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)
OTM030003
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 become blocked 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 air vents to not
work properly.
• 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,
we recommend that you have your
vehicle inspected by an authorized
HYUNDAI dealer.

OTM050053
During power opening or closing if the
power liftgate senses any obstacle, the
power liftgate will stop and move in the
opposite direction.
The auto reverse function may not work
if objects are too soft or thin, or if the
liftgate is almost fully closed near the
latched position.
Caution should be taken to prevent any
objects from obstructing the liftgate
opening.
If the automatic reverse feature operates
more than two times while attempting
to open or close the liftgate, the power
liftgate may stop at that position.
WARNING
Never intentionally place any object
or part of your body in the path of
the power liftgate to make sure the
automatic reverse function operates.
NOTICE
Do not put heavy objects on the power
liftgate before you operate the power
liftgate. Additional weight may damage
the operation of the system.

conditioning or heating system on. It
may cause serious harm or death due
to a drop in the oxygen level and/or
body temperature.
• Continued climate control system
