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.

If it fits loosely, we recommend that
you consult an authorized Kia dealer.
If you do not have a spare, use a fuse of the same rating from a circuit you
may not need for operating the vehicle,
such as the cigarette lighter fuse.
If the headlights or taillights, stop lights, courtesy lamp, day time running
lights (D.R.L) do not work and the fuses
are OK, check the fuse panel in the en‐ gine compartment. If a fuse is blown, it
must be replaced.

Always, put the fuse switch at the ON
position. If you move the switch to the OFF posi‐
tion, some items such as audio and dig‐
ital clock must be reset and transmitter
(or smart key) may not work properly.
If the fuse switch is in OFF, a warning sign will illuminate on the dashboard.
CAUTION
•Put all switches in ON when driv‐ing.
•If the vehicle remains idle for over1 month, put all switches in OFF toprevent the batteries from beingdischarged.
•Excluding long-term parking forover 1 month, the contact pointsof switches may wear out uponextensive use. Please refrain fromexcessive use of switches.
Engine compartment fuse
