• Forward Collision-Avoidance Assist
may activate during braking and the
vehicle may stop suddenly shifting
loose objects toward the passengers.
Always keep loose objects secured
and fasten the seat belt.
• Forward Collision-Avoidance Assist
may not activate if the driver applies
the brake pedal to avoid 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 Forward Collision-
Avoidance Assist. Pay extreme
caution.
• Forward Collision-Avoidance Assist
system operates only when the

Limitations of Forward Collision-
Avoidance Assist
Forward Collision avoidance assist is
designed to monitor the vehicle ahead
or a pedestrian or cyclist in the roadway
through radar signals and camera
recognition to warn the driver that a
collision is imminent, and if necessary,
apply emergency braking.
In certain situations, the radar sensor or
the camera may not be able to detect
the vehicle, pedestrian or cyclist ahead.
In these cases, Forward Collision-
Avoidance Assist may not operate
normally. The driver must pay careful
attention in the following situations
where Forward Collision-Avoidance
Assist operation may be limited.
Detecting vehicle, pedestrian and
cyclist
The sensor may be limited when:
• Forward Collision-Avoidance Assist
may not operate for 15 seconds after
the vehicle is started or the camera is
initialized
• The radar sensor or camera is covered
with a foreign object or debris
• The camera lens is contaminated 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 radar sensor or camera
• There is interference by
electromagnetic waves
• There is severe irregular reflection
from the radar sensor
• The radar/camera sensor recognition
is limited
• The vehicle in front is too small to be
detected (for example a motorcycle
etc.)
• The vehicle in front is an oversize
vehicle or trailer that is too big to be
detected by the camera recognition
function (for example a tractor trailer,
etc.)
• The camera’s field of view is not well
illuminated (either too dark or too
much reflection or too much backlight
that obscures the field of view)
• The vehicle in front does not have
their rear lights or their rear lights
does not turned ON or their rear lights
are located unusually

• Driving on a curved road
The performance of Forward Collision-
Avoidance Assist may be limited
when driving on a curved road.
The front view camera or radar sensor
recognition function 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 necessary,
depress the brake pedal to reduce
your driving speed in order to
maintain a safe distance.

While Driving

OADAS015SDOADAS015SD
Forward Collision-Avoidance Assist
may recognize a vehicle in the next
lane or outside the lane when driving
on a curved road.
If this occurs, Forward Collision-
Avoidance Assist may unnecessarily
alarm the driver and apply the brake.
Always pay attention to road and
driving conditions, while driving.
OADAS012SDOADAS012SD
• Driving on an inclined road
The performance of Forward Collision-
Avoidance Assist may be decreased
while driving upward or downward on
a slope.
The front view camera or front radar
sensor recognition may not detect the
vehicle in front.
This may result in unnecessary alarm
and braking or no alarm and braking
when necessary.
When Forward Collision-Avoidance
Assist suddenly recognizes the
vehicle in front while passing over
a slope, you may experience sharp
deceleration.

• 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 attention is required. Forward
Collision-Avoidance Assist may not
be able to detect the cargo extending
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.
Detecting pedestrians or cyclists
The sensor may be limited when:
• The pedestrian or cyclist is not fully
detected by the camera recognition
system, for example, if the pedestrian
is leaning over or is not fully walking
upright
• The pedestrian or cyclist is moving
very quickly or appears abruptly in the
camera detection area
• The pedestrian or cyclist is wearing
clothing that easily blends into the
background, making it difficult to be
detected by the camera recognition
system
• The outside lighting is too bright
(for example, when driving in bright
sunlight or in sun glare) or too dark
(for example, when driving on a dark
rural road at night)
• It is difficult to detect and distinguish
the pedestrian or cyclist from other
objects in the surroundings, for
example, when there is a group of
pedestrians, cyclists or a large crowd
• There is an item similar to a person’s
body structure
• The pedestrian or cyclist is small
• The pedestrian has impaired mobility
• The sensor recognition is limited
• The radar sensor or camera is blocked
with a foreign object or debris
• Inclement weather such as heavy rain
or snow obscures the field of view of
the radar sensor or camera
• When light coming from a street light
or an oncoming vehicle is reflected on
a wet road surface such as a puddle in
the road

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.Forward Collision-Avoidance Assist
may work when it recognizes objects
similar in shape or property to a vehicle,
pedestrian or cyclist.
Forward Collision-Avoidance Assist is
designed to help detect and monitor
the vehicle ahead or detect a pedestrian
or cyclist in the roadway through
radar signals and camera recognition.
It is not designed to detect bicycles,
motorcycles, or smaller wheeled
objects such as luggage bags, shopping
carts, or strollers.

While Driving
6-54
Junction Turning
Forward Collision-Avoidance Assist-
Junction Turning is designed to reduce
the risk of collision by detecting and
monitoring the oncoming vehicle ahead.
When the vehicle turns to the left at a
junction, Forward Collision-Avoidance
Assist recognises the oncoming vehicle
ahead in advance with the front view
camera and the front radar. It produces
warning messages or haptic warning
alarms in accordance with the collision
risk levels.
Prerequisite for activation
Forward Collision-Avoidance Assist is on
and ready if you select “Active Assist”
or “Warning Only” on the infotainment
system and when the following
prerequisites are satisfied:
-Forward Collision-Avoidance Assist
detects a oncoming vehicle in front,
which may collide with your vehicle.
It may be activated when the system
recognise the collision risk at a
junction in each situation.
-The ESC (Electronic Stability Control)
is on.
-The vehicle speed moving toward
your vehicle exceeds approximately 19
mph (30 km/h) or decreases under 44
mph (70 km/h).
-Driving speed exceeds approximately
6 mph (10 km/h) or decreases under
19 mph (30 km/h)
-Direction signals turn on.
CAUTION
• FCA system may not work or only
some part of the warning system may
perform according to the condition,
driving direction or speed of the
vehicle moving toward your vehicle.
• If you select “Warning only”, Forward
Collision-Avoidance Assist activates
and produces only warning alarms.
WARNING
• Forward Collision-Avoidance Assist
may not produce the warning alarm
or be activated too late due to the
unexpected driving caused by the
approaching vehicles.
• While turning left, only when the
turn signal is on along with the
driving direction, Forward Collision-
Avoidance Assist is activated toward
the approaching vehicles.
