EPB malfunction indicator (if equipped)
This warning light illuminates if the
engine start/stop button is changed
to the ON position and goes off in
approximately 3 seconds if the sys-
tem is operationg normally.
If the EPB malfunction indicator
remains on, comes on while driving,
or does not come on when the igni-
tion switch or the engine start/stop
button is changed to the ON position,
this indicates that the EPB may have
malfunctioned. If this occurs, have your vehicle
checked by an authorized Kia dealer
as soon as possible.
The EPB malfunction indicator may
illuminate when the ESC indicator
comes on to indicate that the ESC is
not working properly, but it does not
indicate a malfunction of the EPB.
The EPB warning light may illumi-
nate if the EPB switch operates
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.
If you notice a continuous noise or
burning smell when the EPB is used
for emergency braking, have your
vehicle checked by an authorized Kia
dealer.
When the EPB (electronic parking
brake) is not released
If the EPB does not release normal-
ly, take your vehicle to an authorized
Kia dealer by loading the vehicle on
a flatbed tow truck and have the sys-
tem checked.
WARNING
Do not operate the electronic
parking brake while the vehicle is
moving except in an emergency
situation. Applying the electronic
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
electronic parking brake to stop
the vehicle, use great caution in
applying the brake.

seat belt must be fastened. 2.When coming to a complete stop
by depressing the brake pedal, the
AUTO HOLD indicator changes
from white to green indicating the
AUTO HOLD is engaged and EPB
is applied. The vehicle will remain
at a standstill even if you release
the brake pedal.
3.If EPB is applied, Auto Hold will be released.

tion system, the Auto Hold may not
work properly.

Driving 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 circumstances:
When driving on rough, gravel orsnow-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 vehicle. 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 benefit
from your ABS in an emergency situa-
tion, do not attempt to modulate your
brake pressure and do not try to pump
your brakes. Press your brake pedal as
hard as possible to allow 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.

The ABS warning light will stay on for
approximately 3 seconds after the
engine start/stop button 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. Contact an
authorized Kia dealer as soon as
possible. When you drive on a road having
poor traction, such as an icy road,
and have operated your brakes
continuously, the ABS will be active
continuously 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 goes off, then your
ABS system 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 low battery voltage. It does not
mean your ABS has malfunctioned.
• 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.

Driving your 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 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.
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.
