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.
To help reduce moisture inside of the windows on rainy or humid days,
decrease the humidity inside the vehi-
cle by operating the air conditioning
system.
During air conditioning system opera- tion, 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 sys- tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic. Operating the air conditioning system
in the recirculated air position provides
maximum cooling, however, 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 opera-
tion characteristic.
Climate control air filter
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) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized Kia dealer.

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
the inside of the windshield.
Automatic climate control system
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 corre-
sponding button manually.
WINDSHIELD DEFROSTING AND DEFOGGING
WARNING - Windshield heating
Do not use the or position
during cooling operation to redure
fog up in extremely humid weather.

Driving your vehicle
Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, follow
these suggestions:
Drive cautiously and allow extra dis-tance for braking.
Avoid sudden braking or steering.
When braking with non-ABS brakes pump the brake pedal with a light up-
and-down motion until the vehicle is
stopped. Do not pump the brake pedal on a vehi-
cle equipped with ABS.
If stalled in snow, mud, or sand, use
second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, or other non-slip material under the drive wheels to pro-
vide traction when stalled in ice, snow,
or mud.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between 1st (First)
and R (Reverse) in vehicles equipped
with a manual transaxle or R (Reverse)
and any forward gear in vehicles
equipped with an automatic transaxle. Do
not race the engine, and spin the wheels
as little as possible. If you are still stuck
after a few tries, have the vehicle pulled
out by a tow vehicle to avoid engine over-
heating and possible damage to the
transaxle.
The ESC system should be turned OFF
prior to rocking the vehicle.
SPECIAL DRIVING CONDITIONS
WARNING - Downshifting
Do not downshift with an automatic
transaxle while driving on slippery
surfaces. The sudden change in tire
speed could cause the tires to skid
and result in an accident.
CAUTION - Vehicle
rocking
Prolonged rocking may causeengine overheating, transaxle dam-age or failure, and tire damage.

Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
Never exceed the maximum tire inflation
pressure shown on the tires.
Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks of
roots of trees. Become familiar with the
off-road conditions where you are going
to drive before you begin driving.
Fuel, engine coolant and engine oil
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both the engine coolant and
engine oil.
Drive belt
A loose or damaged drive belt may over-
heat the engine.
WARNING - Under/over
inflated tires
Always check the tires for proper
inflation before driving.
Underinflated or overinflated tires
can cause poor handling, loss of
vehicle control, and sudden tire fail-
ure leading to accidents, injuries,
and even death. For proper tire
pressures, refer to “Tires and
wheels” in section 8.
WARNING - Tire tread
Always check the tire tread before
driving your vehicle. Worn-out tires
can result in loss of vehicle control.
Worn-out tires should be replaced
as soon as possible. For further
information and tread limits, refer
to "Tires and wheels" in section 7.

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you will experience a loss of
power, or hear loud pinging or knocking,
the engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as itis safe to do so.
2. Place the shift lever in P (automatic transaxle) or neutral (manual
transaxle) and set the parking brake. If
the air conditioning is on, turn it off.
3. If engine coolant is running out under the vehicle or steam is coming out from
underneath the hood, stop the engine.
Do not open the hood until the coolant
has stopped running or the steaming
has stopped. If there is no visible loss
of engine coolant and no steam, leave
the engine running and check to be
sure the engine cooling fan is operat-
ing. If the fan is not running, turn the
engine off.
4. Check to see if the water pump drive belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from it
when you stop). 5. If the water pump drive belt is broken
or engine coolant leaks, stop the
engine immediately and call the near-
est authorized Kia dealer for assis-
tance. 6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,
if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-
heating happens again, call an author-
ized Kia dealer for assistance.
Serious loss of coolant indicates there is
a leak in the cooling system and this
should be checked as soon as possible
by an authorized Kia dealer.
WARNING - Under the
hood
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts.
WARNING - Radiator cap
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
