Driving your vehicle
Operating conditions
The system is activated when the
Lane Following Assist is selected
from the vehicle Settings mode when
the following conditions are satisfied:
- The Smart Cruise Control is in acti-
vation (vehicle deceleration and
acceleration)
- Vehicle speed is lower than 90
mph (145 km/h)
When the system is activated, the
indicator ( ) on the cluster will illu-
minate. The color of the indicator will
change depending on the condition
of LFA system.
- Green : The system is in the assist
state.
- White : The system is in the ready
state.
LFA activation
After LFA is activated, if the vehicle
is within the lane and both lane
markers are detected (lane color
changes grey to white) and there is
no abrupt steering by the driver,
indicator light will change from
white to green. This indicates that
the LFA system is in the ASSIST
state and the steering wheel will be
able to be controlled. When the system does not recog-
nize the lane or depending on the
vehicle condition in front (presence
of the vehicle, driving status, etc.).
the steering wheel is controlled
restrictively.
When the control of the steering
wheel is stopped temporarily the
activation indicator blinks in green
and then changes to white.5

Driving your vehicleInformation
• Even though the steering is assisted
by the system, the driver may con-
trol the steering wheel.
• The steering wheel may feel heavier
when the steering wheel is assisted
by the system than when it is not.
Check LFA (Lane Following Assist)
system
If there is a problem with the system
a message will appear for a few sec-
onds. Have the vehicle checked by
an authorized HYUNDAI dealer.
The LFA system will not be in the
ASSIST state when :
The turn signal is turned on before
changing a lane. If you change
lanes without the turn signal on,
the steering wheel might be con-
trolled.
The vehicle is not driven in the mid-
dle of the lane when the system is
turned on or right after changing a
lane.
ESC (Electronic Stability Control) or
VSM (Vehicle Stability Management)
is activated.
The vehicle is driven on a sharp
curve with high speed.
Vehicle speed is over 90 mph (145
km/h).
The vehicle makes sharp lane
changes.
The vehicle brakes suddenly.
Only one lane marker is detected.
The lane is very wide or narrow.
Radius of a curve is too small.
The vehicle is driven on a steep
incline.
The steering wheel is turned sud-
denly.

The driver is responsible for
accurate steering.
Turn off the system and drive
the vehicle in following situa-
tions.
- In bad weather
- In bad road condition
- When the steering wheel
needs to be controlled by the
driver frequently.

Limitations of the system
The LFA system may operate prema-
turely even if the vehicle does not
depart from the intended lane, OR,
the LFA system may not assist your
steering if the vehicle leaves the
intended lane under the following cir-
cumstances:
When the lane and road condi-
tions are poor
It is difficult to distinguish the lane
marking from the road surface or
the lane marking is faded or not
clearly marked.
It is difficult to distinguish the color
of the lane marker from the road.
There are markings on the road
surface that look like a lane marker
that is inadvertently being detected
by the camera.
The lane marker is indistinct or
damaged.
The lane marker is merged or
divided. (e.g. tollgate) The lane number increases or
decreases or the lane marker are
crossing complicatedly.
There are more than two lane
markers on the road in front of you.
The lane marker is very thick or
thin.
The lane marker ahead is not visi-
ble due to rain, snow, water on the
road, damaged or stained road
surface, or other factors.
The shadow is on the lane marker
by a median strip, trees, guardrail,
noise barriers, etc.
The lane markers are complicated
or a structure substitutes for the
lines such as a construction area.
There are crosswalk signs or other
symbols on the road.
The lane suddenly disappears
such as at the intersection.When external condition is inter-
vened
The brightness outside changes
suddenly such as when entering or
exiting a tunnel, or when passing
under a bridge.
The brightness outside is too low
such as when the headlamps are
not on at night or the vehicle is
going through a tunnel.
There is a boundary structure in
the roadway such as a concrete
barrier, guardrail and reflector post
that is inadvertently being detected
by the 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.
There is not enough distance
between you and the vehicle in
front to be able to detect the lane
marker or the vehicle ahead is driv-
ing on the lane marker.

The Driver Attention Warning sys-
tem utilizes the camera sensor on
the front windshield for its opera-
tion. To keep the camera sensor in
the best condition, you should
observe the followings:
Do not disassemble the camera
temporarily to tint the window or
to attach any types of coatings
and accessories. If you disas-
semble a camera and assemble
it again, take your vehicle to an
authorized HYUNDAI dealer and
have the system checked for cal-
ibration.
NEVER install any accessories
or stickers on the front wind-
shield, nor tint the front wind-
shield.
NEVER locate any reflective
objects (i.e. white paper, mirror)
over the dashboard. Any light
reflection may cause a malfunc-
tion of the Driver Attention Alert
(DAW) system.
Pay extreme caution to keep the
camera sensor out of water.
NOTICE
The Driver Attention Warning
(DAW) system may not properly
operate with limited alerting in
the following situations:
The lane detection perform-
ance is limited. (For more
details, refer to "Lane Keeping
Assist (LKA) system" in this
chapter.)
The vehicle is violently driven
or is abruptly turned for obsta-
cle avoidance (e.g. construc-
tion area, other vehicles, fallen
objects, bumpy road).
Forward drivability of the vehi-
cle is severely undermined
(possibly due to wide variation
in tire pressures, uneven tire
wear-out, toe-in/toe-out align-
ment).
The vehicle drives on a curvy
road.
The vehicle drives on a bumpy
road.
The vehicle drives through a
windy area.
The vehicle is controlled by the
following driving assist sys-
tems:
- Lane Keeping Assist (LKA)
system
- Forward Collision-Avoidance
Assist (FCA) system
- Smart Cruise Control (SCC)
system
- Lane Following Assist (LFA)
system
CAUTION
Playing the vehicle audio sys-
tem at high volume may offset
the Driver Attention Warning
(DAW) system warning sounds.
CAUTION

If you have a flat tire while
driving
If a tire goes flat while you are driv-
ing:
1. Take your foot off the accelerator
pedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause a loss of con-
trol. When the vehicle has slowed
to such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the medi-
an area between the two traffic
lanes.
2. When the vehicle is stopped, turn
on your emergency hazard flash-
ers, set the parking brake and shift
gear to the P(Park) position.
3. Have all passengers get out of the
vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
If the vehicle stalls while driv-
ing
1. Reduce your speed gradually,
keeping a straight line. Move cau-
tiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the vehicle again. If
your vehicle will not start, contact
an authorized HYUNDAI dealer. Be sure the shift lever is in P
(Park). The vehicle starts only
when the shift lever is in P (Park).
This vehicle does not have a regu-
lar 12V battery that needs periodic
replacement. It is lithium ion poly-
mer type integrated into the high
voltage battery. The vehicle has a
12V battery protection system that
cuts 12V battery from vehicle draw
to prevent full discharge. If vehicle
will not start, first try pressing the
12V Battery Reset switch (left side
of the steering wheel near the fuel
door open switch) to reconnect the
12V battery, but you must start
vehicle within 15 seconds of press-
ing the 12V Battery Reset switch.
After starting vehicle, operate the
vehicle safely outdoors in ready
mode stopped and/or drive it for 30
minutes total to charge the 12V
battery fully.
Check the fuel level and add fuel if
necessary.
Do not push or pull the vehicle to
start it.
If the vehicle still does not start, call
an authorized HYUNDAI dealer for
assistance.
