Convenient features of your vehicle
When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic when
outside temperatures are high. Air
conditioning system operation
when climbing a steep grade or in
high outside ambient temperatures
can cause engine overheating.
Continue to use the fan, but turn
the air conditioning system off if
the engine temperature gauge
indicates engine overheating.
Air conditioning system operation
tips
• If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
• After sufficient cooling has been
achieved, switch back from recir-
culation mode to fresh mode.
• To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the win-
dows and sunroof closed.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance.
• If you operate air conditioner
excessively, the difference between
the temperature of the outside air
and that of the windshield could
cause the outer surface of the
windshield to fog up, causing loss
of visibility. In this case, set the
mode selection knob or button to
the position and fan speed
control to the lowest speed.
System Maintenance
Cabin air filter
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or
other pollutants that enter the vehicle
through the heating and air condi-
tioning system.
Have the cabin air filter replaced by
an authorized retailer of Genesis
Branded products according to the
maintenance schedule. If the vehicle
is being driven in severe conditions
such as dusty or rough roads and/or
if transporting pets or occupants
smoke inside the vehicle, then more
frequent cabin air filter inspections
and changes are required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized retailer of Genesis
Branded products.

Wireless Cellular Phone
Charging System (if equipped)
On certain models, the vehicle
comes equipped with a wireless cel-
lular phone charger.
The system is available when all
doors are closed, and when the
Engine Start/Stop button is in the
ACC, ON or START position.
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 the
smart key, from the wireless charg-
ing unit. If not, the wireless charg-
ing process may be interrupted.
Place the cellular phone on the
center of the charging pad ( ).
2. The indicator light is orange when
the cellular phone is charging. The
indicator light turns green when
phone charging is complete.3. You can turn ON or OFF the wire-
less charging function from the
Settings menu in the AVN system
screen. Select:
- Setup →Vehicle Settings →
Convenience →Wireless
Charging
For detailed information, scan the
QR code in a separately supplied
simple manual.
If your cellular phone is not charging:
- Slightly change the position of the
cellular phone on the charging
pad.
- Make sure the indicator light is
orange.
The indicator light will blink orange for
10 seconds if there is a malfunction in
the wireless charging system.
In this case, temporarily stop the
charging process, and re-attempt to
charge your cellular phone again.
The system warns you with a mes-
sage on the LCD display if the cellular
phone is still on the wireless charging
unit after the engine is turned OFF
and the front door is opened.
For some manufacturers' cellular
phones, the system may not warn
you even though the cellular phone is
left on the wireless charging unit. This
is due to the particular characteristic
of the cellular phone and not a mal-
function of the wireless charging.
