AUTO HOLD conditions not met.
Close door, hood, and fasten seatbelt

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
will sound and a message will
appear on the LCD display. At this
moment, press the [AUTO HOLD]
button after closing the driver’s door,
engine hood and fastening the seat
belt.

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.

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
engine start/stop button 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.

6 39

Driving your vehicle

Malfunction indicator

The VSM can be deactivated even if
you don’t cancel the VSM operation
by pressing the ESC OFF button. It
indicates that a malfunction has
been detected somewhere in the
Electric Power Steering system or
VSM system. If the ESC indicator
light (

) or EPS warning light

remains on, take your vehicle to an
authorized Kia dealer and have the
system checked.

✽

✽

NOTICE

• The VSM is designed to function

above approximately 13 mph (22
km/h) on curves.

• The VSM is designed to function

above approximately 6 mph (10
km/h) when a vehicle is braking on
a split-mu surface. A split-mu sur-
face is made of two surfaces which
have different friction forces.

• The Vehicle Stability Management

system is not a substitute for safe
driving practices but a supplemen-
tary function only. It is the respon-
sibility of the driver to always check
the speed and the distance to the
vehicle ahead. Always hold the
steering wheel firmly while driving.

• Your vehicle is designed to activate

according to the driver’s intention,
even with installed VSM. Always fol-
low all the normal precautions for
driving at safe speeds for the condi-
tions – including driving in clement
weather and on a slippery road.

✽

✽

NOTICE

For maximum protection, always
wear your seat belt. No system, no
matter how advanced, can compen-
sate for all driver error and/or driv-
ing conditions. Always drive respon-
sibly.

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 is
starting off always depress the accel-
erator pedal.

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.

Good braking practices

• Check to be sure the parking brake

is 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 Kia dealer for assistance.

• 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.

• Don't "ride" the brake pedal.

Resting your foot on the brake
pedal while driving can be danger-
ous because the brakes might
overheat and lose their effective-
ness. It also increases the wear of
the brake components.

• If a tire goes flat while you are driv-

ing, apply the brakes gently and
keep the vehicle pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe place.

• If your vehicle is equipped with an

Automatic Transaxle, don't let your
vehicle creep forward. To avoid
creeping forward, keep your foot
firmly on the brake pedal when the
vehicle is stopped.

• Be cautious when parking on a hill.

Firmly engage the parking brake
and place the shift lever in P (auto-
matic transaxle). If your vehicle is
facing downhill, turn the front
wheels into the curb to help keep
the vehicle from rolling.

If your vehicle is facing uphill, turn
the front wheels away from the
curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to
keep the vehicle from rolling, block
the wheels.

• Under some conditions your park-

ing brake can freeze in the
engaged position. This is most like-
ly to happen when there is an
accumulation of snow or ice
around or near the rear brakes or if
the brakes are wet. If there is a risk
that the parking brake may freeze,
apply it only temporarily while you
put the shift lever in P (automatic
transaxle) and block the rear
wheels so the vehicle cannot roll.
Then release the parking brake.

• Do not hold the vehicle on an

incline with the accelerator pedal.
This can cause the transaxle to
overheat. Always use the brake
pedal or parking brake.

Driving your vehicle

The AEB system is to reduce or to
avoid accident risk. It recognizes the
distance from the vehicle ahead or
the pedestrian through the sensors
(i.e. radar and camera), and, if nec-
essary, warns the driver of accident
risk with the warning message or the
warning alarms.

✽

✽

NOTICE

Take the following precautions when
using the Autonomous Emergency
Braking (AEB):
• This system is only a supplemental

system and it is not intended to,
nor does it replace the need for
extreme care and attention of the
driver. The sensing range and
objects detectable by the sensors
are limited. Pay attention to the
road conditions at all times.

• NEVER drive too fast in accor-

dance with the road conditions or
while cornering.

• Always drive cautiously to prevent

unexpected and sudden situations
from occurring. AEB does not stop
the vehicle completely and does
not avoid collisions.

System setting and activation

System setting

The driver can activate the AEB by
placing the engine start/stop button
to the ON position and by selecting
'User Settings', 'Driving Assist', and
'Autonomous Braking System'. The
AEB deactivates, when the driver
cancels the system setting.

Driving your vehicle

•

EARLY

-

When this condition is
selected, the initial
Forward Collision Warning
is activated earlier than
normal. This setting maxi-
mizes the amount of dis-
tance between the vehicle
or pedestrian ahead before
the initial warning occurs.

