Switching to Hybrid mode to allow
heating or air conditioning (Plug-in
hybrid vehicle)
OAEPHQ049842LOAEPHQ049842L
This message is displayed when the
vehicle automatically switches to
HEV mode to allow heating or air
conditioning. It is when the coolant
temperature is low (below -14°C) and the
driver turns on the heating or cooling
system.
If the coolant temperature gets higher
than -14°C or the driver turns off the
heating or cooling system the vehicle
returns to its default (EV) mode.

heating or air conditioning (Plug-in
hybrid vehicle)
OAEPHQ049841LOAEPHQ049841L
This message is displayed when the
vehicle maintains the HEV mode to allow
heating or air conditioning. The mode
does not change when the driver presses
the [HEV] button to switch from the HEV
mode to EV mode while the heating and
cooling system is on and the coolant
temperature is below -14°C.

Seats & Safety System3-20

[ Auto Comfort Control (for driver’s
seat) (if equipped)
- The seat warmer automatically controls the seat temperature
depending on the ambient
temperature and the set climate
control temperature when the
engine is running. If the seat
warmer switch is pushed, the seat
warmer will have to be controlled
manually.
To use this function, it must be
activated from the Settings menu in
the infotainment system screen.
- The seat warmer defaults to the OFF position whenever the ignition
switch is ON. However, if the Auto
Comfort Control function is ON, the
driver’s seat warmer will turn on
and off depending on the ambient
temperature and the set climate
control temperature.
For more details, refer to the separately
supplied Infotainment manual with
your vehicle.
Information
With the seat warmer switch in the ON
position, the heating system in the seat
turns off or on automatically depending on
the seat temperature.
Air Ventilation Seat (if equipped)
ONX4030027
The air ventilation seats are provided
to cool the front seats by blowing air
through small vent holes on the surface
of the seat cushions and seatbacks.
When the operation of the air ventilation
seat is not needed, keep the switches in
the OFF position.
While the engine is running, push the
switch to cool the driver's seat or the
front passenger's seat (if equipped).
NOTICE
To prevent damage to the air ventilation
seats:

[ Never use a solvent such as paint
thinner, benzene, alcohol or gasoline
to clean the seats.

[ Avoid spilling liquids on the surface
of the front seats and seatbacks; this
may cause the air vent holes to block
and not work properly.

[ Do not place materials such as
plastic bags or newspapers under
the seats. They may block the air
intake causing the malfunction of the
air vent.

[ Do not change the seat covers. It may
damage the air ventilation seat.

[ If the air vents do not operate, restart
the vehicle. If there is no change,
Have your vehicle inspected by an
authorized HYUNDAI dealer.
