Safety system of your vehicle
In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags. Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehicle
causing it to "ride" under a vehicle
with a higher ground clearance. Air
bags may not inflate in this "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
"underride" collisions.Front air bags may not inflate in
rollover accidents because air bag
deployment could not provide protec-
tion to the occupants.
However, side and curtain air bags
may inflate when the vehicle is rolled
over by a side impact collision.

Detecting sensor
The rear radars are located inside
the rear bumper for detecting the
side and rear areas. Always keep the
rear bumper clean for proper opera-
tion of the system.
The system may not work prop-erly when the bumper has been
damaged, or if the rear bumper
has been replaced or repaired.
The system may turn off if inter- fered by electromagnetic waves.
Always keep the sensors clean.
NOTICE
The Rear Cross-Traffic
Collision Warning system is
not a substitute for safe driv-
ing practices, but a conven-
ience function only. It is the
responsibility of the driver to
always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. Pay attention to the road
conditions at all times.If any other warning sound
such as seat belt warning
chime is already generated,
the Rear Cross-Traffic
Collision Warning system
warning may not sound.
Drive safely even though the
vehicle is equipped with a
Rear Cross-Traffic Collision
Warning system. Do not sole-
ly rely on the system but
check your surrounding when
backing the vehicle up.
The driver is responsible for
accurate brake control.
Always pay extreme caution
while driving. The Rear Cross-
Traffic Collision Warning sys-
tem may not operate properly
or unnecessarily operate
depending on traffic and driv-
ing conditions.

Limitations of the System
The Forward Collision Avoidance
Assist (FCA) system is designed to
monitor the vehicle ahead on 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, the FCA sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
FCA operation may be limited.
Detecting vehicles
The sensor may be limited when:
The camera is blocked with a for-eign object or debris
Inclement weather such as heavy rain or snow obscures the field of
view of the camera
There is interference by electro- magnetic waves
The vehicle is on unpaved or uneven rough surfaces, or road
with sudden gradient changes.
The vehicle drives through a con- struction area, on an unpaved
road, or above metal materials,
such as a railway
The vehicle in front is too small to be detected (for example a motor-
cycle or a bicycle, 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 camera does not recognize the entire vehicle in front.
The FCA system operates
only to detect vehicles in front
of the vehicle.
The FCA system does not
operate when the vehicle is in
reverse.
The FCA system is not
designed to detect other
objects on the road such as
animals.
The FCA system does not
detect vehicles in the oppo-
site lane.
The FCA system does not
detect cross traffic vehicles
that are approaching.
The 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 or to stop the
vehicle.
WARNING

Both FCA warning light and warn-
ing message will disappear once
the ESC warning light issue is
resolved.
FCA is only a supplemental
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 to stop the vehicle.
In certain instances and
under certain driving condi-
tions, the FCA system may
activate prematurely. This ini-
tial warning message appears
on the LCD display with a
warning chime.
WARNING
Also due to sensing limita-
tions, in certain situations, the
front radar sensor or camera
recognition system may not
detect the vehicle or pedestri-
an ahead. The FCA system
may not activate and the
warning message may not be
displayed.
If there is a malfunction with
the FCA system, the Forward
Collision avoidance assist
system is not applied even
though the braking system is
operating normally.
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.
The FCA system may activate
during braking and the vehi-
cle may stop suddenly shift-
ing loose objects toward the
passengers. Always keep
loose objects secured.
The FCA system may not acti-
vate 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.
The FCA system may not acti-
vate according to the road
conditions, inclement weath-
er, driving conditions or traffic
conditions.
Occupants may get injured, if
the vehicle abruptly stops by
the activated FCA system. Pay
extreme caution.
The FCA system does not
detect all vehicles.

Limitations of the System
The Forward Collision Avoidance
Assist (FCA) system is designed to
monitor the vehicle ahead or a
pedestrian on the roadway through
radar signals and camera recogni-
tion to warn the driver that a collision
is imminent, and if necessary, apply
emergency braking.
In certain situations, the radar sen-
sor or the camera may not be able to
detect the vehicle or pedestrian
ahead. In these cases, the FCA sys-
tem may not operate normally. The
driver must pay careful attention in
the following situations where the
FCA operation may be limited.
Detecting vehicles
The sensor may be limited when:
The radar sensor or camera isblocked 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
There is interference by electro- magnetic waves
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 or to stop the
vehicle.
The FCA system operates
only to detect vehicles or
pedestrians in front of the
vehicle.
The FCA system does not
operate when the vehicle is in
reverse.
The FCA system is not
designed to detect other
objects on the road such as
animals.
The FCA system does not
detect vehicles in the oppo-
site lane.
The FCA system does not
detect cross traffic vehicles
that are approaching.
The FCA system cannot
detect the driver approaching
the side view of a parked vehi-
cle (for example on a dead
end street).
WARNING

5-96
Driving your vehicle
Driving on a curve The performance of the FCA sys-
tem may be limited when driving
on a curved road.
This may cause the alarm or brak-
ing to activate or not activate
improperly.
Also, in certain instances the front
radar sensor or camera recognition
system may not detect the vehicle
traveling on a curved road.
In these cases, the driver must
maintain a safe braking distance,
and if necessary, depress the
brake pedal to reduce your driving
speed in order to maintain a safe
distance. The FCA system may recognize a
vehicle in the next lane when driv-
ing on a curved road.
In this case, the system may
unnecessarily alarm the driver and
apply the brake.
Always pay attention to road and
driving conditions, while driving. If
necessary, depress the brake
pedal to reduce your driving speed
in order to maintain a safe dis-
tance.
Also, when necessary depress the
accelerator pedal to prevent the
system from unnecessarily decel-
erating your vehicle.
Check the road conditions for safe
operation of the FCA system. Driving on a slope
The performance of the FCA
decreases while driving upward or
downward on a slope, not recog-
nizing the vehicle in front in the
same lane. It may unnecessarily
produce the warning message and
the warning alarm, or it may not
produce the warning message and
the warning alarm at all.
When the FCA suddenly recog-
nizes the vehicle in front while
passing over a slope, you may
experience sharp deceleration.

Driving your vehicle
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. The FCA system
may not be able to detect the cargo
extending from the vehicle. In
these instances, you must main-
tain a safe braking distance from
the rearmost object, and if neces-
sary, depress the brake pedal to
reduce your driving speed in order
to maintain distance.
Detecting pedestrians
The sensor may be limited when:
The pedestrian is not fully detectedby the camera recognition system,
for example, if the pedestrian is
leaning over or is not fully walking
upright
The pedestrian is moving very quickly or appears abruptly in the
camera detection area
The pedestrian is wearing clothing that easily blends into the back-
ground, making it difficult to be
detected by the camera recogni-
tion system
If the bicycle material is not reflect- ed well on the radar
When the pedestrian or cyclist suddenly interrupts in front of the
vehicle
When there is any other electro- magnetic interference
The outside lighting is too bright (e.g. when driving in bright sunlight
or in sun glare) or too dark (e.g.
when driving on a dark rural road
at night) 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
The sensor recognition is limited
The radar sensor or camera is blocked 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
The brightness outside is too low such as when the headlamps are
not on at night or the vehicle is
going through a tunnel
Inclement weather such as heavy rain or snow obscures the field of
view of the radar sensor or camera
