abnormally. Shut the engine off
and turn it on again after a few min-
utes. The warning light will go off
and the EPB switch will operate
normally. However, if the EPB
warning light is still on, have the
system checked by an authorized
Kia dealer.
If the parking brake warning light does not illuminate or blinks even
though the EPB switch was pulled
up, the EPB is not applied.
If the parking brake warning light blinks when the EPB warning light
is on, press the switch, then pull it
up. Once more press it back to its
original position and pull it back up.
If the EPB warning does not go off,
have the system checked by an
authorized Kia dealer.Emergency braking
If there is a problem with the brake
pedal while driving, emergency brak-
ing is possible by pulling up and
holding the EPB switch. Braking is
possible only while you are holding
the EPB switch.
✽ ✽ NOTICE
During emergency braking by the
EPB, the parking brake warning
light will illuminate to indicate that
the system is operating.
WARNING
Do not operate the electric park-
ing brake while the vehicle is
moving except in an emergency
situation. Applying the electric
parking brake while the vehicle
is moving at normal speeds can
cause a sudden loss of control
of the vehicle. If you must use
the electric parking brake to
stop the vehicle, use great cau-
tion in applying the brake.

message will appear to inform you
that EPB has been automatically
engaged. Before driving off again,
press foot brake pedal, check the
surrounding area near your vehi-
cle and release parking brake
manually with the EPB switch.
• If the AUTO HOLD indicator lights up yellow, the Auto Hold is
not working properly. Take your
vehicle to an authorized Kia deal-
er and have the system checked.
If there is a malfunction with the dri-
ver’s door, engine hood or trunk
open detection system, the Auto
Hold may not work properly.
Take your vehicle to an authorized
Kia dealer and have the system
checked.
✽ ✽ NOTICE
A click or electric brake motor
whine sound may be heard while
operating or releasing the EPB, but
these conditions are normal and
indicate that the EPB is functioning
properly.
WARNING
To reduce the risk of an acci-
dent, do not activate Auto Hold
while driving downhill, backing
up or parking your vehicle.

Anti-lock brake system (ABS)
ABS (or ESC) will not prevent acci-
dents 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 during
extreme road conditions.
The vehicle should be driven at
reduced speeds in the following cir-
cumstances:
When driving on rough, gravel or
snow-covered roads
When driving with tire chains installed
When driving on roads where the road surface is pitted or has differ-
ent surface heights.
Driving in these conditions increases
the stopping distance for your vehi-
cle. 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 cor-
responding sensation 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 emergency
situation, 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 allows the ABS to
control 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
system may result in a longer stop-
ping distance than for vehicles
equipped with a conventional
brake system.

531
Driving your vehicle
The ABS warning light will stay on for
approximately 3 seconds after the
ignition switch is ON. During that
time, the ABS will go through self-
diagnosis and the light will go off if
everything is normal. If the light stays
on, you may have a problem with
your ABS but your regular brakes will
work normally. Contact an authorized
Kia dealer as soon as possible. When you drive on a road with
poor traction, such as an icy road,
and operated your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light may illuminate. Pull your vehi-
cle over to a safe place and stop
the engine.
Restart the engine. If the ABS warning light is off, then your ABS
is normal. Otherwise, you may
have a problem with the ABS.
Contact an authorized Kia dealer
as soon as possible.
✽ ✽ 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 has mal-
functioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.

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 follow all the normal
precautions for driving - including
driving at safe speeds for the condi-
tions.
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.
