When you press the [AUTO HOLD]
switch, if the driver’s door, engine
hood are not closed or the driver’s
seat belt is unfastened, a warning

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 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.

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 or as hard as the sit-
uation allows 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.

OJF055124L

6 43

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.

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 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.

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 right wheels
and left wheels when braking.

VSM operation

When the VSM is in operation, 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

VSM operation off

If you press the ESC OFF button to
turn off the ESC, the VSM will also
cancel and the ESC OFF indicator
light (

) illuminates.

To turn on the VSM, press the button
again. The ESC OFF indicator light
goes out.

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.
