Operation Tips
To keep dust or unpleasant fumes
from entering the vehicle through
the ventilation system, temporarily
set the air intake control to the
recirculated air position. Be sure to
return the control to the fresh air
position when the irritation has
passed to keep fresh air in the
vehicle. This will help keep the driv-
er alert and comfortable.
Air for the heating/cooling system
is drawn in through the grilles just
ahead of the windshield. Care
should be taken that these are not
blocked by leaves, snow, ice or
other obstructions.
To prevent interior fog on the wind-
shield, set the air intake control to
the fresh air position and fan speed
to the desired position, turn on the
air conditioning system, and adjust
the temperature control to desired
temperature.Air conditioning
All Kia Air Conditioning Systems are
filled with R-1234yf refrigerant.
1.Start the engine. Press the air con-
ditioning button.
2.Set the mode to the position.
3.Set the air intake control to the out-
side air or recirculated air position.
4.Adjust the fan speed control and
temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
extreme left position, set the mode
control to the MAX A/C position,
then set the fan speed control to
the highest speed.CAUTION - Excessive A/C
Use
When using the air conditioning
system, monitor the tempera-
ture gauge closely while driving
up hills or in heavy traffic when
outside temperatures are high.
Air conditioning system opera-
tion may cause engine over-
heating. Continue to use the
blower fan but turn the air con-
ditioning system off if the tem-
perature gauge indicates engine
overheating.
CAUTION
When opening the windows in
humid weather, air conditioning
may create water droplets
inside the vehicle. Since exces-
sive water droplets may cause
damage to electrical equipment,
air conditioning should only be
used with the windows closed.

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
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.
✽ ✽
NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent air
conditioner filter inspections and
changes are required.
• When the air flow rate suddenly
decreases, the system should be
checked at an authorized Kia
dealer.

CAUTION - AC Repair
It is important that the correct
type and amount of oil and
refrigerant is used, otherwise
damage to the vehicle may
occur. To prevent damage, the
air conditioning system in your
vehicle should only be serviced
by trained and certified techni-
cians.

Features of your vehicle
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air condi-
tioning is reduced. Overfilling also
has a negative impact on the air con-
ditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized Kia dealer.
WARNING - Vehicles
equipped with R-1234yf
Since the refrigerant
is mildly flammable
and operated at high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and
certified technicians.
(Refer to the SAE
J2845)
It is important that the correct
type and amount of oil and
refrigerant are used.
All refrigerants should be
reclaimed with proper equip-
ment.
Venting refrigerants directly to
the atmosphere is harmful to
individuals and environment.
Failure to heed these warnings
can lead to serious injuries.

Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and dam-
age.When checking engine oil, engine
coolant, brake fluid, and washer fluid,
always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant or fluid. This is espe-
cially important in dusty or sandy
areas and when the vehicle is used
on unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine and
other mechanisms that could be
damaged.
CHECKING FLUID LEVELS

Maintenance

Engine coolant
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between MAX and MIN 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 protec-
tion against freezing and corrosion.
Bring the level to MAX, but do not
overfill. If frequent additions are
required, see an authorized Kia deal-
er for a cooling system inspection.
Inverter coolant
The coolant level should be filled
between MAX and MIN 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 protec-
tion against freezing and corrosion.
Bring the level to MAX, but do not
overfill. If frequent additions are
required, see an authorized Kia deal-
er for a cooling system inspection.
WARNING- Cooling fan
Use caution when
working near the
blade of the cooling
fan. The electric
motor (cooling fan) is
controlled by engine coolant
temperature, refrigerant pres-
sure and vehicle speed. it may
sometimes operate even when
the engine is not running.
