AFLS (Adaptive Front LightingSystem) a.k.a. DBL (Dynamic Bending Light)
Adaptive front lighting system uses
the steering angle and vehicle
speed, to keep your field of vision
wide by swiveling and leveling the
headlamp.
Change the switch to the AUTO posi-
tion when the engine is running. The
adaptive front lighting system will
operate when the headlamp is ON.
To turn off the AFLS, change the
switch to other positions. After turn-
ing the AFLS off, headlamp swiveling
no longer occurs, but leveling oper-
ates continuously.
If the AFLS malfunction indicator
comes on, the AFLS is not working
properly. Drive to the nearest safe
location and restart the engine. If the
indicator continuously remains on,
we recommend that the system be
checked by an authorized retailer of
Genesis Branded products.

the operation that the parking lamp
or headlamp is turned on automat-
ically in the AUTO light position.

AUTO (Automatic) control
The rain sensor located on the upper
end of the windshield glass senses
the amount of rainfall and controls
the wiping cycle for the proper inter-
val. The more it rains, the faster the
wiper operates.
When the rain stops, the wiper stops.
To vary the speed setting, turn the
speed control knob (B).
If the wiper switch is set in AUTO
mode when Engine Start/Stop button
is in the ON position, the wiper will
operate once to perform a self-check
of the system. Set the wiper to OFF
position when the wiper is not in use. When washing the vehicle, set
the wiper switch in the OFF (O)
position to stop the auto wiper
operation. The wiper may oper-
ate and be damaged if the switch
is set in the AUTO mode while
washing the vehicle.
Do not remove the sensor cover located on the upper end of the
passenger side windshield
glass. Damage to system parts
could occur and may not be cov-
ered by your vehicle warranty.
There may be a malfunction with the wiper sensor while operating
in the AUTO mode, when there
are interruptions by foreign sub-
stances, such as small pebbles,
dust, or insects, or when an out-
side brightness is abruptly
changed while driving.
There may be a malfunction with the wiper sensor in detecting a
rainfall amount, when the front
windshield is coated with wax,
or when the wiper blades are
worn out.
NOTICE
To avoid personal injury from
the windshield wipers, when the
engine is running and the wind-
shield wiper switch is placed in
the AUTO mode:
Do not touch the upper end ofthe windshield glass facing
the rain sensor.
Do not wipe the upper end of the windshield glass with a
damp or wet cloth.
Do not put pressure on the windshield glass.

To charge a cellular phone
The wireless cellular phone charging
system charges only the Qi-enabled
cellular phones ( ). Read the label
on the cellular phone accessory
cover or visit your cellular phone
manufacturer’s website to check
whether your cellular phone supports
the Qi technology.
The wireless charging process starts
when you put a Qi-enabled cellular
phone on the wireless charging unit.
1. Remove other items, including thesmart key, from the wireless charg-
ing unit. If not, the wireless charg-
ing process may be interrupted.
2. The indicator illuminates in orange during the charging process. The
indicator color changes to green,
when the charging process is
completed.
3. You can turn ON or OFF the wire- less charging function in the user
settings mode on the instrument
cluster. (For further information,
refer to the "LCD Modes" in this
chapter.)
Slightly change the cellular phone
position, when the cellular phone is
not being charged. Make sure that
the indicator illuminates in orange.
The indicator color may not change
to green in accordance with the cel-
lular phone type, even though the
charging process is completed. The
indicator blinks in orange for 10 sec-
onds when there is a malfunction
with the wireless charging system. In
this case, temporarily stop the charg-
ing process, and re-attempt to wire-
lessly charge your cellular phone
again. The system warns you with a mes-
sage on the LCD display when you
do not take out the cellular phone
from the wireless charging unit with
the front door open and the Engine
Start/Stop button in the OFF posi-
tion.
The wireless cellular phone
charging system may not sup-
port certain cellular phones,
which are not verified for the Qi
specification ( ).
Locate your cell phone well in the middle of the wireless cellular
phone charging system. Even
when your cell phone locates
slightly to one side, the charging
speed may decrease.
The wireless charging process may temporarily stop, when a
smart key function operates (i.e.
starting the engine, opening the
doors, closing the doors).
For certain cell phones, the indi- cator color may not change to
green, even when the wireless
charging process is properly
completed.
The wireless charging process may temporarily stop, when tempera-
ture abnormally increases inside
the wireless cellular phone charg-
ing system. The wireless charging
process restarts, when tempera-
ture falls to a proper level.
The wireless charging processmay temporarily stop when there
is any metallic item, such as a
coin, between the wireless cellu-
lar phone charging system and a
cellular phone.
