While Driving
6-50
Forward Collision-Avoidance Assist
system is designed to detect the
vehicle, a pedestrian or cyclist ahead (if
equipped) in the roadway through front
radar signals and front view camera
recognition to warn the driver that a
collision is imminent, and if necessary,
apply emergency braking.
WARNING
Take the following precautions when
using Forward Collision-Avoidance
Assist system: • This system is only a supplemental
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 conditions.
• Always drive cautiously to prevent
unexpected and sudden situations
from occurring. FCA does not always
stop the vehicle completely.
System Setting and Activation
System setting
OTMA058186
• Setting Forward Safety function
The driver can activate FCA by placing
the ignition switch to the ON position
and by selecting:

Forward Safety’
- If you select ‘Active Assist’, FCA system activates. 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.
- If you select ‘Warning Only’, FCA system activates and produces only
warning alarms in accordance with
the collision risk levels. Braking
assist will not be applied in this
setting.
- If you select ‘Off’, FCA system deactivates. If you turn the ESC off
stage 2, FCA deactivates and the
warning light comes on.

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 pressurized
water directly on the sensor or
sensor cover.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly moved
out of proper alignment, FCA system
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• If the front bumper becomes
damaged in the area around the
radar sensor, FCA system may not
operate properly. Have the vehicle
inspected by an authorized HYUNDAI

Check Forward Collision Avoidance Assist system
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.
