Vehicle stability management
(VSM) (if equipped)
This system provides further enhance-
ments 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 brak-
VSM operation
When the VSM is in operation, ESC indi-
cator 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 can be deactivated even if you
don’t cancel the VSM operation by press-

a malfunction has been detected some-
where in the Electric Power Steering sys-
tem 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.
The VSM is designed to function
above approximately 15 km/h (9 mph)
on curves.
The VSM is designed to function
above approximately 30 km/h (18
mph) when a vehicle is braking on a
split-mu road. The split-mu road is
made of surfaces which have different
friction forces.
The Vehicle Stability Management
system is not a substitute for
safe driving practices but a sup-
plementary 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 acti-
vate 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 inclement
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.
