• Driving on a curve
The performance of Forward
Collision-Avoidance Assist system
may be limited when driving on a
curved road.
The front view camera or front
radar sensor recognition system
may not detect the vehicle, pedes-
trian or cyclist traveling in front on
a curved road.
This may result in no alarm and
braking when necessary. Always
pay attention to road and driving
conditions, and if necessary,
depress the brake pedal to reduce
your driving speed in order to
maintain a safe distance.Forward Collision-Avoidance Assist
system may recognize a vehicle or
pedestrian or cyclist in the next lane
or outside the lane when driving on a
curved road.
If this occurs, the system may unnec-
essarily alarm the driver and apply
the brake.
Always pay attention to road and
driving conditions, while driving.

Driving your vehicle
• Driving on a slope
The performance of Forward
Collision-Avoidance Assist system
may be decreased while driving
upward or downward on a slope.
The front view camera or front
radar sensor recognition may not
detect the vehicle, pedestrian or
cyclist in front.
This may result in unnecessary
alarm and braking or no alarm and
braking when necessary.
When the system suddenly recog-
nizes the vehicle, pedestrian or
cyclist in front while passing over a
slope, you may experience sharp
deceleration. Always keep your
eyes forward while driving upward
or downward on a slope, and, if
necessary, depress the brake
pedal to reduce your driving speed
in order to maintain distance.• Changing lanes
When a vehicle changes lanes in
front of you, the FCA system may
not immediately detect the vehicle,
especially if the vehicle changes
lanes abruptly. In this case, you
must maintain a safe braking dis-
tance, and if necessary, depress
the brake pedal to reduce your
driving speed in order to maintain a
safe distance.
When driving in stop-and-go traffic,
and a vehicle in front of you
merges out of the lane, the FCA
system may not immediately
detect the new vehicle that is now
in front of you. In this case, you
must maintain a safe braking dis-
tance, and if necessary, depress
the brake pedal to reduce your
driving speed in order to maintain a
safe distance.

• Detecting the vehicle in front of you
If the vehicle in front of you has
cargo that extends rearward from
the cab, or when the vehicle in
front of you has higher ground
clearance, additional special atten-
tion is required. The FCA system
may not be able to detect the cargo
extending from the vehicle. In
these instances, you must maintain
a safe braking distance from the
rearmost object, and if necessary,
depress the brake pedal to reduce
your driving speed in order to
maintain distance.
Detecting pedestrians or
cyclists
The sensor may be limited when:
• The pedestrian or cyclist is not fully
detected by the camera recogni-
tion 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 wear-
ing 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 distin-
guish the pedestrian or cyclist from
other objects in the surroundings,
for example, when there is a group
of pedestrians, cyclist or a large
crowd
• There is an item similar to a per-
son's body structure
• The pedestrian is small
• The pedestrian has impaired mobil-
ity
• The sensor recognition is limited
• The radar sensor or camera is cov-
ered with a foreign object or debris
• 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

Driving your vehicle
Blind-Spot Collision-Avoidance
Assist (BCA) system
The Blind-Spot Collision-Avoidance
Assist system may apply braking
power, when an approaching vehicle
is detected within a certain distance
next to or behind your vehicle.
In this situation, the system gently
apply braking power on the tire,
which is located in the opposite side
of the possible-colliding point. The
instrument cluster will inform the
driver of the system activation.
Blind-Spot Collision-Avoidance Assist
system is automatically deactivated
when:
- The vehicle drives a certain dis-
tance away
- The vehicle direction is changed
against the possible-colliding point
- The steering wheel is abruptly
moved- The brake pedal is depressed
- After a certain period of time
The driver should drive the vehicle in
the middle of the vehicle lanes to
keep the system in the ready status.
When the vehicle drives too close to
one side of the vehicle lanes, the
system may not properly operate.
In addition, the system may not prop-
erly control your vehicle in accor-
dance with driving situations. Thus,
always pay close attention to road
conditions.

• The driver is responsible for
accurate steering.
• Do not unnecessarily operate
the steering wheel, when the
Blind-Spot Collision-Avoidance
Assist System is in operation.
• Always pay attention to road
and traffic conditions while
driving. The Blind-Spot
Collision-Avoidance Assist
system may not operate or
unnecessarily operate depend-
ing on certain situations.
• The Blind-Spot Collision-
Avoidance Assist system is not
a substitute for safe driving
practices, but is a supplemen-
tal system only. It is the respon-
sibility of the driver to always

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
