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.

ESC operation off
ESC OFF stateThis car has 2 kinds of ESC
off states.
If the engine stops when
ESC is off, ESC remains off.
Upon restarting the engine,
the ESC will automatically
turn on again.
ESC off state 1
To cancel ESC operation, press the
ESC OFF button (ESC OFF )
shortly (ESC OFF indicator light
(ESC OFF ) illuminates). At this
state, the engine control function
does not operate. It means the trac-
tion control function does not oper-
ate. Brake control function only oper-
ates.
To cancel ESC operation, press the
ESC OFF button (ESC OFF ) for
more than 3 seconds. ESC OFF indi-
cator light (ESC OFF ) illuminates
and ESC OFF warning chime will
sound. At this state, the engine con-
trol function and brake control func-
tion do not operate. It means the car
stability control function does not
operate any more.

✽ ✽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 opera-
tion.
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). This is only the effect of brake
and EPS control and indicates noth-
ing unusual.
The VSM does not operate when:
Driving on bank road such as gra-
dient 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 is
starting off always depress the accel-
erator 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
authorized Kia dealer for assis-
tance.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
pressure sufficient to prevent
your vehicle from rolling back-
ward and causing an accident.
Don’t release the brake pedal
until you are ready to accelerate
forward.

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 transmission, 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 transmission). If your vehicle
is facing downhill, turn the front
wheels into the curb to help keep
the vehicle from rolling. If your vehi-
cle 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
transmission) and block the rear
wheels so the vehicle cannot roll.
Then release the parking brake.
Do not hold the vehicle on the upgrade with the accelerator
pedal. This can cause the trans-
mission 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 on.
- The driving speed is over 10 km/h (6 mph). (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) The FCA automatically activates
upon placing the ignition switch to
the ON position. The driver can
deactivate the FCA by canceling the
system setting on the LCD display.
The FCA automatically deactivates upon canceling the ESC. When the
ESC is cancelled, the FCA cannot
be activated on the LCD display.
The FCA warning light will illumi-
nate, but it does not indicate a mal-
function of the system.
Set or cancel FCA with controlling switches on steering wheel after
stopping the vehicle in the safe
place for your safety.
FCA warning message and
system control
The FCA produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels of
followings like vehicle’s sudden brak-
ing in front or lack of vehicle to vehicle
distance or collision to pedestrians.
Also, it controls the brakes in accor-
dance with the collision risk levels.
WARNING
To avoid driver distractions, do
not attempt to set or cancel the
FCA while operating the vehicle.

Collision Warning (1st warning)
• The warning message appears on
the LCD display with the warning
alarms.
The FCA controls the brakes within certain limit to release shock from
the collision.
Emergency braking (2nd warning)
The warning message appears onthe LCD display with the warning
alarms.
The FCA controls the brakes with- in certain limit to release shock
from the collision.
The FCA controls the maximum
brakes just before the collision.
Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction against the dri-
ver’s depressing the brake pedal.
The FCA 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 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 exercise
caution when operating the vehicle,
even though there is no warning
message or warning alarm.

System malfunction
When the FCA is not working prop-erly, the FCA warning light ( )
will illuminate and the warning
message will appear for a few sec-
onds. After the message disap-
pears, the master warning light
( ) will illuminate. In this case,
have the vehicle inspected by an
authorized Kia dealer.
The FCA warning message may appear along with the illumination
of the ESC warning light. The FCA may unnecessarily pro-
duce warning messages and warn-
ing alarms. Due to the sensing lim-
itation, the FCA may not produce
warning messages or warning
alarm at all.
When there is a malfunction with the FCA, the braking control does
not operate upon detecting a colli-
sion risk even with other braking
systems normally operating.
The FCA operates only for the vehicle / pedestrian in front, while
driving forward. It does not operate
for any animals or vehicles in the
opposite direction.
The FCA can not recognize cross- traffic or parked vehicles present-
ing a sideprofile.
OUM058284L
WARNING
The FCA is only a supplemental
system for the driver’s conven-
ience.
The driver still maintains
responsibility to control the
vehicle. Do not solely depend
on the FCA system. Rather,
maintain a safe braking dis-
tance, and, if necessary,
depress the brake pedal to
lower the driving speed.

If the vehicle in front stops sudden-
ly, you may have less control of the
brake system.
Therefore, always keep safe dis-
tance between your vehicle and
the vehicle in front of you.
The FCA system may activate dur- ing braking and the vehicle may
stop suddenly. And the load in the
vehicle may endanger passengers.
Therefore, always be mindful of the
load volume in the vehicle.
The FCA system may not activate if the driver applies the brake pedal
to avoid risk of collision.
The FCA system does not operate when the vehicle is in reverse. In
these cases, you must maintain a
safe braking distance, and if nec-
essary, depress the brake pedal to
reduce the driving speed in order
to maintain a safe distance. The regular braking function will
operate normally even if There is a
problem with the FCA brake control
system or other functions. In this
case, the braking control will not
operate in the risk of a collision.
The FCA system may not activate according to driving condition, traf-
fic on the road, weather, road con-
dition, etc.
The FCA system may not activate to all types of vehicles.Limitation of the system
The FCA is an assistant system for a
driver in a certain risky driving condi-
tion and it does not take every
responsibility for all risks from driving
condition.
The FCA monitors the driving situa-
tions through the radar and the cam-
era sensor. Thus, for a situation out
of the sensing range, the FCA may
not operate normally. The driver
should use caution in the following
situations. The FCA operation may
be limited.

- When the back light is projected in
the direction of the vehicle's motion
(including the headlights of vehi-
cles)
- Road sign, shadow on the road, tunnel entrance, toll gate, partial
pavement
- Driving on a curve
The FCA performance decreases
while driving on a curve. The FCA
may not recognize the vehicle in front
even in the same lane. It may unnec-
essarily produce the warning mes-
sage and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
While driving on a curve, exercise
caution, and, if necessary, depress
the brake pedal. The FCA system may recognize a
vehicle in the next lane when driving
on a curved road.
In this case, the system may unnec-
essarily alarm the driver and apply
the brake.
Always pay attention to road and
driving conditions, while driving. If
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
