•Working under the hood with theengine running is dangerous. It be‐comes even more dangerous whenyou wear jewelry or loose clothing.These can become entangled inmoving parts and result in injury.Therefore, if you must run the en‐gine while working under the hood,make certain that you remove alljewelry (especially rings, bracelets,watches, and necklaces) and allneckties, scarves, and similar looseclothing before getting near theengine or cooling fans.
CAUTION
•Do not put heavy objects or applyexcessive force on top of the en‐gine cover (if equipped) or fuel re‐lated parts.
•When you inspect the fuel system(fuel lines and fuel injection devi‐ces), we recommend that you con‐tact an authorized kia dealer.

•Do not drive long time with the en‐gine cover (if equipped) removed.
•When checking the engine room,do not go near fire.Fuel, washer fluid, etc. are flam‐mable oils that may cause fire.
•Before touching the battery, igni‐tion cables and electrical wiring,you should disconnect the battery"-" terminal. You may get an elec‐tric shock from the electric cur‐rent.
•When you remove the interior trimcover with a flat bed (-) driver, becareful not to damage the cover.

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-
ahead position.
• Notice if your vehicle constantly turns slightly or L

NORMAL MAINTENANCE SCHEDULE - FOR GASOLINE ENGINE [FOR EUROPE (EXCEPT RUSSIA)]
The following maintenance services must be performed to ensure good emission control and performance. Keep receipts for
all vehicle emission services to protect your warranty. Where both mileage and time are shown, the frequency of service is determined by whichever occurs first.
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.

Maintenance

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.
