COOLANT
The high-pressure cooling system has
a reservoir filled with year round anti‐
freeze coolant. The reservoir is filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and be‐ fore traveling to a colder climate.
CAUTION
•When the engine overheats fromlow engine coolant, suddenly add‐ing engine coolant may causecracks in the engine. To preventdamage, add engine coolant slowlyin small quantities.
•Do not drive with no engine cool‐ant. It may cause water pump fail‐ure and engine seizure, etc.
Checking the coolant level
WARNING
nRemoving radiator cap
•Never attempt to remove the radi‐ator cap while the engine is oper‐ating or hot. Doing so might leadto cooling system and engine dam‐age. Also, hot coolant or steamcould cause serious personal in‐jury.
•Turn the engine off and wait untilit cools down. Use extreme carewhen removing the radiator cap.Wrap a thick towel around it, andturn it counterclockwise slowly tothe first stop. Step back while thepressure is released from the cool‐ing system.When you are sure all the pressurehas been released, press down onthe cap, using a thick towel, andcontinue turning counterclockwiseto remove it.

•Even if the engine is not operating,do not remove the radiator cap orthe drain plug while the engine andradiator are hot. Hot coolant andsteam may still blow out underpressure, causing serious injury.
The engine coolant and/or inverter
coolant level is influenced by the hybrid system temperature. Before checking
or refilling the engine coolant and/or in‐
verter coolant, turn the hybrid vehicle off.
WARNING
The electric motor (cool‐ing fan) is controlled byengine coolant tempera‐ture, refrigerant pressureand vehicle speed. It maysometimes operate evenwhen the engine is notrunning.

Use extreme caution when workingnear the blades of the cooling fan sothat you are not injured by a rotat‐ing fan blades. As the engine coolanttemperature decreases, the electricmotor will automatically shut off.This is a normal condition.If your vehicle is equipped with GDI,the electric motor (cooling fan) mayoperate until you disconnect thenegative battery cable.
Engine coolant
0 + '
Check the condition and connections of
all cooling system hoses and heater ho‐ ses. Replace any swollen or deteriora‐
ted hoses.
The coolant level should be filled be‐
tween F (Full) and L (Low) 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 (Full), but do not overfill.
If frequent additions are required, we
recommend that the system be inspec‐
ted by an authorized Kia dealer.
Inverter coolant
Check the condition and connections of
all cooling system hoses. Replace any swollen or deteriorated hoses.
The coolant level should be filled be‐
tween MAX and MIN marks on the side
of the coolant reservoir when the en‐ gine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the level to MAX, but do not overfill. If
frequent additions are required, we rec‐
ommend that the system be inspected
by an authorized Kia dealer.

WASHER FLUID
Checking the washer fluid level
0 + '
The reservoir is translucent so that you
can check the level with a quick visual
inspection.
Check the fluid level in the washer fluid
reservoir and add fluid if necessary.
Plain water may be used if washer fluid is not available. However, use washer
solvent with antifreeze characteristics
in cold climates to prevent freezing.
WARNING
nCoolant
•Do not use radiator coolant or an‐tifreeze in the washer fluid reser‐voir.
•Radiator coolant can severely ob‐scure visibility when sprayed onthe windshield and may cause lossof vehicle control or damage topaint and body trim.
•Windshield washer fluid agentscontain some amounts of alcoholand can be flammable under cer‐tain circumstances. Do not allowsparks or flame to contact thewasher fluid or the washer fluidreservoir. Damage to the vehicle oroccupants could occur.
•Windshield washer fluid is poison‐ous to humans and animals. Donot drink and avoid contactingwindshield washer fluid. Seriousinjury or death could occur.
