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 a 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.

ardouswaste/ perchlorate.
Notice to California Vehicle Dismantlers:
Perchlorate containing materials,
such as air bag inflators, seatbelt
pretensioners and keyless remote

according to Title 22 California Code
of Regulations Section 67384.10 (a).
