2023 HYUNDAI SONATA warning

While Driving
6-52
Prerequisite for activation
FCA gets ready to be activated, when
‘Active Assist’ or ‘Warning Only’ under
Forward Safety is selected in the cluster
LCD display, and when the following
prerequisites are satisfied.
- ESC (Electronic Stability Control) is on.
- Vehicle speed is over 10 km/h (6 mph).
(FCA is only activated within a certain
speed range.)
- The system detects a pedestrian, cyclist or a vehicle in front, which may
collide with your vehicle. However,
FCA may not be activated or may only
sound a warning alarm depending on
the driving or vehicle conditions.
FCA may not operate properly according
to the frontal situation, condition of the
vehicle, the direction of pedestrian or
cyclist or speed. If you select "Warning
Only", only warnings occur.
WARNING
To avoid driver distractions, do not
attempt to set or cancel FCA while
driving the vehicle. Always completely
stop the vehicle at a safe place before
setting or canceling the system.
FCA automatically activates upon
placing the ignition switch to the ON
position. The driver can deactivate FCA
by canceling the system setting on the
cluster LCD display or infotainment
system display (if equipped).
FCA automatically deactivates upon
canceling ESC (Electronic Stability
Control). When ESC is canceled, FCA
cannot be activated in the LCD display
or infotainment system display (if
equipped). In this situation, the FCA
warning light will illuminate which is normal.
FCA Warning Message and Brake
Control
FCA produces warning messages,
warning alarms, and emergency braking
based on the level of risk of a frontal
collision, such as when a vehicle ahead
suddenly brakes, or the system detects
that a collision with a pedestrian or
cyclist is imminent.
Collision warning (First warning)
ODN8H069201L
This warning message appears on the
LCD display with a warning chime.
Additionally, some vehicle system
intervention occurs by the engine
management system to help decelerate
the vehicle.

•
Your vehicle speed may decelerate
moderately.
• If FCA detects a vehicle in front, the
system operates when your vehicle
speed is between 10 km/h (6 mph)
and 180 km/h (112 mph). Maximum
vehicle speed may decrease
depending on the condition of the
vehicle ahead and surroundings.
• If FCA detects a pedestrian or cyclist
in front, the system operates when
your vehicle speed is between 10
km/h (6 mph) and 85 km/h (53
mph). Maximum vehicle speed may
decrease depending on the condition
of the pedestrian or cyclist ahead and
surroundings.
• If you select ‘Warning Only’ for the
system setting, FCA system activates
and produces only warning alarms
in accordance with the collision risk
levels. You should control the brake
directly because FCA system will not
control the brake. Emergency braking (Second
warning)
ODN8H069202L
This warning message appears on the
LCD display with a warning chime.
Additionally, some vehicle system
intervention occurs by the engine
management system to help decelerate
the vehicle. • FCA system limitedly controls the
brakes to preemptively mitigate
impact in a collision. The brake control
is maximized just before a collision.
• If FCA detects a vehicle in front, the
system operates when your vehicle
speed is above 10 km/h (6 mph) and
75 km/h (47 mph) or under. Maximum
vehicle speed may decrease
depending on the condition of the
vehicle ahead and surroundings.
• If FCA detects a pedestrian or cyclist
in front, the system operates when
your vehicle speed is between 10
km/h (6 mph) or above and under 65
km/h (40 mph). Maximum vehicle
speed may decrease depending on
the condition of the pedestrian or
cyclist ahead or surroundings.
• If you select ‘Warning Only’ for the
system setting, FCA system activates
and produces only warning alarms
in accordance with the collision risk
levels. You should control the brake
directly because FCA system will not
control the brake.

