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 orsnow-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 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
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.

Driving your 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.
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.

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 inclement
weather and on a slippery road.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
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.

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 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.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.

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.

Prerequisite for activation
The FCA will activate when the FCA
is selected on the LCD display, and
when the following prerequisites are
satisfied:
- The ESC (Electronic StabilityControl) is activated.
- The driving speed is over 6 mph (10 km/h). (The FCA only works
within a certain range of vehicle
speeds)
- When the FCA recognizes a vehi- cle or the pedestrian in front. (The
FCA may not recognize every
obstacle or provide warnings and
braking in every situation, so do
not rely on the FCA to stop the
vehicle in instances where the driv-
er sees an obstacle and has the
ability to apply the brakes)
FCA warning message and
system control
The FCA system produces warning
messages, warning alarms, and
emergency braking based on the level
of risk of a frontal collision, such as
when a vehicle ahead suddenly
brakes, or when the system detects
that a collision with a pedestrian is
imminent.
The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward
Collision Warning include Early,
Normal or Late initial warning time.
WARNING
The FCA automatically acti-vates upon placing the igni-
tion switch to the ON position.
The driver can deactivate the
FCA by canceling the system
setting on the LCD display.
The FCA automatically deacti- vates upon canceling the
ESC. When the ESC is can-
celed, the FCA cannot be acti-
vated on the LCD display.
The FCA warning light will
illuminate.
Set or cancel FCA after stop- ping the vehicle in the safe
place for your safety.

Collision Warning (1st warning)
The warning message appears on
the LCD display with the warning
alarms.
The FCA system limitedly controls the brakes to preemptively mitigate
impact in a collision.
Emergency braking (2nd warning)
The warning message appears onthe LCD display with the warning
alarms.
The FCA system limitedly controls the brakes to preemptively mitigate
impact in a collision.
The brake control is maximized
just before a collision.
Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction to assist the
driver in depressing the brake
pedal.
The FCA system provides addi- tional braking power for potentially
improved braking performance
when the driver depresses the
brake pedal.
The braking control is automatical- ly deactivated when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The braking control is automatical- ly canceled when risk factors dis-
appear.
The driver should always pay great
caution to vehicle operation, even
though there is no warning message
or warning alarm.

The cruise control system allows you
to program the vehicle to maintain a
constant speed without depressing
the accelerator pedal.
This system is designed to function
above approximately 20 mph (30
km/h).
If the cruise control is left on,
(CRUISE indicator light in the instru-
ment cluster illuminated) the cruise
control can be switched on acciden-
tally. Keep the cruise control system
off (CRUISE indicator light OFF)
when the cruise control is not in use,
to avoid inadvertently setting a speed. Use the cruise control system only
when traveling on open highways in
good weather.
Do not use the cruise control when
driving in heavy or varying traffic, or
on slippery (rainy, icy or snow-cov-
ered) or winding roads or over 6%
up-hill or down-hill roads.
✽ ✽
NOTICE
• During normal cruise control oper-
ation, when the SET switch is acti-
vated or reactivated after applying
the brakes, the cruise control will
activate after approximately 3 sec-
onds. This delay is normal.
• To activate cruise control, depress the brake pedal at least once after
turning the engine start/stop but-
ton to the ON position or starting
the engine. This is to check if the
brake switch, which is an impor-
tant part to cancelling cruise con-
trol, is in normal condition.
CRUISE CONTROL SYSTEM
WARNING - Misuse of
Cruise Control
Do not use cruise control if the
traffic situation does not allow
you to drive safely at a constant
speed and with sufficient dis-
tance to the vehicle in front.

or "SET-" lever was used to cancel
cruising speed and the system is still
activated, the cruising speed will
automatically resume when you
push the lever up (RES+) or down
(SET-).
If you push the lever up (RES+), the
speed will resume to the recently set
speed. However, if vehicle speed
drops below 20 mph (30 km/h), it will
resume when there is a vehicle in
front of your vehicle.
✽ ✽ NOTICE
To reduce the risk of an accident,
