Kia Optima: VSM (Vehicle stability management) - Driving your vehicle - Kia Optima TF 2011-2020 Owners ManualKia Optima: VSM (Vehicle stability management)

This system provides further enhancements to vehicle stability and steering responses when a vehicle is driving on a slippery road or a vehicle detected changes in coefficient of friction between right wheels and left wheels when braking.

VSM operation

When the VSM is in operation, ESC indicator light (blinks.) blinks.

When the vehicle stability management is operating properly, you can feel a slight pulsation in the vehicle and/or abnormal steering responses (EPS). This is only the effect of brake and EPS control and indicates nothing unusual.

The VSM does not operate when:

VSM operation off

If you press the ESC OFF button to turn off the ESC, the VSM will also cancel and the ESC OFF indicator light (To turn on the VSM, press the button again. The ESC OFF indicator light goes) illuminates.

To turn on the VSM, press the button again. The ESC OFF indicator light goes out.

Malfunction indicator

The VSM can be deactivated even if you donТt cancel the VSM operation by pressing the ESC OFF button. It indicates that a malfunction has been detected somewhere in the Electric Power Steering system or VSM system. If the ESC indicator light (take your vehicle to an authorized Kia dealer and have the system checked.) or EPS warning light remains on, take your vehicle to an authorized Kia dealer and have the system checked.
