Adjusting the driver and passenger
side temperature equally
1. Press the DUAL button again to
deactivate DUAL mode. The pas-
senger side temperature will be
set to the same temperature as
the driver side temperature.
2. Operate the driver side tempera- ture control switch. The driver and
passenger side temperature will
be adjusted equally. Temperature conversion
You can switch the temperature
mode between Fahrenheit and
Centigrade as follows:
While pressing the OFF, press the
AUTO button for 3 seconds or more.
The display will change from
Fahrenheit to Centigrade, or from
Centigrade to Fahrenheit.
The temperature unit (from °C to °F
or from °F to °C) can be changed by
using the “User Settings” mode of the
LCD display.
If the battery has been discharged or
disconnected, the temperature mode
display will reset to Fahrenheit.
WARNING- Reduced
Visibility
Continuous use of the climate
control system in the recirculat-
ed air position may allow
humidity to increase inside the
vehicle which may fog the glass
and obscure visibility.
WARNING- Recirculated Air
Continue using the climate con-
trol system in the recirculated
air position can cause drowsi-
ness or sleepiness, and loss of
vehicle control. Set the air
intake control to the outside
(fresh) air position as much as
possible while driving.
WARNING- Sleeping with AC on
Do not sleep in a vehicle with
the air conditioning or heating
system on as this may cause
serious harm or death due to a
drop in the oxygen level and/or
body temperature.

Air conditioning system operation tips
If the vehicle has been parked indirect sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
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.
During air conditioning system operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance. 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 sys-
tem operation characteristic.
Operating the air conditioning sys- tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristic.
If you operate 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 knob or button to
the position and fan speed
control to the lower speed.Climate control air filter
The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system. If
dust or other pollutants accumulate in
the filter over a period of time, the air
flow from the air vents may decrease,
resulting in moisture accumulation on
the inside of the windshield even
when the outside (fresh) air position is
selected. If this happens, have the cli-
mate control air filter replaced by an
authorized Kia dealer.

WINDSHIELD DEFROSTING AND DEFOGGING
For maximum defrosting, set thetemperature control to the extreme
right/hot position and the fan speed
control to the highest speed.
If warm air to the floor is desired while defrosting or defogging, set the
mode to the floor-defrost position.
Before driving, clear all snow and ice from the windshield, rear win-
dow, outside rear view mirrors, and
all side windows.
Clear all snow and ice from the hood and air inlet in the cowl grill to
improve heater and defroster effi-
ciency and to reduce the probabili-
ty of fogging up the inside of the
windshield.Automatic climate control sys-
tem
To defog inside windshield
1. Select desired fan speed.
2. Select desired temperature.
3. Press the defroster button ( ).
4. The outside (fresh) air position will be selected automatically.
If the outside (fresh) air position is
not selected automatically, adjust the
corresponding button manually.

WARNING - Windshield
heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and the
windshield could cause the
outer surface of the windshield
to fog up, causing loss of visi-
bility.

3. Press the defroster button ( ).
4. The outside (fresh) air position will be selected automatically.
Defogging logic
To reduce the probability of fogging
up inside of the windshield, the air
intake or air conditioning are con-
trolled automatically according to
certain conditions such as or
position. To cancel or return to the
defogging logic, do the followings:
Automatic climate control system

Wet brakes may impair the vehicle’s
ability to safely slow down; the vehi-
cle may also pull to one side when
the brakes are applied. Applying the
brakes lightly will indicate whether
they have been affected in this way.
To dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.In the event of brake failure
If service brakes fail to operate while
the vehicle is in motion, you can
make an emergency stop with the
parking brake. The stopping dis-
tance, however, will be much greater
than normal.
Disc brakes wear indicator
When your brake pads are worn and
new pads are required, you will hear
a high-pitched warning sound from
your front brakes or rear brakes (if
equipped). You may hear this sound
come and go or it may occur when-
ever you depress the brake pedal.
Please remember that some driving
conditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
Always replace the front or rear
brake pads as pairs.
CAUTION - Replace brake
pads
Do not continue to drive withworn brake pads. Continuing todrive with worn brake pads candamage the braking system andresult in costly brake repairs.
WARNING - Parking brake
Avoid applying the parking
brake to stop the vehicle while it
is moving except in an emer-
gency situation. Applying the
parking brake while the vehicle
is moving at normal speeds can
cause a sudden loss of control
of the vehicle. If you must use
the parking brake to stop the
vehicle, use great caution in
applying the brake.
