Auto defogging system
(if equipped)
Auto defogging reduces the possibil-
ity of fogging up the inside of the
windscreen by automatically sensing
the moisture on inside the wind-
screen.
The auto defogging system operates
when the heater or air conditioning is
on.
Information
The auto defogging system may not
operate normally, when the outside
temperature is below -10 °C.When the Auto Defogging
System operates, the indi-
cator will illuminate.
If high level of moisture are sensed in
the vehicle, the Auto Defogging
System will operate in the following
order:
Step 1 : Outside air position
Step 2 :Operating the air conditioning
Step 3 : Blowing air toward the wind-
screen
Step 4 : Increasing air flow toward
the windscreen
If the air conditioning is off or recircu-
lated air position is manually selected
whilst Auto Defogging System is ON,
the Auto Defogging System Indicator
will blink 3 times to signal that the
manual operation has been can-
celled.To cancel or reset the Auto Defogging
System
Press the front windscreen defroster
button for 3 seconds when the igni-
tion switch is in the ON position.When the Auto Defogging System is
cancelled, the ADS OFF symbol will
blink 3 times and the ADS OFF will
be displayed on the climate control
information screen.
When the Auto Defogging System is
reset, the ADS OFF symbol will blink
6 times without a signal.
Information
• When the air conditioning is turned
on by Auto defogging system, if you
try to turn off the air conditioning, the
indicator will blink 3 times and the air
conditioning will not be turned off.
• For efficiency, do not select recircu-
lated air position whilst the Auto
defogging system is operating.
Do not remove the sensor cover
located on the upper end of the
windscreen glass.
Damage to system parts could
occur and may not be covered by
your vehicle warranty.

Driving your vehicle
FCA sensor
In order for the FCA system to oper-
ate properly, always make sure the
sensor cover or sensor is clean and
free of dirt, snow, and debris.
Never deliberately drive danger-
ously to activate the system.
WARNING
The FCA system logic operates
within certain parameters, such
as the distance from the vehi-
cle, pedestrian or cyclist (if
equipped) ahead, the speed of
the vehicle ahead, and the dri-
ver's vehicle speed. Certain
conditions such as inclement
weather and road conditions
may affect the operation of the
FCA system.
WARNING OAE058028
OAE058048
■ Front radar
■ Front camera
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
The driver should always use
extreme caution whilst oper-
ating the vehicle, whether or
not there is a warning mes-
sage or alarm from the 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,
the Forward Collision-
Avoidance Assist (FCA) sys-
tem warning may not sound.
Playing the vehicle audio sys-
tem at high volume may pre-
vent occupants from hearing
the system warning sounds.
CAUTION

5-59
Driving your vehicle

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 radar sensor.
Doing so may adversely affect
the sensing performance of the
radar.
Always keep the radar 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.
(Continued)(Continued)
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 FCA system may
not operate correctly. In this
case, a warning message may
not be displayed. We recom-
mend that you have the vehicle
inspected by an authorised
HYUNDAI dealer.
If the front bumper becomes
damaged in the area around the
radar sensor, the FCA system
may not operate properly. We
recommend that you have the
vehicle inspected by authorised
HYUNDAI dealer.
Use only genuine parts to repair
or replace a damaged sensor or
sensor cover. Do not apply paint
to the sensor cover. NEVER install any accessories
or stickers on the front wind-
screen, or tint the front wind-
screen.
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.
NEVER disassemble the camera
assembly, nor apply any impact
on the camera or assembly.
Information
We recommend that you have the sys-
tem checked by an authorised
HYUNDAI dealer when:
• The windscreen glass is replaced.
• The radar sensor or cover gets dam-
aged or replaced.

Warning message and warning
light
FCA disabled (Forward Collision
Avoidance Assist). Radar obscured
When the sensor cover is blocked
with dirt, snow, or debris, the FCA
system may not detect other vehi-
cles. If this occurs, a warning mes-
sage will appear on the LCD display.The system will operate normally
when such dirt, snow or debris is
removed.
FCA may not properly operate in an
area (e.g. open terrain), where any
substances are not detected after
turning ON the engine.
Also, even though a warning mes-
sage does not appear on the LCD
display, the FCA may not properly
operate.
System malfunction
Check FCA (Forward Collision -
Avoidance Assist warning) system
When FCA is not working properly,
the FCA warning light ( ) will illu-
minate and the warning message
will appear for a few seconds. After
the message disappears, the mas-
ter warning light ( ) will illumi-
nate. In this case, we recommend
that you have the vehicle inspected
by an authorised HYUNDAI dealer.
The FCA system may not acti-
vate according to the road con-
ditions, inclement weather, driv-
ing conditions or traffic condi-
tions.

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.
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 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.
(Continued)(Continued)
In certain instances and
under certain driving condi-
tions, the FCA system may
activate unintentionally. This
initial warning message
appears on the LCD display
with a warning chime.
Also due to sensing limita-
tions, in certain situations, the
front radar sensor or camera
recognition system may not
detect the vehicle, pedestrian
or cyclist (if equipped) ahead.
The FCA system may not acti-
vate and the warning mes-
sage may not be displayed.
Even if there is any problem
with the brake control func-
tion of the FCA system, the
vehicle's basic braking per-
formance will operate normal-
ly. However, brake control
function for avoiding collision
will not activate.
(Continued)
WARNING
(Continued)
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.
