Anti-lock brake system (ABS)
The ABS continuously senses the
speed of the wheels. If the wheels
are going to lock, the ABS system
repeatedly modulates the hydraulic
brake pressure to the wheels.
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 ABS is active.
In order to obtain the maximum ben-
efit from your ABS in an emergencysituation, do not attempt to modulate
your brake pressure and do not try to
pump your brakes.Press your brake pedal as hard as
possible or as hard as the situation
warrants and allow the ABS to con-
trol the force being delivered to the
brakes.
✽✽
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 anti-lock brake
system is functioning properly.
Even with the anti-lock brake sys- tem, your vehicle still requires suf-
ficient stopping distance. Always
maintain a safe distance from the
vehicle in front of you.
Always slow down when cornering. The anti-lock brake system cannot
prevent accidents resulting from
excessive speeds.
On loose or uneven road surfaces, operation of the anti-lock brake sys-
tem may result in a longer stopping
distance than for vehicles equipped
with a conventional brake system.
(Continued)
On roads where the road sur-face is pitted or has different surface height.
The safety features of an ABS
(or ESC) equipped vehicle
should not be tested by high
speed driving or cornering. This
could endanger the safety of
yourself or others.
WARNING
ABS (or ESC) will not prevent
accidents due to improper or
dangerous driving maneuvers.
Even though vehicle control is
improved during emergency
braking, always maintain a safe
distance between you and
objects ahead. Vehicle speeds
should always be reduced dur-
ing extreme road conditions.
The braking distance for cars
equipped with an anti-lock brak-
ing system (or Electronic
Stability Control system) may be
longer than for those without it
in the following road conditions. During these conditions the
vehicle should be driven atreduced speeds:
Rough, gravel or snow-cov- ered roads.
With tire chains installed.

✽✽NOTICE
When you jump start your vehicle
because of a drained battery, the
engine may not run as smoothly and
the ABS warning light may turn on at
the same time. This happens because
of the low battery voltage. It does not
mean your ABS is malfunctioning.
 Do not pump your brakes!
 Have the battery recharged before driving the vehicle.
W-78
CAUTION
If the ABS warning light is on
and stays on, you may have aproblem with the ABS. In thiscase, however, your regularbrakes will work normally.
The ABS warning light will stay on for approximately 3 secondsafter the Engine Start/Stop but-ton is ON. During that time, theABS will go through self-diag- nosis and the light will go off ifeverything is normal. If the lightstays on, you may have a prob- lem with your ABS. We recom-mend that you contact anauthorized Kia dealer.
CAUTION
When you drive on a road hav- ing poor traction, such as anicy road, and operate yourbrakes continuously, the ABSwill be active continuously and the ABS warning light may illu-minate. Pull your car over to asafe place and stop the engine.
Restart the engine. If the ABS warning light is off, then yourABS system is normal.Otherwise, you may have aproblem with the ABS. We rec-ommend that you contact an authorized Kia dealer.

Electronic Stability Control (ESC) (If equipped) 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. The Electronic Stability Control (ESC) system is an electronic sys-
tem designed to help the driver main-
tain vehicle control under adverse
conditions. It is not a substitute for
safe driving practices. Factors includ-
ing speed, road conditions and driv-
er steering input can all affect
whether ESC will be effective in pre-
venting 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 cor-
responding sensation in the brake
pedal. This is normal and it means
your ESC is active.
OKH052043
WARNING
Never drive too fast according to
the road conditions or too quick-
ly when cornering. Electronic
Stability Control (ESC) will not
prevent accidents. Excessive
speed in turns, abrupt maneu-
vers and hydroplaning on wetsurfaces can still result in seri-
ous accidents. Only a safe and
attentive driver can prevent acci-
dents by avoiding maneuvers
that cause the vehicle to lose
traction. Even with ESC
installed, always follow all the
normal precautions for driving -
including driving at safe speeds
for the conditions.

Indicator light
When Engine Start/Stop button is
pressed is turned to the ON position,
the indicator light illuminates, then
goes off if the ESC system is operat-
ing normally.
The ESC indicator light blinks when-
ever ESC is operating or illuminates
when ESC fails to operate. ESC OFF indicator light comes on
when the ESC is turned off with the
button.
ESC OFF usage
When driving
ESC should be turned on for dailydriving 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 operation.

CAUTION
Driving with varying tire or wheel
sizes may cause the ESC systemto malfunction. When replacing tires, make sure they are thesame size as your original tires.
WARNING
The Electronic Stability Control
is only a driving aid; use pre-
cautions for safe driving by
slowing down on curved,
snowy, or icy roads. Drive slow-
ly and don’t attempt to acceler-
ate whenever the ESC indicator
light is blinking, or when the
road surface is slippery.WARNING
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.
