NO.ITEMREMARK
*1 Coolant (Engine/Inverter) When adding coolant, use only deionized water or soft water for your vehicle
and never mix hard water in the coolant filled at the factory. An improper
coolant mixture can result in serious malfunction or engine damage.
*2 Engine oil and engine oil filter Check the engine oil level and leak every 500 km (350 miles) or before start‐ing a long trip.
*3 Fuel additives (Gasoline) Kia recommends that you use unleaded gasoline which has an octane rating
of RON (Research Octane Number) 95 / AKI (Antiknock Index) 91 or higher
(for Europe) or Octane Rating of RON (Research Octane Number) 91 / AKI(Antiknock Index) 87 or higher (except Europe).
For customers who do not use good quality gasolines including fuel additives
regularly, and have problems starting or the engine does not run smoothly,
one bottle of additives added to the fuel tank at every 15,000 km (for Eu‐rope, Australia and New Zealand)/10,000 km (except Europe, Australia andNew Zealand).
Additives are available from your authorized Kia dealer along with informa‐
tion on how to use them. Do not mix other additives.
*4 HSG (Hybrid Starter & Generator) belt Inspect HSG belt for evidence of cuts, crocks, excessive wear or oil saturation
and replace if necessary. If drive belt noise occurred, readjust drive belt ten‐
sion before replace.
*5 Spark plug For your convenience, it can be replaced prior to it's interval when you domaintenance of other items.

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.

Cooling system
Check the cooling system components,
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 maintenance schedule.
Automatic transaxle fluid
Automatic transaxle fluid should not be
checked under normal usage conditions.
We recommend that the automatic transmission fluid changed by an au‐
thorized Kia dealer according to the
maintenance schedule.
NOTICE
Automatic transaxle fluid color is ba‐
sically red.
As the vehicle is driven, the auto‐
matic transaxle fluid will begin to
look darker. It is normal condition
and you should not judge the need
to replace the fluid based upon the
changed color.
CAUTION
The use of a non-specified fluidcould result in transaxle malfunctionand failure.Use only specified automatic trans‐axle fluid (Refer to L

4. Lock the cover with the reverse or‐der.
Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extremely dusty or sandy areas, replace the ele‐
ment more often than the usual rec‐
ommended intervals. (Refer to L

CLIMATE CONTROL AIR FILTER
Filter inspection
The climate control air filter should bereplaced according to the maintenance
schedule. If the vehicle is operated in
severely air-polluted cities or on dusty rough roads for a long period, it should
be inspected more frequently and re‐
placed earlier. When you replace the cli‐ mate control air filter, replace it per‐
forming the following procedure, and
be careful to avoid damaging other components.
