• EPS (Electronic Power Steering) indi‐cator 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 (
) illu‐
minates.
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 indi‐
cates that a malfunction has been de‐
tected somewhere in the EPS (Elec‐ tronic Power Steering) system or VSM
system. If the ESC indicator light (
) or
EPS warning light remains on, we rec‐
ommend that the system be checked by an authorized Kia dealer.
NOTICE
•The VSM is designed to function
above approximately 22 km/h
(13 mph) on curves.
(Continued)
(Continued)
•The VSM is designed to function
above approximately 10 km/h
(6 mph) when a vehicle is braking
on a split-mu road. The split-mu
road is made of surfaces which
have different friction forces.
WARNING
•The Vehicle Stability Managementsystem is not a substitute for safedriving practices but a supplemen‐tary function only. It is the respon‐sibility of the driver to alwayscheck the speed and the distanceto the vehicle ahead. Always holdthe steering wheel firmly whiledriving.
•Your vehicle is designed to activateaccording to the driver’s intention,even with the VSM installed. Al‐ways follow all the normal precau‐tions for driving at safe speed forthe conditions – including driving ininclement weather and on a slip‐pery road.
(Continued)
(Continued)
•Driving with varying tire or wheelsizes may cause the VSM systemto malfunction. When replacingtires, make sure they are thesame size as your original tires.
Hill-start assist control (HAC) (if
equipped)
A vehicle has the tendency to slip back
on a steep hill when it starts to go af‐ ter stopping. The Hill-start Assist Con‐
trol (HAC) prevents the vehicle from
slipping back by operating the brakes automatically for about 1~2 seconds.
The brakes are released when the ac‐
celerator pedal is depressed or after about 1~2 seconds.
WARNING
The HAC is activated only for about1~2 seconds, so when the vehicle isstarting off always depress the ac‐celerator pedal.

• The AEB provides additional brakingpower for optimum braking perform‐
ance, when the driver depresses the brake pedal.
• The braking control is automatically deactivated, when the driver sharply
depresses the brake pedal, or when
the driver abruptly operates the
steering wheel.
• The braking control is automatically canceled, when risk factors disappear.
CAUTION
The driver should always pay greatcaution to vehicle operation, eventhough there is no warning messageor warning alarm.
WARNING
The AEB cannot avoid all collisions.The AEB might not completely stopthe vehicle before collision, due toambient, weather and road condi‐tions. The driver has the responsibili‐ty to drive safely and control the ve‐hicle.
WARNING
The AEB operates in accordance withthe risk levels, such as the distancefrom the vehicle/passer-by in front,the speed of the vehicle/passer-byin front, and the driver's vehicle op‐eration.
Sensor to detect the distance
from the vehicle in front (front
radar)
0+')1
The sensor is to maintain a certain dis‐
tance from the vehicle in front. Howev‐ er, the smudged sensor lens with for‐
eign substances, such as snow and rain,
adversely affects the sensing perform‐ ance. It may even temporarily cancel
the AEB. Always keep the sensor lens
clean.

• When the AEB is not working proper‐ly, the AEB warning light () will illu‐
minate and the warning message will appear for a few seconds. After the
message disappears, the master
warning light (
) will illuminate. In
this case, we recommend you to have the vehicle inspected by an author‐
ized Kia dealer.
• The AEB warning message may ap‐ pear along with the illumination of
the ESC warning light.
WARNING
•The AEB is only a supplementalsystem for the driver’s conven‐ience. The driver should hold theresponsibility to control the vehicleoperation. Do not solely depend onthe AEB system. Rather, maintaina safe braking distance, and, ifnecessary, depress the brake ped‐al to lower the driving speed.
(Continued)
(Continued)
•The AEB may unnecessarily pro‐duce the warning message and thewarning alarms. Also, due to thesensing limitation, the AEB maynot produce the warning messageand the warning alarm at all.
•When there is a malfunction withthe AEB, the braking control doesnot operate upon detecting a colli‐sion risk even with other brakingsystems normally operating.
•The AEB operates only for the ve‐hicle / pedestrian in front, whiledriving forward. It does not oper‐ate for any animals or vehicles inthe opposite direction.
•The AEB does not recognize thevehicle, which horizontally drivesacross the crossroad, or the vehi‐cle, which is parked in the horizon‐tal direction.
Limitation of the system
The AEB is an assistant system for a
driver in a certain risky driving condition
and it does not take every responsibili‐ ty for all risks from driving condition. The AEB monitors the driving situations
through the radar and the camera sen‐
sor. Thus, for a situation out of the sensing range, the AEB may not nor‐
mally operate. The driver should pay
great caution in the following situa‐ tions. The AEB operation may be limi‐
ted.
Recognizing vehicles
- The radar or the camera is contami‐
nated with foreign substances.
- It heavily rains or snows.
- There is interruption by electric
waves.
- There is severe irregular reflection
from the radar.
- The vehicle in front has a narrow
body. (i.e. motor cycle and bicycle)
- The driver’s view is unclear due to
the backlight, the reflected light, or
darkness.
- The camera cannot contain the full
image of the vehicle in front.

