Driving your vehicle

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.

Good braking practices

• Check to be sure the parking brake

is not engaged and 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
vehicle 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 vehicle 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 call an author-
ized Kia dealer for assistance.

• Don't coast down hills with the

vehicle out of gear. This is extreme-
ly hazardous. Keep the vehicle 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 danger-
ous because the brakes might
overheat and lose their effective-
ness. It also increases the wear of
the brake components.

• 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, don't let your vehicle
creep forward. To avoid creeping
forward, keep your foot firmly on
the brake pedal when the vehicle is
stopped.

• Be cautious when parking on a hill.

Firmly engage the parking brake
and place the shift lever in P (auto-
matic 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 vehicle 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 park-

ing brake can freeze in the
engaged position. This is most like-
ly 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 (automatic
transaxle) and block the rear
wheels so the vehicle cannot roll.
Then release the parking brake.

• Do not hold the vehicle on an

incline with the accelerator pedal.
This can cause the transaxle to
overheat. Always use the brake
pedal or parking brake.

6 51

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 ignition switch 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.

WARNING

-

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.

Collision Warning include the following:

6 53

Driving your vehicle

•

EARLY

-

When this condition is
selected, the initial
Forward Collision Warning
is activated earlier than
normal. This setting maxi-
mizes the amount of dis-
tance between the vehicle
or pedestrian ahead before
the initial warning occurs.

• NORMAL - When this condition is

selected, the initial
Forward Collision
Warning is activated nor-
mally. This setting allows
for a nominal amount of
distance between the
vehicle or pedestrian
ahead before the initial
warning occurs.

•

LATE

-

When this condition is

selected, the initial Forward
Collision Warning is activat-
ed later than normal. This
setting reduces the amount
of distance between the
vehicle or pedestrian ahead
before the initial warning
occurs.

Prerequisite for activation

The AEB will activate activated when
the AEB is selected on the LCD dis-
play, and when the following prereq-
uisites are satisfied:
- The ESC (Electronic Stability

Control) is activated.

- The driving speed is over 6 mph.

(The AEB only works within a cer-
tain range of vehicle speeds)

- When the AEB recognizes a vehi-

cle or the pedestrian in front. (The
AEB may not recognize every
obstacle or provide warnings and
braking in every situation, so do
not rely on the AEB to stop the
vehicle in instances where the driv-
er sees an obstacle and has the
ability to apply the brakes)

• The AEB automatically activates

when you turn the vehicle on.
The driver can deactivate the AEB
by canceling the in the system set-
ting on the LCD display.

• The AEB automatically deactivates

when canceling the ESC. When the
ESC is canceled, the AEB cannot
be activated on the LCD display.

WARNING

Set or cancel AEB with control-
ling switches on steering wheel
after stopping the vehicle in the
safe place for your safety.

AEB warning message and
system control

The AEB produces warning mes-
sages, warning alarms, and emer-
gency braking based on the level of
risk of a frontal collision, such as
when a vehicle ahead suddenly
brakes, when there is no following dis-
tance from the vehicle in front, or
when it detects a collision with a
pedestrian is imminent.

Forward Warning (1st warning)

The warning message appears on
the LCD display with the warning
alarms.

Collision Warning (2nd warning)

• The warning message appears on

the LCD display with the warning
alarms.

• The AEB applies the brakes within

certain limit to reduce the impact
from a collision.

Emergency braking (3

rd

warning)

• The warning message appears on

the 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 braking

system 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.

Sensor to detect the distance
from the vehicle in front
(front radar)

The sensor is to maintain a certain
distance from the vehicle in front.
However, the smudged sensor lens
with foreign substances, such as
snow and rain, adversely affects the
sensing performance. It may even
temporarily cancel the AEB. Always
keep the sensor lens clean.

