Cleaning the upholstery and inte-
rior trim
Vinyl
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric
Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately with a fabric spot cleaner. If
fresh spots do not receive immediate
attention, the fabric can be stained
and its color can be affected. Also, its
fire-resistant properties can be
reduced if the material is not proper-
ly maintained.
Using anything but recommended
cleaners and procedures may affect
the fabric’s appearance and fire-
resistant properties.
Cleaning the lap/shoulder beltwebbing
Clean the belt webbing with any mild
soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the
soap. Do not bleach or re-dye the
webbing because this may weaken
it.
Cleaning the interior windowglass
If the interior glass surfaces of the
vehicle become fogged (that is, cov-
ered with an oily, greasy or waxy
film), they should be cleaned with
glass cleaner. Follow the directions
on the glass cleaner container.
CAUTION - Rear windows
Do not scrape or scratch theinside of the rear window. Thismay result in damage to the rearwindow defroster grid.

Maintenance
EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the
Warranty & Consumer Information
manual 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 system
In order to assure the proper function
of the emission control systems, it is
recommended that you have your
vehicle inspected and maintained by
an authorized Kia dealer in accor-
dance with the maintenance sched-
ule 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 (including ORVR:
Onboard Refueling Vapor
Recovery)
system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
(The ORVR system is designed to
allow the vapors from the fuel tank to
be loaded into a canister while refu-
eling at the gas station, preventing
the escape of fuel vapors into the
atmosphere.)

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 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 evap-
orated 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 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 vehi-
cle, 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.

7101
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 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 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 to
the 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: Use only UNLEADED FUEL for
gasoline 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.
WARNING- Fire
Do not park, idle or drive the vehicle over or near flamma-
ble objects, such as grass,
vegetation, paper, leaves, etc.
A hot exhaust system can
ignite flammable items under
your vehicle.
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.
WARNING- Catalytic
converter
Keep away from the catalytic
converter and exhaust system
while the vehicle is running or
immediately thereafter. The
exhaust and catalytic systems
are very hot and may burn you.
