If you do not apply the brake pedal
when you release the Auto Hold by
pressing the [AUTO HOLD] switch, a
warning will sound and a message
will appear.When you press the [AUTO HOLD]
switch, if the driver's door and engine
hood are not closed or the driver's

Anti-lock brake system (ABS)
ABS (or ESC) will not prevent acci-
dents due to improper or dangerous
driving maneuvers. Even though
ABS (or ESC) helps improve vehicle
control during emergency braking,
always maintain a safe distance
between you and objects ahead.
Vehicle speeds should always be
reduced during extreme road condi-
tions. 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 vehicle.
ORJ058158LORJ058159L

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 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
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
K900 Kia dealer as soon as possible.

Driving your vehicle
When you drive on a road havingpoor 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 K900
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) system
Electronic Stability Control (ESC)
system is designed to stabilize 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 management system
to stabilize the vehicle. Electronic Stability Control (ESC)
system 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 conditions.
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.

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 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.

✽ ✽NOTICE
• When operating the vehicle on a
dynamometer, ensure that the
ESC is turned off (ESC OFF light
illuminated). If the ESC is left on,
it may prevent the vehicle speed
from increasing, and result in false
diagnosis.
• Turning the ESC off does not affect ABS or brake system operation.
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 detects changes in coeffi-
cient of friction between the right
wheels and left wheels when brak-
ing.
VSM operation
When the VSM is in operation, the
ESC indicator light ( ) blinks.
When the vehicle stability manage-
ment is operating properly, you can
feel a slight pulsation in the vehicle
and/or abnormal steering responses
(EPS- Electronic Power Steering).
This is only the effect of brake and
EPS control and indicates nothing
unusual.
The VSM does not operate when:
Driving on a sloping road such as a
gradient or incline
Driving in reverse
ESC OFF indicator light ( ) remains on the instrument cluster
EPS indicator light remains on the instrument cluster
WARNING- Tire/
Wheel size
When replacing tires and wheels,
make sure they are the same size
as the original tires and wheels
installed. Driving with varying
tire or wheel sizes may diminish
any supplemental safety benefits
of the VSM system.

Driving your vehicle
Hill-start Assist Control (HAC)
A vehicle has the tendency to roll
back on a steep hill when it starts to
go after stopping. The Hill-start
Assist Control (HAC) prevents the
vehicle from rolling back by applying
the brakes automatically for about 2
seconds. The brakes are released
when the accelerator pedal is
depressed or after about 2 seconds.
The HAC is activated only for about 2
seconds, so when the vehicle begins
to roll, always depress the accelera-
tor pedal.
Good braking practices
Check to be sure the parking brakeis not engaged and the parking
brake indicator light is out before
driving away.
Driving through water may get the brakes wet. They can also get wet
when the vehicle is washed. Wet
brakes can be dangerous! Your
vehicle will not stop as quickly if the
brakes are wet. Wet brakes may
cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action
returns to normal, taking care to
keep the vehicle under control at all
times. If the braking action does not
return to normal, stop as soon as it
is safe to do so and call an author-
ized K900 Kia dealer for assis-
tance.
Don't coast down hills with the vehicle out of gear. This is extreme-
ly hazardous. Keep the vehicle in
gear at all times, use the brakes to
slow down, then shift to a lower
gear so that engine braking will
help you maintain a safe speed.WARNING- Maintaining
Brake Pressure on Incline
HAC does not replace the need
to apply brakes while stopped on
an incline. While stopped, make
sure you maintain brake pres-
sure sufficient to prevent your
vehicle from rolling backward
and causing an accident. Don’t
release the brake pedal until you
are ready to accelerate forward.
