Anti-lock brake system (ABS)
WARNING
ABS (or ESC) will not prevent acci‐dents due to improper or dangerousdriving maneuvers. Even though ve‐hicle control is improved duringemergency braking, always maintaina safe distance between you and ob‐jects ahead. Vehicle speeds shouldalways be reduced during extremeroad conditions.The braking distance for vehicleequipped with an anti-lock brakingsystem (or Electronic Stability Con‐trol) may be longer than for thosewithout it in the following road con‐ditions.During these conditions the vehicleshould be driven at reduced speeds:•Rough, gravel or snow-coveredroads.
•With tire chains installed.
•On roads where the road surface ispitted or has different surfaceheight.
(Continued)
(Continued)
The safety features of an ABS (orESC) equipped vehicle should not betested by high speed driving or cor‐nering. This could endanger thesafety of yourself or others.
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 L

CAUTION
•If the ABS warning light is on andstays on, you may have a problemwith the ABS. In this case, howev‐er, your regular brakes will worknormally.
(Continued)
(Continued)
•The ABS warning light will stay onfor approximately 3 seconds afterthe engine start/stop buttonswitch is ON. During that time, theABS will go through self-diagnosisand the light will go off if every‐thing is normal. If the light stayson, you may have a problem withyour ABS. We recommend that youcontact an authorized Kia dealer.
CAUTION
•When you drive on a road havingpoor traction, such as an icy road,and operate your brakes continu‐ously, the ABS will be active con‐tinuously and the ABS warninglight may illuminate. Pull your ve‐hicle over to a safe place and stopthe engine.
•Restart the engine. If the ABSwarning light is off, then your ABSsystem is normal. Otherwise, youmay have a problem with the ABS.We recommend that you contactan authorized Kia dealer.
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 be‐
cause of the low battery voltage. It
does not mean your ABS is malfunc‐
tioning.
•Do not pump your brakes!
•Have the battery recharged before
driving the vehicle.

Electronic stability control (ESC)
(if equipped)
0+'
The electronic stability control (ESC)
system is designed to stabilize the ve‐ hicle during cornering maneuvers. ESC
checks where you are steering and
where the vehicle is actually going. ESC applies the brakes at individual wheels
and intervenes with engine manage‐
ment system to stabilize the vehicle.
WARNING
Never drive too fast for the roadconditions or too quickly when cor‐nering. Electronic stability control(ESC) will not prevent accidents. Ex‐cessive speed in turns, abrupt ma‐neuvers and hydroplaning on wetsurfaces can still result in serious ac‐cidents. Only a safe and attentivedriver can prevent accidents byavoiding maneuvers that cause thevehicle to lose traction. Even withESC installed, always follow all thenormal precautions for driving - in‐cluding driving at safe speed for theconditions.
The electronic stability control (ESC)
system is an electronic system de‐ signed to help the driver maintain vehi‐
cle control under adverse conditions. It
is not a substitute for safe driving 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 speed and to leave a suf‐ ficient margin of safety. When you apply your brakes under
conditions which may lock the wheels,
you may hear a L

ESC operation
ESC ON condition
-• When the engine start/stopbutton is turned ON, ESC
and ESC OFF indicator lights
illuminate for approximate‐
ly 3 seconds, then ESC is turned on.
• Press the ESC OFF button for at least half a second
after turning the ignition
ON to turn ESC off. (ESC
OFF indicator will illumi‐
nate). To turn the ESC on, press the ESC OFF button
(ESC OFF indicator light will
go off).
• When starting the engine, you may hear a slight tick‐
ing sound. This is the ESC
performing an automatic
system self-check and does not indicate a problem.
When operating
When the ESC is in operation, ESC indicator light blinks. • When the Electronic Stabili‐ ty Control is operating
properly, you can feel a
slight pulsation in the vehi‐
cle. This is only the effect of brake control and indi‐
cates nothing unusual.
• When moving out of the mud or slippery road, the
engine rpm (revolution per
minute) may not increase
even if you press the accel‐ erator pedal deeply. This is
to maintain the stability
and traction of the vehicle
and does not indicate a
problem.
ESC operation off
ESC OFF state
This car has 2 kinds of ESC off states.If the engine stops when ESC
is off, ESC remains off. Upon
restarting the engine, the ESCwill automatically turn on
again.

The ESC indicator light blinks whenever
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.
CAUTION
Driving with varying tire or wheelsizes may cause the ESC system tomalfunction. When replacing tires,make sure they are the same size asyour original tires.
WARNING
The Electronic Stability Control sys‐tem is only a driving aid; use precau‐tions for safe driving by slowingdown on curved, snowy, or icy roads.Drive slowly and don’t attempt toaccelerate whenever the ESC indica‐tor light is blinking, or when the roadsurface is slippery.
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 aflat road surface.
WARNING
Never press the ESC OFF buttonwhile ESC is operating (ESC indicatorlight blinks).If ESC is turned off while ESC is op‐erating, the vehicle may slip out ofcontrol.
NOTICE
•When operating the vehicle on a
dynamometer, ensure that the
ESC is turned off by pressing the
ESC OFF button for more than 3
seconds (ESC OFF light illumina‐
ted). If the ESC is left on, it may
prevent the vehicle speed from in‐
creasing, and result in false diag‐
nosis.
•Turning the ESC off does not af‐
fect ABS or brake system opera‐
tion.
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 be‐
tween right wheels and left wheels
when braking.
VSM operation
When the VSM is in operation, • ESC (Electronic Stability Control) ()
light will blink.
• The steering wheel may be control‐ led.
When the vehicle stability management is operating properly, you can feel a
slight pulsation in the vehicle. This is
only the effect of brake control and in‐ dicates nothing unusual.
The VSM does not operate when:
• Driving on bank road such as gradient or incline
• Driving rearward
• ESC OFF indicator light (