• NORMAL - When this condition is

selected, the initial
Forward Collision
Warning is activated nor-
mally. This setting allows
for a nominal amount of
distance between the
vehicle or pedestrian
ahead before the initial
warning occurs.

•

LATE

-

When this condition is

selected, the initial Forward
Collision Warning is activat-
ed later than normal. This
setting reduces the amount
of distance between the
vehicle or pedestrian ahead
before the initial warning
occurs.

Prerequisite for activation

The AEB will activate activated when
the AEB is selected on the LCD dis-
play, and when the following prereq-
uisites are satisfied:
- The ESC (Electronic Stability

Control) is activated.

- The driving speed is over 6 mph.

(The AEB only works within a cer-
tain range of vehicle speeds)

- When the AEB recognizes a vehi-

cle or the pedestrian in front. (The
AEB may not recognize every
obstacle or provide warnings and
braking in every situation, so do
not rely on the AEB to stop the
vehicle in instances where the driv-
er sees an obstacle and has the
ability to apply the brakes)

• The AEB automatically activates

when you turn the vehicle on.
The driver can deactivate the AEB
by canceling the in the system set-
ting on the LCD display.

• The AEB automatically deactivates

when canceling the ESC. When the
ESC is canceled, the AEB cannot

AEB warning message and
system control

The AEB produces warning mes-
sages, warning alarms, and emer-
gency braking based on the level of
risk of a frontal collision, such as
when a vehicle ahead suddenly
brakes, when there is no following dis-
tance from the vehicle in front, or
when it detects a collision with a
pedestrian is imminent.

Forward Warning (1st warning)

The warning message appears on
the LCD display with the warning
alarms.

Collision Warning (2nd warning)

• The warning message appears on

the LCD display with the warning
alarms.

• The AEB applies the brakes within

certain limit to reduce the impact
from a collision.

warning)

• The warning message appears on

the LCD display with the warning
alarms.

• The AEB controls the brakes with-

in certain limit to release shock
from the collision.
The AEB controls the maximum
brakes just before the collision.

Brake operation

• In an urgent situation, the braking

system enters into the ready status
for prompt reaction against the dri-
ver’s depressing the brake pedal.

• The AEB provides additional brak-

ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.

• The braking control is automatical-

ly deactivated, when the driver
sharply depresses the brake pedal,
or when the driver abruptly turns
the steering wheel.

• The braking control is automatical-

ly canceled, when risk factors dis-
appear.

The driver should always exercise
caution when operating the vehicle,
even though there is no warning
message or warning alarm.

✽

✽

NOTICE

The AEB operates in accordance
with the risk levels, such as the dis-
tance from the vehicle/passer-by in
front, the speed of the vehicle/pass-
er-by in front, and the driver's vehi-
cle operation.

OJF055078L

WARNING

The AEB cannot avoid all colli-
sions. The AEB might not com-
pletely stop the vehicle before
collision, due to ambient weath-
er and road conditions. The
driver has the responsibility to
drive safely and control the
vehicle.

Sensor to detect the distance
from the vehicle in front
(front radar)

The sensor is to maintain a certain
distance from the vehicle in front.
However, the smudged sensor lens
with foreign substances, such as
snow and rain, adversely affects the
sensing performance. It may even
temporarily cancel the AEB. Always
keep the sensor lens clean.

Warning message and warning
light

When the sensor is covered or the
sensor lens is dirty with foreign sub-
stances, such as snow or rain, the
AEB operation may temporarily stop.
In this case, a warning message will
appear to notify the driver.

This is not a malfunction with the
AEB. To operate the AEB again,
remove the foreign substances.

✽

✽

NOTICE

• Do not install any accessories, such

as a license plate bracket or
bumper sticker near the sensor
area. Do not replace the bumper
by yourself. Doing so may adverse-
ly affect the sensing performance.

• Always keep the sensor/bumper

area clean.

• Use only a soft cloth to wash the

vehicle. Also, do not spray highly
pressurized water on the sensor
installed on the bumper.

• Be careful not to apply unneces-

sary force on the frontal sensor
area. When the sensor moves out
of the correct position due to
external force, the system may not
operate correctly even without the
warning light or message. In this
case, have your vehicle inspected
by an authorized Kia dealer.

• Use only the genuine Kia sensor

cover. Do not arbitrarily apply
paint on the sensor cover.
