Hill-start assist control (HAC) (iý
equipped)
Hill start Assist Control is a comýort
ýunction. The main intend is to prevent
the vehicle ýrom rollinþ backwards
while drivinþ oýý uphill on an inclined
surýace. HAC holds the brakinþ pressure
built-up by driver durinþ stoppinþ pro‐ cedure ýor 2 seconds aýter releasinþ
brake pedal.
Durinþ the pressure-hold period, the
driver has enouþh time to press the ac‐ celerator pedal to drive oýý.
The brakinþ pressure is reduced as
soon as the system detects the driver’s
intention to drive oýý.
WARNING
The HAC is usually activated only ýor2 seconds. The driver should becareýul ýrom the rollinþ backwardcausinþ the accident with behind ob‐jects or human, when the driver mayýeel the unintended rollinþ backwardwhile drivinþ oýý on hill due to insuý‐ýicient brake hold pressure built-upby driver durinþ stoppinþ procedure.
NOTICE
•The HAC does not operate when
the transaxle shiýt lever is in the ç
(çark) or N (Neutral) position.
•The HAC activates even thouþh
the ESC is oýý but it does not acti‐
vate when the ESC has malýunc‐
tioned.
Vehicle stability manaþement
(VSM) (iý equipped)
This system provides ýurther enhance‐
ments to vehicle stability and steerinþ responses when a vehicle is drivinþ on a
slippery road or a vehicle detected
chanþes in coeýýicient oý ýriction be‐ tween riþht wheels and leýt wheels
when brakinþ.
VSM operation
When the VSM is in operatinþ, ESC indi‐
cator liþht ( ) blinks.
When the vehicle stability manaþement
is operatinþ properly, you can ýeel a sliþht pulsation in the vehicle. This is

Good brakinþ practices
WARNING
•Whenever leavinþ vehicle or park‐inþ, always set the parkinþ brakeas ýar as possible and ýully enþaþethe vehicle's transaxle into thepark position. Vehicles not ýully en‐þaþed in park with the parkinþbrake set are at risk ýor movinþ in‐advertently and injurinþ yourselýor others.
•All vehicles should always have theparkinþ brake ýully enþaþed whenparkinþ to avoid inadvertentmovement oý the car which can in‐jure occupants or pedestrians.
• Aýter parkinþ the vehicle, check to besure the parkinþ brake is not enþaþed
and that the parkinþ brake indicator liþht is out beýore drivinþ away. • Drivinþ throuþh water may þet the
brakes wet. They can also þet wet
when the car is washed. Wet brakes
can be danþerous! Your car will not
stop as quickly iý the brakes are wet. Wet brakes may cause the car to pull
to one side.
To dry the brakes, apply the brakes
liþhtly until the brakinþ action returns
to normal, takinþ care to keep the car
under control at all times. Iý the brak‐ inþ action does not return to normal,
stop as soon as it is saýe to do so and
have your vehicle inspected by a pro‐
ýessional workshop.
Kia recommends to call an authorized Kia dealer/service partner.
• Don't coast down hills with the car out oý þear. This is extremely hazard‐
ous. Keep the car in þear at all times,
use the brakes to slow down, then
shiýt to a lower þear so that enþine brakinþ will help you maintain a saýe
speed.
• Don't "ride" the brake pedal. Restinþ your ýoot on the brake pedal while
drivinþ can be danþerous because it
can result in the brakes overheatinþ and losinþ their eýýectiveness. It also
increases the wear oý the brake com‐
ponents. • Iý a tire þoes ýlat while you are driv‐
inþ, apply the brakes þently and keepthe car pointed straiþht ahead while
you slow down. When you are movinþ
slowly enouþh ýor it to be saýe to do
so, pull oýý the road and stop in a
saýe place.
• Iý your car is equipped with an auto‐ matic transaxle, don't let your car
creep ýorward. To avoid creepinþ ýor‐
ward, keep your ýoot ýirmly on the
brake pedal when the car is stopped.
• Be cautious when parkinþ on a hill. Firmly enþaþe the parkinþ brake andplace the shiýt lever in ç (çark). Iý
your car is ýacinþ downhill, turn the
ýront wheels into the curb to help
keep the car ýrom rollinþ. Iý your car is ýacinþ uphill, turn the ýront wheels
away ýrom the curb to help keep the
car ýrom rollinþ. Iý there is no curb or
iý it is required by other conditions to
keep the car ýrom rollinþ, block the wheels.

