Driving your vehicle
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 begins
to roll, always depress the accelera-
tor pedal.
Good braking practices
Check to be sure the parking brakeis 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 Intelligent Variable Transmission /
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 (intel-
ligent variable transmission). If
your vehicle is facing downhill, turn
the front wheels into the curb to
help keep the vehicle from rolling.
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.

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, chock
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 (intelligent
variable transmission) and chock
the rear wheels so the vehicle can-
not roll. Then release the parking
brake.
Do not hold the vehicle on an incline with the accelerator pedal.
This can cause the transmission to
overheat. Always use the brake
pedal or parking brake.

Prerequisite for activation
The FCA gets ready to be activated
when the FCA is selected on the
LCD display, and when the following
prerequisites are satisfied.
- The ESC is ON.
- The driving speed is over 10 km/h(6 mph ). (However, FCA is activat-
ed within certain driving speed.)
- When recognizing a vehicle in front. (However, FCA deactivates
according to conditions in front and
vehicle systems, but it notices only
certain warnings.)
- The FCA automatically deactivates upon canceling the ESC. When the
ESC is cancelled, the FCA cannot
be activated on the LCD display. In
this situation, the FCA warning
light will illuminate.
FCA warning message and
system control
The FCA system produces warning
messages, warning alarms, and
emergency braking based on the risk
of a frontal collision, such as when a
vehicle ahead suddenly brakes.
The driver can select the initial warn-
ing activation time in the User Settings
in the LCD display. The options for the
initial Forward Collision-Avoidance
Assist include Early, Normal or Late
initial warning time.
WARNING
The FCA automatically acti-vates upon placing the igni-
tion switch to the ON position.
The driver can deactivate the
FCA by canceling the system
setting on the LCD display.
The FCA automatically deacti- vates upon canceling the
ESC. When the ESC is can-
celled, the FCA cannot be
activated on the LCD display.
The FCA warning light will
illuminate, but it does not indi-
cate a malfunction of the sys-
tem.
Set or cancel FCA with the control switches on the steer-
ing wheel after stopping the
vehicle in a safe place.

Collision Warning! (1st warning)
This warning message appears on
the LCD display with a warning
chime.
Additionally, the engine management
system intervenes to help decelerate
the vehicle.
- Your vehicle speed may decelerate
moderately.
- The FCA system limitedly controls the brakes to preemptively mitigate
impact from a collision.
Emergency braking! (2nd warning)
This warning message appears on
the LCD display with a warning
chime.
Additionally, the engine management
system intervenes to help decelerate
the vehicle.
- The FCA system limitedly controlsthe brakes to preemptively mitigate
impact from a collision. The brake
control is maximized just before a
collision.
Brake operation
In an emergency situation, the braking system enters in ready sta-
tus for prompt reaction upon the
driver depressing the brake pedal.
The FCA system provides addi- tional braking power for optimum
braking performance when the
driver depresses the brake pedal.
The braking control is automatical- ly deactivated when the driver
sharply depresses the accelerator
pedal or when the driver abruptly
operates the steering wheel.
The braking control is automatical- ly cancelled when risk factors dis-
appear.

(Continued)
The FCA system may activate
during braking and the vehicle
may stop suddenly. If this
occurs, any load in the vehicle
may endanger passengers.
Therefore, always be mindful
of the load volume in the vehi-
cle.
The FCA system may not acti- vate if the driver applies the
brake pedal to avoid the risk
of a collision.
The FCA system does not operate when the vehicle is in
reverse. In these cases, you
must maintain a safe braking
distance, and if necessary,
depress the brake pedal to
reduce the driving speed in
order to maintain a safe dis
tance.
(Continued)WARNING
The FCA is only a supplemen-tal system for the driver’s con-
venience. It is the driver's
responsibility to control the
vehicle. Do not solely depend
on the FCA system. Rather,
maintain a safe braking dis-
tance, and, if necessary,
depress the brake pedal to
lower the driving speed.
The FCA may unnecessarily produce the warning message
and the warning alarms. Also,
due to sensing limitations, the
FCA may not produce alarms
in certain situations. Read the
section “Limitation of the sys-
tem” for more information.
(Continued)
(Continued)
When there is a malfunctionwith the FCA, the FCA braking
control does not operate upon
detecting a collision risk even
with other braking systems
operating normally.
The FCA system only recog- nizes vehicles in front of it
while driving forward. It does
not identify any animals or
vehicles in the opposite direc-
tion.
The FCA cannot recognize cross-traffic or parked vehi-
cles presenting a side profile.
If the vehicle in front stops suddenly, you may have less
time to apply the brakes sys-
tem. Therefore, always keep a
safe distance between your
vehicle and the vehicle in
front of you.

