Driving your vehicle
The ABS warning light will stay on for
approximately 3 seconds after the igni-
tion switch 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 but your regular
brakes will work normally. Contact an
authorized Kia dealer as soon as possi-
ble. When you drive on a road with poor
traction, such as an icy road, and oper-
ated your brakes continuously, the
ABS will be active continuously and the
ABS warning light may illuminate. Pull
your vehicle over to a safe place and
stop the engine.
Restart the engine. If the ABS warning light is off, then your ABS 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 the 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 stabilize the vehi-
cle 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 hydroplan-
ing on wet surfaces can still result in seri-
ous 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 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 conditions. It is not a sub-
stitute for safe driving practices. Factors
including speed, road conditions and
driver steering input can all affect
whether ESC will be effective in prevent-
ing a loss of control. It is still your respon-
sibility to drive and corner at reasonable
speeds and to leave a sufficient margin
of safety.When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ESC is active.

Hill-start assist control (HAC)
Hill start Assist Control works to prevent
the vehicle from rolling backwards while
driving from a stop on an inclined sur-
face. HAC holds the braking pressure
built up during stopping. The brakes are
held for 2 seconds after releasing brake
pedal.
During the pressure-hold period, the
driver has enough time to press the
accelerator pedal to drive off.
The braking pressure is reduced as soon
as the system detects the driver’s inten-
tion to drive off. The HAC does not operate when the
transaxle shift lever is in the P (Park) or
N (Neutral) position.
The HAC activates even though the ESP is off but it does not activate when
the ESP has malfunctioned.WARNING - Operating ESC
Never press the ESC OFF button
while ESC is operating.
If the ESC is turned off while ESC is
operating, the vehicle may go out of
control.
WARNING - Activating
HAC
Drivers should pay close attention
when activating the HAC. The vehi-
cle may roll backward causing an
accident due to insufficient brake
hold pressure.

Vehicle stability management
(VSM)
This system provides further enhance-
ments to vehicle stability and steering
responses when a vehicle is driving on a
slippery road or a vehicle detected
changes in coefficient of friction between
right wheels and left wheels when brak-
ing.
VSM operation
When the VSM is in operation, ESP indi-
cator light ( ) blinks.
When the vehicle stability management
is operating properly, you can feel a slight
pulsation in the vehicle. This is only the
effect of brake control and indicates noth-
ing unusual. The VSM does not operate when:
Driving on bank road such as gradient
or incline
Driving rearward
ESP 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 ( ) illumi-
nates.
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 press-
ing the ESC OFF button. It indicates that
a malfunction has been detected some-
where in the Electric Power Steering sys-
tem or VSM system. If the ESC indicator
light ( ) or ESC warning light remains
on, take your vehicle to an authorized Kia
dealer and have the system checked.
The VSM is designed to function aboveapproximately 15 km/h (9 mph) on
curves.
The VSM is designed to function above approximately 30 km/h (18 mph) when
a vehicle is braking on a split-mu road.
The split-mu road is made of surfaces
which have different friction forces.

Driving your vehicle
The Vehicle Stability Management sys-tem is not a substitute for safe driving
practices but a supplementary function
only. It is the responsibility of the driver
to always check the speed and the dis-
tance 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 – includ-
ing driving inclement weather and on a
slippery road.Good braking practices
Check to be sure the parking brake isnot engaged and that the parking
brake indicator light is out before driv-
ing 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 extremely haz-
ardous. 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 driv-
ing can be dangerous because the
brakes might overheat and lose their
effectiveness. It also increases the
wear of the brake components.
If a tire goes flat while you are driving, 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 vehi-
cle creep forward. To avoid creeping
forward, keep your foot firmly on the
brake pedal when the vehicle is
stopped.
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.

Be cautious when parking on a hill.
Firmly engage the parking brake and
place the shift lever in P (automatic
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 parking brake can freeze in the engaged posi-
tion. This is most likely 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.

527
Driving your vehicle
The cruise control system allows you to
program the vehicle to maintain a con-
stant speed without depressing the
accelerator pedal.
This system is designed to function
above approximately 40 km/h (25 mph).
If the cruise control is left on, (CRUISE
indicator light in the instrument cluster
illuminated) the cruise control can be
switched on accidentally. 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 driv-
ing in heavy or varying traffic, or on slip-
pery (rainy, icy or snow-covered) or wind-
ing roads or over 6% up-hill or down-hill
roads.✽ ✽NOTICE
During normal cruise control operation,
when the SET switch is activated or
reactivated after applying the brakes,
the cruise control will energize after
approximately 3 seconds. This delay is
normal.
✽ ✽NOTICE
To activate cruise control, depress the
brake pedal at least once after turning
the ignition switch to the ON position or
starting the engine. This is to check if
the brake switch which is important
part to cancel cruise control is in normal
condition.
To set cruise control speed:
1. Press the CRUISE ON-OFF button on
the steering wheel to turn the system
on. The CRUISE indicator light in the
instrument cluster will illuminate.
2. Accelerate to the desired speed, which must be more than 40 km/h (25 mph).
CRUISE CONTROL SYSTEM (IF EQUIPPED)
WARNING - Misuse cruise
control
Do not use cruise control if the traf-
fic situation does not allow you to
drive safely at a constant speed
and with sufficient distance to the
vehicle in front.
