Safety system of your vehicle
In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags.
Just before impact, drivers often
brake heavily. Such heavy braking
lowers the front portion of the vehicle
causing it to "ride" under a vehicle
with a higher ground clearance. Air
bags may not inflate in this "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
"underride" collisions.Front air bags may not inflate in
rollover accidents because air bag
deployment could not provide protec-
tion to the occupants.
However, side and curtain air bags
may inflate when the vehicle is rolled
over by a side impact collision.
Information
Front air bags do not inflate in
rollover accidents. However, side
impact and curtain air bags may
inflate in a rollover, when it is detect-
ed by the rollover sensor.

5. Driving Your Vehicle

When certain conditions are met, the
engine is automatically decoupled
from the transmission while the shift
lever is remained in D (Drive). In this
Coasting mode, the engine stays at
idling speed to reduce fuel consump-
tion and increase coasting distance.
Coasting Setting
The Coasting function must be
turned ON from the Settings menu in
the AVN system screen. Select:
- Setup →Vehicle Settings →Drive
Mode →Coasting
For detailed information, scan the
QR code in a separately supplied
simple manual.
When Coasting is turned ON and the
conditions are met, the function
operates with a "Coasting" message
illuminated at the top center of the
instrument cluster.
• If the accelerator pedal is
pressed quickly for accelerating
with the Coasting function in
operation, acceleration may
occur after the engagement of
the clutch inside the transmis-
sion. In turn, the driver may con-
tinue to feel acceleration even
after the system is turned off.
• Driving with the Coasting func-
tion off may be required in some
cases since the engine brake is
not applied while the Coasting
function is in operation.
• Operating the AVN system
screen to activate or deactivate
the Coasting function while driv-
ing may be dangerous as the dri-
ver's attention is dispersed.
Coasting Operating
Conditions
The Coasting function will operate
when the accelerator pedal is
depressed and released under the
following conditions.
• The driving mode is ECO mode.
• SMART is selected for Engine/
Transmission in CUSTOM mode
from the AVN system screen and
driver acceleration is SMART ECO
• ECO is selected for Engine/
Transmission in CUSTOM mode
from the AVN system screen
• The shift lever is in D (Drive)
• The Smart Cruise Control button is
OFF
• The accelerator or brake pedal is
not depressed
• The vehicle's speed is within
35–100 mph (55–160 km/h) range
• The road gradient is within -5~+5%
range
• In SMART mode, if the distance
between the vehicle ahead and the
relative speed is within a certain
range
Information
• If the front radar for smart cruise
control system cannot operate nor-
mally, the inter-vehicle distance and
relative speed condition are auto-
matically ignored.
• The Coasting function works after
the engine is turned on, the trans-
mission is warmed up, and the
engine sensor self-diagnosis is com-
pleted after starting.
• Depending on the driving situation,
Coasting operation may be tem-
porarily delayed even if the above
conditions are met.

System Malfunction
Check Forward Collision-
Avoidance Assist 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, have the vehicle
inspected by an authorized retailer
of Genesis Branded products.
• 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.
OHI048200L
• FCA is only a supplemental
system for the driver's con-
venience. It is the driver's
responsibility to control 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.
WARNING
• In certain instances and
under certain driving condi-
tions, the FCA system may
produce a warning alarm and
control the brake system
unnecessarily. And, the FCA
system may not produce a
warning alarm and control the
brake system due to detecting
limitation of sensor.
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 ahead. The FCA sys-
tem may not activate and the
warning message 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.
• 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.

Limitations of the System
The 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, the
FCA system may not operate nor-
mally. The driver must pay careful
attention in the following situations
where the FCA operation may be
limited.
Detecting vehicles
The sensor may be limited when:
• The system may not operate for 15
seconds after the engine is started
or the camera is initialized
• 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
• Inclement weather such as heavy
rain or snow obscures the field of
view of the radar sensor or camera
• There is interference by electro-
magnetic waves
• There is severe irregular reflection
from the radar sensor
• The radar/camera sensor recogni-
tion is limited
• The vehicle in front is too small to
be detected (for example a motor-
cycle or a bicycle, etc.) • The FCA system does not
operate when the vehicle is in
reverse.
• The FCA system is not
designed to detect other
objects on the road such as
animals.
• The FCA system does not
detect vehicles in the oppo-
site lane.
• The FCA system does not
detect cross traffic vehicles
that are approaching.
• The FCA system cannot
detect cross traffic cyclists
that are approaching.
• The FCA system cannot
detect vehicles that are
stopped vertically to your
vehicle at a intersection or
dead end street.
In these cases, you must main-
tain a safe braking distance,
and if necessary, depress the
brake pedal to reduce the driv-
ing speed in order to maintain a
safe distance or to stop the
vehicle.
WARNING
• The brake control may not
work, possibly causing a colli-
sion, 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.
• The FCA system operates
only when the system detect
vehicles, pedestrian or cyclist
in front of the vehicle.

• 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.
OHI058305LOHI058306L

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
