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.

ESC OFF usage
When driving
ESC should be turned on for dailydriving whenever possible.
To turn ESC off while driving, press the ESC OFF button while driving
on a flat road surface.
✽ ✽ 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.
WARNING- Operating

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.

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 22 km/h (13
mph) on curves.
• The VSM is designed to function above approximately 10 km/h (6
mph) 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 / Dual clutch
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 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 ignition switch 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.
