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 Automatic 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 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.

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 (Electronic StabilityControl) is activated.
- Vehicle speed is over 5 mph (8 km/h). (The FCA is only activated
within a certain speed range.)
- The system detects a vehicle or pedestrian in front, which may col-
lide with your vehicle. (The FCA
may not be activated or may sound
a warning alarm in accordance
with the driving situation or vehicle
condition.)
❈ The FCA may not operate properly
according to the frontal situation,
the direction and speed of pedes-
trian.
FCA warning message and
system control
The FCA system produces warning
messages, warning alarms, and
emergency braking based on the
level of 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 Warning include Early,
Normal or Late initial warning time.
WARNING
Completely stop the vehicle
on a safe location before
operating the switch on the
steering wheel to activate/
deactivate the FCA system.
The FCA automatically acti- vates upon placing the Engine
Start/Stop button to the ON
position. The driver can deac-
tivate the FCA by canceling
the system setting on the LCD
display. To avoid driver dis-
tractions, do not attempt to
set or cancel the FCA while
driving the vehicle.
The FCA automatically deac- tivates upon canceling the
ESC (Electronic Stability
Control). When the ESC is
canceled, the FCA cannot be
activated on the LCD display.
The FCA warning light will
illuminate, but it does not
indicate a malfunction of the
system.

Collision Warning (1st warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs by the
engine management system to help
decelerate the vehicle.
- Your vehicle speed may decelerate
moderately.
- The FCA system limitedly controls the brakes to preemptively mitigate
impact in a collision. - It will operate if the vehicle speed is
greater than 5 mph (8 km/h) and
less than or equal to 38 mph (60
km/h) on a forward vehicle.
(Depending on the condition of the
vehicle ahead and the environment
surrounding it, the possible maxi-
mum operating speed may be
reduced.)
Emergency braking (2nd warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs by the
engine management system to help
decelerate the vehicle.
- The FCA system limitedly controlsthe brakes to preemptively mitigate
impact in a collision. The brake
control is maximized just before a
collision.

Warning message and warninglight
When the sensor is blocked with dirt,
snow, or debris, the FCA system
operation may stop temporarily.
If this occurs, a warning message will
appear on the LCD display.
The system will operate normally
when such dirt, snow or debris is
removed.
However, the FCA system may not
properly operate in an area (e.g.
open terrain), where any substances
are not detected after turning ON the
engine. Although a warning message will not
appear on the LCD display, the FCA
may not properly operate.
System malfunction
When the FCA is not working prop-
erly, the FCA 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 the vehi-
cle inspected by an authorized Kia
dealer.
The FCA warning message may appear along with the illumination
of the ESC warning light.OQL058372N

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 operation. Do not
solely depend on the FCA
system. Rather, maintain a
safe braking distance, and, if
necessary, depress the brake
pedal to reduce the driving
speed or stop the vehicle.
In certain instances and under certain driving condi-
tions, the FCA system may
activate unintentionally.
Also, due to sensing limita-
tions, in certain situations,
the front radar sensor or front
view camera recognition sys-
tem may not detect the vehi-
cle or pedestrians ahead. The
FCA system may not activate
and the warning message
may not be displayed.
