What to do in an emergency
6. If you cannot find the cause of theoverheating, 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 over heating happens again,
call the nearest authorized Kia
dealer for assistance.
✽ ✽NOTICE
Serious loss of coolant indicates
there is a leak in the cooling system
and should be checked as soon as
possible by an authorized Kia dealer.
CAUTION
When the engine overheats from
low engine coolant, suddenlyadding engine coolant maycause cracks in the engine. Toprevent damage, add enginecoolant slowly in small quantities
WARNING- Radiator Cap
Do not remove the
radiator cap when the
engine is hot. This
can allow coolant to
blow out of the open-
ing and cause seri-
ous burns.

Maintenance
(Continued)
• Wash the undercarriage of yourvehicle regularly during the win-
ter and whenever your vehicle has
been exposed to such salts or
chemicals.
• Do a thorough washing of the undercarriage at the end of the
winter.
• Use professional service techni- cians or governmental inspection
stations to annually inspect for
corrosion.
• Immediately seek an inspection of your vehicle if you become visual-
ly aware of corrosion flaking or
scaling or if you become aware of
a change in vehicle performance,
such as soft or spongy brakes, flu-
ids leaking, impairment of direc-
tional control, suspension noises
or rattling metal straps.
NHTSA further advises that after
a vehicle is 7 years old, it is essen-
tial that you take these indicated
maintenance steps to ensure that
you protect yourself from unsafe
corrosion conditions.Owner maintenance precau-
tions
Improper or incomplete service may
result in problems. This section gives
instructions only for the maintenance
items that are easy to perform.
As explained earlier in this section,
several procedures can be done only
by an authorized Kia dealer with spe-
cial tools.
✽ ✽ NOTICE
Improper owner maintenance dur-
ing the warranty period may affect
warranty coverage. For details, read
the separate Warranty & Consumer
Information manual provided with
the vehicle. If you're unsure about
any servicing or maintenance proce-
dure, have it done by an authorized
Kia dealer.
WARNING- Maintenance
work
Do not wear jewelry or loose
clothing while working under
the hood of your vehicle with
the engine running. These can
become entangled in moving
parts, if you must run the
engine while working under the
hood, make certain that you
remove all jewelry (especially
rings, bracelets, watches, and
necklaces) and all neckties,
scarves, and similar loose
clothing before getting near the
engine or cooling fans.

Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
A Genuine Kia air cleaner filter is
recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check the cooling system compo-
nents, such as the radiator, coolant
reservoir, hoses and connections for
leakage and damage. Replace any
damaged parts.
Coolant (Engine / Inverter)
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Dual clutch transmission Fluid
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.

Maintenance
COOLANT
The high-pressure cooling system
has a reservoir filled with year round
antifreeze 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 before traveling to a colder cli-
mate.Checking the coolant level Turn the engine off and wait until itcools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the cool-
ing system.
When you are sure all the pressure
has been released, press down on
the cap, using a thick towel, and
continue turning counterclockwise
to remove it.
Even if the engine is not operating, do not remove the radiator cap or
the drain plug while the engine and
radiator are hot. Hot coolant and
steam may still blow out under
pressure, 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 inverter coolant,
turn the hybrid vehicle off.
WARNING
Removing radiator
cap
Never attempt to remove the
radiator cap while the engine is
operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal injury
from escaping hot coolant or
steam.
CAUTION - Radiator cap
Never attempt to remove theradiator cap while the engine isoperating or hot. Doing somight lead to cooling systemand engine damage.

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.
