Collision Warning
(First warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs to help
decelerate the vehicle. If FCA detects a vehicle in front,
the system operates when your
vehicle speed is between 5 mph (8
km/h) and 40 mph (65 km/h).
Maximum vehicle speed may
decrease depending on the condi-
tion of the vehicle ahead and sur-
roundings.
If FCA detects a pedestrian in
front, the system operates when
your vehicle speed is between 5
mph (8 km/h) and 40 mph (65
km/h). Maximum vehicle speed
may decrease depending on the
condition of the pedestrian and
surroundings.
If you select 'Warning only' for the
system setting, FCA system acti-
vates and produces only warning
alarms in accordance with the col-
lision risk levels. You should control
the brake directly because FCA
system will not control the brake.
Emergency braking
(Second warning)
This warning message appears on
the LCD display with a warning
chime. Additionally, some vehicle
system intervention occurs to help
decelerate the engine.
If FCA detects a vehicle in front,
the system operates when your
vehicle speed is above 5 mph (8
km/h) and less than or equal to 110
mph (180 km/h). Maximum vehicle
speed may decrease depending
on the condition of the vehicle
ahead and surroundings.

Driving your vehicle
If you select 'Warning only' for the
system setting, FCA system acti-
vates and produces only warning
alarms in accordance with the col-
lision risk levels. You should control
the brake directly because FCA
system will not control the brake.
Brake operation
In an urgent situation, the braking
system enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
FCA provides additional braking
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 accelerator
pedal, or when the driver abruptly
operates the steering wheel.
FCA brake control is automatically
canceled, when risk factors disap-
pear.
5
The driver should always use
extreme caution while operat-
ing the vehicle, whether or not
there is a warning message or
alarm from FCA system.
After the brake control is acti-
vated, the driver must immedi-
ately depress the brake pedal
and check the surroundings.
The brake activation by the
system lasts for about 2 sec-
onds.
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 sys-
tem at high volume may pre-
vent occupants from hearing
the system warning sounds.
CAUTION
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
Never deliberately drive danger-
ously to activate the system.
WARNING
FCA system logic operates
within certain parameters, such
as the distance from the vehi-
cle, ahead, the speed of the
vehicle ahead, and the driver's
vehicle speed. Certain condi-
tions such as inclement weath-
er and road conditions may
affect the operation of FCA sys-
tem.
WARNING

5-54
The FCA warning message may
appear along with the illumination
of the ESC (Electronic Stability
Control) warning light. Both FCA
warning light and warning mes-
sage will disappear once the ESC
warning light issue is resolved.
Driving your vehicle
FCA is only a supplemental
system for the driver's con-
venience. The driver should
hold the responsibility to con-
trol 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.
In certain instances and
under certain driving condi-
tions, FCA system may unin-
tentionally activate. This initial
warning message appears on
the LCD display with a warn-
ing chime.

WARNING
(Continued)
Also, in certain instances the
front camera recognition sys-
tem may not detect the vehi-
cle ahead. FCA system may
not activate and the warning
message will not be dis-
played.
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 acti-
vate.
If the vehicle in front stops
suddenly, you may have less
control of the brake system.
Therefore, always keep a safe
distance between your vehicle
and the vehicle in front of you.
FCA system may activate dur-
ing braking and the vehicle
may stop suddenly shifting
loose objects toward the pas-
sengers. Always keep loose
objects secured.
(Continued)
(Continued)
FCA system may not activate
if the driver applies the brake
pedal to avoid a collision.
The brake control may be
insufficient, possibly causing
a collision, if a vehicle in front
abruptly stops. Always pay
extreme caution.
Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
FCA system operates only to
help detect vehicles in front of
the vehicle.

Limitations of the System
Forward Collision-Avoidance Assist
system is designed to help monitor
the vehicle ahead in the roadway
through camera recognition to warn
the driver that a collision is imminent,
and if necessary, apply emergency
braking.
In certain situations, the camera may
not be able to detect the vehicle
ahead. In these cases, FCA system
may not operate normally. The driver
must pay careful attention in the fol-
lowing situations where FCA opera-
tion may be limited.
Detecting vehicles
The sensor may be limited when:
The front view camera is blocked
with a foreign object or debris
The front view camera lens is con-
taminated due to tinted, filmed or
coated windshield, damaged
glass, or stuck of foreign matter
(sticker, bug, etc.) on the glass
Inclement weather such as heavy
rain or snow obscures the field of
view of the camera
The vehicle is on unpaved or
uneven rough surfaces, or road
with sudden gradient changes.
The camera sensor recognition is
limited
The vehicle in front is too small to
be detected (for example a motor-
cycle or a bicycle, etc.)
The front view camera does not
recognize the entire vehicle in
front.
The vehicle in front is an oversize
vehicle or trailer that is too big to
be detected by the camera recog-
nition system (for example a tractor
trailer, etc.)
5
FCA system does not operate
when the vehicle is in reverse.
FCA system is not designed
to detect other objects on the
road such as animals.
FCA system does not detect
vehicles in the opposite lane.
FCA system does not detect
cross traffic vehicles that are
approaching.
FCA system cannot detect the
driver approaching the side
view of a parked vehicle (for
example on a dead end
street.)
In these cases, you must main-
tain a safe braking distance,
and if necessary, depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance.
WARNING