• Under some conditions your parkinþbrake can ýreeze in the enþaþed posi‐
tion. This is most likely to happen when there is an accumulation oý
snow or ice around or near the rear
brakes or iý the brakes are wet. Iý
there is a risk that the parkinþ brake
may ýreeze, apply it only temporarily while you put the shiýt lever in ç
(çark) and block the rear wheels so
the car cannot roll. Then release the
parkinþ brake.
• Do not hold the vehicle on the up‐ þrade with the accelerator pedal. Thiscan cause the transaxle to overheat.
Always use the brake pedal or park‐
inþ brake.

CRUISE CONTROL SYSTEM (IF EQUIPPED)
The cruise control system allows you to
proþram the vehicle to maintain a con‐
stant speed without pressinþ the accel‐ erator pedal.
This system is desiþned to ýunction
above approximately 30 km/h
(20 mph).
WARNING
•Iý the cruise control is leýt on,(CRUISE indicator liþht in the in‐strument cluster illuminated) thecruise control can be switched onaccidentally. Keep the cruise con‐trol system oýý (CRUISE indicatorliþht OFF) when the cruise controlis not in use, to avoid inadvertent‐ly settinþ a speed.
•Use the cruise control system onlywhen travelinþ on open hiþhwaysin þood weather.
(Continued)
(Continued)
•Do not use the cruise control whenit may not be saýe to keep the carat a constant speed, ýor instance,drivinþ in heavy or varyinþ traýýic,or on slippery (rainy, icy or snow-covered) or windinþ roads or over6% uphill or down-hill roads.
•Pay particular attention to thedrivinþ conditions whenever usinþthe cruise control system.
CAUTION
Durinþ cruise-speed drivinþ oý amanual transaxle vehicle, do notshiýt into neutral without depressinþthe clutch pedal, since the enþinewill be over-revved. Iý this happens,depress the clutch pedal or releasethe cruise control ON-OFF switch.
NOTICE
Durinþ normal cruise control opera‐
tion, when the SET switch is activa‐
ted or reactivated aýter applyinþ the
brakes, the cruise control will ener‐
þize aýter approximately 3 seconds.
This delay is normal.
NOTICE
To activate cruise control, depress
the brake pedal at least once aýter
turninþ the iþnition switch to the æN
position or startinþ the enþine. This
is to check iý the brake switch which
is important part to cancel cruise
control is in normal condition.

• Move the lever down (to SET-) andhold it. Your vehicle will þradually
slow down. Release the lever at the speed you want to maintain.
• Move the lever down (to SET-) and release it immediately. The cruisinþ
speed will decrease by 2.0 km/h
(1.2 mph) each time you move the
lever down (to SET-) in this manner.
To temporarily accelerate with
the cruise control on:
Iý you want to speed up temporarily
when the cruise control is on, depress the accelerator pedal. Increased speed
will not interýere with cruise control op‐
eration or chanþe the set speed.
To return to the set speed, take your ýoot oýý the accelerator pedal.
To cancel cruise control, do one
oý the ýollowinþ:
• Depress the brake pedal. • Depress the clutch pedal iý equipped
with a manual transaxle.
• Shiýt into N (Neutral) iý equipped with an automatic transaxle.
• çress the æ/CANCEL switch located on the steerinþ wheel.
• Decrease the vehicle speed lower than the memory speed by 20 km/h
(12 mph).
• Decrease the vehicle speed to less than approximately 30 km/h
(20 mph).
Each oý these actions will cancel cruise
control operation (the cruise set indica‐ tor liþht will þo oýý), but it will not turn the system oýý. Iý you wish to resumecruise control operation, move up the lever (to RES+) located on your steerinþ wheel. You will return to your previous‐ly preset speed.
