Your vehicle may accelerate whena vehicle ahead of you disappears.
When you are warned that the vehicle ahead of you is not detect-
ed, drive with caution. When vehicles are at a standstill
and the vehicle in front of you
changes to the next lane, be care-
ful when your vehicle starts to
move because it may not recog-
nize the stopped vehicle in front of
you. Always look out for pedestrians
when your vehicle is maintaining a
distance with the vehicle ahead.

Driving your vehicle
Always be cautious for vehicles with higher height or vehicles car-
rying loads that sticks out from the
back of the vehicle. When using the Smart Cruise
Control take the following pre-
cautions:
If an emergency stop is nec-
essary, you must apply the
brakes. The vehicle cannot be
stopped by using the Smart
Cruise Control System.
Keep a safe distance accord-
ing to road conditions and
vehicle speed. If the vehicle to
vehicle distance is too close
during a high-speed driving, a
serious collision may result.
Always maintain sufficient
braking distance and deceler-
ate your vehicle by applying
the brakes if necessary.
The Smart Cruise Control
System cannot recognize a
stopped vehicle, pedestrians
or an oncoming vehicle.
Always look ahead cautiously
to prevent unexpected and
sudden situations from occur-
ring.

WARNING (Continued)
Vehicles moving in front of
you with a frequent lane
change may cause a delay in
the system's reaction or may
cause the system to react to a
vehicle actually in an adjacent
lane. Always drive cautiously
to prevent unexpected and
sudden situations from occur-
ring.
Always be aware of the select-
ed speed and vehicle to vehi-
cle distance.
The Smart Cruise Control
System may not recognize
complex driving situations so
always pay attention to driv-
ing conditions and control
your vehicle speed.

NOTICE

5-74
The Lane Keeping Assist System
helps detect the lane markers on the
road with a camera at the front wind-
shield, and assists the driver's steer-
ing to help keep the vehicle in the
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 prevent the
vehicle from moving out of its lane.

Driver is responsible for being
aware of surroundings and
steering the vehicle for safe
driving practices.
Do not steer the steering
wheel suddenly when the
steering wheel is being assist-
ed by the system.
LKAS helps prevent the driver
from moving out of the lane
unintentionally by assisting
the driver's steering. However,
the system is just a conven-
ience function and the steer-
ing wheel is not always con-
trolled. While driving, the driv-
er should pay attention to the
steering wheel.
The operation of the LKAS
can be cancelled or not work
properly according to road
condition and surroundings.
Always be cautious when
driving.
WARNING
Do not disassemble LKAS
camera temporarily for tinted
window or attaching any
types of coatings and acces-
sories. If you disassemble a
camera and assemble it again,
take your vehicle to an author-
ized HYUNDAI dealer and
have the system checked for a
calibration.
When you replace the wind-
shield glass, LKAS camera or
related parts of the steering,
take your vehicle to an author-
ized HYUNDAI dealer and
have the system checked for a
calibration.
The system detects lane
markers and controls the
steering wheel by a camera,
therefore, if the lane markers
are hard to detect, the system
may not work properly.
Always be cautious when
using the system.

LKAS operation
To activate/deactivate the LKAS:
With the ignition switch in the ON
position, press the LKAS button
located on the instrument panel on
the lower left hand side of the driver.
The indicator in the cluster display
will initially illuminate white.
When the indicator(white) activated
in the previous ignition cycle, the
system turns on without any control.
Do not place objects on the
dashboard that reflects light
such as mirrors, white paper,
etc. The system may malfunc-
tion if the sunlight is reflected.
Do not place any accessories
near the rearview mirror.
You may not hear warning
sound of LKAS because of the
excessive audio sound.(Continued)
(Continued)
If you continue to drive with
your hands off the steering
wheel, the LKAS will stop con-
trolling the steering wheel
after the hands off alarm.
After then, if you drive with
your hands on the steering
wheel, the control will be acti-
vated again.
If the vehicle speed is high,
steering torque for assistance
will not be enough to keep
your vehicle within the lane. If
so, the vehicle may move out
of its lane.
If you attach objects to the
steering wheel, the system
may not assist steering.
If you attach objects to the
steering wheel, hands off
alarm may not work properly.
WARNING
(Continued)
When the lane markers are
hard to detect, please refer to
"Limitation of the System".
Do not remove or damage the
related parts of LKAS.

vent the driver from leaving the
lane. However, the driver should
not solely rely on the system
but always check the road con-
ditions when driving.
