Forward Collision-Avoidance Assist
system is designed to detect the
vehicle, a pedestrian or cyclist ahead (if
equipped) in the roadway through front
radar signals and front view camera
recognition to warn the driver that a
collision is imminent, and if necessary,
apply emergency braking.
WARNING
Take the following precautions when
using Forward Collision-Avoidance
Assist system: • This system is only a supplemental
system and it is not intended to,
nor does it replace the need for
extreme care and attention of
the driver. The sensing range and
objects detectable by the sensors
are limited. Pay attention to the road
conditions at all times.
• Drive at posted speed limits and
accordance to road conditions.
• Always drive cautiously to prevent
unexpected and sudden situations
from occurring. FCA does not always
stop the vehicle completely.
System Setting and Activation

Prerequisite for activation
FCA gets ready to be activated, when
‘Active Assist’ or ‘Warning Only’ under
Forward Safety is selected in the cluster
LCD display, and when the following
prerequisites are satisfied.
- ESC (Electronic Stability Control) is on.
- Vehicle speed is over 10 km/h (6 mph).
(FCA is only activated within a certain
speed range.)
- The system detects a pedestrian, cyclist or a vehicle in front, which may
collide with your vehicle. However,
FCA may not be activated or may only
sound a warning alarm depending on
the driving or vehicle conditions.
FCA may not operate properly according
to the frontal situation, condition of the
vehicle, the direction of pedestrian or
cyclist or speed. If you select "Warning
Only", only warnings occur.
WARNING
To avoid driver distractions, do not
attempt to set or cancel FCA while
driving the vehicle. Always completely
stop the vehicle at a safe place before
setting or canceling the system.
FCA automatically activates upon
placing the ignition switch to the ON
position. The driver can deactivate FCA
by canceling the system setting on the
cluster LCD display or infotainment
system display (if equipped).
FCA automatically deactivates upon
canceling ESC (Electronic Stability
Control). When ESC is canceled, FCA
cannot be activated in the LCD display
or infotainment system display (if
equipped). In this situation, the FCA
warning light will illuminate which is normal.
FCA Warning Message and Brake
Control
FCA produces warning messages,
warning alarms, and emergency braking
based on the level of risk of a frontal
collision, such as when a vehicle ahead
suddenly brakes, or the system detects
that a collision with a pedestrian or
cyclist is imminent.

Do not place objects on the
dashboard that reflects light such as
mirrors, white paper, etc. This may
prevent LKA system from functioning
properly.
• 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 message
appears, the system will stop
controlling the steering wheel.
• The steering wheel is not
continuously 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.
LKA Operation
ODN8069059
To activate/deactivate LKA system:
With the ignition switch in the ON
position, press LKA system button
located on the instrument panel on the
left hand side of the steering wheel. The
indicator in the cluster
display will initially illuminate white. This
indicates LKA system is in the READY but
NOT ENABLED state.
Note that the vehicle speed
must be at least approximately
64 km/h (40 mph) to ENABLE
LKA system. The indicator in the
cluster display will illuminate
green.
- White: Sensor does not detect lane markers or vehicle speed is under 64
km/h (40 mph).
- Green: Sensor detects lane markers and the system is able to control
vehicle steering.
Information
If the indicator (white) is activated from
the previous ignition cycle, the system will
turn ON without any additional control.
If you press the LKA button again, the
indicator on the cluster goes off.

Driver’s hands not detected.
LKA system is disabled temporarily
If the driver still does not have their
hands on the steering wheel after the
message “Keep hands on steering
wheel”, the system will not control the
steering wheel and warn the driver
only when the driver crosses the lane
markers.
However, if the driver has their hands on
the steering wheel again, the system will
start controlling the steering wheel.
WARNING
• LKA system is a supplemental system
only. It is the responsibility of the
driver to safely steer the vehicle and
to maintain it in its lane.
• Turn off LKA system and drive
without using the system in the
following situations:
- In bad weather
- In bad road conditions
- When the steering wheel needs
to be controlled by the driver
frequently
Information
Even though the steering is assisted by the
system, the driver can still steer to control the steering wheel.
The steering wheel may feel heavier when the steering wheel is assisted by the system than when it is not.

Winter Precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 8. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Change to "winter weight" oil if necessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See chapter 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the
battery and cables as described in
chapter 8. The level of charge in your
battery can be checked by an authorized
HYUNDAI dealer or a service station.Check spark plugs and ignition
system
Inspect your spark plugs as described in
chapter 8 and replace them if necessary. Also check all ignition wiring and
components to be sure they are not
cracked, worn or damaged in any way.
Use approved window washer anti-
freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types
of antifreeze as these may damage the
paint finish.
Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when
there is an accumulation of snow or
ice around or near the rear brakes or
if the brakes are wet. If there is a risk
the parking brake may freeze, apply
it only temporarily while you put the
gear selector lever in P and block the
rear wheels so the car cannot roll. Then
release the parking brake.
