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 detects changes in coeffi-
cient of friction between right wheels
and left wheels when braking.
VSM operation
When the VSM is in operation, ESC
indicator light ( ) blinks.
When the vehicle stability manage-
ment is operating properly, you can
feel a slight pulsation in the vehicle
and/or abnormal steering responses
(EPS- Electronic Power Steering).
This is only the effect of brake and
EPS control and indicates nothing
unusual.
The VSM does not operate when:
Driving on a sloping road such as a
gradient or incline
Driving in reverse
ESC OFF indicator light ( ) remains on the instrument cluster
EPS indicator 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 ( ) illuminates.
To turn on the VSM, press the button
again. The ESC OFF indicator light
goes out.
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 system.

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.
✽ ✽NOTICE
• The VSM is designed to function
above approximately 13 mph (22
km/h) on curves.
• The VSM is designed to function above approximately 6 mph (10
km/h) when a vehicle is braking on
a split-mu surface. A split-mu sur-
face is made of two surfaces which
have different 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 activate according to the driver’s intention,
even with installed VSM. Always fol-
low all the normal precautions for
driving at safe speeds for the condi-
tions – including driving in clement
weather and on a slippery road.
✽ ✽ NOTICE
For maximum protection, always
wear your seat belt. No system, no
matter how advanced, can compen-
sate for all driver error and/or driv-
ing conditions. Always drive respon-
sibly.
Hill-start assist control (HAC)
A vehicle has the tendency to roll
back on a steep hill when it starts to
go after stopping. The Hill-start
Assist Control (HAC) prevents the
vehicle from rolling back by applying
the brakes automatically for about 2
seconds. The brakes are released
when the accelerator pedal is
depressed or after about 2 seconds.
The HAC is activated only for about 2
seconds, so when the vehicle is
starting off always depress the accel-
erator pedal.
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
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. radar and camera), and, if nec-
essary, warns the driver of accident
risk with the warning message or the
warning alarms.✽ ✽NOTICE
Take the following precautions when
using the Autonomous Emergency
Braking (AEB):
• This system is only a supplemental
system and it is not intended to,
nor does it replace the need for
extreme care and attention of the
driver. The sensing range and
objects detectable by the sensors
are limited. Pay attention to the
road conditions at all times.
• NEVER drive too fast in accor- dance with the road conditions or
while cornering.
• Always drive cautiously to prevent unexpected and sudden situations
from occurring. AEB does not stop
the vehicle completely and does
not avoid collisions.
System setting and activation
System setting
The driver can activate the AEB by
placing the engine start/stop button
to the ON position and by selecting
'User Settings', 'Driving Assist', and
'Autonomous Braking System'. The
AEB deactivates, when the driver
cancels the system setting.

Autonomous Emergency
Braking (AEB) Limitations
The AEB system is a supple-
mental system and is not a sub-
stitute for safe driving prac-
tices. It is the responsibility of
the driver to always check the
speed and distance to the vehi-
cle ahead to ensure it is safety
to use the AEB system.OJFA055275

AUTONOMOUS EMERGENCY BRAKING (AEB)/ FORWARD COLLISION WARNING (FCW)
(IF EQUIPPED)

645
Driving your vehicle
Emergency braking (3rdwarning)
The warning message appears onthe LCD display with the warning
alarms.
The AEB controls the brakes with- in certain limit to release shock
from the collision.
The AEB controls the maximum
brakes just before the collision.
Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction against the dri-
ver’s depressing the brake pedal.
The AEB provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the brake pedal,
or when the driver abruptly turns
the steering wheel.
The braking control is automatical- ly canceled, when risk factors dis-
appear.
The driver should always exercise
caution when operating the vehicle,
even though there is no warning
message or warning alarm.
✽ ✽ NOTICE
The AEB operates in accordance
with the risk levels, such as the dis-
tance from the vehicle/passer-by in
front, the speed of the vehicle/pass-
er-by in front, and the driver's vehi-
cle operation. OJF055078L
WARNING
The AEB cannot avoid all colli-
sions. The AEB might not com-
pletely stop the vehicle before
collision, due to ambient weath-
er and road conditions. The
driver has the responsibility to
drive safely and control the
vehicle.

