2009 KIA Optima Engine

Maintenance60
7 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.
G270303AUNOperating precautions for catalyticconverters (if equipped)Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
Use only UNLEADED FUEL for gaso- line engines.
Do not operate the vehicle when there are signs of engine malfunction, such
as misfire or a noticeable loss of per-
formance. 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 minutes
or more).
Do not modify or tamper with any part of the engine or emission control sys-
tem. All inspections and adjustments
must be made by an authorized KIA
dealer.
Avoid driving with a very low fuel level. If you run out of gasoline, it could
cause the engine to misfire and result
in excessive loading of 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.
WARNING
- Fire
A hot exhaust system can ignite
flammable items under your vehi-
cle. Do not park, idle, or drive the
vehicle over or near flammable
objects, such as grass, vegetation,
paper, leaves, etc.

Specifications & Consumer information

Specifications, Consumer information48RECOMMENDED LUBRICANTS AND CAPACITIES I040000AMG-ECTo help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality. The correct
lubricants also help promote engine efficiency that results in improved fuel economy.These lubricants and fluids are recommended for use in your vehicle.*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econo my by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.Lubricant Volume Classification

I040100AUN-EURecommended SAE viscosity
number
Engine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operating (engine start and engine oil
flowability). Lower viscosity engine oils
can provide better fuel economy and cold
weather performance, however, higher
viscosity engine oils are required for sat-
isfactory lubrication in hot weather. Using
oils of any viscosity other than those rec-
ommended could result in engine dam-
age.When choosing an oil, consider the range
of temperature your vehicle will be oper-
ated in before the next oil change.
Proceed to select the recommended oil
viscosity from the chart.
CAUTION
Always be sure to clean the area
around any filler plug, drain plug, ordipstick before checking or drain- ing any lubricant. This is especiallyimportant in dusty or sandy areasand when the vehicle is used on unpaved roads. Cleaning the plugand dipstick areas will prevent dirtand grit from entering the engineand other mechanisms that could be damaged.

1. For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE 5W-
20, 5W-30 (API SL, SM / ILSAC GF-3 or above). However, if the engine oil is not available in
your country, select the proper engine oil using the engine oil viscosity chart.

Specifications, Consumer information68H010000AMGThe vehicle identification number (VIN) is
the number used in registering your car
and in all legal matters pertaining to its
ownership, etc.
The number is punched on the engine
compartment bulkhead.The VIN is also on a plate attached to the
top of the dashboard. The number on the
plate can easily be seen through the
windshield from outside.
