different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all four
tires and wheels are the same
size. Never drive the vehicle with
different sized wheels and tires

backwards when starting a vehicle
from a stop on a hill. The system
operates the brakes automatically for
approximately 2 seconds and releas-
es the brake after 2 seconds or when
the accelerator pedal is depressed.
Information
• The HAC does not operate when the
gear is in P (Park) or N (Neutral).
• The HAC activates even when the
ESC (Electronic Stability Control) is
off. However, it does not activate,
when the ESC does not operate nor-
mally.

Driving your vehicle
If FCA detects a vehicle in front,
the system operates when your
vehicle speed is above 5 mph (8
km/h) and less than or equal to 110
mph (180 km/h). 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 5 mph (8 km/h) or above
and under 45 mph (70 km/h).
Maximum vehicle speed may
decrease depending on the condi-
tion of the pedestrian or cyclist
ahead and surroundings.
If you select 'Warning Only' for the
system setting, FCA system acti-
vates and produces only warning
alarms in accordance with the col-
lision risk levels. You should control
the brake directly because FCA
system will not control the brake.
Brake operation
In an urgent situation, the braking
system enters into the ready status
for prompt reaction against the dri-
ver's depressing the brake pedal.
FCA provides additional braking
power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical-
ly deactivated, when the driver
sharply depresses the accelerator
pedal, or when the driver abruptly
operates the steering wheel.
The FCA brake control is automat-
ically canceled, when risk factors
disappear.The driver should always use
extreme caution while operat-
ing the vehicle, whether or not
there is a warning message or
alarm from FCA system.
After the brake control is acti-
vated, the driver must immedi-
ately depress the brake pedal
and check the surroundings.
The brake activation by the
system lasts for about 2 sec-
onds.
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 sys-
tem at high volume may pre-
vent occupants from hearing
the system warning sounds.CAUTION

Driving your vehicle
There is an item similar to a per-
son's body structure
The pedestrian or cyclist is small
The pedestrian has impaired
mobility
The sensor recognition is limited
The front radar sensor or front view
camera is blocked with a foreign
object or debris
Inclement weather such as heavy
rain or snow obscures the field of
view of the front radar sensor or
front view camera
When light coming from a street
light 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 obstruct-
ed
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
The pedestrian or cyclist suddenly
interrupts in front of the vehicle
The cyclist in front is riding inter-
sected with the driving direction
There is any other electromagnetic
interference
The construction area, rail or other
metal object is near the cyclist
The bicycle material is not reflected
well on the front radar
In case of camera or radar sensor
recognition is in a marginal state.Use extreme caution when 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.
Forward Collision-Avoidance
Assist system may operate
when an object, which has
similar shape or characteris-
tic to a vehicle, pedestrian or
cyclist, is detected.
FCA system is designed to
detect and monitor the vehicle
ahead or detect a pedestrian
or cyclist (if equipped) in the
roadway through radar sig-
nals and camera recognition.
It is not designed to detect
bicycles, motorcycles, or
smaller wheeled objects such
as luggage bags, shopping
carts, or strollers.

Driving your vehicle
Lane Keeping Assist system helps
detect lane markers on the road with
a front view camera at the front
windshield, and assists the driver's
steering to help keep the vehicle
between lanes.
When the system detects the vehicle
straying from its lane, it alerts the
driver with a visual and audible warn-
ing, while applying a slight counter-
steering torque, trying to help pre-
vent the vehicle from moving out of
its lane.

Lane Keeping Assist system is
not a substitute for safe driving
practices, but a convenience
function only. It is the responsi-
bility of the driver to always be
aware of the surroundings and
steer the vehicle.
WARNING
Take the following precautions
when using Lane Keeping
Assist system :
Do not turn the steering wheel
suddenly when the steering
wheel is being assisted by the
system.
LKA system helps to prevent
the driver from moving out of
the lane unintentionally by
assisting the driver's steering.
However, the driver should
not solely rely on the system
but always pay attention on
the steering wheel to stay in
the lane.
The operation of LKA system
can be cancelled or not work
properly according to road
condition and surroundings.
Always be cautious when
driving.

(Continued)
The system detects lane
markers and controls the
steering wheel by a front view
camera, therefore, if the lane
markers are hard to detect,
the system may not work
properly.
Please refer to "Limitations of
the System".
Do not remove or damage the
related parts of LKA system.
You may not hear a warning
sound of LKA system if the
audio volume is high.
Do not place objects on the
dashboard that reflects light
such as mirrors, white paper,
etc. This may prevent LKA
system from functioning
properly.
When the lane markers are
hard to detect, please refer to
"Driver's Attention".
(Continued)(Continued)
Always have your hands on
the steering wheel while LKA
system is activated. If you
continue to drive with your
hands off the steering wheel
after the "Keep hands on
steering wheel" warning mes-
sage appears, the system will
stop controlling the steering
wheel.
The steering wheel is not con-
tinuously controlled so if the
vehicle speed is at a higher
rate when leaving a lane the
vehicle may not be controlled
by the system. The driver
must always follow the speed
limit when using the system.
If you attach objects to the
steering wheel, the system
may not assist steering or the
hands off alarm may not work
properly.
When you tow a trailer, make
sure that you turn off LKA
system.(Continued)
Do not disassemble LKA sys-
tem camera temporarily to
tint the window or attach any
types of coatings and acces-
sories. If you disassemble the
camera and assemble it again,
we recommend that you take
your vehicle to an authorized
HYUNDAI dealer and have the
system checked for calibra-
tion.
When you replace the wind-
shield glass, LKA system
camera or related parts of the
steering wheel, we recom-
mend that you take your vehi-
cle to an authorized HYUNDAI
dealer and have the system
checked for calibration.
