sensor GENESIS G90 2021 Workshop Manual

Information
The system can detect a pedestrian or
an object when:
- A pedestrian is standing behind the
vehicle.
- A large obstacle, such as a vehicle, is
parked in the rear center of the
vehicle.
Detecting Sensor
Rear view camera
The rear view camera acquires
images for rear pedestrian detection.
If the camera lens is covered with
snow, rain, or a foreign substance,
the system may not work properly.
Always keep the camera lens clean.
Rear ultrasonic sensors
The rear ultrasonic sensors detect
objects. The sensors are installed in
the rear bumper. If the rear ultrason-
ic sensor(s) is covered with snow,
rain, or a foreign substance, the sys-
tem may not work properly. Always
keep the rear bumper clean.

Lane changing
• A vehicle which moves into your
lane from an adjacent lane cannot
be recognized by the sensor until it
is in the sensor's detection range.
• The radar may not detect immedi-
ately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.
• If a slower vehicle moves into your
lane, your speed may decrease to
maintain the distance to the vehicle
ahead.
• If a faster vehicle which moves into
your lane, your vehicle will acceler-
ate to the set speed.
Vehicle recognition
Some vehicles in your lane cannot
be recognized by the sensor:
- Vehicles offset to one side
- Slow-moving vehicles or sudden-
decelerating vehicles
- Stopped vehicles
- Vehicles with small rear profile
such as trailers with no loads
A vehicle ahead cannot be recog-
nized correctly by the sensor if any of
following occurs:
- When the vehicle is pointing
upwards due to overloading in the
luggage compartment
- While the steering wheel is operat-
ing
- When driving to one side of the
lane
- When driving on narrow lanes or
on curves
Apply the brake or accelerator pedal
if necessary.

• There are crosswalk signs or other
symbols on the road.
• The lane marker in a tunnel is
stained with oil, etc.
• 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.• Driving on a steep grade, over a
hill, or when driving on a curved
road.
• The adverse road conditions cause
excessive vehicle vibrations while
driving.
• The surrounding of the inside rear
view mirror temperature is high
due to direct sunlight, etc.

LKA operation
To activate/deactivate the LKA sys-
tem:
With the Engine Start/Stop button in
the ON or START position, press the
LKA system switch located on the
instrument panel on the left hand
side of the steering wheel. The indi-
cator in the instrument cluster will ini-
tially illuminate ( ) white. This
indicates the LKA system is in the
READY but NOT ENABLED state.
If you press the LKA switch again,
the indicator on the cluster will go off.
Note that the vehicle
speed must be at least
approximately 40 mph
(64 km/h) to ENABLE the
LKA system. The indicator in the
cluster will illuminate green.
The color of indicator will change
depending on the condition of LKA
system.
- White :Sensor does not detect
lane markers or vehicle
speed is under 40 mph (64
km/h).
- Green : Sensor detects lane mark-
ers and the system is able
to control vehicle steering.
• The system helps detect 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.
• If any other warning sound
such as seat belt warning
chime is already generated,
the Lane Keeping Assist sys-
tem warning may not sound.
• Do not place objects on the
dashboard that reflects light
such as mirrors, white paper,
etc. This may prevent the LKA
system from functioning
properly.
• Always have your hands on
the steering wheel while the
LKA system is activated.
• 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.
