Driving your vehicle
• The HAC does not operate when the
transaxle shift lever is in the P (Park) or
N (Neutral) position.
• The HAC activates even though the
ESC is off but it does not activate when
the ESC has malfunctioned.
Vehicle stability management
(VSM)
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-
ing.
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 does not operate when:
• Driving on bank road such as gradient
or incline
• Driving rearward
• 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 (
) illumi-
nates.
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 press-
ing the ESC OFF button. It indicates that
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.
