WARNING
nENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open thewindows immediately.•Do not inhale exhaust fumes.Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyx‐iation.
•Be sure the exhaust system does not leak.The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose.If you hear a change in the sound of the exhaust or if you drive over something that strikes the underneath side of thevehicle, we recommend that the system be checked by an authorized Kia dealer.
•Do not run the engine in an enclosed area.Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine inyour garage any longer than it takes to start the engine and back the vehicle out.
•Avoid idling the engine for prolonged periods with people inside the vehicle.If it is necessary to idle the engine for a prolonged period with people inside the vehicle, be sure to do so only in an openarea with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interi‐or.
If you must drive with the tailgate/trunk open because you are carrying objects that make this necessary:1.Close all windows.
2.Open side vents.
3.Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the wind‐shield are kept clear of snow, ice, leaves or other obstructions.

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.
