✽
NOTICE
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the temperature gauge indi-
cates engine overheating.
• When opening the windows in humid
weather air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equipment,
air conditioning should only be run
with the windows closed.

Air conditioning system opera-
tion 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.
• To help reduce moisture inside of win-
dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-
ating the air conditioning system.
• During air conditioning system opera-
tion, you may occasionally notice a
slight change in engine speed at idle
as the air conditioning compressor
cycles. This is a normal system opera-
tion characteristic.
• Use the air conditioning system every
month if only for a few minutes to
ensure maximum system perform-
ance.
• When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even pudding) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.• The air conditioning system includes a
function that automatically turns the air
conditioning compressor off if engine
coolant temperature approaches an
over heating level. The air conditioning
compressor operation will resume
once engine coolant temperature
returns to the normal range. Also, the
air conditioning compressor is auto-
matically turned off for a few seconds
when the accelerator is fully depressed
(wide open throttle).
• When operating the air conditioning
system use the outside (fresh) air posi-
tion.
• Operating the air conditioning system
in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a bad influ-
ence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized Kia dealer.
✽
NOTICE
When the performance of the air condi-
tioning system is reduced it is important
that the correct type and amount of oil
and refrigerant is used. Otherwise,
damage to the compressor and abnor-
mal system operation may occur.
CAUTION
The air conditioning system should
be serviced by an authorized Kia
dealer. Improper service may cause
serious injury.

4. The outside (fresh) air and air condi-
tioning will be selected.
To reduce the probability of fogging up
the inside of the windshield, the air intake
control is set to the outside (fresh) air
position automatically and the air condi-
tioning will automatically operate if the
mode is selected to the or posi-
tion. If you don't want the air conditioning
and the outside (fresh) air position, press
the corresponding button to cancel the
operation.• For maximum defrosting, set the temper-
ature control to the extreme right/hot posi-
tion and the fan speed control to the high-
est 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 window, 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 efficiency and to reduce the
probability of fogging up inside of the
windshield.
WINDSHIELD DEFROSTING AND DEFOGGING

CAUTION
Do not use the or position
during cooling operation in
extremely humid weather. The dif-
ference between the temperature of
the outside air and that of the wind-
shield could cause the outer sur-
face of the windshield to fog up,
causing loss of visibility. In this
case,set the mode selection knob
to the position and fan speed
control knob to the lower speed.

In case of an emergency
4. The coolant level should then be
checked. If the level in the reservoir is
low, look for leaks at the radiator hoses
and connections, heater hoses and
connections, radiator, and water
pump. If you find a major leak or anoth-
er problem that may have caused the
engine to overheat, do not operate the
engine until it has been corrected. Call
an authorized Kia dealer for assis-
tance. If you do not find a leak or other
problem, carefully add coolant to the
reservoir.
If the engine frequently overheats, have
the cooling system checked and repaired
by an authorized Kia dealer.
Jump starting
Jump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting proce-
dures. If in doubt, we strongly recom-
mend that you have a competent techni-
cian or towing service jump start your
vehicle.
✽
NOTICE
Use only a 12-volt jumper system. You
can damage a 12-volt starting motor,
ignition system, and other electrical
parts beyond repair by use of a 24-volt
power supply (either two 12-volt batter-
ies in series or a 24-volt motor generator
set).
WARNING- Removing
radiator cap
Do not remove the radiator cap
when the engine and radiator are
hot. Scalding hot coolant and steam
may blow out under pressure. This
could cause serious injury.
EMERGENCY STARTING
WARNING- Battery
• Keep all flames or sparks away
from the battery. The battery pro-
duces hydrogen gas which may
explode if exposed to flame or
sparks.
• Do not attempt to jump start the
vehicle if the discharged battery
is frozen or if the electrolyte level
is low;the battery may rupture or
explode.
WARNING- Battery
Never attempt to check the elec-
trolyte level of the battery as this
may cause the battery to rupture or
explode causing serious injury.

ENGINE COOLING SYSTEM
The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.
Checking the coolant level
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine is
cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorized
Kia dealer for a cooling system inspec-
tion.
WARNING- Removing
radiator cap
• Never attempt to remove the radi-
ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.
(Continued)
(Continued)
• Turn the engine off and wait until
it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
• Even if the engine is not operat-
ing, do not remove the radiator
cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.
