Electronic stability control
(ESC)
The Electronic Stability control
(ESC) system is designed to stabi-
lize the vehicle during cornering
maneuvers. ESC checks where you
are steering and where the vehicle is
actually going. ESC applies the
brakes on individual wheels and
intervenes with the engine manage-
ment system to stabilize the vehicle. Electronic stability control (ESC) will
not prevent accidents. Excessive
speed in turns, abrupt maneuvers and
hydroplaning on wet surfaces can still
result in serious accidents. Only a
safe and attentive driver can prevent
accidents by avoiding maneuvers that
cause the vehicle to lose traction.
Even with ESC installed, always fol-
low all the normal precautions for driv-
ing - including driving at safe speeds
for the conditions.
The Electronic Stability Control (ESC)
system is an electronic system
designed to help the driver maintain
vehicle control under adverse condi-
tions. It is not a substitute for safe driv-
ing practices. Factors including speed,
road conditions and driver steering
input can all affect whether ESC will be
effective in preventing a loss of control.
It is still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.
When you apply your brakes under
conditions which may lock the wheels,
you may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensa-
tion in the brake pedal. This is normal
and it means your ESC is active.
✽ ✽
NOTICE
A click sound may be heard in the
engine compartment when the vehi-
cle begins to move after the engine is
started. These conditions are normal
and indicate that the Electronic
Stability Control System is function-
ing properly.
OJF055023WARNING
For maximum protection, always
wear your seat belt. No system,
no matter how advanced, can
compensate for all driver error
and/or driving conditions.
Always drive responsibly.

ESC OFF usage
When driving
ESC should be turned on for daily
driving whenever possible.
To turn ESC off while driving, press the ESC OFF button while driving
on a flat road surface.
✽ ✽ NOTICE
• When operating the vehicle on a
dynamometer, ensure that the
ESC is turned off (ESC OFF light
illuminated). If the ESC is left on,
it may prevent the vehicle speed
from increasing, and result in false
diagnosis.
• Turning the ESC off does not affect ABS or brake system opera-
tion.
Vehicle stability management
(VSM)
This system provides further
enhancements to vehicle stability
and steering responses when a vehi-
cle is driving on a slippery road or a
vehicle detects changes in coeffi-
cient of friction between right wheels
and left wheels when braking.
WARNING- Operating
ESC
Never press the ESC OFF but-
ton while ESC is operating (ESC
indicator light blinks).
If ESC is turned off while ESC is
operating, the vehicle may slip
out of control.
WARNING- Tire/ Wheel size
When replacing tires and wheels,
make sure they are the same size
as the original tires and wheels
installed. Driving with varying
tire or wheel sizes may diminish
any supplemental safety benefits
of the VSM system.

VSM operation
When the VSM is in operation, ESC
indicator light ( ) blinks.
When the vehicle stability manage-
ment is operating properly, you can
feel a slight pulsation in the vehicle
and/or abnormal steering responses
(EPS- Electronic Power Steering).
This is only the effect of brake and
EPS control and indicates nothing
unusual.
The VSM does not operate when:
Driving on a sloping road such as agradient 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 surface. A split-mu sur-
face is made of two surfaces which
have different friction forces.
WARNING
- Vehicle stability management
Drive carefully even though your
vehicle has Vehicle stability man-
agement. It can only assist you in
maintaining control under cer-
tain circumstances.

The Vehicle Stability Management
system is not a substitute for safe
driving practices but a supplemen-
tary function only. It is the respon-
sibility 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 fol-
low all the normal precautions for
driving at safe speeds for the condi-
tions – including driving in inclement
weather and on a slippery road.Hill-start assist control (HAC)
A vehicle has the tendency to roll
back on a steep hill when it starts to
go after stopping. The Hill-start
Assist Control (HAC) prevents the
vehicle from rolling back by applying
the brakes automatically for about 2
seconds. The brakes are released
when the accelerator pedal is
depressed or after about 2 seconds.
The HAC is activated only for about 2
seconds, so when the vehicle is
starting off always depress the accel-
erator pedal.
Good braking practices
Check to be sure the parking brakeis not engaged and the parking
brake indicator light is out before
driving away.
Driving through water may get the brakes wet. They can also get wet
when the vehicle is washed. Wet
brakes can be dangerous! Your
vehicle will not stop as quickly if the
brakes are wet. Wet brakes may
cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action
returns to normal, taking care to
keep the vehicle under control at all
times. If the braking action does not
return to normal, stop as soon as it
is safe to do so and call an author-
ized Kia dealer for assistance.
Don't coast down hills with the vehicle out of gear. This is extreme-
ly hazardous. Keep the vehicle in
gear at all times, use the brakes to
slow down, then shift to a lower
gear so that engine braking will
help you maintain a safe speed.
WARNING- Maintaining
Brake Pressure on Incline
HAC does not replace the need
to apply brakes while stopped on
an incline. While stopped, make
sure you maintain brake pres-
sure sufficient to prevent your
vehicle from rolling backward
and causing an accident. Don’t
release the brake pedal until you
are ready to accelerate forward.WARNING
For maximum protection, always
wear your seat belt. No system,
no matter how advanced, can
compensate for all driver error
and/or driving conditions.
Always drive responsibly.

