Warning and System Control
Rear Cross-Traffic Collision Warning (RCCW) system
If the vehicle detected by the sensors approaches from the rear left/right side
of your vehicle, the warning chime will sound, the warning light on the outer
side view mirror will blink and a warning will appear on the cluster LCD dis-
play. If the rear view monitor system is operating, a warning will also appear
on the AVN system screen.
The warning will stop when:
- the detected vehicle moves out of the sensing area or
- when the vehicle is right behind your vehicle or
- when the vehicle is not approaching your vehicle or
- when the other vehicle slows down.

Driving your vehicle
Rear Cross-Traffic Collision-Avoidance Assist (RCCA) system
If the risk of collision is detected while the RCCW is generated, brake control
may be activated. The instrument cluster will inform the driver of the brake
control. If the rear view monitor system is operating, a warning will also
appear on the AVN system screen.
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.
The driver must pay attention as the brake is disengaged after 2 seconds.
- The brake control by the system is canceled if the driver depresses the
brake pedal with sufficient power.
- Brake control is activated once for each right/left approach after shifting the
shift lever to R (Reverse).
The brake control may not operate properly according to the status of the
ESC (Electronic Stability Control). The same warning message is displayed
on the instrument cluster when:
- The ESC (Electronic Stability Control) warning light is on.
- The ESC (Electronic Stability Control) is engaged in a different function.

• Drive safely even though the
vehicle is equipped with a Rear
Cross-Traffic Collision Warning
system and Rear Cross-Traffic
Collision-Avoidance Assist
system. Do not solely rely on
the system but check your sur-
rounding 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 and Rear Cross-Traffic
Collision-Avoidance Assist
system may not operate prop-
erly or unnecessarily operate
depending on traffic and driv-
ing conditions.
• The Rear Cross-Traffic
Collision-Avoidance Assist
system is not a substitute for
safe driving practices, but a
convenience function only. It is
the responsibility of the driver
to always drive cautiously to
prevent unexpected and sud-
den situations from occurring.
Pay attention to the road condi-
tions at all times.
WARNING
• When the operation condition
of the Rear Cross-Traffic
Collision Warning system is
satisfied, the warning will
occur every time a vehicle
approaches the side or rear of
your stopped (0 mph (0 km/h)
vehicle speed) vehicle.
• The system's warning or brake
may not operate properly if the
left or right of your vehicle's
rear bumper is blocked by a
vehicle or obstacle.
• Always pay attention to road
and traffic conditions while
driving, whether or not the
warning light on the outer side
view mirror illuminates or
there is a warning alarm.
• Playing the vehicle audio sys-
tem at high volume may pre-
vent occupants from hearing
the system's warning sounds.
• 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.

Detecting Sensor
The rear radars are located inside
the rear bumper for detecting the
side and rear areas. Always keep the
rear bumper clean for proper opera-
tion of the system.
• The system may not work prop-
erly when the bumper has been
damaged, or if the rear bumper
has been replaced or repaired.
• The system may turn off if inter-
fered by electromagnetic waves.
• Always keep the sensors clean.
• 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
retailer of Genesis Branded
products.• 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/BCA switch and the
system 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 the vehicle inspected
by an authorized retailer of Genesis
Branded products.

may not detect the vehicle
approaching from behind and the
warning or brake may not operate
properly.
