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
Your vehicle has disc brakes.
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. You
may hear this sound come and go or
it may occur whenever 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.
WARNING - Parking brake
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 cau-
tion in applying the brake.
CAUTION
Do not operate the parking brake while the vehicle is movingexcept in an emergency situa- tion. It could damage the vehiclesystem and make endanger driv-ing safety.
WARNING - Brake wear
This brake wear warning sound
means your vehicle needs serv-
ice. If you ignore this audible
warning, you will eventually lose
braking performance, whichcould lead to a serious accident.
CAUTION
To avoid costly brake repairs, do not continue to drive withworn brake pads.
Always replace the front or rear brake pads as pairs.

531
Driving your vehicle
Check the brake warning light by
turning the ignition switch ON (do not
start the engine). This light will be
illuminated 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 engine is running, there may be
a malfunction in the brake system.
Immediate attention is necessary.If at all possible, cease driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only contin-
ue to drive the vehicle until you can
reach a safe location or repair shop.

WARNING
To prevent unintentional movement when stopped and
leaving the vehicle, do not use
the gearshift lever in place of
the parking brake. Set theparking brake AND make sure
the gearshift lever is securely
positioned in P (Park) for auto-matic transmission equipped
vehicles.
Never allow anyone who is unfamiliar with the vehicle to
touch the parking brake. If theparking brake is released
unintentionally, serious injury
may occur.
All vehicles should always have the parking brake fully
engaged when parking to
avoid inadvertent movement
of the vehicle which can injureoccupants or pedestrians.

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.

CAUTION
If the ABS warning light is onand stays on, you may have aproblem with the ABS. In thiscase, however, your regularbrakes will work normally.
(Continued)
(Continued) The ABS warning light will stay on for approximately 3 sec-onds after the ignition switchis ON. During that time, theABS will go through self-diag-nosis and the light will go off ifeverything is normal. If thelight stays on, you may have aproblem with your ABS. Werecommend that you contactan authorized Kia dealer.CAUTION
When you drive on a road hav-
ing poor traction, such as anicy road, and operate your brakes continuously, the ABSwill be active continuously andthe 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.

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 malfunc-
tioning.
 Do not pump your brakes!
 Have the battery recharged before driving the vehicle.Electric parking brake (EPB) (if equipped)
