Air conditioning
Kia Air Conditioning Systems are
filled with R-1234yf refrigerant.
1. Start the engine. Push the air con-
ditioning button.
2. Set the mode to the position.
3. Set the air intake control to the recirculated air position. However,
prolonged operation in the recircu-
lated air position will excessively
dry the air. In this case, change the
air position.
4. Adjust the fan speed control and temperature control to maintain
maximum comfort.
The refrigerant system should only be serviced by trained and certified
technicians to ensure proper and
safe operation.
The refrigerant system should be serviced in a well-ventilated place.
The air conditioning evaporator (cooling coil) shall never be
repaired or replaced with one
removed from a used or salvaged
vehicle and new replacement MAC
evaporators should be certified
(and labeled) as meeting SAE
Standard J2842.
✽ ✽ NOTICE
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 equip-
ment, air conditioning should only be
used with the windows closed.
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 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 for a few minutes to
ensure maximum system perform-
ance.
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
operating characteristic of the sys-
tem.CAUTION - Excessive A/C
While using the air conditioningsystem, monitor the tempera-ture gauge closely while drivingup hills or in heavy traffic whenoutside temperatures are high.Air conditioning system opera-tion may cause engine over-heating and potential enginedamage. Continue to use theblower fan but turn the air con-ditioning system off if the tem-perature gauge indicates engineoverheating.

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

tem.
Use the air conditioning system every month for a few minutes to
ensure maximum system perform-
ance.
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
operating characteristic of the sys-
tem. 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
operating characteristic of the sys-
tem.
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.CAUTION
When using the air condition- ing system, monitor the tem-perature gauge closely whiledriving up hills or in heavy traf-fic when outside temperaturesare high. Air conditioning sys-tem operation may causeengine overheating. Continueto use the blower fan but turnthe air conditioning system offif the temperature gauge indi-cates engine overheating.
When opening the windows in humid weather air conditioningmay create water dropletsinside the vehicle. Since exces-sive water droplets may causedamage to electrical equip-ment, air conditioning shouldonly be used with the windowsclosed.

Driving your vehicle
Hazardous driving conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud, sand, or similar haz-
ards, follow these suggestions:
Drive cautiously and allow extradistance 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
vehicle equipped with ABS.
If stalled in snow, mud, or sand,
use second gear. Accelerate slow-
ly to avoid spinning the drive
wheels.
Use sand, rock salt, tire chains, or other non-slip material under the
drive wheels to provide 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 Transmission or R
(Reverse) and any forward gear in
vehicles equipped with an Intelligent
Variable Transmission. 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 overheating and possible
damage to the transmission.
The ESC system should be turned
OFF prior to rocking the vehicle.
SPECIAL DRIVING CONDITIONS
CAUTION- Vehicle
rocking
Prolonged rocking may causeengine overheating, transmis-sion damage or failure, and tiredamage.
WARNING- Downshifting
Do not downshift with an intelli-
gent variable transmission
while driving on slippery sur-
faces. The sudden change in
tire speed could cause the tires
to skid and result in an acci-
dent.

Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
affected.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with
the off-road conditions where you
are going to drive before you begin
driving.
Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on the tires.
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.
WARNING- Under/Over Inflated Tires
Always check the tires for prop-
er inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a
loss of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, you should:
1. Pull off the road and stop as soonas it is safe to do so.
2. Place the shift lever in P (Intelligent Variable Transmission)
or neutral (Manual Transmission)
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 com-
ing 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 operating. 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 condi-
tioning 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 bro- ken or engine coolant leaks, stop
the engine immediately and call
the nearest authorized Kia dealer
for assistance. 6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized 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.