Limitation of the system
The FCA system is designed to mon-
itor the vehicle ahead through cam-
era recognition to warn the driver
that a collision is imminent, and if
necessary, apply emergency brak-
ing. In certain situations, the camera
may not be able to detect the vehicle
ahead. In these cases, the FCA sys-
tem may not operate. The driver must
pay careful attention in the following
situations where the FCA operation
may be limited:
Recognizing vehicles
- The camera is contaminated withforeign substances.
- It heavily rains or snows.
- There is electromagnetic interfer- ence
- The vehicle in front has a narrow body. (i.e. motorcycles and bicy-
cles)
- The driver’s view is not clear due to backlight, reflected light, or dark-
ness.
- The camera cannot contain the full image of the vehicle in front.
- The vehicle in front is a special vehicle, such as a heavily-loaded
truck or a trailer.
- The outside brightness is greatly changed, such as entering/exiting
a tunnel.
- The vehicle driving is unstable.
- The camera sensor recognition is limited.
- The driver's field of view is not well illuminated (either too dark, too
much reflection, or too much back-
light that obscures the field of view)(Continued)
The regular braking functionwill operate normally even if
there is a problem with the
FCA brake control system or
other functions. In this case,
the braking control will not
operate in the risk of a colli-
sion.
The FCA system may not acti- vate in certain situations and
according to driving condi-
tion, traffic on the road,
weather, road conditions, etc.
The FCA system may not acti- vate in response to all types
of vehicles.

(including the headlights of vehi-
cles)
- Road sign, shadow on the road, tunnel entrances, toll gates, partial
pavement
- If the windshield has moisture on its surface or if the windshield
freezes,
- Driving in the fog.
- When objects are out of the sens- ing range of the camera - Driving on a curve
The FCA performance may be limit-
ed while driving on a curve. The FCA
may not recognize the vehicle in front
even if in the same lane. It may pro-
duce the warning message and the
warning alarm prematurely, or it may
not produce the warning message or
the warning alarm at all. When driv-
ing on a curve, exercise caution,
maintain a safe braking distance,
and if necessary, depress the brake
pedal to reduce your driving speed in
order to maintain a safe distance.

Driving your vehicle
The FCA system may recognize a
vehicle in an adjacent lane when driv-
ing on a curved road. In this situation,
the system may apply the brake.
Always pay attention to road and driv-
ing conditions while driving. If neces-
sary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance. Also, when
necessary, you may depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle. Always check the traffic
conditions around the vehicle.- Driving on a slope
The FCA performance may be limit-
ed while driving upward or downward
on a slope, and may not recognize a
vehicle in front in the same lane. It
may produce the warning message
and the warning alarm prematurely,
or it may not produce the warning
message and the warning alarm at
all.
When the FCA 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
When a vehicle changes lanes in
front of you, the FCA system may not
immediately detect the vehicle, espe-
cially if the vehicle changes lanes
abruptly. In this situation, you must
maintain a safe braking distance,
and if necessary, depress the brake
pedal to reduce your driving speed in
order to maintain a safe distance.

When driving in stop-and-go traffic,
and a stopped vehicle in front of you
merges out of the lane, the FCA sys-
tem may not immediately detect the
new vehicle that is now in front of
you. In this situation, you must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance. - Recognizing the vehicle
If the vehicle in front of you has cargo
that extends rearward from the cab,
or when the vehicle in front of you
has higher ground clearance, addi-
tional special attention is required.
The FCA system may not be able to
recognize the cargo extending from
the vehicle. In these instances, you
must maintain a safe braking dis-
tance from the rearmost object, and
if necessary, depress the brake
pedal to reduce your driving speed in
order to maintain a safe distance.

WARNING
Do not use the FCA system
when towing a vehicle. Cancel
the FCA in the User Settings
on the LCD display before
towing. Brake application by
the FCA system while towing
may adversely affect your
safety.
Use extreme caution when the vehicle in front of you has
cargo that extends rearward
from the cab, or when the
vehicle in front of you has
higher ground clearance.
The FCA system is designed to detect and monitor the
vehicle ahead through camera
recognition. It is not designed
to detect pedestrians, bicy-
cles, motorcycles, or smaller
wheeled objects such as lug-
gage bags, shopping carts, or
strollers.
