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 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 mal-
functioned.
• 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.

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
Electronic stability control
(ESC) will not prevent acci-
dents. Excessive speed in
turns, abrupt maneuvers and
hydroplaning on wet surfaces
can still result in serious acci-
dents. 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 precau-
tions for driving - including driv-
ing at safe speeds for the condi-
tions.

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) (if equipped)
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.

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 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
authorized 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.
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.
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.

543
Driving your vehicle
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 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
transmission) 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 transmission to
overheat. Always use the brake
pedal or parking brake.

Driving your vehicle
The warning light illumi-
nates on the LCD display,
when you cancel the FCA
system. The driver can
monitor the FCA ON/OFF status on
the LCD display. Also, the warning
light illuminates when the
ESC(Electronic Stability Control) is
turned off (Traction & Stability control
disabled.). When the warning light
remains ON with the FCA activated,
have the system checked by an
authorized Kia dealer.
The driver can select the initial warn-
ing activation time in the User
Settings in the instrument cluster
LCD display. The options for the ini-
tial Forward Collision Warning
include the following:
selected, the initial
Forward Collision Warning
is activated earlier than
normal. If the ‘EARLY’ con-
dition feels too sensitive,
change it into ‘NORMAL’.
selected, the initial
Forward Collision
Warning is activated nor-
mally.
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. Select this condition
only when traffic is light,
and you are driving slowly.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 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.
WARNING
The FCA may not recognize
every obstacle or provide warn-
ings and braking in every situa-
tion, so do not rely on the FCA
to stop the vehicle in instances
where the driver sees an obsta-
cle 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 cancelind, 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.
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.
Collision Warning (1st warning)
The warning message appears onthe LCD display with the warning
alarms.
The FCA limitedly controls the brakes to mitigate a potential colli-
sion.
WARNING
Set or cancel FCA with control-
ling switches on steering wheel
after stopping the vehicle in the
safe place for your safety.
Do not attempt to set or cancel
the FCA while your vehicle is
moving.

Emergency braking (2nd warning)
The warning message appears onthe LCD display with the warning
alarms.
The FCA limitedly controls the brakes to mitigate a potential colli-
sion. Brake control is maximized
just before a 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 depress-
es the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
turns the steering wheel.
The braking control is automatical- ly canceled when risk factors dis-
appear.

CAUTION
When other warning soundssuch as the seat belt warningsound are in operation andoverride the FCA alarming sys-tem, FCA warning sounds maynot occur.
WARNING
The driver should always exer-
cise caution when operating the
vehicle, even though there is no
warning message or warning
alarm.
