2020 Hyundai Sonata warning light

While Driving6-60
• When you replace the windshield
glass, LKA system camera or related
parts of the steering wheel, have the
vehicle inspected by an authorized
HYUNDAI dealer and have the system
checked for 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.
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. •
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.

vehicle departs from the projected
lane in front of you, LKA system
operates as follows:

1. A visual warning appears on the cluster LCD display. Either the left
lane marker or the right lane marker
in the cluster LCD display will blink
depending on which direction the
vehicle is veering. 2. LKA system will help control the
vehicle’s steering to prevent the
vehicle from crossing the lane maker
in below conditions.
- Vehicle speed is over 40 mph (64 km/h)
- The system detects both lane markers
- When driving, the vehicle is located between both lanes normally.
- The steering wheel is not turned suddenly.
When lanes are detected and all the
conditions to activate LKA system are
satisfied, LKA system indicator light
(
) will change from white to green.
This indicates that LKA system is in the
ENABLED state and the steering wheel
will be controlled.

Keep hands on steering wheel
If the driver takes their hands off the
s
teering wheel for several seconds while
LKA system is activated, the system will
warn the driver.
Information
If the steering wheel is held very lightly
the message may still appear because LKA
system may not recognize that the driver
has their hands on the wheel.
WARNING
The warning message may appear
late according to road conditions.
Therefore, always have your hands on
the steering wheel while driving.

Driver’s hands not detected.
LKA system is disabled temporarily
If the driver still does not have their
hands on the s
teering 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.

WARNING
• The warning light on the side view
mirror will illuminate whenever a
vehicle is detected at the rear side by
the system.
To avoid accidents, do not focus only
on the warning light and neglect to
see the surrounding of the vehicle.
• Drive safely even though the
vehicle is equipped with Blind-Spot
Collision-Avoidance Assist system.
Do not solely rely on the system
but check your surrounding before
changing lanes or backing the
vehicle up.
• The system may not alert the driver
in some conditions so always check
your surroundings while driving.
CAUTION
• The driver should always use
extreme caution while operating
the vehicle, whether or not the
warning light on the side view mirror
illuminates or there is a warning
alarm.
• Playing the vehicle audio system at
high volume may offset the Blind-
Spot Collision Warning system
warning sounds.
• The warning of Blind-Spot Collision-
Avoidance Assist system may not
sound while other system’s warning
sounds.
Blind-Spot Collision-Avoidance
Assist
Blind-Spot Collision-Avoidance Assist
system may apply braking power, when
an approaching vehicle is detected
within a certain distance next to or
behind your vehicle.
It gently applies braking power on the
tire, which is located in the opposite
side of the possibly-colliding point. The
instrument cluster will inform the driver
of the system activation.
Blind-Spot Collision-Avoidance Assist
system is automatically deactivated
when:
- The vehicle drives a certain distance away
- The vehicle direction is changed against the possible-colliding point
- The steering wheel is abruptly moved
- The brake pedal is depressed
- After a certain period of time
The driver should drive the vehicle in the
middle of the vehicle lanes to keep the
system in the ready status.
When the vehicle drives too close to one
side of the vehicle lanes, the system may
not properly operate.
In addition, the system may not properly
control your vehicle in accordance with
driving situations. Thus, always pay close
attention to road situations.

Rear corner radar
The rear corner radars are the sensors
inside the rear bumper for detecting the
side and rear areas. Always keep the rear
bumper clean for proper operation of the
system.
CAUTION
• The system may not work properly
when the bumper has been
damaged, or if the rear bumper has
been replaced or repaired.
• The sensing range differs somewhat
according to the width of the road.
When the road is narrow, the system
may detect other vehicles in the next
lane. On the other hand, when the
road is wide, the system may not
detect vehicles on both lanes and
may not warn.
• The system may turn off due to
strong electromagnetic waves.
• Always keep the sensors clean.
• NEVER arbitrarily disassemble the
sensor component nor apply any
impact on the sensor component.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly moved
out of proper alignment, the system
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
dealer. •
Do not apply foreign objects such as
a bumper sticker or a bumper guard
near the radar sensor or apply paint
to the sensor area. Doing so may
adversely affect the performance of
the sensor.
• NEVER install any accessories or
stickers on the front windshield, nor
tint the front windshield.
• Pay extreme caution to keep the
front view camera out of water.
• NEVER locate any reflective objects
(i.e. white paper, mirror) over the
crash pad. Any light reflection may
cause a malfunction of the system.
