EMISSION CONTROL SYSTEM (IF EQUIPPED)
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an emission control system to meet all
applicable emission regulations. There are three emission control
systems, as follows.
(1) Crankcase emission control sys- tem
(2) Evaporative emission control sys- tem
(3) Exhaust emission control systemIn order to assure the proper function
of the emission control systems, it is
recommended that you have your
car inspected and maintained by an
authorized Kia dealer in accordancewith the maintenance schedule in
this manual. Caution for the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
To prevent the vehicle from mis-
firing during dynamometer test-
ing, turn the Electronic Stability
Control (ESC) system off by
pressing the ESC switch.
After dynamometer testing is completed, turn the ESC system
back on by pressing the ESC
switch again. 1. Crankcase emission control
system
The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase.This system supplies fresh filtered air
to the crankcase through the air
intake hose. Inside the crankcase,
the fresh air mixes with blow-by
gases, which then pass through the
PCV valve into the induction system.
2. Evaporative emission con- trol system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.

Canister
Fuel vapors generated inside the fuel tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surgetank through the purge control sole-
noid valve.
Purge Control Solenoid Valve
(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evapo-
rated fuel is not taken into the engine.
After the engine warms-up during ordi-
nary driving, the PCSV opens to intro-
duce evaporated fuel to the engine. 3. Exhaust emission control
system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate gov-
ernmental safety and emissions reg-
ulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic 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 immediately.
WARNING - Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-soning.

Maintenance
Do not operate the engine in con-fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in orout 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 vehicle 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 tothe emission control system.Operating precautions for catalyt-
ic converters (if equipped)Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
Make sure to refuel your vehicle according to the "Fuel require- ments" suggested in section 1.
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 arecoasting 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. We recommend that
the system be inspected by an
authorized Kia dealer.
WARNING - Fire
A hot exhaust system can ignite flammable items under
your vehicle. Do not park, idle,
or drive the vehicle over or
near flammable objects, such
as grass, vegetation, paper,
leaves, etc.
The exhaust system and cat- alytic system are very hotwhile the engine is running or
immediately after the engine
is turned off. Keep away from
the exhaust system and cat-
alytic, you may get burned.
Also, do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle or do not coat the
vehicle for corrosion control.
It may present a fire risk under
certain conditions.

Avoid driving with a extremly lowfuel level. Running out of fuel could
cause the engine to misfire, dam-
aging the catalytic converter.
Failure to observe these precautionscould result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.

omy 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.

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 viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory lubrication in hot weather.Using oils of any viscosity other thanthose recommended could result in
engine damage. When choosing an oil, consider the
range of temperature your vehicle will
be operated in before the next oil
change. Proceed to select the recom-
mended oil viscosity from the chart.
CAUTION
Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing or draining any lubricant.
This is especially important in
dusty or sandy areas and when
the vehicle is used on unpaved
roads. Cleaning the plug and
dipstick areas will prevent dirt
and grit from entering the
engine and other mechanisms
that could be damaged.
