Forward Collision-Avoidance Assist
system is designed to detect the
vehicle, a pedestrian or cyclist ahead (if
equipped) in the roadway through front
radar signals and front view camera
recognition to warn the driver that a
collision is imminent, and if necessary,
apply emergency braking.
WARNING
Take the following precautions when
using Forward Collision-Avoidance
Assist system: • 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.
• Drive at posted speed limits and
accordance to road conditions.
• Always drive cautiously to prevent
unexpected and sudden situations
from occurring. FCA does not always
stop the vehicle completely.

Warning Timing
• Selecting Warning Timing
The driver can select the initial
warning activation time from the
User Settings in the LCD display
or infotainment system display (if
equipped) by selecting ‘User Settings
→ Driver Assistance → Warning Timing
→ Normal/Late’.
The options for the initial Forward
Collision Warning includes the following: - Normal: When this option is selected, the
initial Forward Collision Warning
is activated sensitively. If you feel
the warning activates too early, set
Forward Collision Warning to ‘Later’.
Even though, ‘Normal’ is selected if
the front vehicle suddenly stops the
initial warning activation time may not
seem fast. - Late:
When this option is selected, the initial
Forward Collision Warning is activated
later than normal. This setting reduces
the amount of distance between
the vehicle, pedestrian or cyclist (if
equipped) ahead before the initial
warning occurs.
Select ‘Late’ when traffic is light and
when driving speed is slow.
When you accelerate suddenly to the
vehicle ahead, the warning may seem
to activate earlier even if ‘Later’ is
selected.
Information
If you change the warning timing, the
warning timing of other systems may change.

Prerequisite for activation
FCA gets ready to be activated, when
‘Active Assist’ or ‘Warning Only’ under
Forward Safety is selected in the cluster
LCD display, and when the following
prerequisites are satisfied.
- ESC (Electronic Stability Control) is on.
- Vehicle speed is over 10 km/h (6 mph).
(FCA is only activated within a certain
speed range.)
- The system detects a pedestrian, cyclist or a vehicle in front, which may
collide with your vehicle. However,
FCA may not be activated or may only
sound a warning alarm depending on
the driving or vehicle conditions.
FCA may not operate properly according
to the frontal situation, condition of the
vehicle, the direction of pedestrian or
cyclist or speed. If you select "Warning
Only", only warnings occur.
WARNING
To avoid driver distractions, do not
attempt to set or cancel FCA while
driving the vehicle. Always completely
stop the vehicle at a safe place before
setting or canceling the system.
FCA automatically activates upon
placing the ignition switch to the ON
position. The driver can deactivate FCA
by canceling the system setting on the
cluster LCD display or infotainment
system display (if equipped).
FCA automatically deactivates upon
canceling ESC (Electronic Stability
Control). When ESC is canceled, FCA
cannot be activated in the LCD display
or infotainment system display (if
equipped). In this situation, the FCA
warning light will illuminate which is normal.
FCA Warning Message and Brake
Control
FCA 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, or the system detects
that a collision with a pedestrian or
cyclist is imminent.
Collision warning (First warning)
ODN8H069201L
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.
• If FCA detects a vehicle in front, the
system operates when your vehicle
speed is between 10 km/h (6 mph)
and 180 km/h (112 mph). Maximum
vehicle speed may decrease
depending on the condition of the
vehicle ahead and surroundings.
• If FCA detects a pedestrian or cyclist
in front, the system operates when
your vehicle speed is between 10
km/h (6 mph) and 85 km/h (53
mph). Maximum vehicle speed may
decrease depending on the condition
of the pedestrian or cyclist ahead and
surroundings.
• If you select ‘Warning Only’ for the
system setting, FCA system activates
and produces only warning alarms
in accordance with the collision risk
levels. You should control the brake
directly because FCA system will not
control the brake. Emergency braking (Second
warning)
ODN8H069202L
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. • FCA system limitedly controls the
brakes to preemptively mitigate
impact in a collision. The brake control
is maximized just before a collision.
• If FCA detects a vehicle in front, the
system operates when your vehicle
speed is above 10 km/h (6 mph) and
75 km/h (47 mph) or under. Maximum
vehicle speed may decrease
depending on the condition of the
vehicle ahead and surroundings.
• If FCA detects a pedestrian or cyclist
in front, the system operates when
your vehicle speed is between 10
km/h (6 mph) or above and under 65
km/h (40 mph). Maximum vehicle
speed may decrease depending on
the condition of the pedestrian or
cyclist ahead or surroundings.
• If you select ‘Warning Only’ for the
system setting, FCA system activates
and produces only warning alarms
in accordance with the collision risk
levels. You should control the brake
directly because FCA system will not
control the brake.

While Driving
6-54
Brake operation •
In an urgent situation, the braking
system enters into the ready status for
prompt reaction against the driver’s
depressing the brake pedal.
• FCA provides additional braking
power for optimum braking
performance, when the driver
depresses the brake pedal.
• The braking control is automatically
deactivated, when the driver sharply
depresses the accelerator pedal, or
when the driver abruptly operates the
steering wheel.
• FCA brake control is automatically
canceled, when risk factors disappear.
CAUTION
• The driver should always use
extreme caution while operating
the vehicle, whether or not there is a
warning message or alarm from FCA
system.
• After the brake control is activated,
the driver must immediately depress
the brake pedal and check the
surroundings. The brake activation
by the system lasts for about 2
seconds.
• If any other warning sound such as
seat belt warning chime is already
generated, Forward Collision-
Avoidance Assist system warning
may not sound.
• Playing the vehicle audio system at
high volume may prevent occupants
from hearing the system warning sounds.
WARNING
The braking control cannot completely
stop the vehicle nor avoid all
collisions. The driver should hold the
responsibility to safely drive and control
the vehicle.
WARNING
The FCA system logic operates within
certain parameters, such as the
distance from the vehicle, pedestrian or
cyclist (if equipped) ahead, the speed
of the vehicle ahead, and the driver’s
vehicle speed. Certain conditions
such as inclement weather and road
conditions may affect the operation of
FCA system.
WARNING
Never deliberately drive dangerously to
activate the system.
Information
Exceptional operation of the braking assist system • The vehicle drives on a slope or curve.
• The vehicle drives by a pedestrian or
cyclist at the crossroads, traffic signals
or structure.
• The vehicle drives through a tunnel or
near a railroad.

warning message will disappear once the
ESC warning light issue is resolved.
WARNING
• FCA is only a supplemental system
for the driver's convenience. The
driver should hold the responsibility
to control the vehicle operation. Do
not solely depend on FCA system.
Rather, maintain a safe braking
distance, and, if necessary, depress
the brake pedal to reduce the driving
speed or to stop the vehicle.
• In certain instances and under
certain driving conditions, FCA
system may activate unintentionally.
This initial warning message appears
on the LCD display with a warning chime.
Also due to sensing limitations, in
certain situations, the front radar
sensor or camera recognition
system may not detect the vehicle,
pedestrian or cyclist (if equipped)
ahead. FCA system may not activate
and the warning message may not be
displayed.
• Even if there is any problem with
the brake control function of FCA
system, the vehicle’s basic braking
performance will operate normally.
However, brake control function for
avoiding collision will not activate.