-Changing lanes
Even though the vehicle in the next
lane enters into your lane, it may not
be recognized by the AEB, until it en‐ ters the AEB sensing range.
Especially when the vehicle in the
next lane abruptly enters into your
lane, it is more likely not to be recog‐
nized. Always pay great attention.
0+'
When the stopped vehicle in front
gets out of the lane, it may not be
recognized by your AEB. Always pay great attention.
0+'
- Recognizing the vehicle
When the vehicle in front has heavy
loading extended rearward, or when
the vehicle in front has higher ground clearance, it may induce a hazardous
situation.
Recognizing pedestrians
- The pedestrian is not fully captured
by the camera sensor, or the pedes‐
trian does not walk in the upright po‐ sition.
- The pedestrian moves very fast.
- The pedestrian abruptly appears in
front.
- The pedestrian wears clothes in the
color similar to the background.
- The outside is too bright or too dark.
- The vehicle drives at night or in the
darkness.
- There is an item similar to a person’s
body structure.
- The pedestrian is small.
- The pedestrian has impaired mobility.
- It is difficult to distinguish the pedes‐
trian from the surroundings.
- The sensor recognition is limited.

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 is illumina‐ted), the cruise control can beswitched on accidentally. Keep thecruise control system off whenthe cruise control is not in use, toavoid inadvertently setting aspeed.
•Use the cruise control system onlywhen traveling on open highwaysin good weather.
•Do not use the cruise control whenit may not be safe to keep the ve‐hicle at a constant speed, for in‐stance, driving in heavy or varyingtraffic, or on slippery (rainy, icy orsnow covered) or winding roads orover 6% up-hill or down-hill roads.
•Pay particular attention to thedriving conditions whenever usingthe cruise control system.
(Continued)

•Be careful when driving downhillusing the cruise control system,which may increase the vehiclespeed.
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 oper‐
ation, when the SET switch is acti‐
vated or reactivated after applying
the brakes, the cruise control will
energize after approximately 3

Operation
0+'-
• If a traffic sign that is relevant toyour vehicle is passed, the system
displays the information of the speed limits and no passing restrictions to
the driver.
• When the driver turns on the ignition, the system displays stored informa‐
tion of the speed limit before turning
off the ignition. • Sometimes different speed limits are
displayed for the same road. The in‐
formation displayed is depending on
the situation. Because, traffic signs
with additional sign (e.g rainy, ar‐
row...) are also detected and com‐ pared with vehicle interior data (e.g
wiper operation, turn signal...).
• The system can update the speed limit information without visible
speed limit signs in the following sit‐ uations. - When you change your driving di‐ rection with right or left or U turn‐ ing.
- When vehicle changes roads. (e.g. from highway to country road…)
- When you enter or exit into town or village.
NOTICE
If speed limit value has the differ‐
ence between cluster and naviga‐
tion, check the speed unit setting in
navigation.

LANE KEEPING ASSIST SYSTEM (LKAS) (IF EQUIPPED)
05'4
The Lane Keeping Assist System de‐
tects lane markers on the road, and as‐ sists the driver’s steering to help keep
the vehicle between lanes. When the system detects the vehicle
straying from its lane, it alerts the driv‐
er with a visual and audible warning, while applying a slight counter steering
torque, trying to prevent the vehicle
from moving out of its lane.
WARNING
•The steering wheel is not continu‐ously controlled so if the vehiclespeed is very fast when leaving alane the vehicle may not be con‐trolled by the system.
•The operation of the LKAS can beaffected by several factors (in‐cluding environmental conditions).It is the responsibility of the driverto pay attention to the roadwayand to maintain the vehicle in itslane at all times.
•Do not steer the steering wheelsuddenly when the steering wheelis being assisted by the system.
(Continued)
(Continued)
•LKAS prevents the driver frommoving out of the lane uninten‐tionally by assisting the driver'ssteering. However, the drivershould not solely rely on the sys‐tem but always pay attention onthe steering wheel to stay in thelane.
•Always check the road conditionand surroundings and be cautiouswhen the system cancels, doesnot operate or malfunctions.
•Do not place any accessories,stickers or tint the windshield nearthe rearview mirror.
•The system detects lane markersand controls the steering wheel bya camera, therefore, if the lanemarkers are hard to detect, thesystem may not work properly.Please refer to L
