OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per‐
formed at the frequencies indicated to help ensure safe, dependable operation

and you may be charged for labor, parts and lubricants used.
Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check the coolant level in the coolant reservoir.
• Check the windshield washer fluid level.
• Look for low or under-inflated tires.
WARNING
Be careful when checking your en‐gine coolant level when the engine ishot. Scalding hot coolant and steam

may blow out under pressure. Thiscould cause burns or other seriousinjury.
While operating your vehicle:
• Note any changes in the sound of the exhaust or any smell of exhaust
fumes in the vehicle.
• Check for vibrations in the steering wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-

• Notice if your vehicle constantly turns slightly or L

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the maintenance schedule. If the vehi‐
cle is being driven in severe conditions,
more frequent oil and filter changes are required.
HSG (hybrid starter &
generator) belt
The HSG belt should be changed at the
intervals specified in the maintenance schedule.
Fuel filter (for gasoline)
Kia gasoline vehicle is equipped a life‐
time fuel filter that integrated with the fuel tank. Regular maintenance or re‐
placement is not needed but depends
on fuel quality. If there are some im‐ portant safety matters like fuel flow
restriction, surging, loss of power, hard
starting problem etc, fuel filter inspec‐ tion or replace is needed.
We recommend that the fuel filter be
Inspected or replaced by an authorized
Kia dealer.
Fuel lines, fuel hoses and
connections
Check the fuel lines, fuel hoses and
connections for leakage and damage. We recommend that the fuel lines, fuel
hoses and connections be replaced by
an authorized Kia dealer.
Vapor hose (for gasoline engine)
and fuel filler cap
The vapor hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapor hose or
fuel filler cap is correctly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi‐
dence of heat and/or mechanical dam‐ age. Hard and brittle rubber, cracking,
tears, cuts, abrasions, and excessive
swelling indicate deterioration. Particu‐ lar 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 contact with
any heat source, sharp edges or mov‐ ing component which might cause heat
damage or mechanical wear. Inspect all
hose connections, such as clamps and couplings, to make sure they are se‐
cure, and that no leaks are present. Ho‐
ses should be replaced immediately if there is any evidence of deterioration
or damage.
Air cleaner filter
We recommend that the air cleaner fil‐
ter be replaced by an authorized Kia dealer.
Spark plugs (for gasoline engine)
Make sure to install new spark plugs of
the correct heat range.
WARNING
Do not disconnect and inspect sparkplugs when the engine is hot. Youmay burn yourself.

2. Start the engine and allow it to reach normal operating tempera‐
ture.
3. Turn the engine off and wait for a few minutes (about 5 minutes) for
the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and re-insert it fully.
WARNING
nRadiator hose
Be very careful not to touch the ra‐diator hose when checking or addingthe engine oil as it may be hotenough to burn you.
5. Pull the dipstick out again andcheck the level. The level should be
between F (Full) and L (Low).
CAUTION
•Do not overfill the engine oil. Itmay damage the engine
•Do not spill engine oil, when addingor changing engine oil. If you dropthe engine oil on the engine room,wipe it off immediately.
•When you wipe the oil level gauge,you should wipe it with a cleancloth. When mixed with debris, itcan cause engine damage.

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.

(Continued)
•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.