While Driving
6-54
Brake operation •
In an urgent situation, the braking
system enters into the ready status for
prompt reaction against the driver’s
depressing the brake pedal.
• FCA provides additional braking
power for optimum braking
performance, when the driver
depresses the brake pedal.
• The braking control is automatically
deactivated, when the driver sharply
depresses the accelerator pedal, or
when the driver abruptly operates the
steering wheel.
• FCA brake control is automatically
canceled, when risk factors disappear.
CAUTION
• The driver should always use
extreme caution while operating
the vehicle, whether or not there is a
warning message or alarm from FCA
system.
• After the brake control is activated,
the driver must immediately depress
the brake pedal and check the
surroundings. The brake activation
by the system lasts for about 2
seconds.
• If any other warning sound such as
seat belt warning chime is already
generated, Forward Collision-
Avoidance Assist system warning
may not sound.
• Playing the vehicle audio system at
high volume may prevent occupants
from hearing the system warning sounds.
WARNING
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 FCA system logic operates within
certain parameters, such as the
distance from the vehicle, pedestrian or
cyclist (if equipped) 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 operation of
FCA system.
WARNING
Never deliberately drive dangerously to
activate the system.
Information
Exceptional operation of the braking assist system • The vehicle drives on a slope or curve.
• The vehicle drives by a pedestrian or
cyclist at the crossroads, traffic signals
or structure.
• The vehicle drives through a tunnel or
near a railroad.
• The vehicle drives where steam, smoke
or shadow is on the road.
• The vehicle drives the road tree planted
or streetlamps installed.
• There is interference by
electromagnetic waves or electric noise.

When FCA is not working properly, FCA
warning light () will illuminate and the
warning message will appear for a few
seconds. After the message disappears,
the master warning light (
) will
illuminate. In this case, have the vehicle
inspected by an authorized HYUNDAI
dealer.
The FCA warning message may appear
along with the illumination of the ESC
(Electronic Stability Control) warning
light. Both FCA warning light and
warning message will disappear once the
ESC warning light issue is resolved.
WARNING
• FCA is only a supplemental system
for the driver's convenience. The
driver should hold the responsibility
to control the vehicle operation. Do
not solely depend on 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 conditions, FCA
system may activate unintentionally.
This initial warning message appears
on the LCD display with a warning chime.
Also due to sensing limitations, in
certain situations, the front radar
sensor or camera recognition
system may not detect the vehicle,
pedestrian or cyclist (if equipped)
ahead. FCA system may not activate
and the warning message may not be
displayed.
• Even if there is any problem with
the brake control function of FCA
system, the vehicle’s basic braking
performance will operate normally.
However, brake control function for
avoiding collision will not activate.

While Driving

•
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.
• FCA system 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.
• FCA system 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 FCA system. Pay extreme caution.
• FCA system operates only when the
system detect vehicles, pedestrian or
cyclist in front of the vehicle.
• FCA system may not activate
according to road conditions,
inclement weather, driving
conditions or traffic conditions.
• FCA system may not work for all
vehicles, passengers or cyclists.
WARNING
• FCA system does not operate when
the vehicle is in reverse.
• FCA system is not designed to detect
other objects on the road such as animals.
• FCA system does not detect vehicles
in the opposite lane.
• FCA system does not detect cross
traffic vehicles that are approaching.
• FCA system cannot detect vehicles
that are stopped vertically to your
vehicle at a intersection or dead end
street.
• FCA system cannot detect the cross
traffic cyclist that are approaching.
In these cases, you must maintain a
safe braking distance, and if necessary,
depress the brake pedal to reduce the
driving speed in order to maintain a
safe distance or to stop the vehicle.
Limitations of the System
Forward Collision avoidance assist
system 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, FCA system may
not operate normally. The driver must
pay careful attention in the following
situations where FCA operation may be
limited.

While Driving
6-64
•
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 (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 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

or an oncoming vehicle is reflected on
a wet road surface such as a puddle in
the road
• The field of view in front is obstructed
by sun glare
• The windshield glass is fogged up; a
clear view of the road is obstructed
• The adverse road conditions cause
excessive vehicle vibrations while driving
• The sensor recognition changes
suddenly when passing over a speed bump
• You are on a roundabout
