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 accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, have the climate control air fil-
ter replaced by an authorized Kia
dealer.

Power outlet (if equipped)
The power outlet is designed to pro-
vide power for mobile telephones or
other devices designed to operate
with vehicle electrical systems. The
devices should draw less than 10
amps with the engine running.
Use the power outlet only when the
engine is running and remove the
accessory plug after use. Using the
accessory plug for prolonged periods
of time with the engine off could
cause the battery to discharge.Only use 12V electric accessories
which are less than 10A in electric
capacity.
Adjust the air-conditioner or heater to
the lowest operating level when
using the power outlet.
Close the cover when not in use.
Some electronic devices can cause
electronic interference when plugged
into a vehicle’s power outlet. These
devices may cause excessive audio
static and malfunctions in other elec-
tronic systems or devices used in
your vehicle.
CAUTION- Vanity mirror
lamp
Close the vanity mirror coversecurely and return the sunvi-sor to its original position afteruse. If the vanity mirror is notclosed securely, the lamp willstay on and could result in bat-tery discharge and possiblesunvisor damage.

Do not put a finger or a foreign
element (pin, etc.) into a power
outlet and do not touch with a
wet hand. You may get an elec-
tric shock.

To use an external USB device,
make sure the device is not con-
nected when starting up the
vehicle. Connect the device after
starting up.
If you start the engine when the USB device is connected, it may
damage the USB device. (USB
flashdrives are very sensitive to
electric shock.)
If the engine is started up or turned off while the external USB
device is connected, the external
USB device may not work.
The System may not play unau- thenticated MP3 or WMA files.
1) It can only play MP3 files with the compression rate
between 8Kbps ~ 320Kbps.
2) It can only play WMA music files with the compression
rate between 8Kbps ~
320Kbps.
Take precautions for static elec- tricity when connecting or discon-
necting the external USB device.
(Continued)(Continued)
An encrypted MP3 PLAYER is
not recognizable.
Depending on the condition of the external USB device, the
connected external USB device
can be unrecognizable.
When the formatted byte/sector setting of External USB device is
not either 512BYTE or
2048BYTE, then the device will
not be recognized.
Use only a USB device format- ted to FAT 12/16/32.
USB devices without USB I/F authentication may not be recog-
nizable.
Make sure the USB connection terminal does not come in con-
tact with the human body or
other objects.
If you repeatedly connect or dis- connect the USB device in a
short period of time, it may break
the device.
(Continued)(Continued)
You may hear a strange noise
when connecting or disconnect-
ing a USB device.
If you disconnect the external USB device during playback in
USB mode, the external USB
device can be damaged or may
malfunction. Therefore, discon-
nect the external USB device
when the audio is turned off or in
another mode. (e.g, Radio, CD)
Depending on the type and capacity of the external USB
device or the type of the files
stored in the device, there is a
difference in the time for recogni-
tion the device.
Do not use the USB device for purposes other than playing
music files.
Playing videos through the USB is not supported.
Use of USB accessories such as rechargers or heaters using USB
I/F may lower performance or
cause trouble.

Driving your vehicle
Be sure the exhaust system
does not leak.
The exhaust system should be
checked whenever the vehicle is
raised to change the oil or for any
other purpose. If you hear a change
in the sound of the exhaust or if you
drive over something that strikes the
underneath side of the vehicle, have
the exhaust system checked as soon
as possible by an authorized Kia
dealer.
WARNING - Engineexhaust
Do not inhale exhaust fumes or
leave your engine running in an
enclosed area for a prolonged
time.
Exhaust fumes contain carbon
monoxide, a colorless, odorless
gas that can cause uncon-
sciousness and death by
asphyxiation.
WARNING - Open trunk
Do not drive with the trunk
open.
Poisonous exhaust gases can
enter the passenger compart-
ment. If you must drive with the
trunk open proceed as follows:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at
"Floor" or "Face" and the fan
at the highest speed.WARNING - California
