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 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 extremely low fuel level. Running out of fuel could cause
the engine to misfire, damaging 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, vegeta-
tion, paper, leaves, etc.
The exhaust system and catalytic system are very hot while the
engine is running or immediately
after the engine is turned off. Keep
away from the exhaust system
and catalytic, you may get burned.
Also, do not remove the heat sink
around the exhaust system, do
not seal the bottom of the vehicle
or do not coat the vehicle for cor-
rosion control. It may present a
fire risk under certain conditions.

RECOMMENDED LUBRICANTS AND CAPACITIES
To 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.

3If the API service SM engine oil is not available in your country, you are able to use API service SL.

Recommended 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 couldbe damaged.

*1. For better fuel economy, it is recommended to use the engine oil of
a viscosity grade SAE 5W-20 (API SM / ILSAC GF-4). However, if
the engine oil is not available in your country, select the proper
engine oil using the engine oil viscosity chart.

The tires supplied on your new vehicle
are chosen to provide the best perform-
ance for normal driving.
The tire label located on the driver's side
center pillar gives the tire pressures rec-
ommended for your vehicle.The engine number is stamped on the
engine block as shown in the drawing.
