• Auto Comfort Control (for driver’s
seat) (if equipped)
- The seat w

armer 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 AV/AVN system screen.
- The seat w

armer 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,
we recommend your vehicle to be
inspected by an authorized HYUNDAI
dealer.

Automatic reverse
ONX4050030
During power opening and closing if the
power liftgate is blocked by an object or
part of the body, the power liftgate will
detect the resistance.
• If the resistance is detected while
opening the liftgate, it will stop and
move in the opposite direction.
• If the resistance is detected while
closing the liftgate, it will stop and
move in the opposite direction.
However, if the resistance is weak such
as from an object that is thin or soft, or
the liftgate is near the latched position,
the automatic stop and reversal may not
detect the resistance. If the automatic
reversal feature operates continuously
more than twice during opening or
closing operation, the power liftgate may
stop at that position. At this time, close
the liftgate manually and operate the
liftgate automatically again.
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.
Non-operating conditions of the
power liftgate
• The power liftgate does not open
when the vehicle is in motion.
The chime will sound if you drive
over 2mph (3km/h) with the
liftgate opened. Stop your vehicle
immediately at a safe place and check
if your liftgate is opened.
• Operating the power liftgate more
than 5 times continuously could
cause damage to the operating motor.
If this occurs, the power liftgate
system enters into thermal protection
mode to prevent the motor from
overheating. In thermal protection
mode, the power liftgate will not
operate. If any of the power liftgate
buttons are pressed to try to open the
liftgate, the chime will sound 3 times
but the liftgate will not operate.
Allow the power liftgate system
to cool for about 1 minute before
operating the system again.
• The power liftgate can be operated
when the engine is not running.
However the power liftgate operation
consumes large amounts of vehicle
electric power. To prevent the battery
from being discharged, do not
operate it excessively e.g.: more than
approximately 10 times repeatedly.
• To prevent the battery from being
discharged, do not leave the power
liftgate in the open position for a long
lime.
• When jacking up the vehicle to
change a tire or repair the vehicle, do
not operate the power liftgate. This
could cause the power liftgate to
operate improperly.
• In cold and wet climates, the power
liftgate may not work properly due to
freezing conditions.
