Driving your vehicle
Driving with varying tire or wheel
sizes may cause the ESC system to
malfunction. When replacing tires,
make sure they are the same size as
your original tires.ESC OFF usage
When driving
It’s a good idea to keep the ESCturned on for daily driving whenev-
er possible.
To turn ESC off while driving, press the ESC OFF button while driving
on a flat road surface.
Never press the ESC OFF button
while ESC is operating (ESC indica-
tor light blinks).
If ESC is turned off while ESC is
operating, the vehicle may slip out of
control.
Hill-start assist control (HAC)
Hill start Assist Control is a comfort
function. The main intent is to pre-
vent the vehicle from rolling back-
wards while driving uphill on an
inclined surface. HAC holds the brak-
ing pressure builtup by driver during
stopping procedure 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 dri-
ver’s intention to drive off.
WARNING - Operating ESC
Never press the ESC OFF but-
ton while ESC is operating.
If the ESC is turned off while
ESC is operating, the vehicle
may go out of control.
WARNING - Electronic
stability control
Drive carefully even though
your vehicle has Electronic
Stability Control. It can only
assist you in maintaining con-
trol under certain circum-
stances.

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 ESC is off but it does not acti-
vate when the ESC has malfunc-
tioned.
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 detected changes in coeffi-
cient of friction between right wheels
and left wheels when braking.
VSM operation
When the vehicle stability manage-
ment is operating properly, you can
feel a slight pulsation in the vehicle.
This is only the effect of brake control
and indicates nothing unusual. The VSM does not operate when:
Driving on bank road such as gra-
dient or incline
Driving rearward
ESC OFF indicator light ( ) remains on the instrument
cluster
EPS (Electronic Power Steering) indicator light remains on the
instrument clusterVSM 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 - 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.

Driving your vehicle
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.
The VSM is designed to functionabove approximately 9 mph (15
km/h) on curves.
The VSM is designed to function above approximately 18 mph (30
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 react 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
inclement weather and on a slip-
pery road.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 sys-
tem.

Good braking practices
Check to be sure the parking brake
is not engaged and that the park-
ing 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 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). 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 the upgrade with the accelerator
pedal. This can cause the transaxle
to overheat. Always use the brake
pedal or parking brake.

Driving your vehicle
The cruise control system allows you
to program the vehicle to maintain a
constant speed without depressing
the accelerator pedal.
This system is designed to function
above approximately 25 mph (40
km/h).
If the cruise control is left on,
(CRUISE indicator light in the instru-
ment cluster illuminated) the cruise
control can be switched on acciden-
tally. 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
driving in heavy or varying traffic, or
on slippery (rainy, icy or snow-cov-
ered) or winding 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 approx-
imately 3 seconds. This delay is
normal.
• 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 condi-
tion.
To set cruise control speed:
1.Press the CRUISE button on the
steering wheel to turn the system
on. The CRUISE indicator light in
the instrument cluster will illumi-
nate.
2.Accelerate to the desired speed, which must be more than 25 mph
(40 km/h).
CRUISE CONTROL SYSTEM (IF EQUIPPED)
WARNING - Misuse of
Cruise
Control
Do not use cruise control if the
traffic situation does not allow
you to drive safely at a constant
speed and with sufficient dis-
tance to the vehicle in front.

cruising speed will increase by 1.0
mph (2 km/h ) each time the lever is
operated in this manner.
To decrease the cruising
speed:
Follow either of these procedures:
Move the lever (1) down (to SET-)and hold it. Your vehicle will gradu-
ally slow down. Release the lever
at the speed you want to maintain.
Move the lever (1) down (to SET-) and release it immediately. The
cruising speed will decrease by 1.0
mph (2 km/h) each time the lever is
operated in this manner.

Driving your vehicle
To temporarily accelerate with
the cruise control on:
If you want to speed up temporarily
when the cruise control is on,
depress the accelerator pedal.
Increased speed will not interfere
with the cruise control operation or
change the set speed.
To return to the set speed, take your
foot off the accelerator.
To cancel cruise control, do
one of the following:
Depress the brake pedal.
Shift into N (Neutral) with an auto-matic transaxle.
Press the CANCEL switch.
Decrease the vehicle speed lower than the memory speed by 9 mph
(15 km/h).
Decrease the vehicle speed to less than approximately 25 mph (40
km/h).
Each of these actions will cancelcruise control operation (the SETindicator light in the instrument clus-ter will go off), but it will not turn thesystem off. If you wish to resumecruise control operation, move thelever up (to RES+). You will return toyour previously preset speed.

To resume cruising speed at
more than approximately 25
mph (40 km/h):
If any method other than the
CRUISE ON-OFF switch was used
to cancel cruising speed and the sys-
tem is still activated, the most recent
set speed will automatically resume
when you move the lever up.
It will not resume, however, if the
vehicle speed has dropped below
approximately 25 mph (40 km/h).
To turn cruise control off, do
one of the following:
Press the CRUISE button (the
CRUISE indicator light in the
instrument cluster will go off).
Turn the ignition off.
Both of these actions will cancel the cruise control operation. If you wantto resume the cruise control opera-tion, repeat the steps provided in “Toset cruise control speed” on the pre-vious page.
