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.

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 (Electr

onic Stability Control) is on.
- Vehicle speed is over 6 mph (10 km/h ).
(FCA is only activated within a certain
speed range.)
- The s

ystem 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.

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 6 mph (10 km/h )
and 112 mph (180 km/h). 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 6
mph (10 km/h ) and 53 mph (85
km/h). 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 6 mph (10 km/h ) and
47 mph (75 km/h) 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 6 mph
(10 km/h) or above and under 40 mph
(65 km/h). 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.

6-44
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.