647
Driving your vehicle
System malfunction
When the AEB is not working prop-erly, the AEB warning light ( ) will
illuminate and the warning mes-
sage will appear for a few seconds.
After the message disappears, the
master warning light ( ) will illu-
minate. In this case, have your vehi-
cle inspected by an authorized Kia
dealer. The AEB warning message may
appear along with the illumination
of the ESC warning light. The AEB may unnecessarily pro-
duce warning messages and warn-
ing alarms. Due to the sensing lim-
itation, the AEB may not produce
warning messages or warning
alarm at all.
When there is a malfunction with the AEB, the braking control does
not operate upon detecting a colli-
sion risk even with other braking
systems normally operating.
The AEB operates only for the vehicle / pedestrian in front, while
driving forward. It does not operate
for any animals or vehicles in the
opposite direction.
The AEB can not recognize cross- traffic or parked vehicles present-
ing a side-profile.

WARNING
The AEB is only a supplemental
system for the driver’s conven-
ience.
The driver still maintains
responsibility to control the
vehicle. Do not solely depend
on the AEB system. Rather,
maintain a safe braking dis-
tance, and, if necessary,
depress the brake pedal to
lower the driving speed.

Limitation of the system
The AEB is an assistant system for a
driver in a certain risky driving condi-
tion and it does not take every
responsibility for all risks from driving
condition.
The AEB monitors the driving situa-
tions through the radar and the cam-
era sensor. For any vehicle activity
occurring outside the sensor range,
the AEB may not function. The driver
should exercise caution in the follow-
ing situations, as the AEB operation
may be limited:
Recognizing vehicles
- The radar or the camera is con-
taminated with foreign substances.
- It heavily rains or snows.
- There is electromagnetic interfer- ence.
- Something in the path of travel deflects the radar waves.
- The vehicle in front has a narrow body. (i.e. motorcycles and bicycles)
- The driver’s view is degraded by driving towards sunlight, reflected
light, or darkness.
- The camera cannot see the full profile of the vehicle in front.
- The vehicle in front is a special vehicle, such as a heavily-loaded
truck or a trailer.
- When driving on uneven surfaces or roads with sudden gradient
changes
- In construction sites, railroads, or other metalic objects are on the
road - The vehicle in front does not turn
ON the rear lights, does not have
rear lights, has asymmetric rear
lights, or has rear lights out of angle.
- The outside brightness is greatly changed, such as entering/exiting
the tunnel.
- The vehicle driving is unstable.
- The radar/camera sensor recogni- tion is limited.

- Changing lanes
Even though the vehicle in the next
lane enters into your lane, it may not
be recognized by the AEB, until it
enters the AEB sensing range.
Especially when the vehicle in the
next lane abruptly enters into your
lane, it is more likely not be recog-
nized. Always be attentive to driving
conditions. When the stopped vehicle in front
gets out of the lane, it may not be
recognized by your AEB. Always be
attentive to driving conditions.
- 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 haz-
ardous situation.

front 3. Move the lever down (to SET-),
and release it at the desired
speed. The set speed and vehicle
to vehicle distance on the LDC
screen will illuminate.
4. Release the accelerator pedal. The desired speed will automati-
cally be maintained.
If there is a vehicle in front of you, thespeed may decrease to maintain thedistance to the vehicle ahead.
On a steep grade, the vehicle mayslow down or speed up slightly whilegoing uphill or downhill.
(Continued)
- The sensing ability decreas-es if the level of front and
rear vehicle is changed from
the factory.
- Limited visibility (rain, snow, smog, etc)
- Cruise function should not be used when the vehicle is
being towed to prevent any
damage.
The advanced smart cruise control system cannot recog-
nize a stopped vehicle, pedes-
trians or an oncoming vehicle.
Always look ahead cautiously
to prevent unexpected and sud-
den situations from occurring.
Use the advanced smart cruise control system only when trav-
eling on open highways in
good weather conditions.
