Maintenance
EMISSION CONTROL SYSTEM (IF EQUIPPED)
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Service Passport
in your vehicle.
Your vehicle is equipped with an emis-
sion control system to meet all applicable
emission regulations. There are three emission control sys-
tems, as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system(3) Exhaust emission control system In order to assure the proper function of
the emission control systems, it is rec-
ommended that you have your car
inspected and maintained by an author-
ized KIA dealer in accordance with the
maintenance schedule in this manual. Caution for the Inspection and
Maintenance Test (With Electronic
Stability Program (ESP) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability
Program (ESP) system off by press-
ing the ESP switch.
After dynamometer testing is com- pleted, turn the ESP system back on
by pressing the ESP switch again. 1. Crankcase emission control
system
The positive crankcase ventilation sys-
tem 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 valveinto the induction system.
2. Evaporative emission control 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 surge tank
through the purge control solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es so that evaporated fuel is not taken
into the engine. After the engine warms-
up during ordinary driving, the PCSV
opens to introduce 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 performance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could affect
its performance, safety or durability and
may even violate governmental safety
and emissions regulations.
In addition, damage or performance
problems resulting from any modification
may not be covered under warranty.
Engine exhaust gas precautions (car- bon 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 sus-
pect 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 car-
bon monoxide (CO). Though color-
less and odorless, it is dangerousand could be lethal if inhaled.
Follow the instructions on this
page to avoid CO poisoning.

Maintenance
Do not operate the engine in confinedor 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 theemission control system.Operating precautions for catalytic
converters (if equipped)
Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
Make sure to refuel your vehicle according to the "Fuel requirements" suggested in section 1.
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 withthe 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 minutesor 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 extremly low fuel level. Running out of fuel could cause
the engine to misfire, damaging the
catalytic converter.
Failure to observe these precautionscould 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.

RECOMMENDED LUBRICANTS AND CAPACITIES
* 1
: Refer to the recommended SAE viscosity numbers on the next page.
* 2
: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econ -
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.
* 3
: If the API service SM engine oil is not available in your country, you are able to use API service SL.
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.

Specifications & Consumer information
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 especially
important in dusty or sandy areasand when the vehicle is used onunpaved roads. Cleaning the plugand dipstick areas will prevent dirt
and grit from entering the engine and other mechanisms that couldbe damaged.

: For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE
5W-20* 2
(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.