Emergency braking (2nd warning)
The warning message appears onthe LCD display with the warning
alarms.
The FCA controls the brakes with- in certain limit to release shock
from the collision.
The FCA controls the maximum
brakes just before the collision.
- If you select "Warning only", theFCA system activates and pro-
duces only warning alarms in
accordance with the collision risk
levels. You should control the
brake directly because the FCA
system do not control the brake.
Brake operation
In an urgent situation, the braking system enters into the ready status
for prompt reaction against the dri-
ver’s depressing the brake pedal.
The FCA provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the brake or
accelerator pedal, or when the
driver abruptly operates the steer-
ing wheel.
The braking control is automatical- ly canceled, when risk factors dis-
appear.
OJF058390L
CAUTION
The driver should always paygreat caution to vehicle opera-tion, even though there is nowarning message or warningalarm.
WARNING
The FCA cannot avoid all colli-
sions. The FCA might not com-
pletely stop the vehicle before
collision, due to ambient,
weather and road conditions.
The driver has the responsibili-
ty to drive safely and control the
vehicle.
WARNING
The FCA operates in accor-
dance with the risk levels, such
as the distance from the vehicle
in front, the speed of the vehicle
in front, and the driver's vehicle
operation.
For the system to activate, do
not attempt risky driving.

(Continued)
• Use only genuine parts to repair orreplace a damaged
• Do not tint the window or install stickers, accessories around the
inside mirror where the camera is
installed.
• Make sure the frontal camera installation point does not get wet.
• Do not impact or arbitrarily remove any camera components.
• Do not place reflective objects(white paper or mirror etc.)
on the crash pad.
The system may activate unneces-
sarily due to reflect of the sunlight.
• Excessive audio volume may dis- turb the sound of the system warn-
ing alarm.
• For more cautions for the camera sensor, refer to the Lane Keeping
Assist system in this chapter.System malfunction
When the FCA is not working prop-
erly, the FCA warning light ( ) will
illuminate and the warning mes-
sage will appear for a few seconds.
After the message disappears, the
master warning light ( ) will illu-
minate. In this case, take your vehi-
cle to an authorized Kia dealer and
have the system inspected.
The FCA system will get deactivat- ed for the sake of driver's safety
when the ESC warning light comes
on. The FCA warning message will
appear at the same time, too. But
that doesn't necessarily mean the
malfunction of the FCA system. Both FCA warning light and warn-
ing message will disappear once
the ESC warning light issue is
resolved.
OJF058394L
WARNING
The FCA is only a supplemen-
tal system for the driver's con-
venience. The driver should
hold the responsibility to con-
trol the vehicle operation. Do
not solely depend on the FCA
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed.
In certain instances and under certain driving condi-
tions, the FCA system may
activate unintentionally. This
initial warning message
appears on the LCD display
with a warning chime.

Limitation of the system
The FCA is an assistant system for a
driver in a certain risky driving condi-
tion and it does not take every
responsibility for all risks from driving
condition.
The FCA monitors the driving situa-
tions through the camera sensor.
Thus, for a situation out of the sens-
ing range, the FCA may not normally
operate. The driver should pay great
caution in the following situations.
The FCA operation may be limited.
Recognizing vehicles
- The camera is contaminated withforeign substances.
- It heavily rains or snows.
- There is interruption by electric waves.
- The vehicle in front has a narrow body. (i.e. motor cycle and bicycle)
- The driver’s view is unclear due to the backlight, the reflected light, or
darkness.
- The camera cannot contain the full image of the vehicle in front.
- The vehicle in front is a special vehicle, such as a heavily-loaded
truck or a trailer.
- The outside brightness is greatly changed, such as entering/exiting
the tunnel.
- The vehicle driving is unstable.
- The camera sensor recognition is limited. - The driver's field of view is not well
illuminated (either too dark or too
much reflection or too much back-
light that obscures the field of view)
- The vehicle in front is driving errat- ically
- The vehicle is driven near areas containing metal substances such
as a construction zone, railroad,
etc.
- Backlight is reflected in the direc- tion of the vehicle (including front
light from the vehicle ahead)
- Moisture on the windshield is not completely removed or frozen.
- The weather is misty.
- The vehicle in front does not turn ON the rear lights, does not have
rear lights, has asymmetric rear
lights, or has rear lights out of
angle.
- The vehicle is on unpaved or uneven rough surfaces, or roads
with sudden gradient changes

Driving your vehicle
While driving on a curve, the FCA
may recognize the vehicle in front in
the next lane. Pay great caution, and,
if necessary, depress the brake pedal.
Or, depress the accelerator pedal to
maintain the driving speed. Always,
take a look around the vehicle for
your safety.- Driving on a slope
The FCA performance decreases
while driving upward or downward on
a slope, not recognizing the vehicle
in front in the same lane. It may
unnecessarily produce the warning
message and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
When the FCA suddenly recognizes
the vehicle in front while passing
over a slope, you may experience
sharp deceleration.
Always keep your eyes forward while
driving upward or downward on a
slope, and, if necessary, depress the
brake pedal.- Changing lanes
Even though the vehicle in the next
lane enters into your lane, it may not
be recognized by the FCA, until it
enters the FCA sensing range.
Especially when the vehicle in the
next lane abruptly enters into your
lane, it is more likely not be recog-
nized. Always pay great attention.
