Maintenance
Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
Use only UNLEADED FUEL forgasoline engines.
Do not operate the vehicle when there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
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 con-
trol system. All inspections and
adjustments must be made by an
authorized Kia dealer.
Avoid driving with an extremely low fuel level. Running out of fuel could
cause the engine to misfire, dam-
aging the catalytic converter. Failure to observe these precautions
could result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.

Notice to California Vehicle Dismantlers:
Perchlorate containing materials,
such as air bag inflators, seatbelt

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 SM engine oil is not available, you can use API SN or above.
*4If the ILSAC GF-4 engine oil is not available, you can use ILSAC GF-5 or above.

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 perform-
ance; however, higher viscosity
engine oils are required for satisfacto-
ry lubrication in hot weather. Using
oils of any viscosity other than those
recommended could result in engine
damage. When choosing an oil, con-
sider the range of temperature your
vehicle will be operated in before the
next oil change. Proceed to select the
recommended oil viscosity from the
chart.

the terms, conditions and exclusions set forth in the Kia
Warranty and Consumer Information Manual applicable
to your model year vehicle.
KMA reserves the right to limit or deny services or other
benefits to any owner or driver when, in KMA's judgment,
the claims and/or service requests are excessive in fre-
quency or type of occurrence.
Toll free consumer assistance
Kia's toll-free Consumer Assistance hot line is staffed
from 5:00 AM to 6:00 PM PST, Monday through Friday

one to deliver a small quantity of gas, change a flat tire
with your inflated spare, or arrange a battery jump to
allow you to proceed to your destination. We have access
to a network of over 10,000 locksmiths to help you should
you become locked out of your Kia.

Registering your vehicle in a foreign country
If you plan to register your vehicle in a foreign country,
you should confirm that it conforms to the regulations in
that country. Even if you successfully register the vehicle
in a foreign country, you may experience the following
problems and should therefore consider the possibility of
having to deal with them:
1. The fuel specified for your vehicle may be unavailable.If other than the specified fuel is used, it could cause
damage to the engine, the fuel injection system, and
other fuel-related parts which may not be covered
under your New Vehicle Emissions Limited Warranty.
2. We must, therefore, clearly state that when you leave the country in which you purchased your Kia new and
register it in another country, problems arising from the
use of fuel other than the specified fuel are not subject
to manufacturer’s warranty. Because vehicles like
yours may not be marketed in the new country of reg-
istration, parts, servicing techniques and tools neces-
sary to maintain and repair your vehicle may be
unavailable.
Even if vehicles like yours are sold there, mechanical
specifications required by the government may vary
enough from the country of purchase to cause addi-
tional problems. 3. There may not be an Authorized Kia Dealer in the area
in which you plan to register your vehicle. You may
additionally experience difficulty in obtaining services
in a foreign country for any number of reasons.
Further, we cannot assume any responsibility for prob-
lems that result from unsatisfactory service or lack of
service outside of the United States.
