Detecting sensor
The rear radars are the sensors
inside the rear bumper for detecting
the side and rear areas. Always keep
the rear bumper clean for proper
operation of the system.

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 in
accordance with your driving
situations.

Take the following precautions
when using the Forward
Collision- Avoidance Assist
(FCA) system:
This system is only a supple-
mental system and it is not
intended to, nor does it
replace the need for extreme
care and attention of the driv-
er. The sensing range and
objects detectable by the sen-
sors are limited. Pay attention
to the road conditions at all
times.
NEVER drive too fast in accor-
dance with the road condi-
tions or while cornering.
Always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. The Forward Collision-
Avoidance system may not
always stop the vehicle com-
pletely and is only intended to
help mitigate a collision that
is imminent.
WARNING
OTMA058186

5-74
Driving your vehicle- If you select "Warning Only", theFCA system activates and pro-
duces only warning alarms in
accordance with the collision risk
levels. You should control the
brake directly because the FCA
system do not control the brake.
- If you select "Off", the FCA sys- tem deactivates,
The warning light illu-
minates on the LCD
display, when you can-
cel the FCA system.
The driver can monitor the FCA
ON/OFF status on the LCD display.
Also, the warning light illuminates
when the ESC (Electronic Stability
Control) is turned off. If the warning
light remains ON when the FCA is
activated, have the system
checked by an authorized
HYUNDAI dealer. The driver can select the initial
warning activation time on the LCD
display.
Go to the 'User Settings → Driver
Assistance →Warning Timing →
Normal/Later'.
The options for the initial Forward
Collision Warning includes the fol-
lowing: - Normal :
When this condition is selected,
the initial Forward Collision
Warning is activated sensitively. If
you feel the warning activates too
early, set the 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.
- Later : When this condition is selected,
the initial Forward Collision
Warning is activated later than nor-
mal. This setting reduces the
amount of distance between the
vehicle ahead before the initial
warning occurs.
Select 'Later' when traffic is light
and when driving speed is slow.
Information
If you change the warning timing, the
warning time of other systems may
change. Always be aware before
changing the warning timing.

Prerequisite for activation
The FCA system is on and ready
when FCA is selected on the LCD
display and when the following pre-
requisites are satisfied:
- The ESC (Electronic StabilityControl) is on.
- Driving speed exceeds approxi- mately 6mph (10 km/h) (The FCA
is only activated within a certain
speed range.).
- The system detects a vehicle in front, which may collide with your
vehicle. (The FCA may not be acti-
vated or may sound a warning
alarm in accordance with the driv-
ing situation or vehicle condition.)
FCA Warning Message and
System Control
The FCA produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, insufficient braking dis-
tance detection. Also, it controls the
brakes in accordance with the colli-
sion risk levels.
The driver can select the initial warn-
ing activation time in the User
Settings in the LCD display. The
options for the initial Forward Collision
Warning include Early or Later initial
warning time.Completely stop the vehicle
on a safe location before
operating the switch on the
steering wheel to activate/
deactivate the FCA system.
The FCA automatically acti-
vates upon placing the igni-
tion switch to the ON position.
The driver can deactivate the
FCA by canceling the system
setting on the LCD display.
The FCA automatically deacti-
vates upon canceling the ESC
(Electronic Stability Control).
When the ESC is canceled,
the FCA cannot be activated
on the LCD display. The FCA
warning light will illuminate
which is normal.

levels. You should control the brake
directly because the FCA system
do not control the brake.
Brake operation
In an urgent situation, the brakingsystem enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
The FCA provides additional brak- ing 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.
The FCA braking control is auto- matically canceled, when risk fac-
tors disappear.
The driver should always use
extreme caution while operat-
ing the vehicle, whether or not
there is a warning message or
alarm from the FCA system.
If any other warning sound
such as seat belt warning
chime is already generated,
the Forward Collision-
Avoidance Assist (FCA) sys-
tem warning may not sound.
CAUTION
The FCA system logic operates
within certain parameters, such
as the distance from the vehicle
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 oper-
ation of the FCA system.
WARNING
The FCA 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

5-80
Driving your vehicle
The FCA is only a supplemen-
tal system for the driver’s con-
venience. The driver should
hold the responsibility to con-
trol 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.
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.
Also, in certain instances the
front camera recognition sys-
tem may not detect the vehi-
cle ahead. The FCA system
may not activate and the
warning message will not be
displayed.
WARNING 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 a colli-
sion.
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 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 vehi-
cle (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

- Driving on a curve
The performance of the FCA system
may be limited when driving on a
curved road.
In certain instances on a curved
road, the FCA system may activate
prematurely.
Also, in certain instances the front
camera recognition system may not
detect the vehicle traveling on a
curved road.
In these cases, the driver must main-
tain 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 driving
on a curved road.
In this case, the system may unnec-
essarily 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 distance.
Also, when necessary depress the
accelerator pedal to prevent the sys-
tem from unnecessarily decelerating
your vehicle.
- Driving on a slope
The performance of the FCA decreas-
es while driving upward or downward
on a slope, not recognizing the vehi-
cle in front in the same lane. It may
unnecessarily produce the warning
message and the warning alarm, or it
may not produce the warning mes-
sage and the warning alarm at all.
When the FCA suddenly recognizes
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.

Driving your vehicle
- Changing lanes
When a vehicle changes lanes in
front of you, the FCA system may not
immediately detect the vehicle, espe-
cially if the vehicle changes lanes
abruptly. In this case, you must main-
tain a safe braking distance, and if
necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance. When driving in stop-and-go traffic,
and a stopped vehicle in front of you
merges out of the lane, the FCA sys-
tem may not immediately detect the
new vehicle that is now in front of
you. In this case, you must maintain
a safe braking distance, and if nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.
- 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, addi-
tional special attention is required.
The FCA system 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 nec-
essary, depress the brake pedal to
reduce your driving speed in order to
maintain distance.
