Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
In the event that the power-assisted
brakes lose power because of a
stalled engine or some other reason,
you can still stop your vehicle by
applying greater force to the brake
pedal than you normally would. The
stopping distance, however, will be
longer.
When the engine is not running, the
reserve brake power is partially
depleted each time the brake pedal
is applied. Do not pump the brake
pedal when the power assist has
been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces. 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.
Always test your brakes in this fash-
ion after driving through deep water.
To dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
BRAKE SYSTEM
WARNING- Steep hill
braking
Avoid continuous application of
the brakes when descending a
long or steep hill by shifting to a
lower gear. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
CAUTION- Brake Pedal
Do not drive with your foot rest- ing on the brake pedal. This willcreate abnormally high braketemperatures which can causeexcessive brake lining and padwear.

Driving your vehicle
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. 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.
Always replace the front or rear
brake pads as pairs.
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.
WARNING- Brake wear
Do not ignore high pitched wear
sounds from your brakes. If you
ignore this audible warning, you
will eventually lose braking per-
formance, which could lead to a
serious accident.
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.

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 operating 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.

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

Driving your vehicle
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. 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.
