Manual climate control systemTo defog inside windshield 1. Select any fan speed.
2. Select desired temperature.
3. Select the or position.
4. The outside (fresh) air position will beselected.
If the outside (fresh) air position is not
selected automatically, press the corre-
sponding button manually.
To defrost outside windshield 1. Set the fan speed to the right position.
2. Set the temperature to the extreme hot position.
3. Select the position.
4. The outside (fresh) air position will be selected. 
For maximum defrosting, set the tem-
perature 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 window, out-
side rear view mirrors, and all side win-
dows.
 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.

Do not use the or position
during cooling operation inextremely humid weather. The dif-ference between the temperature ofthe 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 thiscase, set the mode selection knobto the position and fan speedcontrol knob to the lower speed.

Defogging logicManual climate control systemTo reduce the probability of fogging up
the inside of the windshield, the air intake
control is set to the outside (fresh) air
position automatically if any of following
occur.
The mode is set to the , or
while the ignition switch is turned on.
 The ignition switch is turned off.
 The fan is off.
Press the air intake control button to
select the recirculated air position while
the ignition switch is on. How to cancel or return defogging logic
of manual climate control system
1. Turn the ignition switch to the
“ON”
position.
2. Turn the mode selection knob to the defrost position ( ).
3. Push the air intake control button ( ) at least 5 times within 3 sec-
onds. The indicator light in the air intake control
button ( ) will blink 3 times with 0.5
second of interval. It indicates that the
defogging logic is canceled or returned to
the programmed status.
If the battery has been discharged or dis-
connected, it is reset to the defog logic
status.

Maintenance
CLIMATE CONTROL AIR FILTER (IF EQUIPPED)The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle 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) are position is selected. If this
happens, have the climate control air fil-
ter replaced by an Authorized Kia Dealer.The climate control air filter should be
replaced every 15,000 km (10,000
miles). If the vehicle is operated in the
severely air-polluted cities or on dusty
rough roads for a long period, it should
be inspected more frequently and
replaced earlier. When you try to replace
the air filter by owner maintenance,
replace it performing the following proce-
dure, and in this case, be careful to avoid
damaging other components.

For best battery service : Keep the battery securely mounted.
 Keep the top of the battery clean and
dry.
 Keep the terminals and connections clean, tight, and coated with petroleum
jelly or terminal grease.
 Rinse any spilled electrolyte from the battery immediately with a solution of
water and baking soda.
 If the vehicle is not going to be used for an extended time, disconnect the bat-
tery cables.
Battery recharging Your vehicle has a maintenance-free,
calcium-based battery.
 If the battery becomes discharged in ashort time (because, for example, the
headlights or interior lights were left on
while the vehicle was not in use),
recharge it by slow charging (trickle)
for 10 hours.
 If the battery gradually discharges because of high electric load while the
vehicle is being used, recharge it at 20-
30A for two hours.Items to be reset after the battery hasbeen discharged or the battery hasbeen disconnected. Clock (See Chapter 3)
 Climate control system (See Chapter 4)
 Audio (See Chapter 3)
 Sunroof (See Chapter 3)
(Continued)
 When lifting a plastic-cased bat- tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
 Never attempt to charge the bat- tery when the battery cables are
connected.
 The electrical ignition system works with high voltage. Never
touch these components with the
engine running or the ignition
switched on.
Failure to follow the above warn-
ings can result in serious bodily
injury or death.

4. Tire ply composition and mate-rialThe number of layers or plies of rub-
ber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible inflationpressureThis number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.6. Maximum load ratingThis number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.7. Uniform tire quality grading The following information relates to
the tire grading system developed by
the Canada Motor Vehicle Safety
Stardard (CMVSS) for grading tires
by tread wear, traction and tempera-
ture performance. Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times as well on the government
course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use. However, performance
may differ from the norm because of
variations in driving habits, service
practices and differences in road
characteristics and climate.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on Kia vehicles
may vary with respect to grade.
WARNING -
Tire age
A tire more than 6 years old may
sustain separation of cord lay-
ers inside the tire. Tire failure to
separation of cord, can cause
accidents resulting in severe
injuries or death.
Make sure to check the manu-
facturing date of the tire and
replace it within 6 years of that
date.
