Kia Soul: Vehicle stability management (VSM)
This system provides further enhancements to vehicle stability and steering responses when a vehicle is driving on a slippery road or a vehicle detects 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.
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:
- Driving on bank road such as gradient or incline
- Driving in reverse
- ESC OFF indicator light (
) remains on the instrument cluster
- EPS indicator light remains on the instrument cluster
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 (
) 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 don’t 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
(
) or EPS warning light remains on, take your vehicle to an authorized Kia dealer
and have the system checked.
✽ NOTICE
- The VSM is designed to function above approximately 13 mph (22 km/h) on curves.
- The VSM is designed to function above approximately 6 mph (10 km/h) when a vehicle is braking on a split-mu road. The split-mu road is made of surfaces which have different friction forces.
WARNING
- The Vehicle Stability Management system is not a substitute for safe driving practices but a supplementary function only. It is the responsibility of the driver to always check the speed and the distance to the vehicle ahead. Always hold the steering wheel firmly while driving.
- Your vehicle is designed to activate according to the driver’s intention, even with installed VSM. Always follow all the normal precautions for driving at safe speeds for the conditions – including driving in clement weather and on a slippery road.
- Driving with varying tire or wheel sizes may cause the VSM system to malfunction. When replacing tires, make sure they are the same size as your original tires.