5-57
Driving your vehicle
It is difficult to detect and distin-
guish the pedestrian from other
objects in the surroundings, for
example, when there is a group of
pedestrians or a large crowd.
There is an item similar to a per-
son's body structure.
The pedestrian is small.
The pedestrian has impaired
mobility.
When the pedestrian suddenly
interrupts in front of the vehicle
Driving on a curve
The performance of Forward
Collision-Avoidance Assist system
may be limited when driving on a
curved road.
The front camera recognition sys-
tem may not detect the vehicle
traveling in front on a curved road.
This may result in no alarm and
braking when necessary.
Always pay attention to road and
driving conditions, and if neces-
sary, depress the brake pedal to
reduce your driving speed in order
to maintain a safe distance.Forward Collision-Avoidance Assist
system may recognize a vehicle in
the next lane or outside the lane
when driving on a curved road.
If this occurs, the system may unnec-
essarily alarm the driver and apply
the brake. Always pay attention to
road and driving conditions, while
driving.

Driving on a slope
The performance of Forward
Collision-Avoidance Assist system
may be decreased while driving
upward or downward on a slope.
The front camera recognition may
not detect the vehicle in front. This
may result in unnecessary alarm
and braking or no alarm and brak-
ing when necessary.
When the system suddenly recog-
nizes 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 to reduce
your driving speed in order to
maintain distance.
Changing lanes
When a vehicle changes lanes in
front of you, Forward Collision-
Avoidance Assist system may not
immediately detect the vehicle,
especially if the vehicle changes
lanes abruptly. In this case, you
must maintain a safe braking dis-
tance, and if necessary, depress
the brake pedal to reduce your
driving speed in order to maintain a
safe distance.

Driving your vehicle
When driving in stop-and-go traffic,
and a vehicle in front of you merges
out of the lane, Forward Collision-
Avoidance Assist system may not
immediately detect the new vehicle
that is now in front of you. In this case,
you must maintain a safe braking dis-
tance, and if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain a safe dis-
tance. Detecting the vehicle in front of you
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, additional special atten-
tion is required. Forward Collision-
Avoidance Assist system may not
be able to detect the cargo extend-
ing from the vehicle. In these
instances, you must maintain a
safe braking distance from the
rearmost object, and if necessary,
depress the brake pedal to reduce
your driving speed in order to
maintain distance.

Do not use Forward Collision-
Avoidance Assist system
when towing a vehicle.
Application of the FCA sys-
tem while towing may
adversely affect the safety of
your vehicle or the towing
vehicle.
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.
FCA system is designed to
help detect and monitor the
vehicle ahead in the roadway
through camera recognition. It
is not designed to detect bicy-
cles, motorcycles, or smaller
wheeled objects such as lug-
gage bags, shopping carts, or
strollers.
Never try to test the operation
of FCA system. Doing so may
cause severe injury or death.

Prerequisite for activation
FCA gets ready to be activated,
when 'Active Assist' or 'Warning
Only' under Forward Safety is select-
ed in the cluster LCD display, and
when the following prerequisites are
satisfied.
- ESC (Electronic Stability Control)
is on.
- Vehicle speed is over 5 mph (8
km/h). (FCA is only activated with-
in a certain speed range.)
- The system detects a pedestrian,
cyclist (if equipped) 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,
the direction of pedestrian or
cyclist (if equipped) and speed.
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 (if
equipped) is imminent.To avoid driver distractions,
do not attempt to set or can-
cel FCA while driving the vehi-
cle. Always completely stop
the vehicle at a safe place
before setting or canceling
the system.
FCA automatically activates
upon placing the Engine
start/stop button to the ON
position. The driver can deacti-
vate FCA by canceling the sys-
tem setting on the cluster LCD
display.
FCA automatically deactivates
upon canceling the ESC
(Electronic Stability Control).
When the ESC is canceled,
FCA cannot be activated on
the LCD display. In this situa-
tion, the FCA warning light will
illuminate which is normal.
