Wet brakes may impair the vehicle’s
ability to safely slow down; the vehi-
cle may also pull to one side when
the brakes are applied. Applying the
brakes lightly will indicate whether
they have been affected in this way.
To dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.In the event of brake failure
If service brakes fail to operate while
the vehicle is in motion, you can
make an emergency stop with the
parking brake. The stopping dis-
tance, however, will be much greater
than normal.
Disc brakes wear indicator
When your brake pads are worn and
new pads are required, you will hear
a high-pitched warning sound from
your front brakes or rear brakes (if
equipped). You may hear this sound
come and go or it may occur when-
ever you depress the brake pedal.
Please remember that some driving
conditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
Always replace the front or rear
brake pads as pairs.
CAUTION - Replace brake
pads
Do not continue to drive withworn brake pads. Continuing todrive with worn brake pads candamage the braking system andresult in costly brake repairs.
WARNING - Parking brake
Avoid applying the parking
brake to stop the vehicle while it
is moving except in an emer-
gency situation. Applying the
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 parking brake to stop the
vehicle, use great caution in
applying the brake.

Releasing the parking brake
To release the parking brake,
depress the parking brake pedal a
second time while applying the foot
brake. The pedal will automatically
extend to the fully released position. Check the brake warning light by
turning the ignition switch ON (do not
start the engine). This light will illumi-
nate when the parking brake is
applied with the ignition switch in the
START or ON position.
Before driving, be sure the parking
brake is fully released and the brake
warning light is off.
If the brake warning light remains on
after the parking brake is released
while the hybrid system is in READY
state, there may be a malfunction in
the brake system. Immediate atten-
tion is necessary.

WARNING - Parking brake
use
All vehicles should always have
the parking brake fully engaged
when parking to avoid inadver-
tent movement of the vehicle
which can injure occupants or
pedestrians.

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
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.

then goes off if ESC system is oper-
ating normally.
The ESC indicator light blinks when-
ever ESC is operating.
The ESC indicator light blinks when-
ever ESC is operating or illuminates
when ESC fails to operate.
The ESC OFF indicator light comes
on when the ESC is turned off with
the button. Driving with varying tire or wheel
sizes may cause the ESC system to
malfunction. When replacing tires,
make sure they are the same size as
your original tires.
ESC OFF usage
When driving
It’s a good idea to keep the ESC
turned on for daily driving whenev-
er possible.
To turn ESC off while driving, press the ESC OFF button while driving
on a flat road surface.

WARNING - Operating ESC
Never press the ESC OFF but-
ton while ESC is operating.
If the ESC is turned off while
ESC is operating, the vehicle
may go out of control.
WARNING - Electronic
stability control
Drive carefully even though
your vehicle has Electronic
Stability Control. It can only
assist you in maintaining con-
trol under certain circum-
stances.

Driving your vehicle
Hill-start assist control (HAC)
Hill start Assist Control is a comfort
function. The main intent is to pre-
vent the vehicle from rolling back-
wards while driving uphill on an
inclined surface. HAC holds the brak-
ing pressure builtup by driver during
stopping procedure for 2 seconds
after releasing brake pedal.
During the pressure-hold period, the
driver has enough time to press the
accelerator pedal to drive off.
The braking pressure is reduced as
soon as the system detects the dri-
ver’s intention to drive off. The HAC does not operate when
the transaxle shift lever is in the P
(Park) or N (Neutral) position.
The HAC activates even though the ESC is off but it does not acti-
vate when the ESC has malfunc-
tioned.
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 detected changes in coeffi-
cient of friction between right wheels
and left wheels when braking.
VSM operation
When the vehicle stability manage-
ment is operating properly, you can
feel a slight pulsation in the vehicle.
This is only the effect of brake control
and indicates nothing unusual.
WARNING - Activating
HAC
Drivers should pay close atten-
tion when activating the HAC.
The vehicle may roll backward
causing an accident due to
insufficient brake hold pres-
sure.
