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
recirculation 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 windows
and sunroof closed.
• During air conditioning system
operation, you may occasionally
notice a slight change in engine speed
as the air conditioning compressor
cycles. This is a normal system
operation characteristic.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system
performance.
• When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side of
the vehicle. This is a normal system
operation characteristic.
• If you operate the 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 button to
the
position and set the fan speed
control knob to the lowest speed
setting.

[C] : Cabin 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 conditioning system.
Have the cabin air filter replaced by an
authorized HYUNDAI dealer according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.
Information
• Replace the filter according to the
Maintenance Schedule.
• If the car is being driven in severe
conditions such as dusty, rough
roads, more frequent cabin air filter
inspections and changes are required.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by an authorized
HYUNDAI dealer.