Warning message and warning
light

When the sensor is covered or the
sensor lens is dirty with foreign sub-
stances, such as snow or rain, the
AEB operation may temporarily stop.
In this case, a warning message will
appear to notify 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 a license plate bracket or
bumper sticker near the sensor
area. Do not replace the bumper
by yourself. Doing so may adverse-
ly affect the sensing performance.

• Always keep the sensor/bumper

area clean.

• Use only a soft cloth to wash the

vehicle. Also, do not spray highly
pressurized water on the sensor
installed on the bumper.

• Be careful not to apply unneces-

sary force on the frontal sensor
area. When the sensor moves out
of the correct position due to
external force, the system may not
operate correctly even without the
warning light or message. In this
case, we recommend you to have
the vehicle inspected by an
authorized Kia dealer.

• Use only the genuine Kia sensor

cover. Do not arbitrarily apply
paint on the sensor cover.

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, we recommend
you to have the vehicle 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.

Limitations 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.

- 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.

- When driving on uneven surfaces

or roads with sudden gradient
changes.

- In construction sites, railroads, or

other metallic objects are on the
road.

6 59

Driving your vehicle

- Driving on a curve
The AEB performance decreases
while driving on a curve. The AEB
may not recognize the vehicle in front
even in the same lane. It may unnec-
essarily produce the warning mes-
sage and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
While driving on a curve, exercise
caution, and, if necessary, depress
the brake pedal.

While driving on a curve, the AEB
may recognize the vehicle in front in
the next lane. Exercise caution, and, if
necessary, depress the brake pedal.
Or, depress the accelerator pedal to
maintain the driving speed. Always,
take a look around the vehicle for
your safety.

- Driving on a slope
The AEB performance decreases
while driving upward or downward on
a slope, not recognizing the vehicle
in front in the same lane. It may
unnecessarily produce the warning
message and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
When the AEB suddenly recognizes
the vehicle in front while passing
over a slope, you may experience
sharp deceleration.
Always keep your eyes forward while
driving upward or downward on a
slope, and, if necessary, depress the
brake pedal.

- 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.

Recognizing pedestrians

- The pedestrian is not fully captured

by the camera sensor, or the
pedestrian does not walk in the
upright position.

- The pedestrian moves very fast.
- The pedestrian abruptly appears in

front.

- The pedestrian wears clothes sim-

ilar in color to the background.

- Conditions outside are too bright or

too dark.

- The vehicle drives at night or in the

darkness.

- There is an item similar in shape a

person’s body structure.

- The pedestrian is small.
- The pedestrian has impaired

mobility.

- The pedestrian blends in with their

surroundings.

- Sensor recognition is limited by

rain, snow, fog, etc.

- There is a group of pedestrians.

✽

✽

NOTICE

The system may temporarily cancel
due to the strong electric waves.

• Pay great caution to the vehicle in

front, when it has heavy loading
extended rearward, or when it has
higher ground clearance.

• The sensor only detects pedestri-

an, not carts, bicycles, motorcy-
cles, luggage bags, or strollers.

WARNING -

Testing the
AEB

The AEB does not operate in
certain situations. Thus, never
test-operate the AEB against a
person or an object. It may
cause a severe injury or even
death.

WARNING -

AEB and
Towing

Cancel the AEB in the User
Settings on the LCD display,

The cruise control system allows you
to program the vehicle to maintain a
constant speed without depressing
the accelerator pedal.
This system is designed to function
above approximately 20 mph (30
km/h).
If the cruise control is left on,
(CRUISE indicator light in the instru-
ment cluster illuminated) the cruise
control can be switched on acciden-
tally. Keep the cruise control system
off (CRUISE indicator light OFF)
when the cruise control is not in use,
to avoid inadvertently setting a speed.

Use the cruise control system only
when traveling on open highways in
good weather.
Do not use the cruise control when
driving in heavy or varying traffic, or
on slippery (rainy, icy or snow-cov-
ered) or winding roads or over 6%
up-hill or down-hill roads.

✽

✽

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 sec-
onds. This delay is normal.

• 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 condi-
tion.
