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.
Driving your vehicle
7-34

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.
Emergency Stop Signal (ESS) (if
equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking the
stop light when the vehicle is braked
rapidly and severely. The system is activated when: • The vehicle suddenly stops (vehicle speed is over 55 km/h and the vehicle
deceleration at greater than 7 m/s 2
).
• The ABS is activating.
When the vehicle speed is under
40 km/h and the ABS deactivates or the sudden stop situation is over, the
stop light blinking will stop. Instead, the
hazard warning flasher will turn on au‐ tomatically. The hazard warning flasher will turn off
when vehicle speed is over 10 km/h af‐
ter the vehicle has stopped. Also, it will
turn off when the vehicle is driven at low speed for some time. You can turn
it off manually by pushing the hazard
warning flasher switch.
CAUTION
The Emergency Stop Signal (ESS)system will not work if the hazardwarning flasher is already on.
Good braking practices
WARNING
•Whenever you leave or park yourvehicle, always set the parkingbrake as far as possible and fullyengage the vehicle's transaxle intothe P (Park) position. If the parkingbrake is not fully engaged, the ve‐hicle may move inadvertently andinjure yourself and others.
(Continued)
(Continued)
•All vehicles should always have theparking brake fully engaged whenparking to avoid inadvertentmovement of the vehicle whichcan injure occupants or pedes‐trians.
• Check to be sure 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 vehicle is washed. Wet
brakes can be dangerous! Your vehi‐
cle 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 ve‐ hicle 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 we recommend that you call an authorized Kia dealer.

Driving your vehicle

• Do not coast down hills with the vehi‐cle 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 en‐
gine braking will help you maintain a
safe speed.
• Do not "ride" the brake pedal. Resting your foot on the brake pedal whiledriving 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 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 / Dual clutch
transmission, do not let your vehicle
creep forward. To avoid creeping for‐
ward, keep your foot firmly on the
brake pedal when the vehicle is stop‐
ped. • 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 vehi‐
cle 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 (Au‐
tomatic Transaxle / Dual clutch trans‐
mission) 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 up‐
grade with the accelerator pedal. This
can cause the transaxle to overheat.
Always use the brake pedal or park‐
ing brake.

AUTONOMOUS EMERGENCY BRAKING (AEB) (IF EQUIPPED)
The AEB system is to reduce or to
avoid accident risk. It recognizes the
distance from the vehicle ahead or the pedestrian through the sensors (i.e. ra‐
dar and camera), and, if necessary,
warns the driver of accident risk with the warning message or the warning
alarms.
WARNING
Take the following precautions whenusing the Autonomous EmergencyBraking (AEB):•This system is only a supplemen‐tal system and it is not intendedto, nor does it replace the need forextreme care and attention of thedriver. The sensing range and ob‐jects detectable by the sensors arelimited. Pay attention to the roadconditions at all times.
•NEVER drive too fast in accordancewith the road conditions or whilecornering.
(Continued)
(Continued)
•Always drive cautiously to preventunexpected and sudden situationsfrom occurring. AEB does not stopthe vehicle completely and doesnot avoid collisions.

Collision Warning is activa‐ted earlier than normal.This setting maximizesthe amount of distance
between the vehicle or
pedestrian ahead beforethe initial warning occurs.
NORMAL - When this condition is se‐
lected, the initial Forward
Collision Warning is activa‐ted normally. This settingallows for a nominalamount of distance be‐
tween the vehicle or pe‐
destrian ahead before theinitial warning occurs.
LATE - When this condition is se‐ lected, the initial Forward
Collision Warning is activa‐ted later than normal.
This setting reduces theamount of distance be‐
tween the vehicle or pe‐
destrian ahead before theinitial warning occurs.Prerequisite for activation
The AEB gets ready to be activated,when the AEB is selected on the LCD
display, and when the following prereq‐
uisites are satisfied.
- The ESC is activated.
- The driving speed is over 10 km/h.
(However, AEB is activated within
certain driving speed.)
- When recognizing the vehicle or the
pedestrian in front. (However, AEB
does not activate according to condi‐
tions in front and vehicle systems, but it notices only certain warnings.)
WARNING
•The AEB automatically activatesupon placing the ignition switch tothe ON position. The driver can de‐activate the AEB by canceling thesystem setting on the LCD display.
•The AEB automatically deactivatesupon canceling the ESC. When theESC is canceled, the AEB cannot beactivated on the LCD display.

AEB warning message and
system control
The AEB produces warning messages
and warning alarms in accordance with the collision risk levels of followings like
vehicle’s sudden braking in front or lack
of vehicle to vehicle distance or collision to pedestrians. Also, it controls the
brakes in accordance with the collision
risk levels.

• 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)

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 sensor cover or the sensor
lens is smudged with the foreign sub‐ stances, such as snow or rain, the AEB
operation may temporarily stop. In this
case, the warning message appears to warn the driver.
This is not a malfunction with the AEB.
To operate the AEB again, remove the
foreign substances.
NOTICE
•Do not install any accessories,
such as license plate molding or
sticker, on the sensor area. Nor ar‐
bitrarily replace the bumper.
Those may adversely affect the
sensing performance.
•Always keep the sensor/bumper
area clean.
•Use only soft clothes to wash the
vehicle. Also, do not spray highly
pressurized water on the sensor
installed on the bumper.
•Be careful not to apply unnecessa‐
ry force on the frontal sensor
area. When the sensor moves out
of the correct position due to ex‐
ternal force, the system may not
normally operate even without the
warning light or message. In this
case, we recommend you to have
the vehicle inspected by an au‐
thorized Kia dealer.
•Use only the genuine Kia sensor
cover. Do not arbitrarily apply
paint on the sensor cover.

• 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.
