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, 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.

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.
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.OJFA055275

The warning light illumi-
nates on the LCD display,
when you cancel the AEB
system. The driver can
monitor the AEB ON/OFF status on
the LCD display. When the warning
light remains ON with the AEB acti-
vated, have your vehicle inspected
by an authorized Kia dealer.

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.
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.
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 StabilityControl) 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
To avoid driver distractions, do
not attempt to set or cancel the
AEB while operating the vehicle.

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.

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.

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, have your 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, 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.
