Driving your 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 fol-
low all the normal precautions for driv-
ing - including driving at safe speeds
for the conditions.
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.
✽ ✽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.

ESC OFF usage
When driving
ESC should be turned on for daily
driving 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.CAUTION
Driving with varying tire or
wheel sizes may cause the ESCsystem to malfunction. Whenreplacing tires, make sure theyare the same size as your origi-nal tires.
WARNING- Operating
ESC
Never press the ESC OFF but-
ton while ESC is operating (ESC
indicator light blinks).
If ESC is turned off while ESC is
operating, the vehicle may slip
out of control.WARNING- Electronic sta- bility control
Drive carefully even though
your vehicle has Electronic
Stability Control. It can only
assist you in maintaining con-
trol under certain circum-
stances.

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
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.
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 road. The split-mu road
is made of surfaces which have dif-
ferent 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
follow all the normal precautions
for driving at safe speeds for the
conditions – including driving in
clement 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.
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 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.

647
Driving your vehicle
Don't coast down hills with thevehicle 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) or in first or
reverse gear (manual 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) or in first or reverse gear
(manual transaxle) 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 transaxle
to overheat. Always use the brake
pedal or parking brake.

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 (10 km/h). (The AEB only works
within a certain 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
be activated on the LCD display.
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.
WARNING
Set or cancel AEB 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
AEB while your vehicle is mov-
ing.

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.
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.
WARNING
The AEB braking control cannot
completely stop the vehicle nor
avoid all collisions. The driver
should hold the responsibility
to safely drive and control the
vehicle.
WARNING
The AEB system logic operates
within certain parameters, such
as the distance from the vehicle
or pedestrian ahead, the speed
of the vehicle ahead, and the
driver's vehicle speed. Certain
conditions such as inclement
weather and road conditions
may affect the operation of the
AEB system.
WARNING
Never deliberately drive danger-
ously to activate the system.
