supports stability when your vehicle starts to slide away from your intended path. The system does this by braking individual wheels and reducing engine torque.

The system also provides an enhanced traction control function by reducing engine torque if the wheels spin when you accelerate. This helps to pull away on slippery roads or loose surfaces, and improves comfort by limiting wheel spin in hairpin bends.
