Freshens a vehicle’s inner space by
deodorization of lingering odor through
PCM installed in HVAC system.
Your Genesis is equipped with the PCM
which includes a visible ray LED and
photo-catalytic material. The PCM is
activated automatically when the vehicle
is started.
The PCM deodorizes harmful gases
such as NH
3 or HCHO and reduces the
number of floating viruses and bacteria
nearby PCM and eventually air inside
cabin of your vehicle will be refreshed
by continuous air flow through PCM
installed in HVAC system.

WARNING
Windshield heating
Do not use the
position during
cooling operation in extremely humid
weather. The difference between the

causing loss of visibility could cause
an accident resulting in serious injury
or death. In this case, set the mode
selection button to the
position
and fan speed control knob to a lower
speed.

[For maximum defrost performance,
set the temperature control to the
highest temperature setting and
the fan speed control to the highest
setting.
