NEVER disassemble the sensor component or apply any impact
on the sensor component.
Be careful not to apply unneces- sary force on the radar sensor or
sensor cover. If the sensor is
forcibly moved out of proper
alignment, the system may not
operate correctly. In this case, a
warning message may not be
displayed. Have the vehicle
inspected by an authorized
HYUNDAI dealer.
Do not apply foreign objects such as a bumper sticker or a
bumper guard near the radar
sensor or apply paint to the sen-
sor area. Doing so may adverse-
ly affect the performance of the
sensor.
Warning message
Blind-Spot Collision Warning
(BCW) system disabled. Radar
blocked
This warning message may appear
when:
- One or both of the sensors on the rear bumper is blocked by dirt or
snow or a foreign object.
- Driving in rural areas where the sensor does not detect another
vehicle for an extended period of
time.
- When there is inclement weather such as heavy snow or rain. If any of these conditions occur, the
light on the BCW switch and the sys-
tem will turn off automatically.
When the BCW canceled warning
message is displayed in the cluster,
check to make sure that the rear
bumper is free from any dirt or snow
in the areas where the sensor is
located. Remove any dirt, snow, or
foreign material that could interfere
with the radar sensors.
After any dirt or debris is removed,
the system should operate normally
after about 10 minutes of driving the
vehicle.
If the system still does not operate
normally have your vehicle inspected
by an authorized HYUNDAI dealer.

The Forward Collision-Avoidance
Assist (FCA) system is designed to
help detect and monitor the vehicle
ahead or help detect a pedestrian in
the roadway through radar signals
and camera recognition to warn the
driver that a collision is imminent,
and if necessary, apply emergency
braking.
System Setting and Activation
System setting
Setting Forward Safety function The driver can activate the FCA by
placing the ignition switch to the
ON position and by selecting:
'User Settings → Driver Assistance
→ Forward Safety'
- If you select "Active Assist", the FCA system activates. The FCA
produces warning messages and
warning alarms in accordance
with the collision risk levels.
Braking assist will be applied in
accordance with the collision risk.
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 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 con-
ditions.
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.

ate properly, always make sure the
sensor cover or sensor is clean and
free of dirt, snow, and debris.Dirt, snow, or foreign substances on
the sensor cover or sensor may
adversely affect the sensing perform-
ance of the sensor.
Do not apply license plate frame
or foreign objects such as a
bumper sticker or a bumper
guard near the sensor. Doing so
may adversely affect the sens-
ing performance of the radar.
Always keep the sensor and cover clean and free of dirt and
debris.
Use only a soft cloth to wash the vehicle. Do not spray pressur-
ized water directly on the sensor
or sensor cover.
Be careful not to apply unneces- sary force on the sensor or sen-
sor cover. If the sensor is
forcibly moved out of proper
alignment, the FCA system may
not operate correctly. In this
case, a warning message may
not be displayed. Have the vehi-
cle inspected by an authorized
HYUNDAI dealer. If the front bumper becomes
damaged in the area around the
sensor, the FCA system may not
operate properly. Have the vehi-
cle inspected by an authorized
HYUNDAI dealer.
Use only genuine HYUNDAI parts to repair or replace a dam-
aged sensor or sensor cover. Do
not apply paint to the sensor
cover.
NEVER install any accessories or stickers on the front wind-
shield, or tint the front wind-
shield.
NEVER place any reflective objects (i.e. white paper, mirror)
over the crash pad. Any light
reflection may prevent the sys-
tem from functioning properly.
Pay extreme caution to keep the camera dry.

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).

The vehicle is on unpaved oruneven 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 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.)
The vehicle in front does not have rear lights or the rear lights are not
turned ON or the rear lights are
located unusually.
The outside brightness changes suddenly, for example when enter-
ing or exiting a tunnel The vehicle drives inside a build-
ing, such as a basement parking
lot
The adverse road conditions cause excessive vehicle vibrations while
driving
You are on a roundabout and the vehicle in front circles
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 camera is damaged.
The brightness outside is too low such as when the headlamps are
not on at night or the vehicle is
going through a tunnel.
Light coming from a street light or an oncoming vehicle is reflected on
a wet road surface such as a pud-
dle in the road
The field of view in front is obstructed by sun glare
The shadow is on the road by a median strip, trees, etc.
The vehicle drives through a toll- gate. The windshield glass is fogged up;
a clear view of the road is obstruct-
ed
The radar/camera sensor recogni- tion is limited
The rear part of the vehicle in front is not normally visible (for example,
the vehicle is spinning or the vehi-
cle is overturned)
There is severe irregular reflection from the radar sensor
The sensor recognition changes suddenly when passing over a
speed bump
The vehicle in front is driving errat- ically
The vehicle in front is moving verti- cally to the driving direction
The vehicle in front is stopped ver- tically
The vehicle in front is driving towards your vehicle or reversing

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.
