2017 KIA OPTIMA PLUG-IN HYBRID catalytic converter

FUEL REQUIREMENTS
Gasoline engine
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you to use unleaded gasoline with an octane rating of RON
(Research Octane Number) 95 / AKI
(Antiknock Index) 91 or higher.
You may use unleaded gasoline with an octane rating of RON 91~94 / AKI 87~90
but it may result in slight performance
reduction of the vehicle. (Do not use methanol blended fuels.)
Except Europe
Your new Kia vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane Num‐ ber) 91 / AKI (Antiknock Index) 87 or
higher. (Do not use methanol blended
fuels.)
Your new vehicle is designed to obtain maximum performance with UNLEA‐
DED FUEL, as well as minimize exhaust
emissions and spark plug fouling.
CAUTION
NEVER USE LEADED FUEL. The useof leaded fuel is detrimental to thecatalytic converter and will damagethe engine control system’s oxygensensor and affect emission control.Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (We recom‐mend that you consult an authorizedKia dealer for details.)
WARNING
•Do not "top off" after the nozzleautomatically shuts off when re‐fueling.
•Always check that the fuel cap isinstalled securely to prevent fuelspillage in the event of an acci‐dent.
Leaded (if equipped)
For some countries, your vehicle is de‐
signed to use leaded gasoline. When you are going to use leaded gasoline,
we recommend that you ask an au‐
thorized Kia dealer whether leaded gasoline in your vehicle is available or
not.
Octane Rating of leaded gasoline is
same with unleaded one.
Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol), and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or in‐ stead of leaded or unleaded gasoline.
Do not use gasohol containing more
than 10% ethanol, and do not use gas‐
oline or gasohol containing any metha‐ nol. Either of these fuels may cause
drivability problems and damage to the
fuel system, engine control system and emission control system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability problems
may not be covered by the manufac‐ turer’s warranty if they result from the
use of:

Introduction

(Continued)
In this case, we recommend you
have the vehicle inspected by an au‐
thorized Kia dealer as soon as possi‐
ble.
WARNING
nElectronic Brake force Distri‐bution (EBD) System WarningLight
When both ABS and Parking Brake &Brake Fluid Warning Lights are on,the brake system will not work nor‐mally and you may experience anunexpected and dangerous situationduring sudden braking.In this case, avoid high speed drivingand abrupt braking.We recommend you have the vehicleinspected by an authorized Kia deal‐er as soon as possible.
Electronic power steering
(EPS) warning light (if
equipped)
This warning light illumi‐nates:
• Once you set the Engine Start/Stop Button to the ON position.- It remains on until the engine is started.
• When there is a malfunction with the EPS.
In this case, we recommend that you
have the vehicle inspected by an au‐
thorized Kia dealer.
Malfunction indicator
lamp (MIL)
This warning light illumi‐nates:
• Once you set the Engine Start/Stop Button to the ON position.- It remains on until the engine is started.
• When there is a malfunction with the emission control system.
In this case, we recommend that you
have the vehicle inspected by an au‐
thorized Kia dealer.
CAUTION
nMalfunction Indicator Lamp(MIL)
Driving with the Malfunction Indica‐tor Lamp (MIL) on may cause dam‐age to the emission control systemswhich could effect drivability and/orfuel economy.
CAUTION
nGasoline Engine
If the Malfunction Indicator Lamp(MIL) illuminates, potential catalyticconverter damage is possible whichcould result in loss of engine power.In this case, we recommend that youhave the vehicle inspected by an au‐thorized Kia dealer as soon as possi‐ble.
Charging system warning
light
This warning light illumi‐nates:
• Once you set the Engine Start/Stop Button to the ON position.

Features of your vehicle

• If you use unauthorized electronicdevices, it may cause the vehicle to
operate abnormally, wire damage, battery discharge and fire. For your
safety, do not use unauthorized elec‐
tronic devices.
Engine exhaust gas precautions
(carbon monoxide)
• Carbon monoxide can be present with other exhaust fumes. Therefore, if
you smell exhaust fumes of any kind inside your vehicle, have it inspected
and repaired immediately. If you ever
suspect exhaust fumes are coming
into your vehicle, drive it only with all
the windows fully open. Have your vehicle checked and repaired immedi‐
ately.
WARNING
nExhaust
Engine exhaust gases contain carbonmonoxide (CO). Though colorless andodorless, it is dangerous and couldbe lethal if inhaled. Follow the in‐structions on this page to avoid COpoisoning.
• Do not operate the engine in confined or closed areas (such as garages) any
more than what is necessary to move the vehicle in or out of the area.
• When the vehicle is stopped in an open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to
draw outside air into the vehicle.
• Never sit in a parked or stopped vehi‐ cle for any extended time with the
engine running.
• When the engine stalls or fails to start, excessive attempts to restart
the engine may cause damage to the
emission control system.
Operating precautions for catalytic
converters (if equipped)
WARNING
nFire
(Continued)
(Continued)
•A hot exhaust system can igniteflammable items under your vehi‐cle. Do not park the vehicle over ornear flammable objects, such asgrass, vegetation, paper, leaves,etc.
•The exhaust system and catalyticsystem are very hot while the en‐gine is running or immediately af‐ter the engine is turned off. Keepaway from the exhaust systemand catalytic, you may get burned.Also, do not remove the heat sinkaround the exhaust system, donot seal the bottom of the vehicleor do not coat the vehicle for cor‐rosion control. It may present afire risk under certain conditions.
Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions must be observed: • Make sure to refuel your vehicle ac‐ cording to the L

• Do not misuse or abuse the engine.Examples of misuse are coasting with
the ignition off and descending steep grades in gear with the ignition off.
• Do not operate the engine at high idle speed for extended periods (5 mi‐
nutes or more).
• Do not modify or tamper with any part of the engine or emission control
system. All inspections and adjust‐ ments must be made by an author‐
ized Kia dealer.
• Avoid driving with an extremely low fuel level. Running out of fuel could
cause the engine to misfire, damag‐
ing the catalytic converter.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void your warranties.
