NOTICE
•When operating the vehicle on a
dynamometer, ensure that the
ESC is turned off (ESC OFF light il‐
luminated).
•Turning the ESC off does not af‐
fect ABS or brake system opera‐
tion.
WARNING
Never press the ESC OFF buttonwhile ESC is operating.If the ESC is turned off while ESC isoperating, the vehicle may go out ofcontrol.To turn ESC off while driving, pressthe ESC OFF button while driving ona flat road surface.
Hill-start assist control (HAC) (if
equipped)
Hill start Assist Control is a comfort
function. The main intend is to prevent the vehicle from rolling backwards
while driving off uphill on an inclined
surface. HAC holds the braking pressure
builtup by driver during stopping proce‐ dure for 2 seconds after releasing
brake pedal.
During the pressure-hold period, the
driver has enough time to press the ac‐ celerator pedal to drive off.
The braking pressure is reduced as
soon as the system detects the driver’s
intention to drive off.
WARNING
The HAC is usually activated only for2 seconds. The driver should becareful from the rolling backwardcausing the accident with behind ob‐jects or human, when the driver mayfeel the unintended rolling backwardwhile driving off on hill due to insuf‐ficient brake hold pressure built-upby driver during stopping procedure.
NOTICE
•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) (if equipped)
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 be‐ tween right wheels and left wheels
when braking.
VSM operation
When the VSM is in operation, ESC 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 in‐
dicates nothing unusual.

Good braking practices
WARNING
•Whenever leaving vehicle or park‐ing, always set the parking brakeas far as possible and fully engagethe vehicle's transaxle into thepark position. Vehicles not fully en‐gaged in park with the parkingbrake set are at risk for moving in‐advertently and injuring yourselfor others.
•All vehicles should always have theparking brake fully engaged whenparking to avoid inadvertentmovement of the car which can in‐jure occupants or pedestrians.
• After parking the vehicle, check to besure the parking brake is not engaged
and that 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 car is washed. Wet brakes
can be dangerous! Your car will not
stop as quickly if the brakes are wet. Wet brakes may cause the car 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 car
under control at all times. If the brak‐ ing action does not return to normal,
stop as soon as it is safe to do so and
have your vehicle inspected by a pro‐
fessional workshop.
Kia recommends to call an authorized Kia dealer/service partner.
• Don't coast down hills with the car out of gear. This is extremely hazard‐
ous. Keep the car 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 dangerous because it
can result in the brakes overheating and losing their effectiveness. It also
increases the wear of the brake com‐
ponents. • If a tire goes flat while you are driv‐
ing, apply the brakes gently and keepthe car 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 car is equipped with an auto‐ matic transaxle, don't let your car
creep forward. To avoid creeping for‐
ward, keep your foot firmly on the
brake pedal when the car is stopped.
• Be cautious when parking on a hill. Firmly engage the parking brake andplace the shift lever in P (Park). If
your car is facing downhill, turn the
front wheels into the curb to help
keep the car from rolling. If your car is facing uphill, turn the front wheels
away from the curb to help keep the
car from rolling. If there is no curb or
if it is required by other conditions to
keep the car from rolling, block the wheels.

Driving your vehicle

• Under some conditions your parkingbrake 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
(Park) and block the rear wheels so
the car cannot roll. Then release the
parking brake.
• Do not hold the vehicle on the up‐ grade with the accelerator pedal. Thiscan cause the transaxle to overheat.
Always use the brake pedal or park‐
ing brake.

CRUISE CONTROL SYSTEM (IF EQUIPPED)
The cruise control system allows you to
program the vehicle to maintain a con‐
stant speed without pressing the accel‐ erator pedal.
This system is designed to function
above approximately 30 km/h (20
mph).
WARNING
•If the cruise control is left on,(CRUISE indicator light in the in‐strument cluster illuminated) thecruise control can be switched onaccidentally. Keep the cruise con‐trol system off (CRUISE indicatorlight OFF) when the cruise controlis not in use, to avoid inadvertent‐ly setting a speed.
•Use the cruise control system onlywhen traveling on open highwaysin good weather.
(Continued)
(Continued)
•Do not use the cruise control whenit may not be safe to keep the carat a constant speed, for instance,driving in heavy or varying traffic,or on slippery (rainy, icy or snow-covered) or winding roads or over6% uphill or down-hill roads.
•Pay particular attention to thedriving conditions whenever usingthe cruise control system.
CAUTION
During cruise-speed driving of amanual transaxle vehicle, do notshift into neutral without depressingthe clutch pedal, since the enginewill be over-revved. If this happens,depress the clutch pedal or releasethe cruise control ON-OFF switch.
NOTICE
During normal cruise control opera‐
tion, when the SET switch is activa‐
ted or reactivated after applying the
brakes, the cruise control will ener‐
gize 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.
